NOVELTY - Hot-melt pressure-sensitive adhesive, comprises 15-30 pts. wt. styrene-isoprene-styrene block copolymer, 1-10 pts. wt. butyl rubber/graphene composite rubber, 20-40 pts. wt. plasticizer, 35-50 pts. wt. tackifying resin, 0.5-3 pts. wt. anti-aging agent, 0.5-1.5 pts. wt. silane coupling agent, 0.5-3 pts. wt. cross-linking agent, and 0.5-1.5 pts. wt. cross-linking auxiliary agent. USE - The hot-melt pressure-sensitive adhesive is useful in waterproof coiled materials (claimed). ADVANTAGE - The hot-melt pressure-sensitive adhesive has super-strong water resistance, and large specific surface area. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: Preparing hot melt pressure-sensitive adhesive, comprising heating and mixing styrene-isoprene-styrene block copolymer, plasticizer and silane coupling agent to obtain styrene-isoprene-styrene block copolymer completely dissolved in the plasticizer the first mixture, shearing and mixing butyl rubber/graphene composite rubber and anti-aging agent to obtain powdery second mixture, adding the first mixture, crosslinking agent, and crosslinking auxiliary agent to the second mixture for refining to obtain third mixture, and adding tackifying resin to the third mixture for refining to obtain a hot-melt pressure-sensitive adhesive; and Waterproof coiled material, comprising a sheet layer, a hot-melt pressure-sensitive adhesive layer composed of the hot-melt pressure-sensitive adhesive, and an isolation layer.
