Abstract

The invention relates to an acrylic acid modified asphalt cement-based and water-proof coating and a preparation method. The emulsified acrylic acid modified asphalt cement-based and water-proof coating consists of component A and component B; wherein, the mixture ratio of the component A to the component B is from 1 : 0.5 to 1.5 (in weight); wherein, the raw materials of component A and the weight percentage thereof are respectively as follows: acrylic emulsion or amphetamine emulsion accounting for 40 to 70 percent, emulsified asphalt accounting for 10 to 50 percent, filler accounting for 8 to 20 percent, accessory ingredient accounting for 0.1 to 3 percent and water accounting for 1 to 19.0 percent; the raw materials of component B and the weight percentage thereof are as follows respectively: cement accounting for 70 to 100 percent and filler accounting for 0 to 30 percent. The acrylic acid modified asphalt cement-based and water-proof coating has the advantages of strong binding power with the base, high tensile strength, large unit extension, low cost and environment protection.

Description

technical field [0001] The invention relates to a water-emulsion acrylic modified asphalt cement-based waterproof coating for buildings, structures, roads and bridges, tunnels and culverts for waterproofing, seepage prevention and leakage prevention and a preparation method thereof. Background technique [0002] The current coating waterproof technology and materials mainly use the following technologies and materials: [0003] 1. Solvent-based waterproof coating. There are mainly polyurethane waterproof coatings, polyurethane modified bitumen waterproof coatings, SBS modified bitumen waterproof coatings, SBR modified bitumen waterproof coatings, rubber waterproof coatings, silicone rubber waterproof coatings, etc. Their common feature is that organic solvents are used as carriers and diluents, and generally have the advantages of high strength, high elongation, and good impermeability. However, due to the use of organic solvents, the pollution to the environment and the i...
