Abstract

The invention discloses a preparation method of optical wear-resistant hardening coating composition and hard coated film thereof. The preparation method is characterized in that the optical wear-resistant hardening coating composition is composed of 20-35 parts of multifunctionality pre-polymerized resin, 10-25 parts of active acrylics compound, 2-5 parts of first auxiliary, 0.1-0.5 part of second auxiliary, 1-3 parts of photoinitiator and 50 parts of organic solvent; the method of the hard coated film comprises the following steps: coating the composition one side surface of an optical level polyester base film by adopting an intagliotype, passing through a drying channel in linear speed of 15-25m / min, wherein the drying channel temperature is as follows: the I section is 50-60 DEG.C, the II section is 70-80 DEG.C, the III section is 80-100 DEG.C, the IV section is 100-130 DEG.C, and the V section is 60-90 DEG.C; removing organic solvent, and curing the coating composition through ultraviolet irradiation to obtain the optical hard coated film; the hard coated film is used for manufacturing display devices of computer and mobile phone, film switches, household appliance surface, and decorative nameplate surface to play the touch-resisting effect.
