Background
Compared with a single-layer plastic film, the multi-layer plastic film has more functions and purposes after being compounded, and is widely applied to the fields of packaging, printing, displaying, decorating and the like. The multilayer plastic functional film represented by the polarizer is widely applied in the field of electronic display devices such as liquid crystal displays and liquid crystal televisions, and the amount of the multilayer plastic functional film is increased along with the progress of times, and meanwhile, the waste polarizer generated is also in urgent need of recycling treatment. The existing abandoned polaroids mainly come from leftover materials and abandoned electronic display equipment generated by cutting in the production process of the polaroids. The polarizer structure is formed by sequentially bonding five film layers of a release film/cellulose Triacetate (TAC)/polyvinyl alcohol (PVA)/TAC/protective film, wherein the release film and the protective film mainly comprise polyethylene terephthalate (PET) film materials. The added value of the PET film in the waste polaroid is high, and the PET film is an important industrial raw material, but because the PET film contains a large amount of adhesive to tightly adhere the multilayer films, the physical and chemical properties of the films are close to each other, the peeling, sorting and adhesive removing difficulty of the multilayer films is extremely high, so that the waste polaroid is difficult to recycle, the waste polaroid is directly incinerated at present, the treatment cost is high, the environmental pollution is large, and the resource waste is serious. Market research shows that 10 ten thousand tons of cutting scraps are only discarded from iodine-based polarizers every year, and the recycling value of the polarizers exceeds thousands of yuan every year. In addition, the polarizer also contains valuable materials such as TAC, PVA, iodine and the like, which can be recycled, and in addition, a large number of polarizers in the waste display equipment have considerable comprehensive recycling value and prospect. Therefore, it is necessary to develop a comprehensive recycling technology of waste multi-layer plastic films.
