Abstract

The invention relates to the technical field of films and discloses a high-transparency super-definition high-strength film and a preparation method thereof. The high-transparency super-definition high-strength film comprises the following raw material components in parts by weight: 60-70 parts of polyvinyl acetate resin, 2-5 parts of 2-tert-butyl-4-methyl-6 ethyl phenol, 3-5 parts of 3-methacryloxypropyltrimethoxysilane, 2-4 parts of 2-hydroxy-4-(octyloxy)benzophenone, 5-8 parts of sorbitan monolaurate, 1-3 parts of a fortifier and 3-6 parts of N,N'-ethylenedi(stearamide). The components areuniformly mixed and then added into an extruder to be subjected to piece casting, and a stretcher is adopted for stretching film forming. The high-transparency super-definition high-strength film is high in strength, transparency and definition, and has a very good protection effect on fragile products including glass, advertisement and the like.

Description

technical field [0001] The invention relates to the technical field of sticking films, in particular to a high-transparency, ultra-clear, high-strength sticking film and a preparation method thereof. Background technique [0002] There are many types of film on the market now, such as advertising film, screen film, glass film, etc. The function of these films is to protect advertisements, screens, glass and other items from being scratched; when the film is applied outdoors, such as glass film, advertising Sticking film, etc., in order to prevent the aging of the sticking film, it is necessary to carry out aging modification on the sticking film. [0003] Chinese Patent No. CN106633485 discloses a method for preparing a multifunctional advertising film, which includes the following steps: the raw material formula includes 100 parts of PVC, 15 to 30 parts of plasticizer, 2 to 4 parts of barium-zinc composite stabilizer, 0 to 40 parts of nanofiller, 0.5-1.5 parts of anti-UV53...
