Abstract

The invention relates to the technical field of water-resistant coiled materials, particularly a physicochemical-crosslinking-reaction high-polymer self-adhesive water-resistant coiled material which comprises a weather-resistant protective sand layer, a high-polymer adhesive layer on the weather-resistant protective sand layer, and a high-polymer composite material sheet layer on the high-polymer adhesive layer. The high-polymer composite material sheet is a polyolefin-nano kaolin composite material, and has high strength and high elongation at break. The synthetic high-polymer adhesive is an electron-rich system containing extended pi bond, and can implement permanent bonding with cast-in-place concrete.

Description
