Abstract

The invention belongs to the field of cable material preparation, and relates to an oil-resistant and solvent-resistant rubber composite material, a preparation method thereof and application of the oil-resistant and solvent-resistant rubber composite material in cables. According to the oil-resistant solvent-resistant rubber composite material disclosed by the invention, the nitrile rubber, the activated nano silica and the barium sulfate powder are added on the basis of the terpolymer epichlorohydrin rubber, so that good physical properties are ensured, and meanwhile, the oil-resistant solvent-resistant performance of the rubber composite material is greatly improved; the rubber composite material has oil resistance, solvent resistance and good processability, and the solvent resistance of the rubber composite material is further improved by using 2, 4, 6-trithiol thiotriazine as the vulcanizing agent.

Description

technical field [0001] The invention belongs to the field of cable material preparation, and relates to an oil-resistant and solvent-resistant rubber composite material, a preparation method thereof, and an application in cables. Background technique [0002] JEM is a kind of motor lead wire, which meets the requirements of JB / T 6213-2006 standard. Its aging resistance requirements are high, and it needs to pass the solvent resistance test, dipping paint resistance test, and thermal effect test. At present, the commonly used rubber of JEM is CPE, which has excellent weather resistance and aging resistance. It has more than 10 years of application history in the cable industry. The technology is mature, but its aging resistance and solvent resistance are not as good as ECO rubber. [0003] ECO rubber is a polymer formed by the homopolymerization of epichlorohydrin or the copolymerization of epichlorohydrin and ethylene oxide. However, in the application of ECO rubber in cabl...
