Abstract

The invention discloses a polyvinyl alcohol washable interior wall coating for a building. The coating comprises the following components in parts by weight: 100 parts of polyvinyl alcohol, 20-30 parts of polysiloxane, 20-40 parts of formaldehyde, 10-20 parts of chloroethylene, 80-100 parts of water, 5-15 parts of vinyl acetate, 30-40 parts of limestone powder, 15-20 parts of styrene, 25-35 parts of melamine, 15-25 parts of dimethylethanolamine, 60-70 parts of extender pigment, 40-50 parts of a defoamer, 30-50 parts of talcum powder and 45-55 parts of maleic anhydride. According to the coating, the solid content is 30%-40% and the fineness is 60-80 microns; the surface drying time is 0.5-0.8 hour and no bubble and falling phenomena are caused after the coating is soaked in water for 24 hours; the heat resistance is good and no tacky and cracking phenomena are caused after the coating is heated at 90 DEG C for 5 hours; the coating can be washed for 300-500 times, is good in washability and stability, can be produced on a large scale, and continuously replaces an existing material.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a polyvinyl alcohol scrub-resistant interior wall coating for buildings. Background technique [0002] Paint, traditionally called 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 The corresponding additives are viscous liquids prepared with organic solvents or water. 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....
