Abstract

The invention provides a reaction-bonding wet-laid polymer waterproofing membrane and a preparation method thereof, and belongs to the technical field of waterproofing materials. The waterproofing membrane comprises a polyolefin thermoplastic elastomer base layer located at the upper layer, a modified asphalt adhesive layer located at the middle layer and a separator film protection layer locatedat the lower layer, and the polyolefin thermoplastic elastomer is mainly made from polyisobutylene, an ethylene-octene copolymer, ethylene-propylene rubber, modified polypropylene, an antioxidant, anti-aging agent, a softener and a filler. The preparation method comprises the following steps: respectively preparing a modified asphalt adhesive and a polyolefin thermoplastic elastomer, performing thermocompression bonding, performing thickness-controlled shaping, covering the shaped product with the separator film protection layer, and winding the covered product to obtain the waterproofing membrane. A tire base layer with a good adapting performance to the modified asphalt adhesive is manufactured, and the crack resistance of the tire base layer and the adhesion between the modified asphaltadhesive and the tire base layer are increased to avoid the membrane from cracking, so the waterproof sealing effect of the membrane is ensured.

Description

【Technical Field】 [0001] The invention relates to the technical field of waterproof coiled materials, in particular to a reaction-bonded wet-laid polymer waterproof coiled material and a preparation method thereof. 【Background technique】 [0002] Waterproof coiled material 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 a roll. There is no leakage connection between the project foundation and the building. It is the first barrier for the entire project’s waterproofing and plays a vital role in the entire project. According to its main waterproof components, it can be divided into asphalt waterproof materials and polymer modified materials. There are three types of waterproof membranes and synthetic polymer waterproof membranes. Asphalt waterproof membrane is a rollable sheet-like waterproof material made by impregnating the base...
