Abstract

The invention provides ultraviolet curing vacuum plating coating which includes ultraviolet curing vacuum plating primer and ultraviolet curing vacuum plating surface coating; the ultraviolet curing vacuum plating primer part by weight comprises 5-70 portions of urethane acrylate resin, 10-80 portions of acrylate monomer, 2-10 portions of light initiator, 0.05-10 portions of leveling agent, 0.5-20 portions of other auxiliary agents; the ultraviolet curing vacuum plating surface coating part by weight comprises 0.5-50 portions of urethane acrylate resin, 5-40 portions of epoxy acrylic resin, 20-40 portions of butyl acetate, 10-30 portions of cyclohexanone, 5-20 portions of ethanol, 0.3-6 portions of adhesion promoter and 0.5-15 portions of light initiator. The ultraviolet curing vacuum plating coating in the invention has the advantages of high heat resistance, good adhesive force and good weatherability.

Description

technical field [0001] The present invention relates to the field of coatings, more specifically, to the field of ultraviolet curing coatings, in particular to an ultraviolet curing vacuum coating coating and a preparation method thereof. Background technique [0002] At present, the UV-curable vacuum coating coating technology uses polyurethane acrylate as the main resin of the primer formula. Its main function is to provide good flexibility and certain adhesion of the cured film; Provides hardness, fast curing performance and good adhesion performance, but its high brittleness limits its dosage in the formula, so its dosage should not be too high; It is impossible to completely convert, so the amount of monofunctional reactive diluent in the formula should not be too high, which will lead to excessive viscosity of the coating and inconvenient use. [0003] In China, Gong Jianzhong (Shanghai Coatings, No. 1, 2001, page 3) reported the development of vacuum-coated UV-cured ...
