Abstract

The invention discloses high-damping chlorinated butyl rubber and a method for preparing the same. The high-damping chlorinated butyl rubber comprises, by weight, 100 parts of chlorinated butyl rubber, 12.5-25 parts of ethylhexyl triazone rubber master batch, 2-4 parts of vulcanizing agents, 1-1.5 parts of accelerators, 1-3 parts of stearic acid, 1-3 parts of nanometer zinc oxide and 1-3 parts of anti-aging agents. The chlorinated butyl rubber, the ethylhexyl triazone rubber master batch, the vulcanizing agents, the accelerators, the stearic acid, the nanometer zinc oxide and the anti-aging agents are mixed with one another to obtain the high-damping chlorinated butyl rubber. As proved by experiments, the high-damping chlorinated butyl rubber and the method have the advantages that the chlorinated butyl rubber is modified by the aid of the ethylhexyl triazone rubber master batch, and accordingly chlorinated butyl rubber materials which are excellent in damping property and mechanical property and wide in damping temperature range can be obtained; processes for preparing the high-damping chlorinated butyl rubber are economical and practical and are easy to implement and low in cost, and scale production can be facilitated.

Description

technical field [0001] The invention relates to a damping rubber and a preparation method thereof, in particular to a high-damping chlorinated butyl damping rubber and a preparation method thereof, belonging to the technical field of damping materials. Background technique [0002] Chlorinated butyl rubber (CIIR) is made by passing chlorine gas into butyl rubber solution. It has the advantages of high reactivity, fast vulcanization speed, good adhesion, etc., so it is widely used in the production of tires, rubber hoses, tapes, industrial rubber products, pharmaceutical rubber products, cultural and sports rubber products, building sealing materials and chemical anti-corrosion linings. Wait. At the same time, due to the replacement of chlorine atoms, the intermolecular friction coefficient increases, and the damping performance of chlorobutyl rubber is better, so it can be used to make various damping and shock absorbing materials. [0003] However, chlorinated butyl rubbe...
