The PET-film-bonded type transparent anti-UV projection screen includes a PET film layer, an adhesive layer and a transparent supporting layer which are sequentially stacked from top to bottom. The PET film layer is prepared by uniformly mixing PET resin, an antioxidant, a light stabilizer and a nanoparticle dispersion in a molten state, pre-crystallizing and drying the mixture, and then extruding, stretching and molding the mixture. The production method for the PET-film-bonded type transparent anti-UV projection screen includes preparing a nanoparticle dispersion; preparing a PET film; and performing coating and bonding the film.
PET 薄膜粘合型透明抗紫外线投影幕包括从上到下依次叠加的 PET 薄膜层、粘合剂层和透明支撑层。PET 薄膜层的制备方法是将 PET 树脂、抗氧化剂、光稳定剂和纳米粒子分散液以熔融状态均匀混合,对混合物进行预结晶和干燥,然后对混合物进行挤出、拉伸和成型。PET 薄膜粘合型透明抗紫外线投影屏幕的生产方法包括制备纳米粒子分散体;制备 PET 薄膜;以及对薄膜进行涂层和粘合。
