Abstract

The invention discloses a preparation method for a high-temperature-resistant rubber material of an automobile radiating pipeline. The method comprises a formula and a preparation process. In the method, an ethylene propylene diene monomer and chlorosulfonated polyethylene rubber are used together, dicumyl peroxide and a vulcanized system of N,N-m-phenylene bismaleimide are added into the formula, a 2,2,4-trimethyl-1,2-dihydroquinoline polymer and an anti-aging agent of 2-mercaptobenzimidazole are added into the formula, and magnesium oxide is added into the formula, so that the heat resistance of the material is improved; a technical scheme of a corresponding preparation process is matched for use, so that the defects of poor high temperature resistance and difficulty in meeting the increasing requirement of the automobile industry on the heat resistance of a rubber product existing in the prior art are overcome; and a rubber material which is resistant to the high temperature of 175 DEG C is prepared, so that the heat resistance of a prepared rubber product of the automobile radiating pipeline is improved, the increasing requirement of the automobile industry on the heat resistance of the rubber product is met, and the aim of meeting a high temperature resistance standard is fulfilled.

Description

technical field [0001] The invention relates to a method for preparing a rubber material, in particular to a method for preparing a rubber product for automobile heat dissipation pipes, and a high temperature resistant rubber material for automobile heat dissipation pipes with a high temperature resistance of 175°C. Background technique [0002] Rubber products such as automotive cooling pipes made of rubber materials in the prior art have low heat resistance and cannot meet the high temperature standard of 175°C; [0003] The test data of the automobile cooling pipe rubber product made by the EPDM material of the prior art is as follows: [0004] standard specification [0005] [0006] Conclusion: Conclusion: 2.1 Change in hardness, 2.2 Change in tensile strength, and 2.3 Change in elongation at break in the second heat-resistant air aging project are unqualified; [0007] Therefore, the prior art has the problems and deficiencies of low high temperature resistance an...
