Abstract

The invention discloses an environment-friendly polymer cement waterproof paint. The paint is composed of a component A and a component B, wherein the component A is environment-friendly polymer emulsion, which comprises the following raw materials in parts by weight: 85 to 95 parts of vinyl acetate-ethylene emulsion (VAE emulsion), 1 to 3 parts of emulsion antifoaming agent, 5 to 10 parts of deionized water, and 0 to 0.1 part of hydroxyethyl cellulose ether; and the B component comprises the following raw materials in parts by weight: 30 to 40 parts of cement, 40 to 50 parts of wollastonite needle-like powder, 20 to 30 parts of quartz powder, 3 to 8 parts of talcum powder, and 0.1 to 0.4 part of gas-phase silicon dioxide. VAE emulsion with protective polyvinyl alcohol colloid is taken as the main material, no nonvolatile additive other than antifoaming agent such as surfactant, plasticizer, or the like is added, and the waterproof paint does not contain any environment harmful substance and can fully meet the related product standards.

Description

technical field [0001] The invention belongs to the technical field of waterproof coatings, in particular to an environment-friendly polymer cement waterproof coating. Background technique [0002] 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 the same time using the coating film Its own strength and elasticity prevent the damage of the external environment and the cracks of grassroots activities. The process formula of the existing waterproof coating, firstly, the selected main material is mostly a polymer emulsion emulsified by surfactants, and secondly, more plasticizers, dispersants and various surfactants are added to meet the elasticity, leveling, "Construction performance" such as viscosity, stability, and ...
