Abstract

The invention provides high-temperature-resisting acrylic rubber which is prepared from, by weight, 30-45 parts of hard monomer-methyl methacrylate, 10-15 parts of soft monomer n-butyl acrylate, 30-35 parts of functional monomers, 20-30 parts of filler, 10-15 parts of special core-shell microspheres, 2-4 parts of initiator, 1-3 parts of vulcanizing agent and 30-60 parts of solvent. The function monomers contain one or more of hydroxide radical, carboxyl, epoxy group, aryl and phosphate. Multiple ways for improving high temperature resistance are combined and matched, the acrylic rubber with the excellent high temperature resistance is obtained, and using requirements of the prior art can be met.

Description

technical field [0001] The invention relates to an acrylic rubber, in particular to a high temperature resistant acrylic rubber. Background technique [0002] Acrylate rubber is a rubber made of acrylate polymer as the main component. It has heat resistance like silicone rubber and fluororubber and oil resistance like fluororubber, epichlorohydrin rubber and nitrile rubber. It can be used in automotive parts that require heat resistance and lubricating oil resistance, such as various seals near the engine, gaskets, packings, turbine hoses, etc. [0003] Based on its excellent performance, its application fields are becoming wider and wider, and the requirements for its various properties are getting higher and higher. The requirements for high temperature resistance of acrylic rubber are also gradually increasing. fulfil requirements. Therefore, there is an urgent need for an acrylate rubber with excellent high temperature resistance to meet the needs of the prior art. C...
