Abstract

The invention discloses high-performance modified polyurethane rubber which is composed of, by weight, 76-81 parts of polyurethane rubber, 21-25 parts of a filler, 13-17 parts of a chemical drug resistant agent, 10-14 parts of a high-temperature resistant agent, 7-11 parts of a dispersant and 5-9 parts of a thermal stabilizer. The filler is wollastonite powder, the chemical drug resistant agent is ethylene propylene rubber, the high-temperature resistant agent is polytetrafluoroethylene, the dispersant is hydroxyethyl cellulose, and the thermal stabilizer is bibasic lead stearate. The high-performance modified polyurethane rubber has the advantages of high waterproofness, high resistance to chemical drugs and high temperature, high strength and low cost.

Description

technical field [0001] The invention relates to the field of rubber and plastics, in particular to a high-performance modified polyurethane rubber. Background technique [0002] Polyurethane rubber is a series of elastomer materials containing more carbamate groups on the polymer main chain. It is actually polyurethane rubber, referred to as polyurethane rubber or polyurethane rubber or polyurethane elastomer. In addition to carbamate groups, the polymer chain also contains ester groups, ether groups, urea groups, aryl groups and aliphatic chains. It is usually formed by the reaction of oligomer polyol, polyisocyanate and chain extender. Polyurethane rubber forms different structures and varieties with different raw materials and proportions, reaction methods and conditions. But there are still many deficiencies in the prior art, such as poor water resistance, poor acid and alkali resistance, poor high temperature resistance, and poor use effect.
