Abstract

The invention belongs to the technical field of waterproof materials, and provides a polymer cement waterproof coating and a preparation method thereof. The coating is composed of the following components, in parts by weight: 16-25 parts of cement, 13-20 parts of heavy calcium carbonate powder, 7-15 parts of quartz powder, 33-45 parts of a styrene-acrylic emulsion, 4-10 parts of water, 3-7 parts of cationic starch, 4.5-6.3 parts of a compatibilizer, 0.5-1 part of poly(N-isopropylacrylamide), 0.05-0.5 part of polydimethylsiloxane, 1.5-3 parts of a retarder, 0.3-1.2 parts of a plasticizer, and 0.01-0.1 part of a preservative, wherein the compatibilizer is a mixture of sodium dilauramidoglutamide lysine, poloxamer and polyethylene glycol in a mass ratio of 1:5:3, and the retarder is a mixture of carboxymethyl chitosan and sucrose stearate in a mass ratio of 2:1. The preparation method comprises the steps of adding a dry mixed material into a half volume of a mixed liquid, performing ultrasonic dispersion, after the mixture is uniformly mixed, adding the remaining volume of the mixed liquid, and performing uniform mixing. Through the above technical solution provided by the in vention, the problem that tensile strength and elongation at break of a polymer cement waterproof coating in the prior art are not high 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...
