The paint consists of alicyclic resin or alicyclic polyurethane acrylic resin 5-40 wt%, acrylic amino resin or methyl acrylic amino resin 5-40 wt%, monofunctional acrylate or monofunctional methancrylate 5-35 wt% or bifunctional acrylate or bifunctional methancrylate 5-30 wt%, trifunctional acrylate or trifunctional methancrylate 5-25 wt%, and light initiator 1-10 wt%. It is used for finishing white workpiece of automobile and motorcycle, and after UV cured, the coating is level, firm, tough, high temperature resistant, corrosion resistant and no yellowing.
Description
The invention belongs to the photo-cured coating in the chemical field, particularly a kind of ultraviolet-curing paint that is used for automobile, the not flavescence of motorcycle external member surface coating layer.
The present invention further improves in the patent of first to file the applicant, one of series of studies that to be ultraviolet-curing paint use in automobile, motorcycle external member surface-coated.Ultraviolet-curing paint is not only energy-efficient on using, and product is pollution-free, and the formed paint film of coating also has tough and hard wear resistant, advantage such as high temperature resistant, corrosion-resistant.Ultraviolet-curing paint is applied to automobile, motorcycle external member surface Lacquer finish, improved the apparent mass of automobile, motorcycle external member greatly.Denomination of invention is " ultraviolet light cured paint specially for motorcycle ", application number is 99115412.6, and denomination of invention is " ultraviolet light cured smell-less paint specially for motorcycle ", application number is that 99115411.8 patent application has disclosed and is applied in the lip-deep ultraviolet-curing paint of motorcycle external member, but in the paint composite of mentioning in the above-mentioned patent application specification Epocryl is arranged, and Epocryl, or flavescence to a certain degree takes place in the epoxy methacrylates resin when UV-irradiation is solidified, and is not suitable for automobile, the coating of white workpiece on the motorcycle.
The ultraviolet-curing paint of not flavescence when the object of the present invention is to provide a kind of curing, and it is applied to the surperficial Lacquer finish of automobile, motorcycle external member, in order to wear-resisting, anti-wiping, oil resistant, the ageing-resistant and acidproof rain erosion performance that improves automobile, motorcycle external member.
Technical solution of the present invention is: adopt aliphatics or cycloaliphatic polyurethane acrylate resin, aliphatics or cycloaliphatic polyurethane methacrylate resin, with aminoacrylic acid resin or methylamino acrylic resin as reactive oligomers, do not adopt in existing the composition the easily Epocryl of flavescence.Coating composition of the present invention is as follows, by weight percentage:
