Abstract

The invention belongs to the technical field of rubber and plastic products, and proposes a low-temperature-resistant rubber and plastic product and a preparation method thereof, comprising the following components in parts by weight: 15 to 20 parts of nitrile rubber, 2 to 3 parts of butadiene rubber, polyvinyl chloride 4-7 parts of resin, 4-7 parts of foaming agent, 3-5 parts of carbon black, 10-13 parts of rubber process oil, 4-7 parts of low-temperature modifier, 0.3-0.5 parts of active agent, 0.1-0.1 parts of stearic acid 0.3 parts, 5-9 parts of aluminum tripolyphosphate, 3-5 parts of barium metaborate, 10-12 parts of filler, 3-5 parts of protective wax, 2-4 parts of accelerator, 0.1-0.3 parts of vulcanizing agent, the low temperature The modifier consists of the following components in parts by weight: 5-8 parts of dioctyl sebacate, 3-5 parts of polydimethylsiloxane, 0.5-1 part of N-methylpyrrolidone, triphenylmethane 2.5-4 parts of isocyanate. Through the above technical solution, the problem that the minimum service temperature of the rubber and plastic products in the prior art can only reach -20°C and the low temperature resistance is poor is solved.

Description

technical field [0001] The invention belongs to the technical field of rubber and plastic products, and relates to a low-temperature resistant rubber and plastic product and a preparation method thereof. Background technique [0002] The abbreviation of rubber and plastic products is rubber and plastic products, and rubber and plastic products are widely used in industrial, civil, military and other fields. Existing rubber and plastic insulation products are generally obtained by using nitrile rubber and polyvinyl chloride resin as the main material, adding other auxiliary materials and blending at high temperature, and then adding vulcanizing agent and foaming agent through vulcanization and foaming. The current production of rubber and plastic products can only be used at a minimum temperature of -20°C, which limits the use environment of rubber and plastic products. Contents of the invention [0003] The invention proposes a low-temperature-resistant rubber and plastic...
