Abstract

The invention discloses a plastic waterproof plate and a preparation method therefor. The plastic waterproof plate is prepared from raw materials comprising an ethylene-vinyl acetate copolymer, linear low density polyethylene, asphalt, filler and an antioxidant. The plastic waterproof plate disclosed by the invention has excellent aging resistance and chemical medium corrosion resistance of the asphalt, excellent flexibility, tensile strength and wear resistance of the linear low density polyethylene and excellent low-temperature flexibility and sweat soldering performance of the ethylene-vinyl acetate copolymer. The composition of the product is environmentally friendly and the product can be widely suitable for waterproofness and seepage resistance of civil engineering such as a plurality of tunnels, underground civil engineering, city subways, water conservancy, artificial lakes, refuse landfills, waste residue treatment fields of petroleum plants, sewage adjusting pools and the like.

Description

technical field [0001] The invention relates to a plastic waterproof board and a preparation method thereof, belonging to the field of building chemicals. Background technique [0002] At present, the waterproof materials used in underground waterproofing projects generally include asphalt waterproof membranes, high-density polyethylene self-adhesive film waterproof membranes, EPDM membranes, and plastic waterproof panels. When asphalt coils are constructed underground, hot-melt construction produces smoke and other harmful substances, which is not conducive to human health and environmental protection; high-density polyethylene self-adhesive film waterproof coils have poor bendability and compliance, and the price is relatively high. High; the cost of EPDM coils is relatively high, and it is not easy to bond and construct. [0003] Now there is a plastic waterproof sheet material named asphalt modified on the waterproof sheet market, but it is called an asphalt modified pl...
