Abstract

The invention discloses an ultraviolet light curable coating with a dewdrop effect. The coating comprises base paint and finish paint, wherein the base paint comprises the following ingredients by weight percent: 10-15% of epoxy acrylate, 18-30% of high-functionality-degree polyurethane acrylic ester A, 8-15% of a tri-functional group monomer A, 3-5% of a photoinitiator A, 0.4-0.8% of an organic silicon flatting agent and 45-55% of an organic solvent A; and the finish paint comprises the following ingredients by weight percent: 5-10% of a thermoplastic acrylic resin, 8-18% of the high-functionality-degree polyurethane acrylic ester B, 15-20% of the tri-functional group monomer B, 3-5% of the photoinitiator B, 0.1-0.3% of an acrylic acid flatting agent, 1-3% of a silane coupling agent and 50-60% of the organic solvent B. The ultraviolet light curable coating with the dewdrop effect is simple to prepare and easy to cure, and has the dewdrop effect after being cured into a coating.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a UV-curable coating with a dewdrop effect, a preparation method and a coating method thereof. Background technique [0002] Ultraviolet light (UV) curing is to use the photosensitivity of photoinitiators (photosensitizers) to form excited ecological molecules under the irradiation of ultraviolet light, decompose them into free radicals or ions, and make unsaturated organic compounds polymerize, graft and exchange. Combined chemical reactions to achieve the purpose of curing. [0003] The current UV light-curing coatings mainly play the role of decoration and protection. Among the various decorative effects, there are various colors of light, matte, vacuum coating and hammer effect. [0004] The invention with the application publication number of CN102796448A discloses a water-based two-component white varnish, which is composed of a main agent component A and a curing agent component B...
