Abstract

The invention discloses an inorganic dry powder sand textured architectural coating which comprises the components of colored sand, colored stone flour, alkali metal silicate, a curing agent and organic redispersible latex powder. The bonded substance of the inorganic dry powder sand textured architectural coating provided in the invention is transparent, and the color of the colored sand and the colored stone flour is fully showed; therefore, the inorganic dry powder sand textured architectural coating has a good texture effect similar to stone, and fire resistance of the coating satisfies the A grade of PRC GB50222 standard, i.e., the coating is an incombustible inorganic dry powder sand textured coating.

Description

technical field [0001] The invention relates to an architectural coating, in particular to an inorganic dry powder sand wall architectural coating. Background technique [0002] Buildings decorated with natural stone are gorgeous, noble and of high quality. However, due to the high price of natural stone and the inconvenience of construction, a kind of architectural coating that simulates stone - sand wall coating, also known as real stone paint or real stone paint, has been developed on the market. Imitation stone paint, the paint is sprayed directly, and its decorative effect has the texture and color of natural stone. The buildings decorated with real stone paint not only have the luxurious appearance and hardness of stone, but also have artistic effects such as elegance, nobility, and strong three-dimensional sense. It is an ideal material to replace natural stone finishes. [0003] The existing sand wall paint is generally made of synthetic resin emulsion, natural colo...
