▎ 摘  要

NOVELTY - Asphalt waterproofing membrane comprises an emulsified asphalt layer, a polyester tire base layer and a polyethylene film, where the emulsified asphalt layer is coated on the surface of the polyester tire base layer, and the polyethylene film covers the surface of the emulsified asphalt layer comprising composite asphalt particles having a particle size of 500 mu m or less, and the composite asphalt particles are compounded by graphene oxide, petroleum pitch and anionic polyacrylamide. USE - Asphalt waterproofing membrane. ADVANTAGE - The membrane has high temperature resistant, and is environmentally-friendly, and effectively improves the high temperature resistance of asphalt coils. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the waterproofing membrane, involving (a) mixing graphene oxide, asphalt, and anionic polyacrylamide, mixing at 85-100 degrees C for 56-72 hours using a ball mill at a rotation speed of 1000-1200 rpm to obtain a ball abrasive, cooling the obtained ball abrasive, and sieving out particles with a particle size of 500 ~Mm or less to obtain the composite asphalt particles, (b) sequentially using 80-120 pts. wt. composite asphalt particles, 200-300 pts. wt. water and 5-10 pts. wt. naphthenic oil, and homogenizing at high pressure to obtain an asphalt emulsion, and (c) coating the asphalt emulsion on the surface of the polyester tire base layer, drying, and covering with the polyethylene film to obtain the product.
