Problems solved by technology

However, the current reaction-bonded wet-laid polymer waterproof membrane has the following defects in use: if cracks occur on the laying surface, the membrane will be stretched, such as the base layer of the membrane cannot relieve the tension formed during stretching. stress, it is easy to cause cracks or even breakage of the coiled material, which affects the waterproof and sealing performance of the coiled material

Abstract

The invention provides a reaction bonding wet-laid polymer waterproof coiled material and a preparation method thereof, belonging to the technical field of waterproof materials. The waterproof membrane includes a polyolefin thermoplastic elastomer base layer on the upper layer, a modified asphalt adhesive layer in the middle, and an isolation film protection layer on the lower layer. The polyolefin thermoplastic elastomer is mainly made of the following raw materials: polyisobutylene, ethylene and octene copolymer, ethylene-propylene rubber, modified polypropylene, antioxidant, anti-aging agent, softener, filler; the preparation method is to prepare the modified asphalt binder and polyolefin thermoplastic elastomer respectively , bond the two with heat and pressure, control the thickness and set the shape, cover the protective layer of the isolation film, and wind up. The waterproof membrane is made of modified asphalt binder to make a base layer with more suitable performance, by increasing the crack resistance of the base layer and increasing the bonding force between the modified asphalt binder and the base layer, avoiding the appearance of the membrane Cracks ensure the waterproof sealing effect of the membrane.

Description

【Technical field】 [0001] The invention relates to the technical field of waterproof membranes, in particular to a reaction-bonded wet-laid polymer waterproof membrane and a preparation method thereof. 【Background technique】 [0002] Waterproof membrane is mainly used in building walls, roofs, tunnels, highways, subways, landfills, etc., to resist external rainwater and groundwater leakage, a flexible building material product that can be rolled into rolls. There is no leakage connection between the engineering foundation and the building. It is the first barrier for the waterproofing of the entire project and plays a vital role in the entire project. According to its main waterproofing materials, it can be divided into asphalt waterproofing materials, polymer modified There are three types of permanent waterproof membranes and synthetic polymer waterproof membranes. Bitumen Waterproofing Membrane Asphalt waterproofing membrane is a rollable sheet waterproof material made by...
