The invention provides a wear-resistant synthetic rubber, which is mainly prepared from natural rubber sheets, cis-polybutadiene rubber, butadiene styrene rubber, chlorinated polyethylene rubber, grease DOP, polytetrafluoroethylene, nano magnesium hydroxide, oligomer ester, an accelerant, a reinforcing agent, an anti-vulcanization reducing agent, a vulcanizing agent and a filler. According to theinvention, the wear-resistant synthetic rubber with shore hardness of 60, tensile strength of 23, elongation at break of 850%, elastic modulus of 53% and Akron wear (cm<2>) of 0.035 g can be preparedfrom the raw materials through processes of plastication, mixing and the like, and the problem that mechanical parts for conveying ore and other materials are prone to abrasion and corrosion to causethe short service life is solved.
Description
technical field [0001] The invention relates to the technical field of rubber materials, in particular to a wear-resistant synthetic rubber. Background technique [0002] At present, in the machinery used to transport ore and other materials, such as mine slurry pumps, impellers, and conveyor belts, the surfaces are covered with rubber layers, and its function is to reduce wear and corrosion between mechanical parts. At present, the Acron wear of the rubber layer covered on the surface of its mechanical parts is only 0.7-0.9 (cm2), and the rubber layer is very easy to wear and fall off, thereby causing the wear and tear between the mechanical parts to be accelerated and corroded, and the service life is shortened. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a wear-resistant synthetic rubber with a long service life. [0004] Realize the technical scheme of the present invention as: ...
