Problems solved by technology

The disadvantage of this invention is that the alkali resistance of the selected emulsifier is not strong, and the glass temperature of the polymer produced is relatively high, so the chemical stability of the waterproof coating and the retardation to cement are all relatively poor.

Abstract

The invention discloses a polymer cement waterproof coating acrylic emulsion comprising the components in percentage by weight in the formula: 10-20 percent of styrene, 1-10 percent of methyl methacrylate, 30-45 percent of butyl acrylate, 0.1-0.5 percent of methacrylic acid, 1-3 percent of ethylene glycol dimethacrylate, 1-3 percent of emulsifier, 0.3-0.8 percent of persulfate and the balanced of water. Compared with the prior art, the invention has more excellent chemical stability and crack resistance property, good retarding property when being mixed with cement and convenient site construction.

Description

technical field [0001] The present invention relates to architectural coatings, in particular to polymer emulsions in waterproof coatings. Background technique [0002] Polymer cement waterproof coating (referred to as JS waterproof coating) is a two-component water-based architectural waterproof coating prepared by adding polymer emulsion such as acrylate and cement as the main raw materials, and adding other admixtures. Since this kind of coating is composed of two components of "polymer emulsion-cement", it has the characteristics of "combining rigidity and softness". Advantages of base bonding. The ratio of polymer emulsion to cement can be adjusted to meet the requirements of different projects on flexibility and strength, and the construction method is convenient. In such two-component waterproof coatings, the chemical stability of the polymer emulsion components is the key to the quality of waterproofing projects. Chinese Invention Patent No. ZL01127087.X discloses...
