Abstract

The invention relates to the technical field of coatings, and particularly discloses a waterborne polymer cement-based waterproof coating and a preparation method thereof. The waterborne polymer cement-based waterproof coating is prepared from a liquid material and a powder material in a mass ratio of 1 to (3 to 4), wherein the liquid material is prepared from fluorine-carbon emulsion, titanium dioxide, a filming assistant, a dispersing agent, a defoaming agent, a preservative, an ultraviolet absorbent, a thickening agent and water; the powder material is prepared from cement, quartz sand, ground calcium carbonate, cellulose ether, a water reducer and polypropylene fiber. The waterborne polymer cement-based waterproof coating has the advantages of high strength, superior waterproofness, no detection of volatile organic compounds, formaldehyde and heavy metals, and environmental friendliness.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an aqueous polymer cement-based waterproof coating and a preparation method thereof. Background technique [0002] With the improvement of people's requirements for the quality of construction projects and the functions of building use, the waterproofing of walls, waterproofing of wet interfaces, and waterproofing of basements have attracted more and more attention and attention in the construction industry. In the traditional waterproof concept, people often use flexible waterproof materials such as coils, sheets, and coatings as independent waterproof materials in engineering. These flexible waterproof materials have strong ability to adapt to the deformation of the base layer and are convenient for large-scale construction, but they have high requirements for the dryness of the base layer, generally requiring a moisture content of less than 9%, which is suitable for undergrou...
