Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly waterproof coating and a preparation method thereof. Background technique [0002] In recent years, with the continuous development and refinement of the domestic coatings industry, the market's requirements for special functional coatings have become more and more prominent. Waterproof coatings are one of these special functional coatings with a relatively large usage and market demand. , due to its excellent waterproof performance and easy construction performance, it is widely used in waterproof projects in the construction industry. [0003] The waterproof coating is painted on the surface of the building, and a thin film is formed by the volatilization of solvent or water or the chemical reaction of the two components, so that the surface of the building is isolated from water, thereby playing the role of impermeability and waterproofing, and at ...
