Abstract

The invention relates to the field of waterproof building materials, in particular to a modified asphalt waterproof coiled material, and aims to solve the problems such that the common polymer waterproof coiled material is low in tensile performance and poor in environment friendliness and the common modified asphalt waterproof coiled material is short in life. The modified asphalt waterproof coiled material comprises modified asphalt, polypropylene fiber cloth and PE (polyethylene) film; the modified asphalt is synthetically made from, by weight, 40 to 50 parts of asphalt, 20 to 30 parts of high-density polyethylene, 15 to 30 parts of SBS (styrene butadiene styrene) rubber, 0.2 to 2 parts of stabilizer, 0.5 to 1 part of antioxidant, 0.1 to 2 parts of photo-stabilizer, and 10 to 20 parts of filler.

Description

technical field [0001] The invention relates to the field of waterproof building materials, in particular to a modified bitumen waterproof coiled material. Background technique [0002] Since the 1970s, developed countries in the world have begun to change in the structure of waterproof materials, gradually developing to new waterproof materials such as modified asphalt, self-adhesive, and synthetic polymer materials. At present, foreign new waterproof materials have accounted for more than 90% of the total market, and product quality, function, and service life have reached a relatively high level. Since the application of asphalt membranes in my country's waterproof projects in the 1970s, asphalt waterproof materials have always been the leading product for building waterproofing, accounting for about 70% of the total market recently, and polymer waterproof materials accounted for only about 10%. Others For waterproof coatings and other waterproof materials. Polyethylene ...
