According to the first step, firstly, selecting an explosion-proof layer and an ultraviolet heat insulation layer which are matched with each other according to the specification and the size of a film base layer, then coating a self-cleaning coating on the bottom end of the film base layer and the top end of the explosion-proof layer, then coating an anti-static coating on the top end of the film base layer, then coating a matte coating on the bottom end of the explosion-proof layer, and airing the film base layer and the explosion-proof layer after the coating is finished;
step three: is adhesively secured
According to the second step, firstly, the ultraviolet-proof heat-insulating layer is bonded to the upper surface of the film base layer through the bonding coating, then the explosion-proof layer is bonded to the upper surface of the ultraviolet-proof heat-insulating layer through the bonding coating, then the bonded film base layer, the ultraviolet-proof heat-insulating layer and the explosion-proof layer are positioned, and after the bonding coating is solidified, the explosion-proof film material in the dumb black mobile phone is prepared.
6. The preparation method of the explosion-proof membrane material in the dumb black mobile phone according to claim 5, characterized in that: in the first step, after the polycarbonate film is discharged from the calender, annealing treatment is performed on the polycarbonate film in an argon atmosphere at a constant temperature of 15O ℃, and then oxidation resistance treatment is performed on the polycarbonate film after annealing.
7. The preparation method of the explosion-proof membrane material in the dumb black mobile phone according to claim 6, characterized in that: after the polycarbonate film is subjected to anti-oxidation treatment, the surface of the polycarbonate film is polished, and then the polycarbonate film is cut into a specified size according to the processing requirement.
