Abstract

The invention belongs to the technical field of rubber and plastic products. The invention provides a low-corrosivity rubber and plastic product and a preparation method thereof. The low-corrosivity rubber and plastic product is prepared from the following components in parts by weight: 15 parts of nitrile rubber, 5 parts of polyvinyl chloride resin, 3 parts of vinyl acetate copolymer resin, 20 parts of talcum powder, 2 parts of polydimethylsiloxane, 13 parts of a plasticizer, 1 part of a heat stabilizer, 2 parts of protective wax, 3 parts of carbon black, 0.2 part of an active agent, 0.1 partof stearic acid, 10 parts of a flame retardant, 0.1 part of an anti-aging agent, 1 part of an accelerator, 0.1 part of a vulcanizing agent, and 4-7 parts of a foaming agent, and the vulcanizing agentis 4, 4'-dithiodimorpholine. By means of the technical scheme, the problem that in the prior art, a rubber and plastic product has high corrosion to a metal interface is solved.

Description

technical field [0001] The invention belongs to the technical field of rubber and plastic products, and relates to a low-corrosion rubber and plastic product and a preparation method thereof. Background technique [0002] Rubber and plastic thermal insulation products are made of nitrile rubber and polyvinyl chloride resin as the main material, calcium carbonate as the filler, and other auxiliary materials are added to blend at high temperature, and then sulfur, accelerators and foaming agents are added to obtain rubber and plastic through vulcanization and foaming. products. Due to the current use of chlorine compounds in the production of rubber and plastic products, the content of chloride ions in the products is high; when sulfur is used as a vulcanizing agent, free sulfur will be precipitated; calcium carbonate is used as a filler to make the products slightly acidic; based on the above factors, the produced rubber and plastic products Products will corrode the metal i...
