Abstract

The invention provides an environment-friendly high molecular self-adhesive waterproof rolled material, and relates to the field of construction materials. A preparation method comprises the followingsteps: putting phenolic resin, a plasticizer and a heat stabilizer into a hot mixer to be uniformly stirred, and putting extending oil, light calcium carbonate, an antioxidant, an anti-ultraviolet agent and thermoplastic polyurethane to be uniformly stirred; putting the obtained material into an extruding machine, and performing rolling, pulling, winding and shaping on the extrudate to obtain a base layer of the waterproof rolled material; adding phenolic resin, fibrous protein, lignocellulose, ethyl acetate, polyisobutylene, sodium alginate, tetraethyl orthosilicate and modified nitrile rubber to a high-speed mill to be mixed so as to obtain adhesive paste; and compounding the adhesive paste and the base layer of waterproof rolled material, and arranging an anti-sticking film on a self-adhesive layer formed by the adhesive paste so as to obtain the environment-friendly high molecular self-adhesive waterproof rolled material. The base layer of the waterproof rolled material and the adhesive layer are made from environment-friendly materials, and the waterproof rolled material does not have harmful substances and has good use effects.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an environment-friendly polymer self-adhesive waterproof coiled material. Background technique [0002] Waterproof membrane is a commonly used material in building construction. It is mainly used for waterproof construction of building roofs and underground works, and plays a vital role in resisting the leakage of rainwater and groundwater. The polymer materials used in waterproof membranes generally contain toxic substances, which are easy to cause pollution, and the adhesive layer usually used in waterproof membranes will release free formaldehyde during production and use, which seriously endangers human health. Therefore, in Under the situation that consumers' awareness of environmental protection is increasing day by day, it is urgent to provide a new environment-friendly polymer self-adhesive waterproof membrane. Contents of the invention [0003] The object of the pres...
