Embodiment 1

[0052] Put 5 parts of silica sol into the stirring tank, add 1 part of coupling agent, 0.2 part of dispersant, 0.2 part of defoamer, and 5 parts of propylene glycol under stirring at 600rpm for 20min, and then stand for 24h for later use;

[0053] Add 8 parts of water into the dispersing kettle, add 0.2 parts of dispersant and 0.2 parts of defoamer under stirring at 500 rpm, and then add 7 parts of nano photocatalytic powder, 10 parts of pigments and fillers and 15 parts in turn after stirring evenly. Part of attapulgite, adjust the speed to 2500rpm and disperse for 30min at high speed, then grind into slurry by sand mill;

[0054] Add 45 parts of pure acrylic emulsion, pretreated silica sol and the remaining defoamer to the sand-milled slurry, adjust the speed to 1000rpm and stir for 10 minutes, then add 1 part of leveling agent, and continue stirring for 10 minutes. , Reduce the speed to 600rpm, use a pH regulator to adjust the pH to about 8.0, filter and pack.

Embodiment 2

[0056] Add 2 parts of silica sol into the stirring tank, add 0.5 parts of coupling agent, 0.2 parts of dispersant, 0.2 parts of defoamer, and 2 parts of propylene glycol under stirring at 600rpm for 15min, and then stand for 24h until use;

[0057] Add 12 parts of water into the dispersing kettle, add 3 parts of propylene glycol, 0.2 parts of dispersant, and 0.2 parts of defoamer under stirring at 500 rpm. After stirring, add 5 parts of nano photocatalytic powder and 10 parts in turn The pigments and fillers and 10 parts of diatomaceous earth, adjust the rotation speed to 2000rpm and high-speed dispersion for 30min, then grind into slurry by sand mill;

[0058] Add 35 parts of silicone acrylic emulsion, pretreated silica sol and the remaining defoamer to the sand-milled slurry, adjust the speed to 1200rpm and stir for 10 minutes, then add 0.8 parts of leveling agent, and continue stirring for 10 minutes. , Reduce the speed to 600rpm, use a pH regulator to adjust the pH to about 8.0...

Embodiment 3

[0060] Add 10 parts of water and 5 parts of propylene glycol to the dispersing kettle, add 0.4 parts of dispersant and 0.3 parts of defoamer under stirring at 500 rpm, and then add 5 parts of nano photocatalytic powder and 15 parts of defoamer in turn after stirring. Pigments and fillers and 5 parts of attapulgite, adjust the rotating speed to 2000rpm and disperse for 20min at high speed, then grind into slurry by sand mill;

[0061] Add 20 parts of polymer emulsion, pretreated silica sol and remaining defoamer to the sand-milled slurry, adjust the speed to 800rpm and stir for 10 minutes, then add 0.5 part of leveling agent, and continue stirring for 10 minutes , Reduce the speed to 600rpm, use a pH regulator to adjust the pH to about 8.0, filter and pack.

Abstract

The invention provides an automatic indoor humidity adjusting coating, which comprises the following components in parts by weight: 15-40 parts of emulsion, 0-5 parts of inorganic filming substance, 0.4-1 part of coupling agent, 2-5 parts of propylene glycol, 0.2-0.5 part of dispersing agent, 0.3-0.8 part of anti-foaming agent, 15-20 parts of pigment and filler, 5-10 parts of photo-catalytic powder, 5-20 parts of humidity adjusting material and 0.5-1 part of flatting agent. Any artificial energy is not required to be consumed; the indoor air humidity can be automatically adjusted; chemical reaction can be performed on reactant of visible light by using the photo-catalytic powder, so that surrounding oxygen and water molecules are excited into OH- and O- free negative ions with extremely high oxidation capacity; sterilization and mildew prevention effects are achieved through strong oxidation of the coating; and the coating is environmentally-friendly, nontoxic and energy-saving, and has long effective service time and obvious economical benefit and social benefit.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to an indoor humidity automatic adjustment coating. Background technique [0002] Humidity is closely related to human production and life, too low or too high humidity will affect people's normal life. When the indoor humidity is lower than 40%, human skin will be chapped, the resistance of the respiratory system will decrease, bacteria and viruses will take advantage of the weakness, furniture will deform and burst, coatings and murals will accelerate, and it will easily cause static electricity to catch fire; above 60 % When the environment is too humid, the microorganisms multiply faster, and the items are prone to mildew, rot or rust. Therefore, it is very important to control indoor humidity for production and life, especially for humid and arid areas, adjusting humidity is particularly important. [0003] Indoor humidity control usually uses air conditioners, dehumidifiers and hu...
