Abstract

The invention provides a highly-abrasion-resistant butadiene-acrylonitrile-rubber vulcanized rubber and a preparation method thereof. The highly-abrasion-resistant butadiene-acrylonitrile-rubber vulcanized rubber comprises the following components according to parts by weight: 100 parts of butadiene-acrylonitrile rubber, 3-8 parts of active agent, 1-6 parts of antiager, 2-6 parts of erucamide, 50-150 parts of reinforcing filler and 3-8 parts of vulcanizing accelerator, wherein acrylonitrile content in the butadiene-acrylonitrile rubber is 34-41 percent by weight, and Mooney viscosity (ML[1+4] of the butadiene-acrylonitrile rubber is 45-70. The preparation method of the butadiene-acrylonitrile-rubber vulcanized rubber comprises the steps of A. mixing and processing and B. recycled processing and vulcanization. The butadiene-acrylonitrile-rubber vulcanized rubber has reasonable component mixing and higher abrasion resistance. The highly-abrasion-resistant butadiene-acrylonitrile-rubber vulcanized rubber prepared according to the method has high elongation and long service life.

Description

technical field [0001] The invention relates to a synthetic rubber and a preparation method thereof, in particular to a highly wear-resistant nitrile rubber vulcanizate and a preparation method thereof. It belongs to the technical field of polymer materials. Background technique [0002] Nitrile butadiene rubber is prepared by emulsion polymerization of butadiene and acrylonitrile. It is a synthetic rubber with good oil resistance (especially alkane oil) and aging resistance. There are five types of acrylonitrile content (%) in nitrile rubber: 42-46, 34-41, 31-34, 25-30, 18-24. The more acrylonitrile content, the better the oil resistance, but the cold resistance will decrease accordingly. It can be used for a long time in the air at 120°C or in the oil at 150°C. In addition, it also has good water resistance, air tightness and excellent bonding performance. Widely used in the manufacture of oil-resistant products such as hoses, tapes, rubber rollers, capsules, sealing p...
