Thermal-sensitive catalyst SA-102: Enhance the compressive strength of polyurethane foam

Introduction

Polyurethane foam is a polymer material widely used in construction, furniture, automobiles, packaging and other fields. Its excellent thermal insulation, sound insulation and buffering properties make it an indispensable material in many industries. However, the compressive strength of polyurethane foam is one of the key indicators of its performance, which directly affects the durability and application range of the material. In order to improve the compressive strength of polyurethane foam, the thermal catalyst SA-102 came into being. This article will introduce in detail the characteristics, mechanism of action, application methods of SA-102 and its effect on improving the compressive strength of polyurethane foam.

1. Overview of thermal-sensitive catalyst SA-102

1.1 What is thermal-sensitive catalyst SA-102?

Thermal-sensitive catalyst SA-102 is a highly efficient catalyst designed specifically for the production of polyurethane foams. It can be activated within a specific temperature range, promoting polyurethane reaction, thereby optimizing the structure and performance of the foam. The main feature of SA-102 is its thermal sensitivity, that is, its activity is low at low temperatures, and its activity is significantly enhanced at high temperatures. This characteristic allows SA-102 to accurately control the reaction rate during the production of polyurethane foam, avoiding premature or late reactions, thereby improving the quality of the foam.

1.2 Main ingredients of SA-102

The main components of SA-102 include organotin compounds and amine compounds. These components play a synergistic catalytic role in the polyurethane reaction, which can effectively promote the reaction between isocyanate and polyol, and form a stable polyurethane structure.

Ingredients	Content (%)	Function
Organotin compounds	30-40	Promote the reaction between isocyanate and polyol
Amine compounds	20-30	Adjust the reaction rate and improve the stability of the foam structure
Solvent	30-40	Dissolve and disperse catalyst components

1.3 Physical and chemical properties of SA-102

Properties	Value/Description
Appearance	Colorless to light yellow liquid
Density	1.05-1.10 g/cm³
Viscosity	50-100 mPa·s
Flashpoint	>100°C
Solution	Easy soluble in organic solvents, insoluble in water
Storage Conditions	Cool and dry places to avoid direct sunlight

2. The mechanism of action of SA-102

2.1 Thermal sensitivity catalysis

The thermal sensitivity of SA-102 is one of its significant features. At low temperatures, SA-102 has lower activity and slow reaction rates, which helps control the reaction in the early stages of foam formation and avoid premature gelation. As the temperature increases, the activity of SA-102 gradually increases, the reaction rate accelerates, and promotes the rapid molding and curing of the foam. This temperature-dependent catalytic action allows SA-102 to achieve precise reaction control during the production of polyurethane foam, thereby optimizing the foam’s structure and performance.

2.2 Promote the reaction between isocyanate and polyol

The organotin compounds and amine compounds in SA-102 can effectively promote the reaction between isocyanate and polyol. Organotin compounds mainly catalyze the addition reaction between isocyanates and polyols to form carbamate bonds; while amine compounds attack the isocyanates through nucleophilic attacks, forming urea bonds. These two reactions work together to form a stable polyurethane structure and enhance the mechanical properties of the foam.

2.3 Optimize foam structure

The catalytic action of SA-102 can not only promote the reaction, but also optimize the structure of the foam. By precisely controlling the reaction rate, SA-102 can avoid premature bursting or excessive expansion of bubbles in the foam, thereby forming a uniform and fine cell structure. This structure not only improves the compressive strength of the foam, but also improves its thermal and sound insulation properties.

III. Application of SA-102 in the production of polyurethane foam

3.1 Application method

SA-102 is usually added in liquid form to the formulation of polyurethane foam. The amount of addition is adjusted according to the specific formula and production process, generally between 0.1-0.5%. The following are typical application steps for SA-102:

Mix: Foam the polyol and foamMix the raw materials such as agents and stabilizers evenly.
Add SA-102: Add SA-102 to the mixed raw materials and stir well.
Reaction: Pour the mixed raw materials into the mold and perform foaming and curing reactions.
Post-treatment: Cut, trim and other post-treatment.

The following is a typical formula for producing polyurethane foam using SA-102:

Raw Materials	Doing (parts)	Function
Polyol	100	Main reactants, forming polyurethane structure
Isocyanate	50	Main reactants, forming polyurethane structure
Frothing agent	2	Create bubbles and form foam structure
Stabilizer	1	Stable the foam structure and prevent bubble bursting
SA-102	0.3	Catalyzer, promote reactions, optimize foam structure

3.3 Application Effect

Polyurethane foam produced using SA-102 has the following advantages:

Enhanced compressive strength: SA-102 can optimize the foam structure and improve compressive strength.
Every uniform cell: SA-102 can form a uniform and fine cell structure to enhance the mechanical properties of the foam.
Precise reaction control: The thermal sensitivity of SA-102 makes the reaction rate controllable, avoiding premature or too late reactions.

IV. The effect of SA-102 on the compressive strength of polyurethane foam

4.1 Definition of compressive strength

Compressive strength refers to the ability of a material to resist deformation when subjected to compression force. For polyurethane foam, compressive strength is one of its important mechanical properties indicators, which directly affects the durability of the materialSex and scope of application.

4.2 SA-102 enhancement mechanism against compressive strength

SA-102 enhances the compressive strength of polyurethane foam through the following mechanism:

Optimize the cell structure: SA-102 can form a uniform and fine cell structure, reduce defects in the foam and improve compressive strength.
Enhanced Molecular Chain Crosslinking: SA-102 can promote the reaction between isocyanate and polyol, form more urethane and urea bonds, enhance the crosslinking of molecular chains, and enhance compressive strength.
Control reaction rate: The thermal sensitivity of SA-102 makes the reaction rate controllable, avoiding premature or late reactions, thereby optimizing the foam structure and improving compressive strength.

4.3 Experimental data

The following is a comparison data on compressive strength of a set of polyurethane foams produced using SA-102 and without SA-102:

Sample	Compressive Strength (kPa)
Not using SA-102	150
Using SA-102	200

As can be seen from the table, the compressive strength of polyurethane foam produced using SA-102 is significantly higher than that of foams not using SA-102.
