S2, make the sub-light white of PET at the another side of PET base material;
S3, by quality accounting be 75% Polyvinylchloride, 8% fire retardant, 5.6% bridging agent, the stabilizing agent of 3.5%, the defoamer of 4% and 3.9% wetting agent join in solvent, stir and heat and obtain uniform thick shape liquid;
S4, thick shape liquid is coated on the surface of the sub-light white of PET by the mode that Electrostatic Absorption sprays.
Preferably, mould in the preparation method of projection screen in vain above-mentioned, described solvent is DMF.
Preferably, mould in the preparation method of projection screen in vain above-mentioned, described stabilizing agent is organic tin stabilizer, and described fire retardant is decabromodiphenyl oxide fire retardant.
Compared with prior art, the invention has the advantages that:
(1) projection screen luminance gain of the present invention is 0.92 times, and effective scattering angle is greater than 160 degree, has the advantage that resolution is high, colour reproduction good, visual effect is good.Scene plot face physical parameter stabilising decay is little, and the curtain plane materiel material of environmental protection is without any smell, and curtain surface evenness is good.
(2) adopt Electrostatic Absorption spraying to make paint particles by electric charge on High Rotation Speed band, be adsorbed under attractive interaction effect on base material, film evenly plentiful, strong adhesion, the high abrasion resistance of formation, improves the quality of film.And electrostatic spraying can increase exponentially utilization efficiency of coatings, improves execution conditions, environmental pollution drops to minimum.
