High-strength rubber and preparation method thereof

Abstract

The invention discloses high-strength rubber and a preparation method thereof. The rubber is prepared from 30-60 parts of butadiene-acrylonitrile rubber, 20-50 parts of chloroprene rubber, 8-25 parts of natural rubber, 3-11 parts of titanium dioxide, 2-7 parts of talcum powder, 3-7 parts of zinc oxide, 8-15 parts of chlorinated polyethylene, 6-10 parts of octyl phenolic resin, 15-25 parts of reinforcing filler, 5-13 parts of vulcanizing activator, 0.8-1.8 parts of vulcanizing agent, 1.2-3 parts of vulcanizing accelerator, 6-10 parts of plasticizer and 2-4 parts of anti-aging agent. A coating has the advantages of being high in strength, resistant to high-pressure shock, not prone to breaking, good in wide-temperature range adaptability, capable of meeting wide-temperature range utilization requirements, reliable in quality, durable in use, low in cost, easy to prepare and suitable for large-scale production.

Description

technical field [0001] The invention relates to a rubber, in particular to a high-strength rubber and a preparation method thereof. Background technique [0002] Among the existing rubber materials, silicone rubber with excellent high and low temperature performance has low mechanical properties and difficult bonding, which limits its scope of use; while other rubber materials in the market have poor performance in wide temperature ranges, such as low temperature crystallization and hardening resulting in shearing. The cutting modulus increases sharply; the thermal stability at high temperature decreases, which cannot meet the requirements of wide temperature range use, especially when using rubber on deep-sea submarines and other equipment, the weight should be light, and the ability to withstand high pressure should be high, and it will not be easily broken. Contents of the invention [0003] To meet the above needs, the present invention provides a high-strength rubber ...
