Problems solved by technology

[0002] The acrylic emulsion wood coatings currently on the market also have the following disadvantages: 1. The coating film is soft and has poor sandability; 2. The coating has poor permeability to the substrate, which makes the adhesion between the coating film and the substrate after film formation Insufficient effort; 3. Acrylic emulsion mainly relies on physical film formation, the water resistance and solvent resistance of the coating film are poor, and the phenomenon of "hot stickiness and cold brittleness" of the coating film is serious; 4. The gloss of the coating film is low and the fullness is poor

Abstract

The invention discloses a corrosion-resistant wood coating which is prepared from the following raw materials in parts by weight: 10-12 parts of octylisothiazolinone, 2-3 parts of sodium pyrophosphate, 0.1-0.13 part of potassium periodate, 1-2 parts of sodium acetate, 7-10 parts of chitosan, 24-30 parts of polyvinyl alcohol, 0.1-0.2 part of nano alpha-Fe2O3, 1.3-2 parts of polyglycerol fatty acid ester, 2-3 parts of sericin, 5-7 parts of beewax, 70-100 parts of natural latex, 560-600 parts of an acrylic emulsion, 140-160 parts of titanium oxide, 0.7-1 part of N,N-diethyl aniline, 1-2 parts of polyvinylpyrrolidone, 3-5 parts of 2-mercapto benzimidazole, 0.3-1 part of epoxy cotton seed butyl oleate and 0.7-1 part of sea buckthron oil. The octylisothiazolinone, the polyvinylpyrrolidone and the like which are added can effectively improve the corrosion resistance of the film and enhance the weather resistance of the film.

Description

technical field [0001] The invention relates to the technical field of wood coatings, in particular to a preservative wood coating and a preparation method thereof. Background technique [0002] The acrylic emulsion wood coatings currently on the market also have the following disadvantages: 1. The coating film is soft and has poor sandability; 2. The coating has poor permeability to the substrate, which makes the adhesion between the coating film and the substrate after film formation Insufficient effort; 3. Acrylic emulsion mainly relies on physical film formation, the water resistance and solvent resistance of the coating film are poor, and the phenomenon of "hot stickiness and cold brittleness" of the coating film is serious; 4. The gloss of the coating film is low and the fullness is poor . Therefore, in order to improve the above shortcomings, it is particularly important to modify the acrylic emulsion coating.
