Abstract

The invention provides a hot melt adhesive for hot melt adhesive for non-asphaltic base pre-laid polymeric waterproof rolls. The The hot melt adhesive for non-asphaltic base pre-laid polymeric waterproof rolls comprises 10-30 parts of naphthenic oil, 0.1-3 parts of an antioxidant, 0.1-1 part of a silane coupling agent, 0.1-1 part of nanometer titanium dioxide, 0.1-1 part of nanometer zinc oxide, 20-32 parts of a styrene-isoprene-styrene copolymer, 1-5 parts of a styrene-hydrogenated isoprene-diblock copolymer, 15-30 parts of C5 / C9 copolymerized petroleum resin and 20-35 parts of C5 hydrogenated petroleum resin. The invention also provides a preparation method of the hot melt adhesive for non-asphaltic base pre-laid polymeric waterproof rolls. The hot melt adhesive has the advantages of excellent ultraviolet resistance, good low temperature resistance, good high temperature resistance, and appropriate cohesion strength, initial adhesion and peel strength, can be firmly pasted to a base material, can be firmly pasted to reaction sand particles spread on the surface of the base material, and has good weatherability.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a hot melt adhesive for a non-asphalt-based pre-paved polymer waterproof coiled material and a preparation method thereof, and also relates to a non-asphalt-based pre-paved polymer waterproof coiled material. Background technique [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, roads and landfills. It is a rollable flexible building material product that can resist external rainwater and prevent underground leakage. There is no leakage connection between objects, and it is the first barrier for the waterproofing of the whole project, which plays a vital role in the whole project. Waterproof membrane products mainly include bitumen waterproof membrane and polymer waterproof membrane. Asphalt waterproofing membrane is dip-coated with asphalt by base paper, fiber felt and other carcass materials, and the surface is sprinkled with powdery, g...
