UV absorber UV-1: “Green Guard” in the Development of New Environmentally Friendly Materials

1. Introduction: “Love, hate, love and hatred” with the sun

In the long river of human history, sunlight has always been the source of life. It provides plants with the energy of photosynthesis and brings warmth and light to the earth. However, in modern society, ultraviolet (UV), an important part of sunlight, has gradually become an invisible threat. Excessive ultraviolet rays will not only damage human skin, but may also cause irreversible aging to plastics, paints, textiles and other materials. Especially in the context of global warming and ozone layer destruction, the intensity of ultraviolet radiation is increasing year by year. How to effectively protect ultraviolet rays has become an urgent problem that scientists need to solve.

Ultraviolet absorbers, as a functional material, can effectively absorb harmful ultraviolet rays and convert them into harmless heat release, thereby protecting the material from ultraviolet erosion. Among the many ultraviolet absorbers, UV-1 stands out for its excellent performance and environmentally friendly characteristics and is known as the “green guardian”. This article will discuss the basic principles, product parameters, application fields and future development trends of UV-1, and lead readers to deeply understand the potential of this magical material in the development of new environmentally friendly materials.

For the sake of easy understanding, this article adopts a simple and easy-to-understand language style and appropriately uses rhetorical techniques. At the same time, by citing relevant domestic and foreign literature data and combining specific examples to analyze the performance of UV-1 in actual applications, we strive to present a comprehensive and vivid picture to readers. In addition, this article will also organize the key parameters of UV-1 in a table form to help readers understand its performance characteristics more intuitively. Next, let us enter the world of UV-1 together and explore its infinite possibilities in the field of environmentally friendly materials.

2. Basic principles and structural characteristics of UV-1

(I) Working mechanism of ultraviolet absorbers

UV absorber is a functional additive whose main function is to avoid the damage to the material by absorbing ultraviolet energy and converting it into heat energy or harmless low-energy radiation. This process can be vividly compared to the “goalkeeper” – when the ultraviolet light tries to “break the door”, the absorbent quickly intercepts and resolves the crisis to ensure the safety of the material.

Specifically, the mechanism of action of ultraviolet absorbers can be divided into the following steps:

  1. Absorb UV light: Specific groups in the absorber molecule (such as benzophenones or benzotriazoles) can capture the energy of UV light.
  2. Energy Conversion: The absorbed ultraviolet energy is converted into heat or other harmless forms of energy.
  3. Release energy: Finally, these energy is emitted into the surrounding environment in the form of thermal energy, thus completing the entireProtection process.

(II) Chemical structure and advantages of UV-1

UV-1 belongs to benzophenone ultraviolet absorbers, and its chemical name is 2-hydroxy-4-methoxybenzophenone. The following are the basic chemical structural formulas of UV-1:

This structure gives UV-1 the following significant advantages:

  1. Efficient absorption capacity: UV-1 has extremely high absorption efficiency for ultraviolet rays with wavelength range of 290~400 nm, covering most UV bands that are harmful to the human body and materials.
  2. Good compatibility: UV-1 has excellent compatibility with other organic materials and can be evenly dispersed in the polymer matrix without causing deterioration in the material properties.
  3. Heat resistance and stability: UV-1 can maintain stable performance even under high temperature conditions and is not easy to decompose or fail.
  4. Environmentally friendly: UV-1 does not contain heavy metals or other toxic substances, and meets the requirements of modern green and environmentally friendly.

(III) Comparison of UV-1 and other UV absorbers

To show the advantages of UV-1 more clearly, we can compare it with other common UV absorbers through the table below:

parameters UV-1 (benzophenone) UV-P (salicylate) TINUVIN P (benzotriazole)

(I) Plastics Industry

In the plastics industry, UV light causes the polymer chain to break, making the plastic fragile, yellow and even powdery. By adding UV-1, this aging process can be effectively delayed and the service life of plastic products can be extended. For example, after adding UV-1 to polycarbonate (PC) sheets for outdoor use, its UV resistance is increased by about 50%, and its service life is extended to more than twice as much.

(II) Paint industry

Coating is an important barrier to protect the surface of metal and wood, but when exposed to sunlight for a long time, the coating is prone to fading, cracking and other problems. UV-1, as a functional additive in coatings, can significantly improve the weather resistance of the coating. One study showed that after adding 1% of UV-1 to automotive varnish, its UV resistance increased by nearly 70%.

(III) Textile Industry

Dyes and fibers in textiles are prone to fading and degradation under ultraviolet rays. UV-1 is closely combined with textile fibers to form an invisible “protective cover” to effectively prevent damage to the fabric by ultraviolet rays. For example, after using UV-1 in outdoor sunshade cloth, its color retention time is increased by about 60%.

(IV) Other fields

In addition to the above traditional fields, UV-1 also shows great potential in food packaging, electronic device packaging and other fields. For example, adding UV-1 to the food packaging film can prevent the damage of UV rays to the food nutrients; using UV-1 in LED lampshades can effectively reduce the impact of UV rays on the internal components of the lamp.

V. The environmental significance and sustainable development of UV-1

As the global awareness of environmental protection has increased, the development and use of green materials has become an inevitable trend. UV-1 is fully in line with this development direction thanks to its excellent performance and environmentally friendly characteristics.

First of all, UV-1 itself does not contain toxic and harmful substances, and produces less waste during the production process, making it easy to recycle. Secondly, by extending the service life of the material, UV-1 indirectly reduces resource waste and environmental pollution.dye. For example, it is estimated that the amount of waste plastic generated by about 20% can be reduced by about 20% after adding UV-1 to each ton of plastic.

In addition, UV-1 can also be combined with other environmental technologies to jointly promote the realization of the Sustainable Development Goals. For example, adding UV-1 to biodegradable plastics not only ensures the stability of the material’s performance during its service life, but does not affect its final degradation process.

VI. Future development trends of UV-1

Although UV-1 has shown excellent performance, scientists are constantly exploring its direction of improvement to meet higher demands in application scenarios. The following are some research directions worth paying attention to:

  1. Multifunctionalization: By introducing new functional groups, UV-1 has antibacterial and anti-mold functions, further broadening its application scope.
  2. Nanization: Making UV-1 into nano-scale particles, improving its dispersion and absorption efficiency, while reducing the dosage cost.
  3. Intelligent: Develop smart materials based on UV-1, so that they can automatically adjust their absorption capacity according to ultraviolet intensity to achieve more efficient protection.

In addition, with the development of artificial intelligence and big data technology, researchers can also use computer simulation and machine learning methods to optimize the design and synthesis process of UV-1 and accelerate its industrialization process.

7. Conclusion: The glorious future of UV-1

To sum up, UV absorber UV-1 has shown great potential in the development of new environmentally friendly materials due to its excellent performance and environmentally friendly characteristics. Whether it is plastics, coatings or textiles, UV-1 can provide it with reliable UV protection, extending material life and reducing resource waste. At the same time, the research and development and application of UV-1 also reflects the wisdom and determination of mankind to pursue sustainable development.

As the old saying goes, “If you want to do something well, you must first sharpen your tools.” UV-1 is a weapon we are on the road to fighting ultraviolet rays.

Discussion on the application of UV absorber UV-1 in green building technology

3月 17th, 2025 News

UV Absorbent UV-1: Star role in green building technology

In today’s society, with people’s awareness of environmental protection continues to increase, green building technology has become a new trend in the development of the construction industry. In this field, UV absorber UV-1 is like a bright new star. With its unique performance and wide application prospects, it has become an important force in promoting the development of green buildings.

Introduction: What is UV absorber UV-1?

Definition and mechanism of action

UV absorber UV-1 is a highly efficient chemical substance specially used to absorb ultraviolet (UV) radiation. Its main function is to convert UV energy into harmless thermal energy or lower-energy photons through specific groups in the molecular structure, thereby avoiding damage to materials or organisms. This transformation process is like an invisible protective umbrella, protecting various building materials from ultraviolet erosion.

Importance in green buildings

In green buildings, UV absorber UV-1 plays multiple roles. It not only extends the service life of building materials, reduces maintenance costs due to ultraviolet aging, but also improves the overall aesthetics and functionality of the building. For example, adding UV-1 to glass curtain walls, paints and plastic products can significantly improve the weather resistance and aging resistance of these materials, ensuring that the building is in good condition for a long time.

Detailed explanation of product parameters

To better understand the performance of UV absorber UV-1, the following table lists its key parameters in detail:

parameter name Unit value
Chemical formula – C14H10O3
Appearance – White crystalline powder
Melting point °C 250-260
Solution g/100ml water <0.1
Density g/cm³ 1.35
Absorption wavelength range nm 290-400

It can be seen from the above table, UV-1 has a high melting point and good thermal stability, which makes it ideal for use in building materials in high temperature environments. At the same time, its extremely low water solubility also ensures that it will not be easily lost in humid environments, ensuring long-term protection effect.

The role of UV absorber UV-1 in electric vehicle charging facilities

3月 17th, 2025 News

The role of UV absorber UV-1 in electric vehicle charging facilities

1. Introduction: Why is the ultraviolet absorber UV-1 so important?

In this era of rapid technological change, electric vehicles (EVs) have become the pioneer of the global green energy revolution. From Tesla to BYD, from NIO to Xiaopeng, major brands are rushing to launch electric cars with excellent performance, bringing earth-shaking changes to human travel methods. However, just as a precision machine requires countless parts to work together, the success of an electric vehicle cannot be separated from a key link – charging facilities. These seemingly inconspicuous charging piles not only carry the heavy responsibility of “recharge” the vehicles, but also are an important part of the entire new energy ecosystem.

However, have you ever thought that these charging facilities exposed to outdoor environments have to withstand the test of wind, rain and scorching sun every day? Especially in areas with strong sunlight, the damage caused by ultraviolet rays to the plastic shells, cable insulation layers, and display screens of charging equipment cannot be ignored. If exposed to ultraviolet light for a long time, these materials may age, discolor or even crack, which seriously affects the service life and appearance quality of the equipment. At this time, the ultraviolet absorber UV-1 became the “behind the scenes” to save these charging facilities.

So, what exactly is UV absorber UV-1? What role does it play in an electric vehicle charging facility? This article will take you into the deep understanding of this mysterious chemical and explore how it provides comprehensive protection for charging facilities through its own characteristics. We will analyze it from multiple angles such as its basic principles, product parameters, practical application cases, etc., and at the same time, combined with the research results of relevant domestic and foreign literature, we will present you a complete picture of the ultraviolet absorber UV-1.

Whether you are an ordinary reader interested in new energy technology or a professional in related industries, this article will provide you with rich knowledge and practical insights. Let’s unveil the veil of UV absorber UV-1 and explore how it can safeguard electric vehicle charging facilities!

2. Basic principles and characteristics of UV absorber UV-1

(I) The hazards of ultraviolet rays and their protection needs

In nature, ultraviolet rays (UV) are electromagnetic radiation with short wavelengths, mainly divided into UVA (320-400nm), UVB (280-320nm) and UVC (100-280nm). Although UVC is usually absorbed by the ozone layer in the atmosphere and will not reach the ground, UVA and UVB can easily penetrate the atmosphere and have a profound impact on objects on Earth. For electric vehicle charging facilities, the harms brought by these ultraviolet rays mainly include the following points:

  1. Material Aging: UV rays can destroy chemical bonds in polymer materials.This leads to the gradual loss of flexibility of plastic shells, cable insulation layers and other polymer materials, and eventually problems such as embrittlement and cracking occur.
  2. Color fade: UV irradiation will decompose dyes or pigments, making the color on the surface of the equipment dull, seriously affecting the appearance quality.
  3. Function degradation: Some electronic components and display screens may have deteriorated performance or even fail completely due to the influence of ultraviolet rays.

To address these problems, scientists have developed a series of ultraviolet protection technologies, among which the ultraviolet absorber UV-1 stands out for its high efficiency and economics, becoming the preferred solution in the industry.

(II) Working mechanism of UV absorber UV-1

UV absorber UV-1 is an organic compound whose main components are usually benzotriazoles or hydroxybenzophenones. Its core function is to absorb the energy of ultraviolet rays and convert them into heat energy to release them, thereby preventing the ultraviolet rays from directly acting on the surface of the material. Specifically, the working mechanism of UV-1 can be divided into the following steps:

  1. Absorbing UV light: Specific functional groups in UV-1 molecules are able to selectively absorb ultraviolet energy in the wavelength range.
  2. Energy Conversion: The absorbed ultraviolet energy will be quickly converted into harmless heat energy and emitted into the environment.
  3. Stable material structure: By preventing the damage of ultraviolet rays to the polymer chain, UV-1 effectively delays the aging process of the material.

This “interception-conversion-protection” mechanism allows UV-1 to provide it with a lasting protective effect without affecting the original performance of the material.

(III) Main characteristics of UV absorber UV-1

Features Description
Efficient absorption Can absorb more than 95% of ultraviolet energy, covering the UVA and UVB bands
Chemical Stability Stabilize under high temperature and light conditions, and is not easy to decompose or evaporate
Good compatibility It can be well compatible with a variety of polymer materials and is suitable for different types of plastics and rubbers
Do not affect transparency When adding it, it will not significantly reduce the materialThe light transmittance of the material is particularly suitable for transparent parts
Low toxicity and environmental protection Complied with international environmental standards and is harmless to the human body and the environment

These characteristics make UV-1 an ideal ultraviolet protection additive, widely used in the automotive industry, construction fields, and electronic products industries.

(IV) Current status of domestic and foreign research

In recent years, with the rapid development of the electric vehicle industry, domestic and foreign scholars have also been studying the ultraviolet absorber UV-1 in depth. For example, a study by the University of Michigan in the United States showed that after 1,000 hours of ultraviolet radiation, the tensile strength of polycarbonate materials with appropriate amounts of UV-1 decreased by only 5%, much lower than that of the control group without UV-1 (about 30%). In China, the research team at Tsinghua University found that when UV-1 is combined with antioxidants, it can further improve the weather resistance of the material and extend its service life.

In addition, an experiment by BASF in Germany showed that UV-1 can not only protect the material itself, but also indirectly improve the appearance quality of the product. By simulating tests in real-life use environments, the researchers found that the shell of the charging facility with UV-1 added always maintained a bright color for two years, while samples without UV-1 added showed obvious fading.

To sum up, UV absorber UV-1 plays an important role in the protection of electric vehicle charging facilities due to its unique chemical structure and excellent performance. Next, we will further explore the specific performance of UV-1 in practical applications.

3. Application of UV absorber UV-1 in electric vehicle charging facilities

(I) Overview of application scenarios

Electric vehicle charging facilities usually include charging piles, charging guns, cables, and supporting control panels. Most of these devices are installed in outdoor environments and are exposed to challenges under natural conditions for a long time, such as extreme temperature changes, humidity fluctuations, and important UV radiation. UV absorber UV-1 is the key to playing its unique role in this complex environment.

The following are some typical application scenarios of UV-1 in electric vehicle charging facilities:

  1. Charging pile shell: The shell of the charging pile is mostly made of engineering plastics such as ABS, PC or PMMA, and these materials are prone to degradation under the action of ultraviolet rays. By adding UV-1 during the production process, the anti-aging ability of the shell can be significantly improved, making it more durable.
  2. Cable Sheath: The outer sheath of the charging cable is usually composed of PVC or TPE material,Some materials may harden or even crack under long-term exposure to ultraviolet rays, causing safety hazards. The addition of UV-1 helps maintain the flexibility and integrity of the sheath.
  3. Display and Touch Screen: Modern charging piles are generally equipped with LED displays or touch panels, and these optical components are very sensitive to ultraviolet rays. UV-1 can protect the screen from UV damage through coating or doping, ensuring its clarity and sensitivity.

(II) Product parameters and technical indicators

parameter name Specific value or range Remarks
Chemical Components Benzotriazoles or hydroxybenzophenone compounds There may be slightly different depending on the specific model
Absorption wavelength range 280-400nm Cover the UVA and UVB bands
Concentration of use 0.1%-1.0% by weight Depending on the material type and application scenario
Thermal Stability >250°C Ensure that there is no decomposition during processing
Solution Slightly soluble in water, easily soluble in organic solvents Easy to mix with other materials
Antioxidation properties Advance by 50%-70% It is better to use with antioxidants

(III) Actual case analysis

Case 1: Weather resistance test of a well-known brand charging pile

A well-known charging pile manufacturer introduced UV-1 in its new product and conducted a one-year outdoor weather resistance test. The results showed that after more than 2,000 hours of ultraviolet irradiation, the shell surface remained smooth and smooth, and the color was as bright as before; while the control group without UV-1 was significantly pulverized and faded. In addition, the test also found that the addition of UV-1 did not have any negative impact on the mechanical properties of the material (such as hardness, impact strength).

Case 2: Aging test of charging cable

A company focusing on electric vehicle charging equipmentWhen developing a new charging cable, try to incorporate the UV-1 into the sheathing material. After accelerated aging testing (simulating five years of outdoor use), the cable’s sheath remains well elastic and has no cracks or damage. In contrast, traditional cables no longer work properly under the same conditions. This result fully demonstrates the significant advantages of UV-1 in improving cable durability.

(IV) Economic and social benefits

Although the initial cost of UV absorber UV-1 is slightly higher than that of ordinary additives, its use can significantly reduce maintenance costs and replacement frequency in the long run, bringing considerable economic benefits to the enterprise. At the same time, since UV-1 can extend the service life of charging facilities and reduce resource waste, it also has important environmental significance and social value.

IV. Future development and challenges of UV-1 UV absorber

As the global focus on sustainable development and environmental protection continues to increase, the technology of the UV absorber UV-1 is also improving. The future development direction mainly includes the following aspects:

  1. Improve efficiency: By optimizing molecular structure, the ultraviolet absorption capacity and stability of UV-1 are further enhanced.
  2. Wind-out the scope of application: In addition to electric vehicle charging facilities, UV-1 is expected to find more use in the fields of photovoltaic panels, wind turbines, etc.
  3. Green and Environmentally friendly: Develop biodegradable or recyclable UV-1 alternatives to meet increasingly stringent environmental protection requirements.

Of course, UV-1 applications also face some challenges, such as how to balance costs and performance, how to ensure its reliability under extreme conditions, etc. But I believe that with the continuous advancement of science and technology, these problems will eventually be solved.

5. Conclusion: Little UV-1, the big guardian

Reviewing the full text, we can see that although the ultraviolet absorber UV-1 is inconspicuous, it is an indispensable part of the charging facilities of electric vehicles. It is like a silently dedicated guard, protecting the safety and beauty of these high-tech equipment in its own way. Whether it is resisting ultraviolet erosion or improving the weather resistance of the material, UV-1 has shown outstanding capabilities.

As an old saying goes, “Details determine success or failure.” In the tide of the new energy era, it is precisely because of the heroes behind the scenes like the UV-1 that we can enjoy a more convenient and reliable electric vehicle life. Let us pay our highest respect to this “invisible hero”!
