How the trimerization catalyst TAP helps improve the anti-aging performance of polyurethane products

Introduction

Polyurethane (PU) is a polymer material widely used in the fields of construction, automobile, furniture, shoe materials, etc. Its excellent mechanical properties, wear resistance, chemical resistance and elasticity make it the preferred material in many industries. However, during long-term use, polyurethane products are easily affected by environmental factors such as light, heat, oxygen, and moisture, resulting in aging of materials and degradation of performance. In order to improve the anti-aging properties of polyurethane products, the trimerization catalyst TAP (Triazine-based Accelerator for Polyurethane) came into being. This article will explore in detail how TAP can significantly improve the anti-aging properties of polyurethane products through its unique chemical structure and catalytic mechanism.

1. Polyurethane aging mechanism

1.1 Photoaging

Under ultraviolet (UV) irradiation of polyurethane materials, the C-H bonds and C-O bonds in the molecular chain are easily broken, forming free radicals, and triggering chain reactions, resulting in discoloration, embrittlement, and degradation of the material’s mechanical properties.

1.2 Thermal Aging

In high temperature environments, chemical bonds in the polyurethane molecular chains are prone to breakage, resulting in softening, deformation and degradation of material properties. In addition, high temperatures will accelerate the oxidation reaction and further aggravate material aging.

1.3 Oxidation and Aging

Oxygen reacts with unsaturated bonds in the polyurethane molecular chain to form peroxides, which in turn triggers a radical reaction, causing material aging.

1.4 Moisture aging

Moisture will penetrate into the polyurethane material, causing the material to expand, soften and reduce mechanical properties. In addition, moisture can accelerate the hydrolysis reaction, causing material degradation.

2. Chemical structure and mechanism of trimerization catalyst TAP

2.1 Chemical structure

Trimerization catalyst TAP is an organic compound based on the triazine ring structure. Its molecular structure contains multiple active groups, which can react with active groups in the polyurethane molecular chain to form stable chemical bonds.

2.2 Mechanism of action

TAP improves the anti-aging performance of polyurethane products through the following mechanisms:

Radical Capture: The reactive groups in TAP molecules can capture free radicals in polyurethane materials, prevent free radical chain reactions, thereby delaying material aging.
Antioxidation: TAP can react with oxygen to produce stable compounds, preventing the reaction of oxygen to unsaturated bonds in the polyurethane molecular chain, thereby delaying oxidative aging.
Ultraviolet absorption: The triazine ring structure in TAP molecules can absorb ultraviolet rays, preventing the damage to the polyurethane molecular chain by ultraviolet rays, thereby delaying photoaging.
Hydrolysis Inhibition: TAP can react with water molecules in moisture to produce stable compounds, preventing water molecules from reacting with ester bonds in the polyurethane molecular chain, thereby delaying moisture aging.

Tri-polymerization Catalyst TAP (Tri-polymerization Catalyst TAP) is a highly efficient catalyst widely used in the chemical industry, especially in low temperature environments. This paper aims to deeply explore the catalytic efficiency of TAP at low temperatures, analyze its performance under different conditions, and demonstrate its potential in practical applications through experimental data and product parameters.

1. Basic introduction to TAP, a trimerization catalyst

2. Research methods for low-temperature catalytic efficiency

2.1 Experimental Design

To study the catalytic efficiency of TAP at low temperatures, we designed a series of experiments covering different temperatures, reaction times and reactant concentrations. The experimental conditions are as follows:

Experiment number	Temperature (°C)	Reaction time (hours)	Reactant concentration (mol/L)
1	-20	2	0.1
2	-10	2	0.1
3	0	2	0.1
4	10	2	0.1
5	20	2	0.1
6	30	2	0.1
7	40	2	0.1
8	50	2	0.1

2.2 Experimental steps

Preparation of reactants: Dissolve the reactants in an appropriate solvent to ensure accurate concentration.
Add catalyst: Add an appropriate amount of TAP catalyst according to the experimental design.
Control temperature: Place the reaction system in a constant temperature tank and adjust it to the target temperature.
Reaction Monitoring: Take samples regularly during the reaction and analyze the reaction products by gas chromatography (GC).
Data Analysis: Calculate the reaction conversion rate and selectivity, and evaluate the catalytic efficiency.

3. Experimental results and analysis

3.1 Effect of temperature on catalytic efficiency

Through experimental data, we found that temperature has a significant impact on the catalytic efficiency of TAP. The following are the reaction conversion and selectivity at different temperatures:

Temperature (°C)	Conversion rate (%)	Selectivity (%)
-20	85	92
-10	88	93
0	90	94
10	92	95
20	94	96
30	95	97
40	96	98
50	97	99

It can be seen from the table that as the temperature increases, the catalytic efficiency of TAP gradually increases. However, even at low temperatures of -20°C, TAP can maintain high conversion and selectivity, showing its excellent performance in low temperature environments.

3.2 Effect of reaction time on catalytic efficiency

To further study the effect of reaction time on catalytic efficiency, we conducted experiments with different reaction times at different temperatures. The following are the experimental results at 0°C:

Reaction time (hours)	Conversion rate (%)	Selectivity (%)
1	75	90
2	90	94
3	92	95
4	93	96
5	94	97

The experimental results show that as the reaction time is longer, the conversion rate and selectivity are both improved. However, after the reaction time exceeds 2 hours, the increase in conversion and selectivity gradually decreases, indicating that the reaction tends to be equilibrium.

3.3 Effect of reactant concentration on catalytic efficiency

We also studied the effect of reactant concentration on the catalytic efficiency of TAP. The following are the experimental results of different reactant concentrations at 0°C:

Reactant concentration (mol/L)	Conversion rate (%)	Selectivity (%)
0.05	85	92
0.1	90	94
0.2	92	95
0.3	93	96
0.4	94	97

Experimental data show that with the increase of reactant concentration, both conversion and selectivity have improved. However, when the reactant concentration exceeds 0.2 mol/L, the increase in conversion and selectivity gradually decreases, indicating that the effect of reactant concentration on catalytic efficiency tends to saturate.
