A ceramic wear-resistant rubber tube and its manufacturing method

Abstract

The invention discloses an abrasion-resistant ceramic rubber tube. The rubber tube comprises a rubber tube body, wherein a plurality of ceramic bodies are embedded in the rubber tube body, and are uniformly arranged and embedded into an inner layer face of the tube body. The manufacturing method comprises the following steps: firstly, abrasion-resistant ceramic blocks are put in an acetone solution for de-esterification treatment, the ceramic blocks after immersed in the acetone solution and dried are put in a carbon tetrachloride and chromic acid mixed solution for oxidation treatment, and the ceramic blocks are taken out after immersion, and are dried; the treated ceramic blocks are coated with chemlok 607 once firstly, and coated with 220 adhesive once after dried, and then air-dried; rubber is coated with one layer of chemlok 205, and is attached to the arranged ceramic bodies.

Description

technical field [0001] The invention relates to a ceramic wear-resistant rubber tube and a manufacturing method thereof. Background technique [0002] In industries such as electric power, building materials, machinery, metallurgy, and chemical industry, wear-resistant rubber and ceramics are often used to make wear-resistant parts, such as wear-resistant pipes, conveyor belts, liners, 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. [0003] The Chinese invention patent with the application number of 93111075.0 "Ultra wear-resistant rubber liner for light and heavy load type cold material and its manufacturing method" uses natural rubber, styrene-but...

AI Technical Summary

Problems solved by technology

The combination of metal and ceramic improves the impact resistance of ceramics, but under the condition of large impact momentum of load, due to the poor deformation ability of metal deformation, it is easy to cause the ceramic material to fall off in pieces

Moreover, the weight of metal is larger than that of ceramics, and the weight of the metal-ceramic composite material is also much larger than that of ceramic materials, which makes installation inconvenient.

[0008] Application number is 93233642.6 Chinese invention patent "wear-resistant ceramic rubber liner" has proposed the technology that the ceramic top plate and the rubber layer bottom plate are bonded through the adhesive layer to make the wear-resistant liner, as the ceramic top plate of the wear-resistant working layer Since there is no rubber buffer in the lateral direction, it is easy to fall off in pieces under the action of impact load

[0009] Application number is 95247096.9 Chinese invention patent "ceramic rubber composite liner" is that ceramic block, rubber plate, metal plate are bonded together by thermal vulcanization, and application number is 93233642. Under the action of impact load, it will fall off in pieces
