Super-strength abrasion-resistant rubber

Abstract

The invention discloses super abrasion-resistant rubber. The super abrasion-resistant rubber is prepared from the following substances in parts by weight: 50 parts of buna-n rubber, 30 parts of carbon black, 20 parts of zinc oxide, 2 parts of stearic acid, 1 part of sulfide, 2 parts of lead tetroxide, 2 parts of titanium dioxide, 3 parts of anti-aging agent, 0.5 part of accelerant, 0.6 part of scorch retarder and 1 part of zinc stearate; and the accelerant is any one or a combination of two of triethylene diamine, stannous octoate or aluminum acetylacetonate. Compared with the prior art, by adjusting the ratio of the formula, the abrasion resistant degree of the rubber can be achieved, and the high temperature resistance and the stretching resistance can be improved.

Description

technical field [0001] The invention relates to the field of rubber, in particular to a super wear-resistant rubber Background technique [0002] Nitrile rubber is a polymer formed by the emulsion copolymerization of butadiene and acrylonitrile. Nitrile rubber is known for its excellent oil resistance, and its oil resistance is second only to polysulfide rubber, acrylic rubber and fluororubber. In addition, nitrile rubber also has good wear resistance, aging resistance and air tightness, but its ozone resistance, electrical insulation and cold resistance are relatively poor, while its electrical conductivity is relatively good. Therefore, it is widely used in the rubber industry. In our daily life, we often need a super-strength wear-resistant rubber, such as car tires. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a super-strength wear-resistant rubber. [0004] In order to solve the above problems, what ...
