Further, described silane coupler can be γ-methacryloxypropyl trimethoxy silane or MTES.
Further, described organic smooth shifting molecular calcein.Each component in calcein combination EVA adhesive film, converting different wavelength range ultraviolet light is visible ray, and the main light converting 300 nanometers to 400 nano-ultraviolet lights is 400 nanometers visible rays to 500 nanometers.
Further, the preparation method of described EVA adhesive film is: weigh EVA resin, antioxidant, peroxide, bridging agent, nucleator, coupling agent, conversion particles respectively according to above-mentioned weight, each component materials mixes, stably it is input in extruder, temperature is heated to 90-110 DEG C, extruded machine upper die head curtain coating extrusion, transfers to cooling roller cooling, prepares glued membrane after curling.
Beneficial effects of the present invention:
By with EVA resin as primary raw material, add various auxiliary agent and convert particle, melt processed shaping obtains encapsulation EVA adhesive film, this glued membrane can conversion solar light medium ultraviolet light be can absorbed visible ray, the light converting 300 nanometers to 400 nano-ultraviolet lights especially is 400 nanometers visible rays to 500 nanometers, not only increase photoelectric transformation efficiency, and can also delay to encapsulate the aging of EVA adhesive film.
