Abstract

The invention belongs to the technical field, and proposes a polymer cement waterproof coating and a preparation method thereof, which consists of the following components in parts by weight: 16-25 parts of cement, 13-20 parts of heavy calcium powder, 7-15 parts of quartz powder, 33-45 parts of styrene-acrylic emulsion, 4-10 parts of water, 3-7 parts of cationic starch, 4.5-6.3 parts of compatibilizer, 0.5-1 part of poly-N-isopropylacrylamide, 0.05 parts of polydimethylsiloxane ~0.5 parts, retarder 1.5~3 parts, plasticizer 0.3~1.2 parts, preservative 0.01~0.1 parts, compatibilizer is bis(lauramide glutamine) sodium lysine, poloxamer and poly The mass ratio of ethylene glycol is a mixture of 1:5:3, and the retarder is a mixture of carboxymethyl chitosan and sucrose stearate with a mass ratio of 2:1. Add half the volume of the mixed solution to ultrasonic dispersion and mix evenly, then add the remaining volume of the mixed solution and mix evenly. Through the above technical solution, the problem of low tensile strength and elongation at break of the polymer cement waterproof coating in the prior art is solved.

Description

technical field [0001] The invention belongs to the technical field of waterproof materials, and relates to a polymer cement waterproof coating and a preparation method thereof. Background technique [0002] Polymer Cement Waterproof Coating (JS Waterproof Coating) is a liquid material and matching powder formed by the optimized combination of synthetic polymer emulsion (such as polyacrylate, polyvinyl acetate, styrene-butadiene rubber emulsion, etc.) and various additives. It is a two-component waterproof coating composed of special cement, quartz powder and various additives. The two components are mixed on site to form a uniform and fine slurry, which is painted or sprayed on the surface of the substrate. After curing, it can form a flexible , High-strength waterproof coating film, using water as the carrier, overcomes the disadvantages of asphalt, tar, and organic solvent-based waterproof materials polluting the environment. It is a new green and environmentally friendly...
