The invention discloses an ultraviolet (UV) photocurable organic-inorganic nano material hybrid coating and a preparation method thereof. Polyurethane acrylate resin and a part of an active diluent are added into a dispersing cylinder; an inorganic nano material, a photoinitiator, a defoamer and a leveling agent which are well dispersed are gradually added at a rotating speed of 800-1000rpm; thenhigh-speed dispersing is carried out for 15-30min; and then viscosity is adjusted to 150-200cps by using the remaining active diluent, so that the UV photocurable organic-inorganic nano material hybrid coating is prepared. The coating not only has excellent super wear resistance, excellent adhesion and permeability, but also has simple preparation method, low cost and wide application range, and can be widely applied to many fields such as mobile phones, computers, household appliances, optical films, surface wear-resistant special plastics and the like. 本发明公开了一种UV光固化有机-无机纳米材料杂化涂料及制备方法，将聚氨酯丙烯酸酯树脂和部分活性稀释剂加入到分散缸中，在800～1
