Problems solved by technology

Ordinary UV roller coating white primer is only 20-25g / ㎡ after laser roller coating, and the surface of the rolled plate is pitted, which makes the subsequent sanding process unable to go on and cannot meet the requirements of the laser roller. Thick coating (35~45g / ㎡) and smooth surface close to mirror effect
The reason is that the white primer on the ordinary UV roller cannot completely wet into the groove of the laser engraved laser roller, and after the laser roller is coated on the board, the paint cannot be quickly leveled on the board, so it is not suitable for the laser roller at all. coating machine

Abstract

The invention discloses a UV (ultraviolet) curing white primer for laser roller painting of woodware, which has high coating quantity and flat and bright coated surface. The UV curing white primer comprises 15-25 percent of bisphenol A epoxy acrylate, 15-25 percent of polyester acrylate, 1-10 percent of polyurethane acrylate, 8-15 percent of tripropylene glycol diacrylate, 3-8 percent of reagent type hydroxyethyl acrylate, 10-25 percent of trimethylolpropane triacrylate, 5-8 percent of photoinitiator, 0.2-0.4 percent of wetting dispersant, 0.2-0.4 percent of anti-settling agent, 8-15 percent of talcum powder and 10-20 percent of titanium dioxide. The UV curing white primer has the characteristics that after laser roller painting construction is ended, the coating amount is capable of reaching 35-45g / m<2>, the coated surface is flat and bright, the covering power is stronger than that of a common roller painting UV white primer, and the semi-curing repainting between paint films is not required to be ground, and the like. When being used for performing coating, the UV curing white primer has the advantages of time and labor saving, high fullness of products, and less loss of a machine.

Description

technical field [0001] The invention relates to a UV (ultraviolet light) curing primer applied to woodware, in particular to a special white primer for laser roller coating and its preparation and application method. Background technique [0002] At present, the roller coating methods commonly used in the field of UV wood paints are all coated with ordinary rubber rollers or silicone rollers with smooth surfaces. This method has a small amount of one-time coating, and the average coating amount is 15-20g / ㎡ , and the surface effect is relatively rough and pockmarked. The larger the coating amount, the more obvious the roll pattern on the surface is, the more difficult it is to sand. Multiple paint films can be sanded flat to no bright spots. This method not only increases the loss of the abrasive belt, but also because too much paint film is sanded off, the fullness of the finished product will become poor. Therefore, it is necessary to If you want to meet the customer's req...
