Abstract

The invention belongs to the technical field of rubber and plastic products. The invention provides a low-temperature-resistant rubber and plastic product and a preparation method thereof. The productis prepared from the following components in parts by weight: 15-20 parts of nitrile rubber, 2-3 parts of cis-1,4-polybutadiene rubber, 4-7 parts of polyvinyl chloride resin, 4-7 parts of a foaming agent, 3-5 parts of carbon black, 10 to 13 parts of rubber operating oil, 4-7 parts of a low-temperature modifier, 0.3-0.5 part of an active agent, 0.1-0.3 part of stearic acid, 5 to 9 parts of aluminum tripolyphosphate, 3-5 parts of barium metaborate, 10-12 parts of a filler, 3-5 parts of protective wax, 2-4 parts of an accelerant and 0.1-0.3 part of a vulcanizing agent. The low-temperature modifier is prepared from the following components in parts by weight: 5 to 8 parts of dioctyl sebacate, 3 to 5 parts of polydimethylsiloxane, 0.5 to 1 part of N-methyl pyrrolidone and 2.5 to 4 parts of triphenylmethane triisocyanate. By means of the technical scheme, the problems that in the prior art, the lowest use temperature of a rubber and plastic product can only reach -20 DEG C, and resistance to low temperature is poor are 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] Rubber and plastic products are abbreviated as rubber and plastic products, and rubber and plastic products are widely used in industries, civil, military and other fields. Existing rubber and plastic insulation products generally use nitrile rubber and polyvinyl chloride resin as main materials, add other auxiliary materials for high temperature blending, and then add vulcanizing agent and foaming agent to vulcanize and foam. At present, the use temperature of rubber and plastic products can only reach -20℃, which limits the use environment of rubber and plastic products. Summary of the invention [0003] The present invention provides a low-temperature resistant rubber-plastic product and a preparation method thereof, which solves the problem that ...
