Abstract
Description
Technical field
[0001] The present invention relates to the field of rubber, and more specifically, to a fast-vulcanized butyl rubber and a preparation method and application thereof. Background technique
[0002] The existing butyl rubber has a slow vulcanization speed, poor mutual adhesion and self-adhesion, and is difficult to use with other rubbers. As a result, the modification technology of butyl rubber has always been an important area to achieve its high performance. The bromobutyl rubber obtained by bromination modification not only has a faster vulcanization speed, but also gives the butyl rubber a polar group, which improves its self-adhesiveness and mutual adhesion. Bromination modification can be carried out in a solution or in an open mill. Due to the high corrosiveness of bromine, the requirements for equipment are high. At the same time, the by-product hydrogen bromide produced in the bromination process affects the follow-up of equipment and products. Applicati...
