Inorganic dry powder coating and production technology thereof

Abstract

The invention discloses an inorganic dry powder coating and a production technology thereof, and belongs to the field of building decoration materials. The problem that existing indoor interior wall coatings contain heavy metal harmful substances such as bactericides, mildew inhibitors, deodorants, film forming aids and flavors and the problem that emulsions contain volatile harmful substances aresolved. The raw materials for composing the inorganic dry powder coating include heavy calcium, kaolin, quartz powder, talcum powder, titanium dioxide, barium sulfate, a defoamer, a dispersant, a redispersible latex powder, white cement, a suspending agent, a water repellent agent and hydroxyethyl cellulose. The invention also discloses the production technology and a using method of the inorganic dry powder coating. The inorganic dry powder coating is free from all above harmful substances, replacement with an ore powder fundamentally solves the environmental protection problem, and the inorganic dry powder coating is obtained by physical stirring processing, is convenient to store, is simple to construct, can be applied in a spray coating or roller coating manner, can be constructed after being directly mixed with water and stirred, has the advantages of quickness in decomposition, non-agglomeration, washability, good adhesion, good alkali resistance and good anti-oxidation property, and is suitable for being used an interior or exterior wall coating.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to an inorganic dry powder coating and a production process thereof. Background technique [0002] With the improvement of social and economic conditions and the improvement of living environment, people pay more and more attention to decoration, but many materials contain harmful substances, which continuously pollute our living space, and many diseases are caused by decoration, such as leukemia, Lung cancer, fetal malformations, respiratory diseases, etc. are endangering our health all the time. The country has gradually increased the main indicators of decorative materials, but with the gradual increase in the use of decorative materials, it is still difficult to control all environmental protection indicators when added up. , can not avoid or exceed the standard, causing serious serious indoor air pollution.

Problems solved by technology

[0002] With the improvement of social and economic conditions and the improvement of living environment, people pay more and more attention to decoration, but many materials contain harmful substances, which continuously pollute our living space, and many diseases are caused by decoration, such as leukemia, Lung cancer, fetal malformations, respiratory diseases, etc. are endangering our health all the time. The country has gradually increased the main indicators of decorative materials, but with the gradual increase in the use of decorative materials, it is still difficult to control all environmental protection indicators when added up. , can not be avoided or exceed the standard, causing serious serious indoor air pollution

The existing indoor wall materials are mainly decorated with wallpaper, wall covering, latex paint and other materials. It is difficult to achieve the fire protection index of wall covering, and the wall is also sealed by wallpaper and latex paint. If it is affected by external humidity, it is easy to appear large Bulge, peeling, peeling, etc.
