1. Introduction: The rise of new energy vehicles and security challenges

With the increasing global awareness of environmental protection, new energy vehicles (NEVs) have become an important development direction of the automotive industry. However, in this “green revolution”, battery safety issues have always been an unavoidable topic. In recent years, fire accidents caused by thermal out-of-control of batteries have been common, which not only threatens the lives and safety of drivers and passengers, but also has caused considerable obstacles to the development of the new energy vehicle industry.

To solve this problem, scientists have turned their attention to fireproof isolation technology. In this technology, bis(dimethylaminoethyl)ether (BDMAEE) is playing an irreplaceable role as an efficient foaming catalyst. It is like an invisible guardian, silently protecting the safe operation of new energy vehicles. So, what exactly is BDMAEE? How does it help fireproof isolation technology? Next, let us unveil its mystery together.

2. Introduction to Bis(dimethylaminoethyl) ether (BDMAEE)

2.1 Chemical Properties

Bis(dimethylaminoethyl) ether (BDMAEE), with the chemical formula C8H20N2O, is an organic compound with strong alkalinity. As a type of amine compounds, BDMAEE can promote the occurrence of chemical reactions through its unique molecular structure, especially in foamingExcellent catalytic performance was shown during the process.

  • Molecular Weight: 156.26 g/mol
  • Melting point: -30°C
  • Boiling point: 220°C
  • Density: 0.92 g/cm³

BDMAEE’s molecular structure contains two dimethylaminoethyl groups. This special structure gives it strong nucleophilicity and reactivity, making it an indispensable catalyst in many industrial fields.

2.2 Physical parameters

The following are some key physical parameters of BDMAEE:

parameter name value Unit
Appearance Colorless to light yellow liquid
Solution Easy soluble in water, alcohols, etc.
Vapor Pressure 0.01 kPa
Flashpoint 85 °C

These parameters show that BDMAEE not only has good stability, but also has high safety, making it very suitable for use in complex industrial environments.

3. Application of BDMAEE in foaming catalysts

3.1 Analysis of foaming process

Foaming is the process of introducing gas into liquid or solid materials to form a porous structure. In new energy vehicle battery packs, foaming materials are usually used as heat insulation to prevent heat transfer between battery modules. As a foaming catalyst, BDMAEE’s main function is to accelerate the progress of foaming reactions, thereby improving production efficiency and material performance.

Basic Principles of Foaming Reaction

The foaming reaction can be summarized simply into the following steps:

  1. Initial Stage: BDMAEE reacts with isocyanate to form active intermediates.
  2. Expandation stage: The active intermediate further reacts with the polyol to form a polymer backbone.
  3. Currecting Stage: The polymer skeleton is gradually crosslinked to finally form a stable foam structure.

In this process, BDMAEE is like a “commander”, accurately controlling the speed and direction of each step of reaction, ensuring that the resulting foam material has ideal density, strength and thermal insulation properties.

3.2 Catalyst performance parameters

To better understand the catalytic performance of BDMAEE, we can refer to the following data:

Performance metrics Value Range Unit
Catalytic Efficiency 95%-99% %
Foam density 30-50 kg/m³
Thermal conductivity 0.02-0.03 W/(m·K)
Dimensional stability ±0.5% %

It can be seen from the table that the application of BDMAEE not only improves the comprehensive performance of foam materials, but also greatly reduces production costs.

4. Core principles of fireproof isolation technology

4.1 Thermal runaway mechanism

The so-called thermal runaway refers to the phenomenon of a sharp rise in the internal temperature of the battery, leading to a series of chain reactions. Once a battery cell gets thermally out of control, the heat it releases may spread rapidly to the adjacent cell, eventually causing the entire battery pack to burn or even explode.

The main causes of thermal runaway

  • Overcharge/overdischarge: Too much current or too high voltage may cause a short circuit inside the battery.
  • External impact: Collision or squeezing may cause the battery housing to rupture.
  • High Temperature Environment: Extreme high temperatures will accelerate the internal chemical reaction of the battery.

4.2 Selection and design of isolation materials

In response to the problem of thermal runaway, scientists have developed a series of high-performance isolation materials. Among them, the thermal insulation layer based on BDMAEE foaming technology is highly favored for its excellent flame retardancy and thermal insulation properties.

Design Principles

  1. High thermal resistance: Ensure that heat is not easily transferred to adjacent battery cells.
  2. Low density: Reduce overall weight and improve vehicle endurance.
  3. High temperature resistance: It can maintain stable performance under extreme conditions.

Through reasonable design, these isolation materials can effectively prevent the spread of thermal runaway at critical moments, and gain valuable escape time for drivers and passengers.

5. Specific application of BDMAEE in battery packs of new energy vehicles

5.1 The importance of battery thermal management

In new energy vehicles, battery thermal management system (BTMS) plays a crucial role. It not only monitors the working status of the battery, but also adjusts the temperature to avoid excessively high or too low temperatures affecting battery performance. And BDMAEE foaming material is an indispensable part of this system.

Application Scenarios

  • Isolation between Battery Modules: By filling the battery cells with BDMAEE foaming material, heat transfer can be effectively reduced.
  • Case protection: Adding a layer of BDMAEE foaming material inside the shell can improve the impact resistance and fire resistance of the entire battery pack.

5.2 BDMAEE enhances the effect of fireproof isolation

Experimental data show that battery packs using BDMAEE foaming material show significant advantages in the face of thermal runaway. For example, in simulated collision tests, a battery pack equipped with a BDMAEE foam layer successfully prevented the spread of the flame, while a severe fire occurred in the control group without the material.

Test items Using BDMAEE Material BDMAEE material not used
Flame spread time >30 minutes <5 minutes
Temperature peak 120°C 300°C
Smoke production Traced mass

It can be seen that BDMAEE foaming material does have outstanding performance in fireproof isolation.

6. Research progress and case analysis at home and abroad

6.1 Current status of domestic research

In recent years, domestic scientific research institutions and enterprises have made significant progress in BDMAEE foaming technology. For example, a well-known battery manufacturer successfully developed a new thermal insulation material by optimizing the BDMAEE formula, with a thermal conductivity of only 0.02 W/(m·K), which is far lower than the industry average.

In addition, a study from Tsinghua University shows that by adjusting the dosage of BDMAEE, the porosity and mechanical strength of foam materials can be accurately controlled, thereby meeting the needs of different application scenarios.

6.2 International Research Trends

In foreign countries, BDMAEE foaming technology has also received widespread attention. A US startup has developed a self-healing insulation using BDMAEE, which automatically restores its insulation properties even after damage. The German research team focuses on exploring the synergistic effects of BDMAEE and other functional additives, striving to further improve the comprehensive performance of the material.

7. Technology advantages and future prospects

7.1 Technical Advantages

  • High-efficiency Catalysis: BDMAEE can significantly speed up the foaming reaction speed and improve production efficiency.
  • Excellent performance: The foam material prepared by BDMAEE has good thermal insulation, flame retardant and shock absorption properties.
  • Green and Environmentally friendly: Compared with traditional foaming catalysts, BDMAEE is more friendly to the human body and the environment.

7.2 Future Outlook

As the new energy vehicle market continues to expand, the application prospects of BDMAEE foaming technology are becoming more and more broad. In the future, scientists will continue to delve into the catalytic mechanism of BDMAEE and try to combine it with other advanced materials to develop more high-performance products. At the same time, with the continuous improvement of production processes, the cost of BDMAEE is expected to be further reduced, thereby promoting its widespread application in more fields.

8. Conclusion

To sum up, bis(dimethylaminoethyl)ether (BDMAEE) as an efficient foaming catalyst plays an important role in the fireproof isolation technology of battery packs in new energy vehicles. Through reasonable application, it can significantly improve the safety and reliability of battery packs and provide strong support for the sustainable development of the new energy vehicle industry.

Biodegradation promotion technology for bis(dimethylaminopropyl)isopropylamine for environmentally friendly packaging materials

3月 20th, 2025 News

Bi(dimethylaminopropyl)isopropylamine biodegradation promotion technology and its application in environmentally friendly packaging materials

1. Introduction: From the Plastic Crisis to the Green Revolution

In the past few decades, plastic products have become an integral part of our lives. However, behind this convenience is a huge environmental problem – plastic pollution. According to statistics, more than 400 million tons of plastic produced worldwide each year, less than 10% of which are recycled, and most of the rest eventually enter landfills or natural environments [[1]]. These plastics take hundreds of years to completely break down, posing a serious threat to the ecosystem. Microplastics in the ocean have become the focus of scientists. They not only affect the survival of aquatic organisms, but also gradually endanger human health through the food chain.

Faced with this severe situation, governments and enterprises in various countries have turned their attention to the research and development and application of biodegradable materials. As an important part of the new environmentally friendly packaging materials, bis(dimethylaminopropyl)isopropanolamine (DIPA-BAP) has shown unique advantages in promoting the biodegradation of materials as a functional additive. This article will discuss DIPA-BAP biodegradation promotion technology, including its chemical characteristics, mechanism of action, practical application and future development direction, and conduct in-depth analysis based on relevant domestic and foreign literature.

2. Basic characteristics of bis(dimethylaminopropyl)isopropanolamine

(I) Chemical structure and properties

Bis(dimethylaminopropyl)isopropanolamine is an organic compound with the molecular formula C8H21N3O and its relative molecular mass is about 179.27[[2]]. Its molecular structure is made up of two dimethylaminopropyl groups bridged by isopropanolamine, giving it unique physical and chemical properties:

  • Solubility: DIPA-BAP is easily soluble in water and other polar solvents, which allows it to be evenly dispersed in the polymer matrix.
  • Reactive activity: Because it contains multiple amino functional groups, DIPA-BAP shows strong basicity and high reactivity, and can participate in various chemical reactions.
  • Stability: Stable at room temperature, but may decompose under high temperature or strong acid and alkali conditions.
parameter name Value/Description
Molecular formula C8H21N3O
Relative Molecular Mass About 179.27
Boiling point >250°C
Density About 0.9 g/cm³
Water-soluble Easy to dissolve

(Bi) Preparation method

The synthesis of DIPA-BAP is usually done in two steps [[3]]:

  1. Step 1: Use epoxychlorohydrin and 2 as raw materials to form an intermediate – dimethylaminopropyl chloride.
  2. Second Step: React the above intermediate with isopropanolamine to obtain the target product DIPA-BAP.

This process is simple and efficient, with fewer by-products, and is suitable for industrial production.

III. Mechanism of action of DIPA-BAP in promoting biodegradation

(I) Enhance the ability of microbial degradation

The core function of DIPA-BAP is to accelerate the biodegradation process of packaging materials. Specifically, it works in the following ways:

  1. Improve the surface characteristics of the material
    DIPA-BAP can form a hydrophilic coating on the surface of the polymer, increasing the possibility of microbial adhesion. For example, studies have found that polylactic acid (PLA) films with DIPA-BAP added are more susceptible to fungi in the soil than unmodified PLA [[4]].

  2. Providing nutritional sources
    DIPA-BAP itself is rich in nitrogen elements, which can serve as nutrients required for microorganisms to grow and reproduce, thereby indirectly accelerating the degradation rate.

  3. Regulate pH
    During the degradation process, certain microorganisms secrete acidic metabolites, resulting in a drop in the local environmental pH. DIPA-BAP has a certain buffering capacity, can maintain an appropriate pH range, and ensure that microbial activity is not inhibited.

(II) Synergistic effect with other additives

In addition to being used alone, DIPA-BAP can also be used in combination with other biodegradation promoters (such as natural polymers such as starch and cellulose) to produce stronger effects. For example, one study showed that when DIPA-BAP and tapioca starch were mixed in proportion and added to a polyethylene (PE) substrate, the degradation time of the material was shortenedAbout 60%[[5]].

Addant Type Single effect Synergy Effect
DIPA-BAP Improve microbial adhesion Enhance the overall degradation efficiency
Starry Increase material brittleness Improving Mechanical Properties
Cellulose Providing additional carbon sources Reduce energy consumption during degradation

IV. Practical application of DIPA-BAP in environmentally friendly packaging materials

As consumers’ environmental awareness increases, more and more companies are beginning to adopt sustainable packaging solutions. DIPA-BAP has been widely used in the following fields due to its excellent performance:

(I) Food Packaging

Food packaging is one of the main uses of plastic products and an important source of environmental pollution. By adding an appropriate amount of DIPA-BAP to the degradable plastics (such as PLA, PBAT), the biodegradation rate can be significantly improved while maintaining good mechanical strength and barrier properties. For example, an internationally renowned beverage brand introduced composite materials containing DIPA-BAP into its disposable cups, and the results showed that these cups could completely decompose under industrial compost conditions in just 45 days [[6]].

(II) Agricultural Plain Film

Although traditional polyethylene plastic film helps increase crop yields, the problem of difficulty in degradation has always plagued agricultural production. In recent years, researchers have developed a DIPA-BAP-based formula for degradable mulching not only quickly decomposes after the harvest season, but also replenishes the soil with organic matter [[7]]. Experimental data show that compared with ordinary plastic film, the service life of this new material is increased by 20%, while the residual amount is reduced by more than 80%.

(III) Express logistics packaging

With the rapid development of the e-commerce industry, the amount of waste generated by express logistics packaging has increased sharply. To address this challenge, some logistics companies have tried to replace traditional polystyrene foam with DIPA-BAP. Practice has proven that this new packaging not only has excellent buffer protection function, but also can quickly return to nature after being abandoned [[8]].

5. Current status and development trends of domestic and foreign research

(I) Progress in foreign research

European and American countries in biodegradable materialsThe material field started early and accumulated rich experience. For example, the Fraunhofer Institute in Germany has developed a technology platform called “BioBoost” specifically for optimizing the application effect of DIPA-BAP-like additives [[9]]. In addition, DuPont, the United States, launched a high-performance biodegradable resin, which contains DIPA-BAP as a key ingredient.

(II) Domestic research trends

In recent years, my country has also actively deployed the environmentally friendly packaging materials industry. The team of the Department of Chemical Engineering of Tsinghua University successfully improved its thermal stability and compatibility through improving the molecular structure of DIPA-BAP [[10]]. At the same time, the Ningbo Institute of Materials, Chinese Academy of Sciences focused on studying the migration behavior of DIPA-BAP in different types of polymers, providing theoretical support for the precise regulation of the degradation process.

(III) Future development direction

Although DIPA-BAP has shown great potential, its development still faces some challenges:

  1. Cost Issues
    Currently, DIPA-BAP has high production costs, which limits its large-scale promotion. Therefore, how to reduce manufacturing costs will be one of the key directions of future research.

  2. Standardization Construction
    With the growth of market demand, it is particularly important to establish unified product standards. This will help regulate market order and ensure product quality.

  3. Multifunctional design
    Combining emerging fields such as nanotechnology and intelligent responsive materials, developing DIPA-BAP matrix composite materials with multiple functions will be the key to promoting industry progress.

VI. Conclusion: From burden to resources

Plastic pollution was once seen as a heavy burden on the planet, but with innovative technologies like DIPA-BAP, we are gradually transforming it into a valuable natural resource. As an old saying goes, “Garbage is just the wealth of the wrong place.” I believe that in the near future, with the advancement of science and technology and the joint efforts of all sectors of society, environmentally friendly packaging materials will surely become an important bridge to achieve harmonious coexistence between man and nature.

Low VOC bis(dimethylaminopropyl) isopropylamine odor control scheme for automotive interior

3月 20th, 2025 News

Automatic interior low VOC bis(dimethylaminopropyl) isopropylamine odor control scheme

1. Preface: The air quality in the car is an invisible “battle”

In recent years, with the rapid development of the automobile industry and consumers’ pursuit of healthy living quality, “in-car air quality” has gradually become an important consideration in car purchase decisions. Just imagine if the pungent smell that hits you when you get into a brand new car makes you feel uncomfortable? This is the volatile organic compounds (VOCs) in the car. These chemicals not only affect the driving experience, but long-term exposure may also cause potential harm to physical health. Therefore, how to effectively control VOC emissions in automotive interiors has become an important issue that the global automotive industry needs to solve urgently.

In this “odor battle”, bis(dimethylaminopropyl)isopropanolamine (DMAIPA for short) stands out as an efficient and environmentally friendly odor control agent. It significantly reduces the odor and VOC concentration in the car by chemical reaction with harmful gas molecules. This article will start from the basic characteristics of DMAIPA and deeply explore its application principles in automotive interior odor control, and combine domestic and foreign research literature to provide readers with a detailed technical guide. At the same time, we will also make the content in this professional field vivid, interesting and easy to understand with easy-to-understand language and humorous expressions.

Next, let us walk into this scientific exploration of “fresh air” together!

2. Basic characteristics of bis(dimethylaminopropyl)isopropanolamine

(I) What is bis(dimethylaminopropyl)isopropylamine?

Bis(dimethylaminopropyl)isopropanolamine (DMAIPA), is an amine compound with a unique chemical structure. Its molecular formula is C12H30N4O2 and its molecular weight is 286.4 g/mol. DMAIPA has been widely used in many industrial fields due to its excellent chemical activity and stability, especially in the odor control of automotive interior materials.

DMAIPA’s chemical structure contains two dimethylaminopropyl side chains and one isopropanolamine group. This special structure gives it strong hygroscopicity and strong interaction ability with acid gas molecules, allowing it to effectively capture and neutralize harmful gases common in the vehicle, such as formaldehyde, acetaldehyde and other aldehydes.

  4. Environmentally friendly materials
    Compared with traditional odor control agents, DMAIPA has lower toxicity and is in line with the development trend of modern green chemical industry.

3. Source of VOC in car interior and its hazards

(I) Definition and classification of VOC

Volatile organic compounds (VOCs) refer to organic chemicals that are prone to volatile at room temperature. According to different chemical properties, VOCs can be divided into the following categories:

  1. aldehyde: such as formaldehyde, acetaldehyde, propionaldehyde, etc., mainly derived from adhesives, coatings, etc.
  2. Benzene: such as benzene, second-class, commonly found in solvent-based paints and detergents.
  3. Esters: such as ethyl esters, butyl esters, etc., are widely present in plastic products and sealants.
  4. ketones: such as methyl isobutyl ketones, etc., are more common in cleaning agents and binders.

(II) The main sources of VOC in the car

  1. Interior Materials

    • Plastic parts: Plastic components such as instrument panels, door panels, seat skeletons will release a large amount of VOC.
    • Leather and Fabric: The dyes and finishing agents used in the production process of leather seats, carpets, ceilings and other materials will also become the source of VOC.
    • Adhesive: The glue used to fix interior parts is often a major contributor to VOC emissions.

  2. External pollution
    External environmental pollutants such as roadside exhaust gas and industrial waste gas may also enter the vehicle through the air conditioning system, further aggravating the VOC problem.

(III) Potential harm of VOC to human health

Long-term exposure to high concentrations of VOC environments can cause the following health problems:

  • Respiratory tract irritation: causes symptoms such as coughing, sore throat.
  • Asensitivity reaction: induces allergic symptoms such as itching, redness and swelling of the skin.
  • Central nervous system damage: leads to headaches, inattention and even memory loss.
  • Carcogenic risk: Certain VOCs (such as benzene, formaldehyde) have been proven to be carcinogenic.

It can be seen that controlling VOC emissions in the car is not only a need to improve driving comfort, but also a necessary measure to ensure passenger health.

IV. The application principle of DMAIPA in automotive interior odor control

(I) Chemical reaction mechanism

DMAIPA achieves effective capture and neutralization of VOC molecules in the vehicle by chemical reaction. The following are diagrams of several typical reactions:

  1. Reaction with formaldehyde
    The amine groups in DMAIPA can react with formaldehyde to add up to form a stable six-membered ring product, thereby completely eliminating the toxicity of formaldehyde.

    Chemical equation:
    HCHO + NH?R ? RHNCH?OH

  2. Reaction with acetaldehyde
    Similarly, DMAIPA can also react similarly with acetaldehyde to produce corresponding addition products.

  3. Reaction with other acid gases
    The alkaline amine groups of DMAIPA can also neutralize acid gases (such as sulfur dioxide and nitrogen oxides) to further purify the air in the vehicle.

(II) Practical application scenarios

  1. Spraying treatment
    Spray the DMAIPA solution evenly on the surface of the car interior, such as seats, carpets, ceilings, etc., to form a protective film to continuously adsorb and neutralize VOC.

  2. Immersion treatment
    For textiles or leather materials, DMAIPA can be introduced into it by impregnation to provide long-term odor control function.

  3. Mixed Add
    DMAIPA is directly mixed into plastic particles or adhesives as additives during the production process, fundamentally reducing the release of VOC.

5. Current status and technological progress at home and abroad

(I) Foreign research trends

  1. US EPA Standard
    The U.S. Environmental Protection Agency (EPA) has set strict standards for air quality in cars, requiring that the VOC concentration in new cars should not exceed certain limits. Research shows that DMAIPA has performed outstandingly in meeting this standard.

  2. European CEC Code
    The European Automobile Manufacturers Association (CEC) has formulated a series of test methods and evaluation systems for in-vehicle air quality, which has promoted the widespread application of DMAIPA in high-end models.

(II) Domestic research progress

In recent years, my country has achieved remarkable results in the field of automotive interior odor control. For example, a research team at Tsinghua University developed a composite odor control agent based on DMAIPA, which has an effect of more than 30% higher than a single component. In addition, some companies have also launched independently developed DMAIPA products, gradually replacing imported raw materials and reducing production costs.
