Rubber-coating roll with composite rubber-coating layer and method for preparing same

Abstract

The invention discloses a rubber-coating roll with a composite rubber-coating layer. The rubber-coating roll comprises a cylindrical rotary body made of a metallic material; the rubber composite material layer is coated on the rotary body; and the rubber composite material layer is made of a composite material formed by embedding wear resistant alloy blocks in rubber. The rubber-coating roll has the advantages of high toughness and plasticity and impact resistance of rubber materials and high hardness and wear resistance of wearing resistant alloy; and the rubber-coating roll can be used under working conditions of bearing a bigger impact load, and overcomes the defect that the impact resistance of the wearing resistant alloy materials is low.

Description

Covering roller with composite material covering layer and preparation method thereof technical field The invention relates to a rubber-coated roller with a composite material rubber-coated layer and a preparation method thereof. Background technique Covered rollers are widely used in metallurgy, mining, electric power, chemical industry, printing, textile, printing and dyeing and other industries, and are divided into conveying rollers, tension rollers, steering rollers, squeezing rollers, support rollers, etc. Rubber-covered rollers are also called rubber-coated rollers, which use metal materials to make a cylindrical rotating body, and then cover a layer of rubber material on the surface of the cylindrical rotating body. Most of the currently used cylindrical revolving bodies are made of seamless steel pipes, and the revolving bodies of some small rubber-covered rollers also use solid shaft structures. The covering layer is made of wear-resistant rubber. The structure ...

AI Technical Summary

Problems solved by technology

Wear-resistant alloys have high hardness and exhibit good wear resistance. For example, high-chromium cast iron alloys are materials with excellent abrasive wear resistance, but their impact resistance is poor.
