Abstract

An interior wall paint for construction is composed of the following raw materials in parts by weight: 100 parts of polyvinyl alcohol resin, 20 to 30 parts of rosin, 45 to 55 parts of soluble glass, 30 to 40 parts of turpentine, 80 to 100 parts of water, 10 to 20 parts of ethanol, 20 to 40 parts of coloring pigment, 5 to 10 parts of wax, 40 to 50 parts of lithopone, 5 to 10 parts of tetrahydrofuran, 60 to 80 parts of extender pigment, 1 part of silicon dioxide, 40 to 60 parts of talcum powder, and 50 to 60 parts of toluene. The solid content of the paint is 30 to 40%, the fineness is 60 to 80 [mu]m, and the surface drying time is 0.1 to 0.8 hour. The paint does not have the phenomenon of foaming or falling off after being soaked in water for 24 hours. The heat resistant property of the paint is good, and the paint does not have the phenomenon of clamminess and cracking at a temperature of 90 DEG C for 5 hours. The paint does not have the phenomenon of fading and chalking after being irradiated by ultraviolet lights for 100 hours, has a good scrubbing resistant property and stability, can be produced in large-scale, and is capable of replacing the conventional materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to an 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." The material coated on the surf...
