Abstract

The invention relates to an external wall natural stone paint suitable for construction in a low-temperature high-humidity environment. The invention is characterized in that the paint is mainly composed of the following components in percentage by mass: 70-80% of colored sand, 12-15% of silicon-modified styrene-acrylic emulsion 8666, 0.6-0.8% of film forming aid, 2.0-3.0% of silica sol, 0.1-0.15% of thickener and the balance of conventional aid, totaling 100%. The film forming aid is mainly compounded from Texanol ester alcohol, ethylene glycol monobutyl ether and benzyl alcohol. The thickener is compounded from a polyurethane thickener and an alkali thickener. The natural stone paint can achieve the constructability of the normal temperature environment in the low-temperature high-humidity environment.

Description

technical field [0001] The invention relates to an exterior wall paint, in particular to a real stone paint for an exterior wall, in particular to a real stone paint for an exterior wall suitable for construction in a low-temperature and high-humidity environment. Background technique [0002] The real stone paint for exterior walls is made of natural granite and other natural gravel and powder as main raw materials, synthetic resin emulsion as adhesive, and supplemented by various additives. Real stone paint for exterior walls has the rich texture and three-dimensionality of natural stone, as well as a solemn and harmonious aesthetic feeling; moreover, compared with exterior wall bricks and dry-hanging granite, it is more economical and applicable at lower prices. The decorative effect of real stone paint on the exterior wall is comparable to that of stone, and it is more suitable for shaping various artistic shapes than stone. Its durability and impermeability are longer, ...
