Embodiment 1

[0058] By weight percentage, first 15% of ethyl acetate, 10% of butyl acetate, and 8% of isobutanol are mixed to prepare a mixed solvent for subsequent use; , is aliphatic urethane acrylate), thermoplastic acrylic resin 15% is added in the container, then adds photocuring initiator 3% [photocuring initiator selects Swiss Ciba 819, is bis(2,4,6-trimethylbenzene Formyl) phenyl phosphine oxide] and 0.3% of defoamer (defoamer chooses Tego 920), leveling agent 0.5% (leveling agent chooses Tego 2100), dispersant 0.2% (dispersant chooses Tego 681 ), after the formed mixture is uniformly dispersed at a low speed, add the above-mentioned mixed solvent, then fully stir for 10 to 15 minutes, and finally add 3% of nano-pigments (nano-pigments are selected from the various color pigments of Chaoquan Chemical), after the dispersion is uniform Filter with 400 mesh gauze to get the finished product.

Embodiment 2

[0060]According to the percentage by weight, first mix 20% ethyl acetate, 10% butyl acetate and 10% isobutanol to prepare a mixed solvent for later use; then take 10% hydroxyl acrylic resin and 25% polyurethane acrylate EB264, is aromatic polyurethane acrylate), 15% of thermoplastic acrylic resin is added to the container, and then 3% of photocuring initiator is added [photocuring initiator is selected from Beijing Yingli 907, which is 2-methyl-1-(4-methyl Mercaptophenyl)-2-morpholine-1-acetone] and defoamer 1% (defoamer selects Bayer 020), leveling agent 0.5% (leveling agent selects Bayer 306), dispersant 0.5% (dispersant Choose Bayer 168), after the formed mixture is uniformly dispersed at a low speed, add the mixed solvent prepared above, then fully stir for 10 to 15 minutes, and finally add 5% nano-pigments (nano-pigments are selected from Yiming Sebao’s various color pigments) After dispersing evenly, filter with 400 mesh gauze to get the finished product.

Embodiment 3

[0062] According to percentage by weight, first mix 15% ethyl acetate, 10% butyl acetate, and 8% isobutanol to prepare a mixed solvent for later use; Leaf UV2100, is aromatic polyether urethane acrylate), thermoplastic acrylic resin 15% is added in the container, then adds photocuring initiator 3% (photocuring initiator selects Beijing Yingli 1173, is 2-hydroxyl-2-methyl -1-phenylacetone) and 1% of defoamer (Deqian 2700 is used for defoaming agent), 1% of leveling agent (Deqian 435 is used for leveling agent), 1% of dispersant (Deqian 912 is used for dispersant) , after the formed mixture is uniformly dispersed at a low speed, add the mixed solvent prepared above, then fully stir for 10 to 15 minutes, and finally add 4% nano-pigments (nano-pigments are selected from Changxing Chemical's various color pigments), and disperse evenly with 400 The finished product is obtained by filtering with mesh gauze.

Abstract

The invention belongs to the technical field of paints, and particularly relates to a vacuum-plating ultraviolet curing intermediate paint, which includes the following raw materials by weight: 10%-20% of hydroxy acrylic resin, 25%-35% of polyurethane acrylates, 15%-20% of thermoplastic acrylic acid resin, 15%-25% of ethyl acetate, 10%-15% of butyl acetate, 8%-15% of isobutanol, 3%-10% of nano-pigments, 3%-5% of ultraviolet-curing initiators, and 1%-3% of additives. The invention has a fast-curing property, good wearability, pollution resistance, hard-object scratch resistance, high glossiness, low volatility, is environment-friendly and free of pollution, can be widely used to spray electronic or electric appliance products and cosmetic containers.

Description

Technical field: [0001] The invention belongs to the technical field of coatings, in particular to a vacuum electroplating ultraviolet light curing primer. Background technique: [0002] At present, various electronic or electrical products, cosmetic containers, such as digital cameras, notebook computers, mobile phones, cameras, MP4, etc. have been widely used in people's lives. The shell of this kind of product is mostly made of plastic or plastic material, and it is easy to damage the appearance of the product by frequent friction during use, and when the hand touches the shell of the product, hand sweat will have a certain degree of corrosion on the shell of the product, affecting the quality of the product. service life. Therefore, after the shell is processed and formed, it is necessary to spray protective and decorative coatings on the surface. The purpose is to improve its weather resistance, chemical resistance and surface hardness, reduce insulation performance, p...
