Elastomer modified asphalt waterproof coiled material and preparation method thereof

Abstract

Elastomer-modified asphalt waterproofing membrane and preparation method thereof, elastomer-modified asphalt waterproofing membrane, is characterized in that it comprises base layer, petroleum asphalt layer, isolation material layer; base layer is covered with petroleum asphalt layer, petroleum asphalt The outer surface of the layer is covered with an isolation material layer; the petroleum asphalt layer is composed of: 40 parts of 10# asphalt, 15 parts of 90# asphalt, 3 parts of machine oil, 9 parts of modifier SBS, 6 parts of talcum powder, Guma 5 parts of Long resin, 7 parts of graphite, 7 parts of asphalt modified tackifier, and 8 parts of high-density polyethylene; the base layer is composed of 20 parts of polyester felt, 30 parts of glass fiber felt, Reinforced polyester felt is composed of 50 parts; it has good elongation performance, high high and low temperature resistance, water impermeability can reach 0.7MPa, and the product's low temperature flexibility can reach ‑40 ° C without cracks.

Description

technical field [0001] The invention relates to a preparation process of a waterproof coiled material, in particular to an elastomer modified asphalt waterproof coiled material and a preparation method thereof. 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. However, since asphalt membranes were used 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 ...
