Embodiment 1

[0040] A water-based paint for woodware suitable for high-pressure airless spraying. The water-based paint for woodware is made of the following raw material ratios, calculated by weight percentage:

[0041] 78% water-based self-crosslinking acrylic emulsion, 13.2% deionized water, 0.2% pH regulator, 0.5% wetting agent, 1.5% matting powder, 0.5% defoamer, 4% film-forming aid agent, 0.9% thickener, 0.2% light stabilizer, 0.2% light absorber, 0.8% leveling agent.

[0042] The water-based self-crosslinking acrylic emulsion is an acrylic emulsion with a core-shell structure, does not contain APEO, has a high solid content, and a water-based self-crosslinking acrylic emulsion with a minimum film forming temperature MFT lower than 5°C; the wetting agent is polyether-modified polysilicon Oxane wetting agent; defoamer is polyether modified siloxane copolymer defoamer containing fumed silica; film-forming aid is dipropylene glycol methyl ether (DPM); matting powder is the precipitation...

Abstract

The invention discloses carpentry water paint suitable for high pressure airless spraying and a preparation method thereof and relates to the technical field of paint composition. The carpentry water paint is prepared in proportion by the following raw materials including, calculated by weight percentage, 70-80% of water-based self-crosslinking acrylic emulsion, 10-20% of deionized water, 0.1-0.3% of pH conditioning agent, 0.1-0.5% of wetting agent, 0.2-0.6% of defoaming agent, 1-5% of coalescing agent, 0-2% of extinction powder, 0.5-1% of thickening agent, 0.1-0.3% of light stabilizer, 0.1-0.3% of light absorber and 0.3-0.8% of flatting agent; the carpentry water paint suitable for the high pressure airless spraying is prepared by uniformly mixing and stirring the above raw materials. The carpentry water paint has the advantages of being healthy, environmentally friendly, capable of being coated in a thick mode, strong in adhesive force and fast in dryness; the superstrong weather resistance and the superstrong water resistance are achieved; the construction is convenient and fast, the thickness can be achieved rapidly, the paint film is level and smooth, the hand feeling is also good, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of coating compositions. Background technique [0002] At present, home decoration has become a fashion. In terms of paint for home wood decoration, most families still use solvent-based wood paint. These products are not environmentally friendly and unhealthy. They use a large amount of toxic, harmful, easily polluting, and flammable organic solvents. During or after construction, a large amount of toxic and harmful gases such as benzene and free TDI are volatilized, causing serious indoor pollution. According to a report released by the China Consumers Association, one-third of the leukemia children's onset is directly related to home decoration, and ordinary solvent-based wood paint has become a "killer" that pollutes the environment and damages consumers' health. Moreover, solvent-based wood paint has poor outdoor weather resistance and poor water resistance; it cannot be thickly coated, and the constru...
