Embodiment 1～6

[0043] The coating curing method of embodiment 1~6 finish paint and primer:

[0044] a) Spray the UV-curable primers in Examples 1 to 6 on the PC substrate after the pretreatment step, the coating film thickness is 8 μm, leveling for 5 minutes under the irradiation of infrared lamp at 50 °C, 700 mJ / cm 2 energy curing;

[0045] b) then vacuum coating;

[0046] c) Spray the UV-curable topcoat in Examples 1 to 6 on the vacuum coating, the coating film thickness is 15 μm, leveling under the irradiation of infrared lamp at 60°C for 7 minutes, 1100mJ / cm 2 Energy hardened.

[0047] The pretreatment steps of the UV-curable primer in Examples 1 to 6 are:

[0048] a) Preheating the acrylic group-containing resin in the UV-curable primer of Examples 1-6 at 40-50°C for 1-2 hours, and dissolving it with 2 / 3 volume of diluent to obtain the first solution;

[0049] b) Add the acrylic monomer, photoinitiator and adhesion promoting resin in the UV-curable primer of Examples 1-6 to the firs...

Abstract

The invention provides an UV-light (ultraviolet light) solidified stereoscopic diamond plating lacquer which comprises a primer and a finish paint, wherein the primer comprises the following components in parts by weight: 20 to 30 parts of difunctional aliphatic polyurethane acrylic resin, 1 to 10 parts of silicon dioxide grafting modified compound, 10 to 15 parts of trifunctional acrylate monomer, 1 to 2 parts of adhesion promoting resin, 2 to 5 parts of photoinitiator, 25 to 60 parts of diluent and 0.01 to 0.5 parts of aiding agent; and the finish paint comprises the following components in parts by weight: 20 to 40 parts of high-functional aliphatic polyurethane acrylic resin, 5 to 15 parts of difunctional aliphatic polyurethane acrylic resin, 5 to 15 parts of hexa-functional acrylate monomer, 1 to 5 parts of the adhesion promoting resin, 1 to 5 parts of photoinitiator, 20 to 60 parts of diluent and 0.2 to 2 parts of the aiding agent. The UV-light solidified stereoscopic diamond plating lacquer is used for solving the problems in the prior art that the UV-light solidified lacquer is single in appearance, poor in stability, poor in friction resistance and poor in basal body adhesion.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an ultraviolet light curing three-dimensional diamond coating. Background technique [0002] In order to make the vacuum-coated coating smooth and have metallic luster and brightness, it is necessary to paint the surface to be coated before and after coating. The commonly used paint is UV-curable paint. The products made by vacuum coating process combined with UV curing paint can only reflect the metal bright effect of a single flat mirror surface. As consumers have increasingly higher requirements for the appearance of UV-curable paints used in vacuum coatings, they demand more products with three-dimensional diamond shining appearance effects, high stability, high wear resistance, and strong adhesion. Contents of the invention [0003] The purpose of the present invention is to provide a UV-curable three-dimensional diamond coating to solve the technical problems in the prior art tha...
