Problems solved by technology

However, many advantages of polymer cement waterproof coatings (also known as JS coatings) have not been fully discovered. Currently, the commercially available JS coatings have a large poly-ash ratio (large amount of polymer), limited elongation rate, poor water resistance, and high water absorption. , After long-term immersion in water, the softening strength obviously decreases. After two or three years on the roof, some products obviously harden and elongation decreases. This solves the problem that polymer cement waterproof coatings (JS coatings) can better play the waterproof role and are widely used in waterproofing in engineering construction. Corrosion resistance is a very important issue

Abstract

The invention discloses a waterproof paint composition of outer wall polymer cement, which comprises the following components by part by weight: 100-150 parts of elastic polyacrylic emulsion, 80-120 parts of white cement, 20-40 parts of titanium dioxide, 20-40 parts of ground limestone, 2-4 parts of DBP (dibutyl phthalate), 2-4 parts of dipropylene glycol methyl ether, 0.5-1.5 parts of sodium aluminate, 2-4 parts of water reducer, 2-4 parts of defoaming agent, and 40-80 parts of aseptic barium-zinc latexes. The waterproof paint composition improves the stability, water-resistance performance and impermeability of mortar, and has excellent germicidal effect, therefore, the coating is not invaded by bacterium; and simultaneously, the coating has excellent self closing effect, thus having important action of prolonging the service life.

Description

technical field [0001] The invention relates to an exterior wall polymer cement waterproof coating composition. Background technique [0002] With the rapid development of the national economy, my country's engineering construction is also booming, especially the construction of various projects such as housing, sports facilities, and road traffic, which provide material conditions for improving people's living standards.
