Embodiment Construction

[0004] (one)

[0005] 1. Add 100 parts of water and 4-6 parts of ethylene glycol into the mixer, start stirring, add 1 part of dispersant, 1~2 hydroxyethyl cellulose, 70~80 parts of titanium dioxide, 6~ 8 parts of kaolin, 80 to 90 parts of lithopone, 50 to 60 parts of talcum powder, 1 part of nano-scale calcium carbonate, 2 to 3 parts of attapulgite, 1 part of wetting agent, stir well and add in, continue stirring to make the substance Mix well.

[0006] 2. Inject the above-mentioned uniformly stirred slurry into a sand mill and grind it to a certain fineness, then pour it into a paint mixing tank, add 120-130 parts of styrene-acrylic emulsion and 2 parts of defoamer and stir evenly, and then slowly add 10 parts Coating aid, 2 parts of antifungal agent, 1.5 parts of preservative and 2 to 3 parts of super absorbent resin, and then add 8 to 10 parts of anatase TiO 2 And antibacterial powder, continue to stir, finally add 2 parts of thickener and 1 part of amine neutralizer, fi...

Abstract

The invention discloses a novel environmentally-friendly nanometer antibacterial latex paint. A process formula comprises 0.5-1 percent by weight of anatase TiO2, 0.5-1 percent by weight of antibacterial powder and 0.2-0.4 percent of nanometer calcium carbonate besides components including water, an emulsion, a pigment, a filler and various aids in the conventional latex paint. A production process comprises the following steps of: adding water into a stirrer; adding a dispersant, a wetting agent, diatomite, a pigment-filler, attapulgite and a part of antifoaming agent in sequence in a stirring process; stirring uniformly, and injecting into a sand mill for milling to certain fineness; pouring into a thinning tank; adding an emulsion and the remaining antifoaming agent, and stirring uniformly; slowly adding a film forming aid, a dry film mold preventive, a preservative and super absorbent resin, and fully stirring; adding anatase TiO2 and antibacterial powder; adjusting the latex paint to appropriate viscosity; and stirring uniformly, filtering and packaging. The latex paint has the functions of resisting bacteria, purifying air, and the like.

Description

technical field [0001] The invention relates to decorative material latex paint in the construction industry, in particular to a novel environment-friendly nano-antibacterial latex paint, in particular to the preparation and application of the latex paint, and the development and application of nano-antibacterial materials. Background technique [0002] In decoration, as long as it involves wall problems, everyone cannot do without latex paint. People's pursuit of a healthy and clean ecological living environment is becoming more and more intense. Panjin Omar Green Industry Co., Ltd. applied for it in December 2002 Although a kind of environment-friendly latex paint (CN1415678A) has realized anti-aging to a certain extent, anti-oil stain, alkali-resistant compactness is stronger, and for preventing and treating various germs and harmful gases. Products with antibacterial function are more and more favored by people at present. In response to this situation, we have develope...
