Abstract

The invention relates to a nano interior wall coating; the composition by the weight percent is as follows: 35 percent to 45 percent of film-forming material, 28 percent to 42 percent of pigment and filler, 4 percent to 7 percent of assistant, 0.6 percent to 1.2 percent of nano powdery material, 1.0 percent to 2.0 percent of water-soluble nano silica sol, and 10 percent to 30 percent of deionized water. The film-forming material can be styrene-acrylic latex or acrylic latex; the pigment and filler is one or more than one type among rutile titanium dioxide powder, calcined kaolin, heavy calcium carbonate and super-fine aluminum silicate; the assistant comprises one or more than one type among dispersant, wetting agent, foam killer, preservative, thickener, anti-freezing agent, ph regulator and film-forming assistant. The coating of the invention can continuously release negative ions under the radiation of a fluorescent lamp, and can effectively degrade the dissociative TVOC and formaldehyde content in the air; the washing resistant times reaches 20000 to 50000 times, and the manual aging resistance reaches more than 1000 hours. In addition, the coating saves the consumption of nano powdery material and reduces the production cost.

Description

technical field

[0001] The invention relates to a coating, in particular to a water-based interior wall coating with nanometer materials. Background technique

[0002] Wall coatings are popular because of their low toxicity, ease of use, and low price. However, currently commercially available wall coatings, such as latex paint [Nippon Paint, etc.], have short service life, are not resistant to washing, and are resistant to pollution. And weather resistance is poor, the coating is not cleaned after being contaminated, and the coating is prone to aging, yellowing, wrinkling, peeling and other problems. CN1385483A discloses a kind of modified coating of nanometer interior and exterior walls, after it has adopted nanometer material, it is better than various performance indexes such as water resistance, pollution resistance, aging resistance, anti-ultraviolet, antibacterial property of traditional wall coating, but Its washing resistance is only 11,000 times, and its artificia...
