Abstract

The invention discloses a polymer cement waterproof coating and a preparation method thereof. The polymer cement waterproof coating comprises liquid materials and powder materials, wherein the liquidmaterials comprise the following components in parts by weight: 10-15 parts of EVA emulsion, 10-15 parts of acrylate polymer emulsion, 0.05-0.1 part of a dispersant 5040, 0.8-1 part of ethylene glycolmonobutyl ether and 0.1-0.3 part of polymethyl silicone resin, 0.06-0.12 part of polyoxypropylene oxyethylene glyceryl ether, 0.2-0.4 part of an anti-aging agent, 0.2-0.4 part of a cross-linking agent, 0.1-0.2 part of a bactericide and 0.1-0.2 part of a dry film mildew inhibitor; the powder comprises the following components in parts by weight: 8-10 parts of Portland cement, 4-6 parts of heavy calcium carbonate, 4-6 parts of quartz powder, 0.5-1.5 parts of wollastonite, 0.5-0.8 part of montmorillonite, 0.1-0.2 part of nano titanium dioxide, 0.04-0.08 part of sodium hexametaphosphate and 0.4-0.6 part of chlorinated paraffin. The polymer cement-based waterproof coating has the advantages that the polymer cement-based waterproof coating has good durability.

Description

Technical field [0001] The invention relates to architectural coatings, in particular to a polymer cement waterproof coating and a preparation method thereof. Background technique [0002] Polymer cement waterproof coating, also known as JS waterproof coating, is made from polymer emulsions such as acrylic ester, ethylene-vinyl acetate and cement as the main raw materials, and is formulated by adding fillers and other additives. After water volatilization and cement hydration reaction A two-component water-based waterproof coating that cures into a film. [0003] The Chinese patent with publication number CN106118481A discloses a self-healing polymer cement waterproof coating and a preparation method thereof. The waterproof coating is a two-component coating, and the liquid material A is composed of components in weight percentages: polymer emulsion 70-80%, hydroxyethyl cellulose 0.5-1%, defoamer 3-5%, water residue Quantity; Powder B is composed of components in percentage by we...
