Embodiment 1

[0022] First, add 18.0 parts (parts by mass, the same below) of deionized water, 0.6 parts of wetting and dispersing agent, 2.0 parts of nano-silica powder, 20.0 parts of titanium dioxide, 20.0 parts of precipitated barium sulfate, and 10.0 parts of ultrafine talc in the container Powder and 0.1 part of defoamer, mixed evenly at high speed, then grinded in a sand mill until the fineness is less than 50 microns, then added 35.0 parts of modified acrylic emulsion, 0.1 part of defoamer, 0.3 parts of thickener, 0.2 parts of leveling agent part, 0.3 part of the composite slurry, and adjust the pH value to 8-9, and the finished product can be obtained after stirring evenly. The product quality is excellent, and the performance test results are shown in Table 2.

Embodiment 2

[0024] The preparation method is the same as in Example 1, and its components (parts by mass) are: 24.0 deionized water, 0.8 wetting and dispersing agent, 1.0 nanometer silicon dioxide powder, 10.0 titanium dioxide, 30.0 precipitated barium sulfate, 15.0 ultrafine talcum powder , defoamer 0.2, modified acrylic emulsion 25.0, thickener 0.2, leveling agent 0.2, composite slurry 0.1. The cost of the coating is relatively low, and the properties of the coating are good after testing, and the properties of the coating are shown in Table 2.

[0025] Test items

[0026] As can be seen from table 2 test results, interior wall latex paint of the present invention (embodiment 1 and 2), its film performance (water resistance, scrub resistance) is better than the standard of national excellent product and has good antibacterial property, Anti-mildew, anti-corrosion and the function of removing formaldehyde and toluene. The VOC content of the paint is lower than 5g / l, which is ...

Abstract

The invention relate to a nm material modified latex coating for inside wall with environmental protection,comprises of the following components:water 18-24,dispersant 0.4-1.0;nm silicon dioxide powder 1.0-3.0;deposit barium sulfate 20-30;talcum powder 10-15;titanium dioxide 10-20;antifoaming agent 0.1-0.2;modified crylic acid 25-35;zinc oxide and titanium oxide compound finishing mixture 0.1-0.3;thickener 0.3-0.4; 0.15-0.30;and pH regulator. The modified crylic acid has the lowest temperature to form film being 0-5deg.C and glassifying temperature being 10-15deg.C, the coating contains 6 organic compound lower than 5g/l,is suitable for decoration and protection for inside wall.

Description

technical field [0001] The invention relates to an environment-friendly nano-material modified interior wall latex paint. Background technique [0002] Traditional interior wall latex paints need to add a large amount of organic solvents such as antifreeze and film-forming aids when preparing the paint, resulting in a high content of volatile organic compounds (VOC) in the paint; in addition, in order to prevent corrosion of the paint during storage Deterioration and mildew of the coating film, a large amount of organic anti-mold fungicides harmful to the human body need to be added to the coating, which not only directly affects the physical and mental health of the occupants, but also has timeliness. After a period of time, it loses the anti-mold Mildew effect. In interior decoration, since wooden furniture, plywood and other woods and solvent-based wood paints will release a large amount of organic volatiles such as formaldehyde and / or benzene that are highly toxic to th...
