Using ultrasonic cleaning product surface, the bond strength of enhancing oil droplet and product surface.
Preferably, after ultrasonic wave cleaning, in product surface coating UV oil coatings, ultraviolet curing 30min.
Product surface coating UV oil coatings, the smoothness and flatness of product surface are improved, passes through oil droplet and UV oil coatings
Preferable adhesion, UV oil coatings are bonded with product surface large area, so that after oil droplet solidification more firmly, being not easy from product table
Emaciated face falls.
Preferably, UV oil coatings thickness is 15 μm~18 μm.
UV oil coatings are too thin, and oil droplet adhesive force deficiency, UV oil coatings are too thick, and UV oil coatings easily come off from product surface.
Preferably, the heating Wen Chengwei of step S5 baker：20 DEG C of heating 5min, according to 2 DEG C/min programming rate, rise
To 40 DEG C and 10min is heated, according to 5 DEG C/min programming rate, 55 DEG C is warming up to, toasts 30min.
It is segmented using low temperature, slow heat, the residual bubble in oil droplet is escaped oil droplet before oil droplet solidification, avoid gas
Bubble has little time to escape, and produces bubble point, influences the transparency after oil droplet shaping, causes product yield low.
Preferably, the vacuum in step S5 in baker is 0.07MPa.
Vacuum is 0.07MPa, accelerates the bubble effusion speed in oil droplet, reduces the heated baking time, avoid oil droplet old
Change.
Beneficial effects of the present invention：
1. by the way that viscosity is larger, the poor UV oil of mobility or PU oil or NC oil, sprayed through nozzle in drops in product
Surface, finally solidified, technique is simple.
2. using ultrasonic cleaning product surface, the bond strength of enhancing oil droplet and product surface.
3. product surface coating UV oil coatings, improving the smoothness and flatness of product surface, applied by oil droplet and UV oil
The preferable adhesion of layer, UV oil coatings are bonded with product surface large area, so that after oil droplet solidification more firmly, being not easy from product
Surface comes off.
4. being segmented using low temperature, slow heat, the residual bubble in oil droplet is escaped oil droplet before oil droplet solidification, keep away
Exempt from bubble to have little time to escape, produce bubble point, influence the transparency after oil droplet shaping, cause product yield low.
