The UV of light trigger TPO absorbs crest at 300nm～380nm, all has stronger activity than other light trigger, is fit to thicker and colored coating.The mass fraction of TPO mainly is to decide according to the content of resin between 4～6, when content is less than 4, can cause the paint film deep layer solidify bad, thereby influence performance, be not little more than the improvement of 6 pairs of solidification effects.
9,006 six functionality polyurethane acrylic resins have the fast characteristic of speed of response, and the deep layer that more is easy to do in coloured system is solidified, and the performance of product is played a decisive role.Content has when low and solidifies bad problem, can influence application property when content is high.
CAB381-20 is 20 seconds cellulose acetate butyrate resins of Yi Shi Man, can well help the orientation of aluminium-silver slurry and the viscosity of raising crude oil, improve the wetting and application property of coating to material, only needing to add a spot of effective constituent just has effect preferably, so can be to not being solidified with too much influence.Its solution content of 20% is at 15～18 parts, and content is crossed low effect can not reach expection, and too high levels can influence the curing of coating.
5501 directed waxes are a kind of polyethylene wax slurries that Supreme Being Si Balongxin releases, and aluminium-silver slurry is had the intensive directional effect, and also only needing to add a spot of effective constituent just has better effects, uses with CAB381-20 and can play better effect.Its content is 15 parts～20 parts, DeGrain when content is low; Content Gao Shihui significantly increases cost.
D8975 is a flow agent, is the flow agent of a kind of perfluor of Noveon company, improves the surface effect of coating and to the wettability of material.
R972 is the aerosil of Degussa, is nano level material, and the ply adhesion in counterweight man-hour is helpful.Its content is 2 parts～4 parts, and it is not fine that content is crossed low effect, because it has certain extinction, so too high meeting influence gloss.
At coating in use, concrete operations can be opened coating rare to 9.5 seconds/NK-2# cup by 6: 2: 2 with ethyl acetate, butylacetate, propyl carbinol, be sprayed on the plastic cement materials such as ABS, ABS+PC or PC, 60 ℃ of preheatings are 10 minutes then, with (1000～1200) mj/cm
2Ultraviolet light polymerization can obtain UV colored paint coating rakish, excellent performance.
This coating is taken into account the advantage of UV coating and conventional solvent type coating, it is fast to have UV paint solidification speed, save the energy, cured product performance good, be suitable for advantage such as high-speed automated production, can resemble the arbitrarily various colors of allotment of conventional solvent type coating again, original multi-coating system is kept to the single coating system, can reduces whole cost.
The present invention still has multiple concrete embodiment, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
