Abstract

The invention relates to a heat-resistant acrylic ester rubber which is made by copolymerization of methyl acrylate, ethyl acrylate, vinyl monochloroacetate and regulating agent. Calculating by mass percentage, the detailed mixture ratio is: methyl acrylate, 5-40%; ethyl acrylate, 50-94%; vinyl monochloroacetate, 1-10%; and regulating agent, 0.0001-1%; batch process emulsion polymerization technique is used in the process of synthesis; the initiation temperature in the process of polymerization is 10-50 DEG C and the condensation temperature is 40-70 DEG C. The invention has very excellent physical and mechanical properties and post-processing property, thus meeting requirements of the motorcycles and oil-resistant and heat-resistant rubber tubes on material, the formed product of the invention has the advantages of excellent heat-resistance and oil resistance and high tensile-strength, the application of the product ranges from leakproof material of motorcycles, oil-resistant and heat-resistant tubes to protecting jackets and the like.

Description

technical field

[0001] The invention relates to a heat-resistant acrylate rubber. Background technique

[0002] Domestic acrylate rubber is an elastomer formed by emulsion polymerization with ethyl acrylate, butyl acrylate, etc. as the main monomer, and vinyl chloroacetate as the vulcanization point monomer. Since its main chain is saturated [Cβ€” C] structure, so it has heat resistance, oil resistance, oxidation resistance and other characteristics, especially the heat resistance temperature can reach 200 Β° C, so its heat resistance level is second only to fluororubber silicone rubber. And because of its good durability against engine oil, gear oil, transformer oil, etc., it is widely used in various seals, gaskets, and hoses mainly in the fields of automobiles, motorcycles, and transformers.

[0003] At present, domestic acrylic rubber is mainly cold-resistant and widely used. The heat-resistant type is made of ethyl acrylate, acrylonitrile, etc. as the main monomers. The ...
