Embodiment 1～5

[0044] The preparation method of embodiment 1~5 ultraviolet curing matte paint is as follows:

[0045] (a) Mix the resin, acrylate monomer, photoinitiator and diluent weighed according to the proportions in Table 1, and stir at 40-50°C for 10-15 minutes at a stirring speed of 400-600 rpm.

[0046] (b) Add the silica matte powder weighed according to the ratio in Table 1, stir at 800-1200 rpm for 10-15 minutes, and filter with a 400-mesh filter cloth to obtain the product.

[0047] The coating curing method of embodiment 1~5 ultraviolet curable matte paint: the ultraviolet curable paint that embodiment 1~5 makes is sprayed on PC base material, and coating paint film thickness is 20 microns, 60 ℃ of infrared lamps Leveling under irradiation for 8 minutes, 800mJ / cm 2 Energy hardened. Spray the UV-curable paints prepared in Examples 1 to 6 onto the surface of ABS, PMMA, and PC / ABS substrates, and the coating method is the same as above.

Abstract

The invention provides an ultraviolet-curing matte paint, comprising the following raw materials in parts by weight: 15-40 parts of vinyl-containing silicone resin, 10-15 parts of high-functionality acrylate monomer, 3-10 parts of silica matte powder, 30-60 parts of diluent and 1-6 parts of photoinitiator, wherein the silica matte powder is surface-grafted modified silica powder. The ultraviolet-curing matte paint provided by the invention synergistically plays the optimal effect of the fouling-resistant, slippery and elastic paint film by coordinating the dosage of the vinyl-containing silicone resin and the surface-grafted modified spherical silica matte powder.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an ultraviolet light curing matte paint. Background technique [0002] In order to protect the plastic shell of the product from being scratched, in the prior art, the plastic shell is often protected by spraying an ultraviolet-curable coating on the surface of the object. In order to increase the matting property of the coating obtained from the paint, matte powder is often added to the paint to reduce the gloss of the coating and obtain a low gloss coating effect. [0003] As disclosed in CN200610172296.0, a UV-curable matte coating contains main resin, diluent, photoinitiator, pure acrylate and matte powder, wherein the matte powder is soaked in alcohol solvent for 0.5-2 hours Then mix and disperse with resin to improve the dispersibility and stability of matte powder. Wherein the matte powder used is ordinary silica or calcium carbonate, and the resin used is polyester acrylate, pol...
