Abstract

The invention relates to an internal wall paint which is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl alcohol, 20-40 parts of lithopone, 40-55 parts of sodium silicate, 40-60 parts of ground calcium carbonate, 80-100 parts of water, 30-40 parts of siliceous limestone powder, 0.1-0.5 part of polyoxyethylene, 8-10 parts of glycerol abietin, 0.1-0.3 part of plasticizer, 0.1-0.3 part of lead acetate, 3-13 parts of tinting pigment, 30-50 parts of sodium silicate, 5-40 parts of talcum powder and 0.3-0.5 part of castor oil. The solid content of the product is 30-40%, and the fineness is 40-60 mu m; the surface drying time is 0.5-1 hour, and the paint does not have the phenomenon of blistering or shedding after being immersed in water for 10 days; the paint has favorable heat resistance, and does not have the phenomenon of sticking or cracking at 90 DEG C for 5 hours; and the product has the advantages of favorable low-temperature resistance (not frozen at -5 DEG C), favorable scrub resistance, favorable stability and smooth and flat coated film, and can be widely produced and used instead of the existing materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to an interior wall coating. Background technique [0002] Coatings belong to organic chemical polymer materials, and the formed coating film belongs to the type of polymer compounds. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. Paint is a material that can be well bonded to the base material and form a complete and tough protective film on the surface of an object, called a paint. Paint and paint are the same concept. Paint is a customary name that people have used for a long time. After it was introduced into my country, it has been used in the construction industry. The role of coatings can be summarized into three aspects: protection, decoration, and special functions. The general comp...
