Problems solved by technology

At present, the preparation of drop-shaped effect paint is basically based on polyurethane acrylate resin. Compared with UV coatings, this type of coatings has traditional disadvantages such as large energy consumption and slow curing speed. Although UV coatings have superior performance, there will be some problems during use. It cannot be recoated, the adhesion of recoating is not good, it is easy to fall off, etc., and the size of water droplets cannot be adjusted, which limits its application in water drop-shaped artistic effect paints

Abstract

The invention relates to a UV-cured drop-shaped effect coating and a using method thereof. The UV-cured drop-shaped effect coating is divided into finishing coat A and primer B. The finishing coat A is prepared from, by weight, 55-65 parts of UV-cured resin, 5-10 parts of UV photoinitiator monomers, 1.0-3.5 parts of a photoinitiator, 0.5-1.5 parts of auxiliaries and 20-30 parts of a solvent, the primer B comprises the following components in parts by weight: 85-100 parts of finish paint A and 0-15 parts of general color paste, wherein the UV curing resin is mixed resin of three kinds of resin,and the three kinds of resin are respectively Eternal 6071, Eternal 6172-1 and Eternal 621A-80. Compared with the prior art, the invention has the advantages of high drying speed, energy saving, environment friendliness, excellent performance, adjustable drop-shaped effect and the like.

Description

technical field [0001] The invention relates to the technical field of UV coatings, in particular to a UV curing drop-shaped effect coating and a use method thereof. Background technique [0002] At present, with the increasingly stringent national environmental protection policies, the solvent-free process of coating products is increasingly intensified. In order to meet environmental protection requirements, research on UV coatings has become a hot spot. UV coatings have the advantages of fast curing speed, less solvent, strong chemical resistance and high surface gloss. However, UV coatings are currently more widely used in the field of varnishes and inks with thinner coatings. This is due to the refraction, reflection and absorption of light by the pigment, which blocks the ultraviolet rays from extending to the inside of the coating to cause curing, while varnishes and colored inks are easy to shine through due to the thinner coating thickness. In the face of UV coati...
