High solid content UV vacuum plating coating, and preparation method thereof

Abstract

The invention discloses a high solid content UV vacuum plating coating. The high solid content UV vacuum plating coating comprises, by weight, 23 to 28% of urethane acrylate, 6 to 10% of modified epoxy acrylate, 13 to 18% of a special polyester acrylate, 12 to 17% of hydroxypropyl methacrylate, 2 to 4% of dipentaerythritol hexaacrylate, 6 to 12% of ethoxylated trimethylolpropane triacrylate, 1 to 2% of amine acrylate, 1 to 5% of 1-hydroxyl-cyclohexyl-benzyl ketone, 4 to 8% of butyl acetate, 4 to 8% of acetic ether, and 10 to 15% of a special solvent. According to a preparation method, excellent wetability and levelling properties are achieved via artful combination and the special preparation method of special monomers and resin, mirror surface effect of metal surface large area spraying can be achieved, sagging is not easily caused, plumpness is excellent, operation is convenient in operation process, and the high solid content UV vacuum plating coating is a metallic paint with excellent performance suitable for automobiles, bicycles, motorcycles, and electrombiles.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special light exterior paint for metal devices such as automobiles, motorcycles, electric vehicles and bicycles, that is, a high-solid UV vacuum coating coating and a preparation method thereof. Background technique [0002] With the increasingly stringent global environmental protection requirements and the restrictions on VOC in the international decorative coatings market, the use of low-solvent and low-pollution coatings has become a development trend, especially low-solvent high-solid coatings are developing rapidly and are widely used. At present, the methods for reducing the content of organic solvents in coatings mainly adopt powder coatings, UV curing coatings, high solid content coatings and water-based coatings. Among them, UV curing coatings mainly refer to a new class of coatings that are rapidly cross-linked and cured to form a film under ultraviolet light irradia...

AI Technical Summary

Problems solved by technology

If UV coatings are introduced to metal parts such as automobiles, bicycles, motorcycles and electric vehicles, the production process will be greatly simplified, production efficiency will be improved, energy consumption and environmental pollution will be reduced, but ordinary UV coatings are difficult to adhere to metal surfaces

Moreover, the existing UV vacuum coating paint mainly has a solid content of about 50% and contains a large amount of organic solvents, which has a certain impact on the environment and the human body during the coating process, but the paint with high solid content contains less organic solvents. , the wettability of the color and the substrate is not as good as the film paint with low solid content. In contrast, the construction is more difficult, especially for the surface treatment of metal materials.
