AI Technical Summary
Existing engine sealing materials cannot simultaneously meet the requirements of media resistance, high temperature resistance, and high elasticity in high temperature and oil contamination environments. Traditional materials such as NBR, HNBR, and FKM each have their own limitations, making it difficult to meet the performance requirements of engine seals while keeping costs under control.
A combination of thermoplastic polyester elastomer, hydrogenated nitrile rubber, nano-modified montmorillonite, maleic anhydride-grafted TPEE compatibilizer, vulcanizing agent, and other additives is used to prepare a medium-resistant and highly elastic rubber material through a dynamic vulcanization process, forming an interpenetrating network structure to improve the material's oil resistance, high temperature resistance, and elasticity.
The material maintains good sealing performance in high-temperature and complex media environments, extending its service life, reducing production costs, and improving production efficiency.
