preparation example Construction

[0047] A preparation method for indoor multifunctional water-based paint, comprising the following steps:

[0048] 1) Mix 60%-90% of distilled water, dispersant, 40%-60% of thickener, co-solvent, wetting agent, 50%-70% of defoamer, 12%-50% of mildew and sterilization Agent mixing and stirring to disperse;

[0049] 2) Add titanium dioxide, talc powder, mica powder, and negative ion additives in sequence to the high-speed dispersion mixing tank, and after stirring and dispersing evenly, use a horizontal sand mill to sand the material until the fineness of the material is below 30 microns;

[0050] 3) Add hydroxyethyl cellulose, film-forming aid, and remaining defoamer to the dispersion tank, stir and disperse evenly;

[0051] 4) Add acrylate deodorizing emulsion, remaining anti-mold and fungicide, waterproofing agent, rheology modifier, plant extract, remaining distilled water to the dispersion tank in sequence, stir and disperse evenly, and adjust the viscosity with the remain...

Embodiment 1

[0056] Add 150kg of distilled water, 0.3kg of thickener, 10kg of co-solvent ethylene glycol, 6kg of dispersant SN-5040, 2kg of defoamer 643, 1kg of wetting agent, and 1kg of anti-mold and fungicide 623 into the mixing tank. —700 rpm, disperse for 15 minutes, then add 200kg titanium dioxide, 50kg talc powder, 50kg mica powder, 8kg negative ion additives in sequence, and disperse at high speed for 30 minutes at a stirring speed of 1000-1200 rpm. Sand the mill until the fineness of the material is below 30 microns; then add 0.3kg of thickener, 12kg of film-forming aid OE-300, and 1.5kg of defoamer NXZ in turn, and stir at 300-600 rpm for 10 Minutes; then add 360kg of deodorant emulsion 338 (BASF styrene-acrylic deodorant emulsion), 3.5kg anti-mildew bactericide 320 (Rohm and Haas ROCIMA320), distilled water 20kg, 15kg water repellent (organic silicon Emulsion), 4kg rheology modifier (polyurethane leveling agent), 3kg lavender, aloe, green tea extract concentrate, disperse for 20 ...

Embodiment 2

[0058] 200kg of distilled water, 0.2kg of thickener (methyl hydroxypropyl cellulose), 10kg of cosolvent propylene glycol, 6kg of dispersant (Nopco SN5040), 1kg of wetting agent ND-1096, 2kg of defoamer 643, 1.5kg Add the antifungal and fungicide into the mixing tank, disperse for 12 minutes at a speed of 400-700 rpm, and then add 150kg of titanium dioxide (Billions Titanium Dioxide BLR601), 100kg of mica powder, 60kg of talcum powder, and 8kg of negative ion additives in sequence. Under the condition of stirring speed of 1000-1200 rpm, disperse at high speed for 35 minutes, and use a sand mill to grind until the fineness of the material is below 30 microns; then add 0.2kg of hydroxyethyl cellulose HBR-250, 100kg of distilled water, 10kg of film-forming aid OE-300, 1.5kg of defoamer A-10, stirred at 300-600 rpm for 10 minutes; then add 250kg of deodorizing emulsion 702 and 2kg of pre-treated steam distillation Anti-mold and fungicide (Rohm and Haas anti-mold agent ROCIMA320), 1...

Abstract

The invention relates to an indoor multifunctional waterborne coating and a preparation method thereof. The indoor multifunctional waterborne coating comprises the following raw materials in parts by weight: 20-38 parts of an acrylate purifying emulation, 18-35 parts of distilled water, 0.05-0.2 part of a wetting agent, 0.2-1 part of a dispersing agent, 0.5-2 parts of a cosolvent, 15-25 parts of titanium dioxide, 3-8 parts of talcum powder, 5-15 parts of mica powder, 0.1-0.5 part of a mildewcide biocide, 0.05-0.3 part of a plant extract, 0.3-0.8 part of an anionic additive, 1-1.5 parts of a film forming additive, 1-2 parts of a waterproof agent, 0.02-0.1 part of a thickening agent, 0.02-0.1 part of hydroxyethyl cellulose, 0.1-0.5 part of a rheology modifier and 0.1-0.5 part of a defoaming agent. The indoor multifunctional waterborne coating has the advantages of simple process, relatively low cost, high waterproofness, stability, environment friendliness and safety; the added plant extract is fresh in smell and capable of taking a favorable mosquito expelling effect; the anionic additive can be used for favorably removing harmful substances such as formaldehyde and benzene and takes the effect of purifying the environment; and the multifunctional approaches of the indoor multifunctional waterborne coating in indoor decoration are ensured.

Description

technical field [0001] The invention belongs to the field of architectural coatings, in particular to an indoor multifunctional water-based coating and a preparation method thereof. Background technique [0002] Indoor paint is a kind of decorative paint used for interior walls, doors and windows of buildings. With the improvement of living environment and the advancement of technology, people have put forward higher and higher environmental protection requirements for indoor paint, especially VOC (volatile The safety and environmental protection problems caused by non-toxic organic compounds have attracted more and more attention and attention. Some low-quality water-based interior wall coatings currently on the market have a lot of VOC exceeding the standard, and prolonged exposure will damage human health, while most door and window coatings are solvent-based coatings. harm. Therefore, multifunctional water-based paints with clean odor, low VOC or even zero VOC, anti-fo...
