Abstract

The invention discloses polymer silicate cement waterproof coating and a method for preparing the same. The polymer silicate cement waterproof coating comprises, by weight, 10%-16% of high-polymer emulsified asphalt, 6%-10% of alkoxy silane, 12%-20% of silicate cement, 1.2%-2.8% of hydroxypropyl methyl celluloses, 5%-15% of quartz powder, 2.5%-6.9% of heavy calcium carbonate, 5.5%-9.2% of heavy calcium carbonate polyol, 1.2%-2.6% of coalescing agents and the balance deionized water. The polymer silicate cement waterproof coating and the method have the advantages that the high-polymer emulsified asphalt, the silicate cement, the hydroxypropyl methyl celluloses, the quartz powder, the heavy calcium carbonate and the heavy calcium carbonate polyol are matched with one another according to specific proportions to obtain the polymer silicate cement waterproof coating, accordingly, the polymer silicate cement waterproof coating has a powerful waterproof function and is excellent in ageing resistance, high in adhesive strength, good in constructability and free of toxic and side effects, and materials are good in extensibility and are safe and environmentally friendly.

Description

technical field [0001] The invention relates to a polymer portland cement waterproof coating and a preparation method thereof. Background technique [0002] With the continuous development and refinement of the domestic coatings industry, the market's requirements for special functional coatings are becoming more and more prominent. Among them, the performance requirements for anti-aging, water resistance, acid and alkali corrosion resistance, and flame retardancy are even higher. In order to meet the industry's requirements for waterproof coatings, it is necessary to produce high-performance and widely used waterproof coatings. [0003] Traditional polymer Portland cement-based waterproof materials also have poor water resistance and short service life, and cannot be used for second-level and above waterproof roofs and important waterproof projects. When the acrylate polymer emulsion is used as the liquid material of the polymer Portland cement waterproof coating, there ar...
