Preparation method of building coating

Abstract

The invention discloses a preparation method of a building coating. The building coating has good polishability, good adhesiveness and a good waterproof property, and is composed of boric acid, a styrene acrylic emulsion, benzyl bromoacetate, magnesium oxide, polyvinyl alcohol, polyurethane resin, titanium dioxide, a film forming assistant, sodium hexametaphosphate, a dispersant, a thickening agent, heavy-calcium-and-silicon pulverized lime, talcum powder and an antifoaming agent. The building coating adopting an efficient antiseptic can effectively inhibit Aspergillus niger, Aspergillus flavus, Aspergillus versicolor and the like. The coating has the advantages of good mildew resistance, harmlessness to human bodies, low cost, extremely strong adhesion, extremely strong water and ultraviolet resistances, and no peeling, shedding or color change after long-term use in wet environment.

Description

[0001] technical field [0002] The invention belongs to the technical field of coatings, and in particular relates to a configuration method of coatings with strong adhesion for interior and exterior walls of buildings. [0003] Background technique [0004] Paint, also known as paint, refers to a class of liquid or solid materials that can form a thin film on the surface of an object under certain conditions to protect, decorate or other special functions. Because most of the early paints used vegetable oil as the main raw material, they are also called paints. Now synthetic resins have mostly or completely replaced vegetable oils, so they are called paints. There are three main functions of coatings: protection, decoration, and concealing the defects of products to enhance the value of products. [0005] At present, the antibacterial agents used in architectural interior wall coatings are mainly inorganic salts such as mercury salts, which will cause certain harm to ...
