Abstract

The invention discloses a cohesion-enhanced butyl rubber hot-melt pressure-sensitive adhesive. Its components and parts by weight are: 10-35% of butyl rubber, 3-20% of bromobutyl rubber, and 3-20% of other matrix resins. 18%, imidazole derivatives 0.05-1%, tackifying resin 10-35%, plasticizer 5-35%, reinforcing filler 18-55%, antioxidant 0.1-0.6%. The invention also discloses a preparation method. The butyl rubber hot-melt pressure-sensitive adhesive of the present invention has reversible thermal processability, and has the ability to recoat and bond in a heated state.

Description

technical field [0001] The invention relates to the field of butyl rubber hot-melt pressure-sensitive adhesive, in particular to a cohesive-reinforced butyl rubber hot-melt pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is a material that implements interfacial bonding by pressure. According to the main resin composition, it can be divided into two types: rubber type and resin type. In addition to the main component of rubber, rubber pressure-sensitive adhesives should be added with tackifying resin, plasticizer, filler, antioxidant, anti-aging agent and even vulcanizing agent, etc. Auxiliary. Among the rubber pressure-sensitive adhesives, butyl rubber pressure-sensitive adhesives have very good weather resistance and water tightness due to their less unsaturated double bonds and the presence of methyl groups. Therefore, it is mostly used in construction, medical and industrial fields as waterproof, s...
