[0003] At present, the environmentally friendly latex paints on the market mainly have the following disadvantages: 1) Although the content of harmful gases released can meet the GB18582-2008 standard, it is far from reaching the low VOC standard; 2) The anti-formaldehyde function it has is only physical The adsorption process cannot fully achieve the effect of decomposing formaldehyde; 3) It cannot absorb dust and small particles in the air, and has limited purification effect on indoor air; 4) The cost is too high, and the sales price is not close to the people, so it cannot be popularized and applied

[0034] The preparation method of above-mentioned haze removal interior wall latex paint comprises the following steps:
[0035] 1) Premixing: Add water and dispersant to the disperser, mix evenly, then add modified hydroxyethyl cellulose, mix evenly, then add wetting agent, filler, rutile titanium dioxide and nano tourmaline powder, then add pH Regulator, mix well;
[0036] 2) Thinning: Sampling and testing, when the particle size is less than 50 μm, add film-forming aids, bactericides, preservatives and thickeners, mix well, then add hydrophobic and oil-repellent emulsion, functional additives and defoamers, mix Uniformly, get the interior wall latex paint that removes haze.
[0037] Preferably, the preparation method of the above-mentioned haze removal interior wall latex paint may further comprise the steps:
[0038] 1) Premixing stage: add water and dispersant to the disperser, adjust the speed to 400-600r / min, stir for 1-3min, then add modified hydroxyethyl cellulose, s...

Abstract
The invention discloses haze-removal interior wall latex paint and a preparation method thereof. The latex paint is prepared from the following raw materials in parts by mass: 25-30 parts of a hydrophobic and oleophobic emulsion, 15-20 parts of rutile type titanium dioxide, 5-10 parts of nano tourmaline powder, 0.3-0.5 part of modified hydroxyethyl cellulose, 3-18 parts of filler, 0.5-1.0 part of a defoamer, 0.1-2.0 parts of a dispersant, 0.5-1.0 part of a thickener, 0.1-0.5 part of a sterilizing agent, 0.1-0.5 part of a preservative, 0.1-0.5 part of a pH regulator, 0-2 parts of a coalescing agent, 0-5 parts of a function additive and 15-25 parts of water. The haze-removal interior wall latex paint disclosed by the invention is low in VOC, can decompose formaldehyde and release negative oxygen ions, and can remarkably improve the indoor air environment if being used for indoor decoration, and people can live in the house quickly. Compared with same types of products in the market, the latex paint has the characteristics of being high in contrast ratio, excellent in washing resistance, stain resistance and the like. The latex paint is simple in preparation method and low in cost and can be widely popularized and used.
Description
technical field [0001] The invention relates to a haze-removing interior wall latex paint and a preparation method thereof, belonging to the technical field of paints. Background technique [0002] In recent years, with the rapid development of industry, air pollution has become more and more serious, which has attracted people's attention. Air pollution mainly comes from three aspects: 1) industrial pollution: smoke, sulfide, nitride, halide and other harmful substances discharged from factories; The soot, sulfur dioxide, etc. discharged into the atmosphere by fossil fuels have the characteristics of large emission, wide distribution, and low emission height, which are harmful; 3) Automobile exhaust pollution: the exhaust gas emitted is mainly carbon monoxide, sulfur dioxide, nitrogen oxides and carbon dioxide. Hydrogen compounds, etc. These pollutants are very harmful to the respiratory organs of the human body. PM2.5 is an important indicator to measure particulate matt...
