Beneficial effect of the present invention: coat with lacquer in a kind of vacuum plating ultraviolet light polymerization, it comprises following raw materials by weight percent: Hydroxylated acrylic resin 10%~20%, polyurethane acroleic acid 25%~35%, thermoplastic acrylic resin 15%~20%, vinyl acetic monomer 15%~25%, N-BUTYL ACETATE 10%~15%, isopropylcarbinol 8%~15%, nano dye 3%~10%, trigger for optical solidification 3%~5%, auxiliary agent 1%~3%; The present invention is solidified quick and is had good wear resistance, resistance to soiling, anti-hard thing scratch resistant, the glossiness height, volatility is low, environment friendly and pollution-free, can extensively spray and be used for electronics or electric equipment products, cosmetics containers etc., can make the outward appearance of product more attractive in appearance, strengthen whole adhesive force of coatings, strengthen its scratch resistance, wear-resisting and anti-pollution characteristic.In addition, this product can be used for auto lamp, electric hair clip, electric iron etc., has resistance to elevated temperatures.
Embodiment:
The present invention is further illustrated with specific embodiment below, but the present invention is not subjected to the qualification of following embodiment.
Hydroxy acrylate has high adherence, high-flexibility, and the resin low temperature adaptability that has is good, and ferrous metal sticking power is good, corrosive nature is good.
Maximum characteristics of urethane acrylate and performance are: viscosity is low, can make oligopolymer again, also can make reactive thinner and use, and smell is low.If require curing speed fast, can select the higher slightly resin of functionality to strengthen sticking power simultaneously, system has excellent weathering resistance after the film forming, and snappiness and elongation at break have favorable chemical resistance and environmental compatibility, and ply adhesion is good.
