Abstract

An abrasive-resisting synthetic rubber material and its production are disclosed. The rubber material consists of natural rubber sheet, cis-1,4-polybutadiene rubber, styrene-butadiene rubber, chlorinated polypropylene rubber, greaseDOP, polytef, nanometer-magnesium hydroxide, oligomer ester, improver, fortifier, sulfur-resisting reducer, vulcanizing agent and filling agent. The process is carried out by plastication milling and milling to obtain abrasive-resisting synthetic rubber material, which has Schau's hardness 60, stretch strength 23, elongation 23 and elasticity 53%. It has better abrasive-resisting and anticorrosive performances and short life.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, in particular to a wear-resistant synthetic rubber material and a preparation method thereof. Background technique [0002] 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 (cm 2 ), the rubber layer is easy to wear and fall off, resulting in accelerated wear and corrosion between mechanical parts, and shortened service life. Contents of the invention [0003] The object of the present invention is to provide a wear-resistant synthetic rubber material for covering machine parts so that they have a long service life. [0004] The second object o...
