Abstract

The present invention discloses a preparation method of modifying acrylic acid waterproof dope for house face; 0.01 portion of sodium hexametahposphate is added into water for milling. 0.2 portion of sericite powder, 0.1 portion of silicon lime powder, 0.1 portion of titanium powder are added to be milled; after grinded for two times, 0.2 portion of pure acrylic acid ester latex, 0.1 portion of watercraft polyurethane latex, 0.2 portion of organic silicon latex, 0.1 portion of ethylene-polyvingl acetate emulsion, 0.01 portion of glycol, 0.01 portion of dibutyl phthalate and 0.001 portion of sodium pentachlorophenate are added for milling. And finally, 0.01 portion of organic silicon defoamer agent is added to be milled so as to obtain the present invention. The present invention has the advantages of innocuous, inodorous and non-pollution. The present invention has water-hating performance. The present invention can bear or endure the irradiation of ultraviolet radiation. In addition, the present invention is characterized in anti-aging, much stronger adhesion intension, waterproof, seepy-resisting, heat-resisting and cold-resisting. The present invention has much better extending ability; the present invention has the advantages of cool construction and can be coated directly.

Description

technical field [0001] The invention relates to a preparation method of a modified acrylic roof waterproof paint. Background technique [0002] At present, polyurethane waterproof coatings for roofing are expensive, toxic and pollute the environment. Waste rubber-modified asphalt is of poor quality and has great production safety hazards; acrylic emulsion has low tensile strength, poor low temperature resistance and poor weather resistance. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defect, a kind of preparation method of modified acrylic roof waterproof paint is provided. [0004] The technical scheme of the present invention is: a method for preparing a modified acrylic roof waterproof coating, characterized in that: take water and add 0.01 part of sodium hexametaphosphate, stir, add 0.2 part of sericite powder, 0.1 part of wollastonite powder, and 0.1 part of titanium dioxide 0.2 parts of pure acrylate emulsio...
