Description

technical field [0001] The invention relates to a kind of rubber, in particular to a kind of waterproof butyl rubber, which belongs to the technical field of chemical industry. Background technique [0002] Butyl rubber (HR) is a kind of synthetic rubber obtained by copolymerizing isobutylene and a small amount of isoprene, in which the isoprene content is generally 1.5-4.5%, white to light gray, odorless and tasteless. [0003] Butyl rubber is a non-polar saturated rubber: due to its regular molecular structure, non-polar side groups, large volume, large steric hindrance and high degree of saturation, butyl rubber has many unique properties. Butyl rubber has excellent air tightness. Among all kinds of rubber, the air tightness of butyl rubber is second to none. Its air permeability coefficient at room temperature is 1 / 20 of natural rubber, 1 / 30 of cis-butadiene rubber, 1 / 8 of styrene-butadiene rubber, and 1 / 13 of ethylene-propylene rubber. Butyl rubber has high chemical ...
