[0036] Carry out coating preparation according to the coating formula of table 1, concrete preparation process is as follows:
[0037] (1) Mix the antifouling resin, UV-curable monomer, photoinitiator and film-forming aid, and stir at 500-1000r / min for 5-10min until uniformly mixed to obtain a primary mixture;
[0038] (2) Under stirring conditions, add water-based UV-curable oligomer to the primary mixture, stir at 500-1000r / min for 10-15min until evenly mixed, then add deionized water, wetting agent and leveling agent, Disperse at 1000-3000r / min for 0.5-1h, filter and discharge to obtain the water-based UV-curable anti-fingerprint coating.

The invention discloses a water-based ultraviolet-curing anti-fingerprint coating and a preparation method thereof, and belongs to the technical field of coating processing. The coating comprises, bymass, 12-22% of anti-staining resin, 12-44% of an aqueous ultraviolet-curing oligomer, 5-20% of an ultraviolet-curing monomer, 1-5% of a photoinitiator, 0.05-0.2% of a leveling agent, 0.05-0.2% of a wetting agent, 0-10% of a film forming additive and 20-69% of deionized water. The water-based ultraviolet-curing anti-fingerprint coating prepared through the certain preparation method by adopting the fluorine-containing or silicon-containing anti-staining resin and the aqueous ultraviolet oligomer as a main body adopts water as a dispersion medium, has the characteristics of low odor, non-flammability, low VOC content, washability and the like, reserves the advantages of short curing time, high production efficiency and low energy consumption of UV coatings, and meets the requirements of green and environmental laws and regulations; and a coating layer obtained by using the coating has the advantages of excellent anti-fingerprint effect and strong durability.
Description
technical field [0001] The invention relates to the technical field of paint processing, in particular to a water-based ultraviolet light curing anti-fingerprint paint and a preparation method thereof. Background technique [0002] In the past 20 years, 3C (Computer, Communication, and Consumer Electronics) electronic products have developed rapidly in China. From daily luxury goods to daily consumer goods, and then to daily consumables, their consumption is increasing. Internal competition is also getting stronger. From the comprehensive consideration of cost and performance, the shell of 3C products mostly uses plastic substrates, and the corresponding coating effect has also received widespread attention. The beautiful appearance, comfortable feel and durable performance are more and more favored by consumers. Among them, since mobile phones, tablet computers and other electronic products have been completely transformed into touch operation, the body and screen surface ...
