Abstract
The invention belongs to the technical field of matte coatings, and particularly relates to a preparation method of a water-based UV-cured wear-resistant anti-fouling matte coating and a coating film, wherein the matte coating is composed of A, B, C three major components, wherein the component A comprises the following raw materials in parts by weight: 30-35 parts of waterborne UV aliphatic polyurethane acrylic dispersion and 13-18 parts of waterborne UV fluorine-silicon modified stain-resistant resin; the invention adopts special wear-resistant powder to provide extinction effect and greatly improve the wear resistance of the paint film; the waterborne UV fluorine-silicon modified stain-resistant resin and the waterborne UV aliphatic polyurethane acrylic dispersion are compounded, so that a paint film has stain resistance, hydrophobic self-cleaning performance and wear resistance and high-quality appearance; the solid content is high, the workability is excellent, and orange peel and sagging are avoided; the cured coating has good appearance, no low bite, no flowering and fine and smooth texture; and the storage stability of the coating is excellent, and the shelf life of the water-based matte UV coating and the stability of the coating in the shelf life are improved.
Description
Technical Field
The invention relates to the technical field of matte coatings, in particular to a water-based UV-cured wear-resistant anti-fouling matte coating and a preparation method of a coating film.
Background
The UV-cured water-based paint has the advantages of environmental protection, high efficiency, energy conservation and the like, has excellent surface properties such as strong adhesive force after film formation, higher hardness, good chemical resistance and weather resistance and the like, is widely applied to the fields of electronic products, furniture, automotive trim and the like, is mainly applied to exterior finish paint on base materials such as plastics, metals, glass and the like, and ensures that the product has good exterior finish and excellent properties. In electronic products such as computers, mobile phones, flat panels and related matching parts in the 3C field, the proportion of water-based matte UV coatings used in the appearance paint market is more, the gloss is generally between 4 and 6 degrees, and the products can be protected with certain functionality and the visual aesthetic feeling can be improved.
Most of the existing series of UV dirt-resistant self-cleaning coating systems belong to solvent-based UV coatings, and have high VOC content and poor environmental protection; the aqueous UV system mainly takes aqueous fluorine-silicon modified resin as a main body or fluorine-containing silicon stain-resistant hydrophobic auxiliary agent to improve the stain resistance of the aqueous UV system, is popular in the market, but still has the following defects when applied to aqueous matte finishing paint:
(1) the cured coating has the defects of heavy base biting, fine floating, yellowing resistance and the like on a base material or a primer;
(2) along with the change of the gloss of a paint film to be dumb, the scratch resistance, stain resistance, hydrophobic self-cleaning effect are obviously weakened;
(3) in addition to the stain-resistant, hydrophobic and self-cleaning properties, the general aqueous fluorosilicone modified resin has certain wear resistance due to higher functionality, but is still insufficient for high wear resistance.
Disclosure of Invention
The invention aims to develop a UV finishing paint in the 3C industry, the gloss of a paint film of the UV finishing paint is stable between 4 and 6 degrees, the UV finishing paint still has excellent wear resistance and stain resistance, and the UV finishing paint has fine and smooth appearance.
In order to achieve the purpose, the invention adopts the following technical scheme:
a water-based UV-curing wear-resistant anti-fouling matte coating is composed of A, B, C following three major components:
the component A comprises the following raw materials in parts by weight: 30-35 parts of water-based UV aliphatic polyurethane acrylic dispersoid, 13-18 parts of water-based UV fluorine-silicon modified stain-resistant resin, 2-3 parts of photoinitiator, 0.2-0.5 part of PH regulator, 0.5-1.0 part of wetting agent, 0.5-1 part of flatting agent, 0.2-0.4 part of defoaming agent, 0.5-1 part of wax slurry, 20-30 parts of wear-resistant powder, 3-4.5 parts of wetting dispersant, 2-3 parts of anti-settling agent, 0.5-2 parts of thickening agent, 2-4 parts of cosolvent and 10-15 parts of deionized water;
