Problems solved by technology

Most waterproof coatings use polymer emulsion and cement as the main functional raw materials, use powders of different particle sizes as stable filler powders, and add modified additives to make volatilization and hydration reaction waterproof coatings. Most of these coatings return to thick Faster, can guarantee roller coating construction in the early stage, and can only rely on external water to maintain the construction performance of the product in the later stage, and cannot guarantee the performance and waterproof effect of the product

Abstract

An easy-to-coat flexible waterproof slurry and a preparation method thereof, belonging to the technical field of waterproof coatings, mainly composed of polymer emulsion, defoamer, dispersant, quartz powder, quartz sand, gray cement, and polyvinyl alcohol, Among them, component A is mainly composed of 80-90 parts of polymer emulsion, 1-3 parts of defoamer, 0.3-0.5 parts of dispersant, 0.1-1 part of fungicide; 1-2 parts of antifungal agent, and component B is gray cement 40-60 parts, 30-45 parts of quartz sand, 10-15 parts of quartz powder, 0.02-0.05 parts of polyvinyl alcohol, 0.5-1 part of water reducer. The easy-to-coat flexible waterproof slurry of the invention has excellent construction performance, subsidence resistance performance, bonding strength, waterproof effect and anti-cracking function.

Description

technical field [0001] The invention relates to an easy-to-coat flexible waterproof slurry and a preparation method thereof, belonging to the technical field of waterproof coatings. Background technique [0002] In the field of architectural waterproof coatings, various waterproof coating products with different performances are everywhere, making up for the gaps in waterproof and moisture-proof of different building bases, but waterproof coating products that can not only guarantee the waterproof effect of coatings but also ensure excellent construction performance are not more common. Most waterproof coatings use polymer emulsion and cement as the main functional raw materials, use powders of different particle sizes as stable filler powders, and add modified additives to make volatilization and hydration reaction waterproof coatings. Most of these coatings return to thick It is faster, and the roller coating construction can be guaranteed in the early stage. In the later...
