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.
