Abstract

The invention discloses a preparation method of an automobile pipe rubber material. The invention adopts a following formula and a following preparation process. In the formula, ethylene-propylene-diene monomer rubber and oil-filled ethylene-propylene-diene monomer rubber are combined as a main raw material to improve the diesel resistance; bis(tert-butyldioxyisopropyl)benzene, N, N'-m-phenylenedimaleimide and trifunctional acrylate are combined as a vulcanizing agent to improve the heat resistance; 4, 4'-bis(a, a dimethyl benzyl)diphenylamine is used as an anti-aging agent to improve the heat resistance; high-flash point paraffin oil is used as a plasticizer to improve the heat resistance. According to the technical solution, through matching with the corresponding preparation process, automobile rubber water pipe products produced from the prepared rubber material meet requirements of TL52361 automobile water pipe standards.

Description

technical field [0001] The invention relates to a method for preparing a rubber material, in particular to a method for preparing an automobile pipeline rubber material used to manufacture automobile water pipe rubber products conforming to the TL52361 standard. Background technique [0002] With the development of the automobile industry, the standard requirements for auto parts are also constantly improving. The automobile water pipe standard TL52361-2016-11 is the latest standard, referred to as the TL 52361 standard; the rubber products of the automobile water pipe are required to have high temperature resistance, low temperature resistance, and oil resistance. Performance, and meet the requirements of the TL 52361 standard and the ELV directive; the existing technology uses EPDM materials to make rubber products for automotive water pipes, which is difficult to meet the requirements of the TL52361 standard, as follows: [0003] Standard specification for test data of ru...
