Abstract

The invention discloses modified butyl rubber. The modified butyl rubber comprises the following components in parts by weight: 15-40 parts of butyl rubber, 8-15 parts of maleic anhydride, 5-10 parts of sulfonyl chloride, 7-10 parts of plasticizer, 0.5-2 parts of vulcanizing agent, 0.5-1 part of antioxidant, and 20-30 parts of inorganic filler. The modified butyl rubber disclosed by the invention is added with the plasticizer, so that the guarant viscosity is lowered; at the room temperature, the modified butyl rubber has high elasticity and high strength of the common vulcanized rubber; the added vulcanizing agent is produced in a vulcanizing manner, so that the holding power of a product is improved, and the peel strength is better.

Description

Technical field [0001] The invention relates to a modified butyl rubber, which belongs to the field of high-performance materials. Background technique [0002] Halogenation modification of butyl rubber has become a more mature butyl rubber modification technology. Its main products are chlorinated butyl rubber and bromobutyl rubber. Chlorinated butyl rubber retains the low air permeability, shock absorption, ozone resistance and chemical resistance of ordinary butyl rubber, but also adds the characteristics that ordinary butyl rubber does not have, such as fast vulcanization speed and good heat resistance. [0003] However, the polarity of chlorinated butyl rubber is still weak, resulting in poor compatibility with polar polymers. Therefore, it is necessary to provide a new technical solution to solve the above-mentioned problems. Summary of the invention [0004] The purpose of the present invention is to provide a modified butyl rubber with excellent performance. [0005] In or...
