Abstract

The invention discloses a method for preparing a cooling water pipe rubber material for an automobile. A formula and a preparation process are involved. Ethylene-propylene-diene monomer is adopted; a vulcanization system of sulfur, tetramethyl thiuram disulfide, and dipentamethylenethiuram tetrasulfide is adopted in the formula so as to improve the pressing deformation resistance and heat resistance of the material; poly(1,2-dihydro-2,2,4-trimethyl-quinoline) antiager is added in the formula so as to improve the heat resistance and ageing resistance of the material; filling reinforcing agents, namely sillitin powder and active calcium carbonate are added in the formula so as to improve the electrical resistance of the material; and the corresponding technical scheme of the preparation process is matched with the formula so as to overcome the defects of low heat resistance, pressing deformation resistance, and electrical resistance in the prior art, and by preparing the rubber materialwith high heat resistance, high pressing deformation resistance and high electrical resistance, the heat resistance, the pressing deformation resistance and the electrical resistance of the manufactured cooling water pipe product for the automobile are improved, and the aims of meeting increasingly high requirements of automobile industry on rubber products, and meeting the Mazda MES PA15 185A standard can be fulfilled.

Description

technical field [0001] The invention relates to a method for preparing a rubber material, in particular to a method for preparing an automobile cooling water pipe rubber material which is used for manufacturing automobile cooling water pipes and has heat resistance, pressure change resistance and resistance resistance. Background technique [0002] The rubber materials used in the prior art to make rubber products such as automobile cooling systems are heat-resistant, pressure-resistant, and have low resistance to electrical resistance, which cannot meet the requirements of Mazda MES PA15 185A standards. For example, the rubber of automobile cooling systems made of EPDM rubber The test data of the product are as follows: [0003] Standard specification Mazda MES PA15 185A [0004] Test item Test condition Test method Standard value Measured value [0005] 1. Initial state [0006] 1.1 Hardness (HA) MES MN 301 6 70±5 68 [0007] 1.2 Tensile strength (MPa) MES MN 301 4 ≥10...
