Problems solved by technology

The waterproof coating also directly adds fillers, which makes the dispersion of fillers very poor
At the same time, the average solid content of the waterproof coating is 60%, and the average elongation at break is 455%, which makes the film thickness and film quality of the waterproof coating unsatisfactory, and it is difficult to adapt to harsh environments and climates.

Abstract

The invention relates to a composite emulsified asphalt waterproof coating and a preparation method thereof. The composite emulsified asphalt waterproof coating is prepared from the following raw materials in parts by weight: 150-220 parts of emulsified asphalt, 50-105 parts of a polymeric emulsion, 70-130 parts of inorganic powder, 0.5-2 parts of a stabilizer, 6-10 parts of a dispersant, 2-5 parts of a wetting agent, 1-3 parts of a thickener I, 1-3 parts of a thickener II, 2-7 parts of a defoaming agent and 15-40 parts of water. The invention further relates to a preparation method of the composite emulsified asphalt waterproof coating. The viscosity, strength, application property, solid content and storage stability of the emulsified asphalt waterproof coating are remarkably improved, and the cost is lowered to a great extent.

Description

technical field [0001] The invention relates to a water-emulsion asphalt waterproof coating and a preparation method thereof, in particular to an organic / inorganic composite water-emulsion asphalt waterproof coating and a preparation method thereof. Background technique [0002] Waterproof coatings are an important part of waterproof materials. According to the construction temperature, asphalt-based waterproof coatings in my country are divided into two categories: hot-melt construction type asphalt waterproof coatings and cold construction type waterproof coatings. Among them, the cold construction type is divided into solvent type asphalt waterproof coating and water emulsion type asphalt waterproof coating. The hot-melt asphalt waterproof coating is boiled on site, and the hot construction method produces a large amount of smoke, which is not only prone to fires and burns, but also has high energy consumption; solvent-based asphalt waterproof coatings have air pollution,...
