Wear-resistant composite material with ceramic embedded in rubber and preparation method thereof

Abstract

The invention discloses a wear-resistant composite material with ceramic embedded in rubber and a preparation method thereof. The wear-resistant composite material comprises a rubber substrate, the rubber substrate is provided with a plurality of blind holes, wear-resistant ceramic blocks with the sizes matched with the sizes of the blind holes are embedded in the blind holes, and the rubber substrate and the wear-resistant ceramic blocks are tightly matched with each other or bonded with each other. During rubber vulcanization, the pre-treated wear-resistant ceramic blocks are embedded in the rubber, and the rubber and the wear-resistant ceramic blocks are tightly matched with each other or bonded with each other. The composite material of the invention not only has the advantages of the rubber material such as good plasticity and impact resistance, but also has the advantages that the ceramic material has high hardness and excellent wear resistance. Therefore, the composite material can bear the working condition with large impact loads, and overcomes the defect that the highly wear-resistant ceramic material has no impact resistance.

Description

Wear-resistant composite material inlaid with ceramics in rubber and preparation method thereof technical field The invention relates to a wear-resistant composite material inlaid with ceramics on a rubber substrate and a preparation method thereof, belonging to the technical field of composite materials. Background technique In metallurgy, electric power, building materials, machinery, chemical industry and other industries, wear-resistant rubber and ceramics are often used to make wear-resistant parts, such as wear-resistant liners, conveyor belts, pipes, etc. The elastic deformation of the rubber material is large, and the elastic modulus is extremely small; the Poisson's ratio of the rubber is large, and the volume is almost unchanged during deformation. Rubber is not only widely used in the manufacture of vehicle tires, but also in the manufacture of wear-resistant parts for storage bins, funnels, chutes and other devices. The Chinese invention patent with the applic...
