Coating, preparation method and application thereof

Abstract

The invention provides a coating, a preparation method and an application thereof. The coating comprises the following components in parts by weight: 400-500 parts of odorless emulsion, 600-700 partsof colorful sand, 10-30 parts of coalescing agent, 0.5-4 parts of organic silicon pH regulator, 8-15 parts of cellulose, 0.5-2 parts of plant de-foaming agent and 450-500 parts of RO purified water. The prepared coating has excellent water resistance, appearance and processability; the coating has little odor and is low in content of VOC, SVOC, free formaldehyde and heavy metal; the preparation method is simple; the raw materials are easily acquired and are low in cost; the coating can be used for decorating household or commercial inner walls.

Description

technical field [0001] The invention belongs to the field of coatings, in particular to a coating and its preparation method and application. Background technique [0002] With the improvement of people's quality of life, odor-cleaning products have become very popular coating products nowadays. At present, there are two main "clean taste" technologies on the market: the first is to strictly require the emulsion supplier to extract the emulsion product as many times as possible, so as to reduce the content of monomers in the emulsion to achieve the purpose of clean taste. This method is True deodorizing technology. The odor-cleaning paint product developed based on this idea has low monomer content and low volatility, and is a real odor-cleaning paint. The other is to use flavor additives to cover the smell of the lotion. In essence, it uses other smells to cover up the smell of the lotion itself. It is actually a "pseudo-cleaning" technology. In essence, the environmenta...

[0005] CN105111856A discloses an environment-friendly imitation stone paint for interior walls. The environment-friendly interior wall imitation stone paint is prepared from the following components and weight / number ratios: 6.0-12.0 parts of water, 0.14-0.16 parts of hydroxyethyl cellulose, 0.04-0.06 parts of water-based multifunctional additives, 11.0-16.0 parts of deodorizing emulsion, 0.5-0.8 parts of film-forming aids, 0.35-0.5 parts of co-solvents, 0.25-0.5 parts of nano-zinc oxide paste, and 0.08-0.12 parts of defoamers , 0.04-0.06 parts of rheological additives, 73.0-78.0 parts of aggregate; the VOC and formaldehyde content of the imitation stone paint for interior walls prepared by the invention is relatively low, but it still needs to be improved in terms of reducing VOC and formaldehyde content, and it is not disclosed The smell of imitation stone paint on the interior wall

[0006] CN107814513A discloses a kind of colored sand paint for interior walls and its preparation method, the purpose is to solve the technical problems that the existing real stone paint has high formaldehyde content, is not suitable for interior walls and cannot be used to prepare high-brilliance colors

The technical scheme adopted in the present invention is: a kind of colored sand paint for interior walls, which is composed of the following raw materials in parts by weight: 120-170 parts of odor-cleaning emulsion, 1.2-2.5 parts of cellulose, 1 part of multifunctional auxiliary agent, and film-forming auxiliary agent 6-10 parts, 5 parts of propylene glycol, 60-100 parts of water, 700-750 parts of glass colored sand, 1-3 parts of associative alkali-swellable thickener, 1-3 parts of Cathone preservative, mineral oil defoaming 1-3 parts of agent; the interior wall colored sand paint prepared by the invention has extremely low odor and VOC, but its water resistance is poor

[0007] CN106366814A discloses a kind of sand-containing colorful environmental protection coating and its preparation method. It consists of pigment components, dispersion medium and varnish. The pigment components include RO water, cellulose, dispersant, pigments and fillers, defoamers, film-forming aids , emulsion, antifreeze, inorganic protective colloid solution, PH regulator, bactericide, first thickener and natural colored sand; dispersion medium includes RO water, film-forming aid, rheological agent, emulsion, organic protective colloid solution, Defoamer and coupling agent; Varnish comprises RO water, emulsion, pH regulator, bactericide, defoamer, film-forming aid, antifreeze and the second thickening agent; The environmental protection coating prepared by this invention has better Adhesion, water resistance and roughness, but no mention of reducing VOC content and odor
