Abstract

The invention relates to a preparation method of a high-toughness impact-resistant PET protective film, and belongs to the technical field of protective film preparation of electronic products. According to the preparation method, calcium hydroxide is used as a raw material, sucrose is adopted as a crystal form guiding agent, and carbon dioxide is introduced so as to produce a nano calcium carbonate material; and the nano calcium carbonate is modified by using distearyloxy isopropyl aluminate and octadecylamine, toughening treatment is conducted on the polymer by selecting methyl methacrylate,butadiene and styrene ternary polymer and utilizing the rigidity of the nano calcium carbonate and large quantities of chemical bonds which are formed among molecules of the PET protective film underthe action of the aluminate coupling agent; the obtained copolymer has a core-shell structure, and the shell phase is composed of methyl methacrylate which has large hardness and can be miscible withmethyl methacrylate in the polymer; and therefore, the hardness and impact resistance of the PET protective film can be further enhanced, and the toughness and mechanical strength of the PET protective film can be enhanced remarkably, and the preparation method has a broad application prospect.

Description

technical field [0001] The invention relates to a preparation method of a high-toughness and impact-resistant PET protective film, belonging to the technical field of preparation of protective films for electronic products. Background technique [0002] At the beginning, PET materials were mainly used in industry. For example, the Coca-Cola plastic bottles we see today are made of PET. Mainly used for surface protection of mobile phones and other electronic products, glass surface protection and heat insulation, UV protection, etc. Because the PET material has the advantages of light weight, good transparency and gas barrier, non-toxic, tasteless, etc., it has achieved rapid development. Since the 1990s, the production and application of plastic packaging materials have sprung up like mushrooms, and with the maturity of touch technology, PET materials are naturally used on various LCD screens, which is today's PET protective film. [0003] With the rapid development of IT ...
