The invention discloses an ultraviolet light curing transparent priming paint and a preparation method and a use method thereof. The ultraviolet light curing transparent priming paint comprises the following components in percentage by weight: 20-30% of bisphenol A epoxy acrylate resin, 15-25% of polyester acrylate, 1-10% of urethane acrylate, 5-10% of reagent type hydroxyethyl acrylate, 10-20% of tripropylene glycol diacrylate, 12-25% of trimethylolpropane triacrylate, 4-6% of photoinitiator, 10-25% of filling powder and 0.4-0.8% of promotor. The ultraviolet light curing transparent priming paint is suitable for laser roller construction, has good grittiness and transparency, has the characteristics that sanding is not needed for semi-curing recoating between film layers and the like, and has thick coating performance and the performance that the surface is similar to a mirror surface, and compared with conventional roller coating, the coating weight is greatly increased, roller coating processes are saved, the priming paint is sanded by a sanding machine without large pressure and with a small number of sanded films, a workpiece has no bright spots, the fullness of a product is guaranteed, the product quality is improved, the loss of the machine is smallreduced, and the use amount of sanding belts is greatly reduced.

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.

The invention discloses ceramic pulp for photo-curable 3D printing and a preparation method and application of the ceramic pulp. The ceramic pulp includes ceramic powder, photo-curable resin, a photoinitiator and a dispersant, wherein the photo-curable resin comprises the components: in percent by mass, 10-60% of bisphenol A epoxy acrylate, 10-60% of trimethylolpropane triacrylate, 10-60% of tripropylene glycol diacrylate and 10-60% of isobornyl methacrylate. The rheological performance of the slurry can be adjusted through selection of reactive diluents with different functionalities and adjustment of the ratio of the diluents, needs of light curing molding can be met by the slurry, and degreasing and sintering are performed on a molded sample so as to obtain a high-density zirconia ceramic product with a relative density of up to 98.8%.

The invention discloses a weather-resistant leather finishing agent which comprises an aqueous polyurethane emulsion. The aqueous polyurethane emulsion is prepared by the following steps of: preparing a prepolymer by using isophorone diisocyanate (IPDI), polyethylene glycol (PEG3000), 1,4-butanediol (BDO) and dimethylolpropionic acid (DMPA) as raw materials; implementing an end-capping reaction and a neutralization reaction; adding tripropylene glycol diacrylate (TPGDA) and water for emulsifying; and adding an proper amount of triggering agents, thereby obtaining the acrylate-modified aqueous polyurethane emulsion. According to the weather-resistant leather finishing agent, the polyurethane is prepared by adopting the aliphatic isophorone diisocyanate (IPDI) which is excellent in photo-stability as the raw material and then modified by using acrylate, thus the problem of easy yellowing is fundamentally solved, and the weather resistance of the leather finishing agent is greatly improved.

The invention provides a UV coating used for stamped magnesium alloy. The UV coating mainly contains the following components: 43-62 weight parts of monomers, 3-7 weight parts of acrylate phosphate, 30-50 weight parts of polyurethane acrylic resin, 5-12 weight parts of aliphatic polyurethane acrylate, 6-10 weight parts of photoinitiator and 0.3-0.5 weight parts of levelling agents. The monomers include tripropylene glycol diacrylate and dipentaerythritol hexaacrylate. The photoinitiator is composed of 2-hydroxy-methoxyphenyl propane-1-one, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, 1-hydroxyl cyclohexylphenyl ketone and Ciba initiator. The levelling agent is an organic silicon or organic silane levelling agent. The UV coating has good adhesion on an oxide layer and a passivation layer of the stamped magnesium alloy and has good corrosion resistance.
