Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a flame-retardant and aging-resistant sealing ring rubber material. Background technique [0002] The sealing ring is a commonly used sealing element in automobiles, mainly used for static sealing and reciprocating motion sealing. The commonly used seals in automotive fuel pumps are sealing rings. The sealing rings have good sealing performance and a wide range of applications, so they are used more and more in the design of automobiles. The choice of sealing ring material is of great significance to its sealing performance and service life, and the performance of the material directly affects the performance of the sealing ring. The material of the sealing ring in the prior art usually has the defects of low flame retardancy and easy aging, which seriously affects the service life of the sealing ring. Contents of the invention [0003] Based on the problems in the b...
