Abstract

The invention relates to the technical field of optical films, particularly a preparation method of a composite optical precoating film. The preparation method comprises the following steps: (1) raw material preparation of coating liquid; (2) preparation of photodiffusant coating liquid: mixing one or more of 2-5-mu m acrylic microbeads, toluene and butanone, and stirring at normal temperature for 30 minutes while controlling the rotation speed at 500-900 rpm/minute; adding an UV resin and an acrylic pressure-sensitive adhesive, stirring at normal temperature for 30 minutes while controlling the rotation speed at 500-900 rpm/minute, thereby obtaining the photodiffusant coating material; (3) uniformly coating the photodiffusant coating material prepared in the step (2) on the back of an upper film, and covering a lower film, wherein a microgravure coating mode is adopted in the coating process, and a UV-curing/thermocuring combined mode is adopted to carrying out the curing operation in the coating process; and (4) testing. By using the unique formula technique system, the reasonable material proportioning is adopted, so that the manufactured optical precoating film has certain adhesive effects, and is suitable for the demands for manufacturing of various composite diffusion films and brightness enhancement films.

Description

technical field [0001] The invention relates to the technical field of optical films, in particular to a preparation method of a composite optical precoating film. Background technique [0002] At present, the domestic optical film market is growing rapidly, and various types of optical film manufacturing technologies for diffusion films, enhancement films, polarizing films, etc. are constantly innovating. The inevitable trend. Through compounding, the manufacturing cost can be reduced and the optical effect can be improved. One of the key success factors for compounding is the optical pre-coating film technology as a carrier. That is, on the premise that the optical effect of the pre-coating film remains unchanged, the pre-coating layer has a certain viscosity, so that the sticky pre-coating surface is bonded with another functional film to form the final composite functional film. At present, many functional film manufacturers in the domestic market are designing and dev...
