Abstract

The invention discloses an inorganic dry powder solid color prime coat and application thereof. The inorganic dry powder solid color prime coat comprises the following components: an inorganic gelation system and a binding agent composed of redispersable gelatin powder, pigment, filler and additive, wherein the inorganic gelation system is selected from any one or a mixture of several of silicate, aluminate, calcium carbonate and calcium sulfate. The solid color prime coat can be used for indoor wall decoration. The inorganic dry powder solid color prime coat can be applied to the building by adding water and uniformly mixing in site under a single-component dry powder state, and has good tinting strength, closure, binding power and stability through test detection, and has good covering power and rubbing property. The defects that the dry powder coat for indoor wall is bad in adhesive force and the color is single can be overcome, and meanwhile, harmful substances such as VOC (volatile organic compound) or heavy metal cannot be produced; and the inorganic dry powder solid color prime coat is a novel, environment-friendly and stable inorganic dry powder solid color prime coat with excellent effect.

Description

technical field [0001] The invention relates to an inorganic primer, in particular to an inorganic dry powder solid-color primer with good sandability, hiding power and storage stability. Background technique [0002] Architectural coatings mainly refer to coatings used for building exterior walls, interior walls, ceilings, floors, etc., with functions of decoration, protection and habitability improvement. The proportions of various functions vary depending on the purpose of use. Among them, the decorative function is the function of improving the appearance value of the building by beautifying it. It mainly includes the concept design of plane color, pattern and gloss and the concept design of three-dimensional pattern; the protection function refers to the function of protecting the building from the influence and damage of the environment, such as mildew resistance, fire prevention, heat insulation, corrosion resistance, etc. Special function; The function of improveme...
