Abstract

The invention discloses an inner wall coating. The inner wall coating is prepared by the following steps of (1) weighing bentonite powder, silicon propylene emulsion, a casein modified sol solution, polyvinyl alcohol, wollastonite powder, deionized water, sodium silicate, calcium stearate, dibutyl phthalate and gelatin; (2) adding the polyvinyl alcohol, the deionized water and the sodium silicateinto a reaction kettle with a stirrer and a thermometer, heating, stirring, adding the dibutyl phthalate and the gelatin, cooling, and continuing to stir; (3) heating, adding the remaining raw materials, stirring, grinding by a grinding machine, cooling, filtering, and inspecting until the material is qualified. The inner wall coating has the advantages that a coating film is smooth and flat, thepowder falling is avoided, the brush trace is avoided, the caking and settling of the coating are avoided, the brushing is easy, the sagging is avoided, and the adhesion force is 100%; the water-resistant property lasts for 20 to 40d without foaming, and the alkaline-resistant property lasts for 10 to 30d without wrinkle; the combustion, poison and odor are avoided, the scrubbing-resistant property is 5000 times without primer exposing, and the abrasion-resistant property is good.

Description

technical field [0001] The invention relates to the field of environmental protection 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. [0003] The function of coating is decoration and protection, protecting the surface of the coated object, preventing the erosion of light, oxygen, chemical substances, solvents, etc. from the outside, and improving the service life of the coated object; coating on the surface of the material can change its color , pattern, luster, texture, etc., to improve the aesthetic value of the object. [0004] There are many kinds of interior wall paint...
