Abstract

The invention discloses butadiene styrene rubber modified asphalt waterproofing coating used for a building. Raw materials of the butadiene styrene rubber modified asphalt waterproofing coating are asphalt, waste machine oil, talcum powder, butadiene styrene rubber, zinc-aluminum alloy powder, inositol hexaphosphate, isopropanol, sodium hypophosphite, C18 alcohol, glycerol, polydimethylsiloxane and benzalkonium chloride, wherein the asphalt is a mixture of No. 10 asphalt and No. 100 asphalt in a mass ratio of (10-20):(1-2); and the zinc-aluminum alloy powder comprises the following componentsin mass percent: 10-30% of Zn and the balance of Al and inevitable impurities. Compared with the prior art, the waterproofing coating disclosed by the invention is safer and more environmentally friendly, can be directly brushed without adding a diluent, is not brittle at low temperature of minus 25 DEG C and does not flow at high temperature of 80-85 DEG C; and bonding strength reaches up to 0.8-1.1MPa, wet substrate bonding strength reaches up to 0.5-0.7MPa, elongation at break is more than or equal to 600%, and integral waterproof performance is good.

Description

technical field [0001] The invention relates to the field of building waterproof coatings, in particular to a styrene-butadiene rubber modified asphalt waterproof coating for buildings. Background technique [0002] Building waterproof materials refer to materials that prevent rainwater, groundwater, water supply and drainage, corrosive liquids, and moisture and steam in the air from intruding into buildings. The parts of the building that need to be waterproofed are mainly the roof, wall, ground and basement, and the construction is mainly carried out through coating, spreading, filling, pouring, bonding and other processes. Since the development of domestic waterproof materials, an industrial system with relatively complete categories and relatively complete production and application technologies has basically been formed. The types include modified asphalt membranes, polymer waterproof membranes, waterproof coatings, sealing materials, plugging materials and rigid waterp...
