Abstract

The invention discloses an environment-friendly interior wall coating and a preparation method thereof. The environment-friendly interior wall coating comprises the components of 6-11 parts of modified silica sol, 30-47 parts of modified acrylate emulsion, 2-3 parts of talcum powder, 3-5 parts of anatase titanium dioxide, 3-5 parts of wollastonite powder, 1.8-2.5 parts of white carbon black, 4.8-7.2 parts of bamboo fiber powder, 5-8 parts of shell powder, 0.05-0.06 part of a wetting agent, 0.08-0.13 part of a film-forming agent, 0.1-0.15 part of a dispersing agent, 0.02-0.1 part of a defoamingagent, 0.1-0.5 part of a thickening agent and 7-12 parts of water in parts by weight. The environment-friendly interior wall coating disclosed by the invention has the advantages that the formula issimple; a natural and environmentally friendly function, a radiation resistant function, a mildew proofing and bacteriostatic function, a breathable and moisture-absorbent function and a stain-resistant function are realized; the adhesion force of a dried coating film is good, and the dried coating film can eliminate odor and regulate air humidity; in the preparation method, the production condition is simple, and the raw material loss is less; and hydroxyethyl cellulose is not needed in the preparation process.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly interior wall coating and a preparation method thereof. Background technique [0002] Interior wall paint is a viscous suspension made by stirring and grinding pigments, fillers, additives and emulsions. The coating film formed on the surface of the wall can not only protect the wall but also protect the wall. to the decorative effect. With the continuous improvement of the national economy and people's living standards, and the continuous development of the housing industry and decoration industry, architectural coatings, especially interior wall coatings, have also had a broad development space. Under the premise of environmental protection, interior wall coatings are developing towards functional coatings. The development trend of interior wall coatings is low odor, clean aldehyde, scrub resistance, antibacterial, humidity control, etc. In recent year...
