Problems solved by technology

[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 poor weather resistance, the coating is not cleaned after being polluted, 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, than the water resistance of traditional wall coating, pollution resistance, aging resistance, anti-ultraviolet, antibacterial and other performance indicators are better, but Its washing resistance is only 11,000 times, and its artificial aging resistance is only 600 hours. In order to further improve the performance of the wall coating, it is necessary to improve the formula of the coating

Embodiment 1

[0031] Embodiment 1: nano interior wall paint (white) composition:

[0032]

[0033] The commercially available nano-silica and nano-titanium dioxide are dispersed in the water-soluble nano-scale silica sol carrier by high-speed shearing, and the materials are added according to the formula, stirred, sanded, emulsified, painted, and filtered. The product of gained is the interior wall paint of white, test result: (1) brush on the surrounding wall of building area 10 square meters, under the irradiation of fluorescent lamp after 72 hours, test with the portable negative ion tester that Japan produces, negative ion concentration reaches 1300pcs / CM 3 (2) The number of times of washing and washing is 32,000 times without showing the bottom; (3) The artificial weathering resistance test: 1,000 hours: (4) The test result of the mold resistance of the paint film: the effect of preventing (anti) mold is remarkable, and the product is stored and painted behind the wall Can effectiv...

Embodiment 2

[0034] Embodiment 2, nano interior wall paint [white] formula composition:

[0035]

[0036] The nano-titanium dioxide and nano-silicon dioxide bought from the market are dispersed in the water-soluble nano-scale silica sol by high-speed shearing, and the materials are added according to the formula, stirred, sanded, emulsified, painted, and filtered. The resulting product is a white interior paint. The test results: (1) Brush on the surrounding walls with a construction area of ​​10 square meters, and after 72 hours, under the irradiation of fluorescent lamps, test with a portable negative ion tester made in Japan, and the negative ion concentration reaches 1800 / CM 3 (2) The number of times of washing and washing is 39,000 times without showing the bottom; (3) The artificial weathering resistance test: 1,000 hours: (4) The test result of the mold resistance of the paint film: the effect of preventing (anti) mold is remarkable, and the product is stored and painted behind t...

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...
