S220, the first surface that the anti-dazzle optical coating is uniformly coated on to the transparent plastic substrate, are placed in 50-90 DEG C of baking oven
Middle baking 30-60s forms Anti Glare Coatings by ultra-violet curing device by the anti-dazzle paint solidification；
S230, the second surface that the second adhesive is uniformly coated on to the transparent plastic substrate, are placed in 60-130 DEG C of baking oven
In, 1.5-2min is toasted, the second mucigel is formed；
S240, release film is fitted on second mucigel；
S250, protective film is fitted on the Anti Glare Coatings by the first adhesive, obtains anti-dazzle protective film.
10. the preparation method of anti-dazzle protective film according to claim 9, which is characterized in that prepare the anti-dazzle and apply
Material includes the following steps:
By the aqueous polyurethane high response monomer and the aqueous polyurethane hypoergia monomer and nanosphere cream
Liquid is blended, then adds defoaming agent, levelling agent, organic solvent and photoinitiator, and 20-40min is continuously dispersed in high speed disperser,
Standing and defoaming 20-40min obtains the anti-dazzle optical coating.
