Composite abrasion-resistant rubber liner plate and preparation method thereof

Abstract

The invention relates to a composite abrasion-resistant rubber liner plate and a preparation method thereof. The rubber liner plate is formed by bonding a surface layer composite rubber plate and a lower layer elastic rubber plate, and the composite rubber plate is formed by mixing isoprene rubber, composite fibers, a reinforcing agent, a filler, a vulcanizing agent and composite resin; and the reinforcing agent is prepared from sepiolite fabric, nano zinc powder and ethyl orthosilicate, and the filler is prepared from nanocrystalline boehmite, ammonium fluoride, boric acid, monatomic silicon powder and magnesium borate whiskers. The rubber liner plate is formed by the surface layer composite rubber plate and the lower laser elastic rubber plate, and the reinforcing agent and filler of special components and the composite resin are added into the surface layer composite rubber plate, the abrasion resistance and the strength are greatly improved; and moreover, a buffering agent is added into the lower layer elastic rubber plate, and the impact force transferred by the surface layer composite rubber plate can be absorbed, so that the impact resistance, fracture resistance and abrasion resistance of the whole rubber liner plate can be improved.

Description

technical field [0001] The invention belongs to the field of polymer materials, in particular to a composite wear-resistant rubber liner and a preparation method thereof. Background technique [0002] Rubber is a kind of elastic polymer, which can be divided into natural rubber and synthetic rubber according to raw materials. Natural rubber is processed by extracting colloid from rubber trees, rubber grass and other plants, and synthetic rubber is made of various monomers through polymerization reaction. And get. Rubber products are widely used in all aspects of industry or life, especially in the industrial field, it is often necessary to use linings made of rubber materials to protect certain parts of the equipment to prevent them from being damaged due to wear, erosion, erosion, etc. However, whether it is natural rubber or synthetic rubber, its wear resistance is not ideal. Contents of the invention [0003] In order to solve the problem that the wear resistance of e...
