Abstract

The invention relates to an outer wall coating for buildings. The outer wall coating is prepared from the following raw materials in parts by weight: 100 parts of an acrylic resin solution, 15-30 parts of zinc naphthenate, 5-10 parts of ultramarine, 20-30 parts of xylene, 15-25 parts of talcum powder, 15-35 parts of glycerol ester of rosin, 5-15 parts of light calcium carbonate, 25-35 parts of a thickening agent, 35-45 parts of titanium dioxide, 50-60 parts of rosin modified phenolic resin, 10-30 parts of hydroxyethyl cellulose, 1-10 parts of fungicide, 5-15 parts of propylene glycol and 10-20 parts of methylbenzene. The outer wall coating for buildings is free of caking, is in a uniform state when being stirred, free of phenomenon such as foaming or powder dropping after the outer wall coating is soaked in water for 15-30 days, smooth in coating surface, free of abnormity when being soaked in alkali water for 15-30 days, long in storage time and can be widely produced and constantly replace existing materials, the surface drying time is 1-2 hours, and the coating film is resistant to brushing and washing for 1200-1800 times.

Description

technical field [0001] The application belongs to the field of coatings, in particular to an exterior wall coating for buildings. Background technique [0002] Paint, traditionally known as paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding Corresponding additives, viscous liquid prepared with organic solvent or talcum powder. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a paint film or a coating." The material coated on the sur...
