Problems solved by technology

This kind of paint is also a two-coat type, which is suitable for the coating of plastic casings such as mobile phones, digital cameras, and cosmetic boxes. It has a good metallic effect and a high-gloss, high-volume appearance, but its components are more The paint contains 40-50 parts by mass of methyl ethyl ketone, and the topcoat also contains 35-46 parts by mass of methyl ethyl ketone. This kind of paint will not only cause air pollution when it is cured, but also has the danger of burning

Abstract

The invention discloses an ultraviolet curing coating for a housing of a battery car as well as a preparation method and a spray-coating method. The ultraviolet cutting coating is characterized by consisting of a primer and a finish paint, wherein the primer comprises the following components in percentage by weight: 20 to 40 percent of epoxy acrylate, 10 to 20 percent of urethane acrylate, 2 to 6 percent of 1,6-hexanediol diacrylate, 30 to 40 percent of trimethylolpropane triacrylate, 1 to 5 percent of 1-hydroxycyclohexyl phenyl ketone, 3 to 8 percent of benzyl dimethyl ketone and 0.2 to 1 percent of polyether modified polydimethylsiloxane; the finish coat comprises the following components in percentage by weight: 40 to 60 percent of acrylic ester modified solvent-containing oligomer, 30 to 50 percent of trimethylolpropane triacrylate, 5 to 10 percent of 1-hydroxycyclohexyl phenyl ketone, 1 to 3 percent of 2,4,6-trimethylbenzoyldiphenyl phosphine oxide, 0.5 to 2 percent of polyether modified polydimethylsiloxane, 1 to 3 percent of trifunctional acid ester and 1 to 3 percent of nanoscale color concentrate. The coating is efficient, energy-saving, economic, environment-friendly, scratch-resistant, wear-resistant, bright in color and less in curing investment, and can be easily produced on an assembly line, and a preparation process is simple.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet light curing coatings, and in particular relates to an ultraviolet light curing coating used for battery car shells and its preparation and application methods. Background technique [0002] The shell of the battery car must undergo a lot of surface treatment on the basis of ABS / PC plastic mold forming to achieve a beautiful and wear-resistant effect. At present, most of the treatment methods use heat-curing paint as a primer, which has long baking time, high energy consumption and solvents. Volatilization in a limited space is easy to catch fire and pollute the environment, while the top coat is protected by a single UV varnish, which lacks intermediate protection and has a weak metallic texture. At the same time, different equipment is required for the primer, which brings inconvenience to production. Strong limitations. [0003] UV-curable coating is a kind of green and environment-friendl...
