introduction

The heat resistance of rubber products is particularly important in the context of growing market demand. Improving heat resistance can not only extend the service life of products, but also open up more application markets. This article will analyze how to improve the heat resistance of rubber products through technical means.

Recipe optimization

Formula optimization is the basis for improving the heat resistance of rubber products. By adding heat-resistant agents and stabilizers, the thermal stability of rubber can be significantly improved. Data show that in standard tests, adding 2% to 5% heat-resistant agent can increase the heat-resistant temperature of rubber products by 15 to 30 degrees Celsius.

Selection of heat-resistant agents

Common heat-resistant agents include phenolic antioxidants, copper salts, and zinc salts. Choosing the right heat-resistant agent requires consideration of various factors, such as compatibility with the rubber substrate and cost-effectiveness.

Addition of stabilizer

Stabilizers such as UV absorbers and light stabilizers can effectively prevent the degradation of rubber under light and heat conditions. Research data shows that in high temperature environments, the addition of these stabilizers can significantly delay the aging rate of rubber products.

technical improvements

In addition to formula optimization, improvements in production technology and processing technology can also significantly improve the heat resistance of rubber products.

Cross-linking technology

Cross-linking reaction is one of the key technologies to improve the heat resistance of rubber products. Through high-temperature cross-linking or radiation cross-linking, a more stable molecular structure can be formed, thereby improving its heat resistance. Data show that the heat resistance of rubber products using radiation cross-linking technology has increased by more than 20%.

surface treatment

Surface treatment technologies such as fluorination and coating can effectively improve the high temperature resistance of the rubber surface and simultaneously improve its corrosion resistance. Research shows that the heat-resistant temperature of surface-treated rubber products can be increased by 10 to 20 degrees Celsius.

in conclusion

Through formula optimization and technological improvement, the heat resistance of rubber products can be significantly improved. This not only helps meet the growing market demand, but also provides technical support for enterprises to develop more application areas. In the future, with the continuous advancement of technology, the heat resistance of rubber products will be further improved, bringing more innovation and development opportunities to related industries.
