Embodiment 1

[0035] A kind of crystal texture coating provided by the present embodiment, by mass percentage, comprises the following components:

[0036]

[0037]

[0038] Wherein, the short-oil alkyd resin is formed by condensation polymerization of glycerin, phthalic anhydride and soybean oil, wherein the mass percentage of soybean oil is 35%, and the mass percentage of phthalic anhydride is 30%. Blocked polyisocyanate is a polymer produced by the reaction of polyisocyanate and ethylene glycol monobutyl ether, in which polyisocyanate is composed of toluene diisocyanate, diphenylmethane diisocyanate and 1,6-hexamethylene diisocyanate in a molar ratio of 1:1 : 1 addition comes. The median particle size of the wax slurry was 5 μm. The cooked tung oil is cooked pure tung oil, and its extraction method is to fry the tung seeds and squeeze the oil without artificially adding any chemical components.

Embodiment 2

[0040] A kind of crystal texture coating provided by the present embodiment, by mass percentage, comprises the following components:

[0041]

[0042]

[0043] Among them, the short oil alkyd resin is formed by condensation polymerization of ethylene glycol, phthalic anhydride and oleic acid, wherein the mass percentage of oleic acid is 38%, and the mass percentage of phthalic anhydride is 28%. Blocked polyisocyanate is a polymer produced by the reaction of polyisocyanate and caprolactam, in which polyisocyanate is obtained by adding toluene diisocyanate and 1,6-hexamethylene diisocyanate in a molar ratio of 1:1. The wax powder has a median particle size of 15 μm. The cooked tung oil is cooked pure tung oil, and its extraction method is to fry the tung seeds and squeeze the oil without artificially adding any chemical components.

Embodiment 3

[0045] A kind of crystal texture coating provided by the present embodiment, by mass percentage, comprises the following components:

[0046]

[0047] Wherein, the short oil alkyd resin is formed by condensation polymerization of pentaerythritol, phthalic anhydride and castor oil, wherein the mass percentage of castor oil is 36%, and the mass percentage of phthalic anhydride is 35%. Blocked polyisocyanate is a polymer produced by the reaction of polyisocyanate and imidazole, in which polyisocyanate is obtained by adding diphenylmethane diisocyanate and 1,6-hexamethylene diisocyanate in a molar ratio of 1:1. The wax powder has a median particle size of 500 nm. The cooked tung oil is cooked pure tung oil, and its extraction method is to fry the tung seeds and squeeze the oil without artificially adding any chemical components.

Abstract

The invention belongs to the technical field of coatings and in particular relates to an environment-friendly high-performance crystallized coating. The crystallized coating comprises the following components in percentage by mass: 40-70 percent of a short oil alkyd resin, 5-20 percent of closed polyisocyanate, 5-20 percent of boiled tung oil, 5-20 percent of a solvent, 0-10 percent of a phenylated amino resin, 0-2 percent of a leveling agent, 0-5 percent of a slip additive, 0-3 percent of a closed acid catalyst and 0-2 percent of an adhesion promoter. Compared with the prior art, the crystallized coating disclosed by the invention has the advantages that the formula stability is high, and the storage period is long; the coating does not yellow when baked at a high temperature; the coating is environment-friendly and does not contain cobalt, manganese or other limited driers, the odor is small in the construction process, environment friendliness is realized, and the environment-friendly requirement is met; and moreover, coating in a roller painting mode can be realized, the loss is low, and the production efficiency can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to an environment-friendly, high-performance crystal coating. Background technique [0002] Art paint, also known as art paint, is a paint variety with special performance composed of special materials and belongs to industrial paint. Like other paints, applying this kind of paint on the surface of the object will protect the object. The difference is that after the paint is formed into a film, various beautiful patterns or patterns will be formed or appear on the film. The appearance is colorful and layered. Clear, beautiful and generous, with obvious high decoration. [0003] Crystal texture paint is a kind of art paint, which is named for the crystal-like appearance of the paint film. The texture of the coating film is clear and sparkling, with unique visual effects, which can cover up the defects of the substrate. It has super decorative properties, smooth touch and strong la...
