Abstract

The invention discloses a low-cost silicasol-type interior wall coating. The low-cost silicasol-type interior wall coating consists of the following components in percentage by weight: 6 to 8 percent of styrene-acrylic emulsion, 10 to 14 percent of silicasol, 2 to 6 percent of bentonite, 35 to 45 percent of titanium dioxide and wollastonite powder, 6 to 8 percent of hydroxyethyl cellulose, 6 to 8 percent of dispersing agent, 3 to 5 percent of defoaming agent, 0.05 to 0.1 percent of multi-functional aid, 3 to 8 percent of Texanol lipidol, 0.15 to 0.25 percent of antiseptic and antimildew agent, 1 to 2 percent of thickening agent and 15 to 25 percent of water. The coating provided by the invention has the hardness of inorganic coatings and certain flexibility, keeps the quick dryness and easy painting performance of organic coatings, displays the advantages of inorganic coatings and organic coatings and contributes to the performance improvement of coatings as well as cost reduction.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a low-cost silica sol type interior wall paint. Background technique [0002] At present, silica sol coating is one of the most promising environmental protection building materials. Silica sol is a dispersion in water with SiO2 as the basic unit. Its molecular formula is H2SiO3. The micellar particles are fine, and the particle size range is generally 5-40nm. . During gelation, SiO2 has high activity and is easy to bond the powder particles in the paint, so one of the most prominent advantages of its use in paint is no back-solubility and good water resistance. When silica sol is used alone, there are often fatal defects such as cracks and internal micropores in the film formed by curing at room temperature, so it is rarely used alone to prepare coatings. At the same time, the price of silica sol is relatively expensive, and the cost performance is relatively low. ...
