Abstract

The invention belongs to the technical field of protective films. The invention relates to a protective film material, in particular to a high-temperature-resistant stable protective film material anda preparation method thereof. The problem that an existing protective film is poor in high-temperature resistance is solved. According to the following technical scheme, the composition comprises thefollowing raw materials in parts by weight: 30-50 parts of polyethylene, 15-20 parts of calcium carbonate, 7-12 parts of plasticizer, 10 to 15 parts of polyvinyl chloride resin; 10-15 parts of epoxyresin, 2-7 parts of nano-silica, 1-6 parts of an antioxidant, 5-11 parts of polytetrafluoroethylene, 5-11 parts of acrylamide, 2-8 parts of magnesium stearate, 1-7 parts of polyurethane, 10-15 parts of polyetherimide, 5-10 parts of polyolefin, 1-6 parts of a heat stabilizer, 2-7 parts of polyester fibers, 1-6 parts of a scratch-resistant agent and 1-6 parts of a wear-resistant agent. The high temperature resistance can be effectively improved, the service life is prolonged, the strength is good, scratch resistance and wear resistance are achieved, and the preparation method is simple.

Description

technical field [0001] The invention relates to the technical field of protective films, in particular to a high-temperature-resistant and stable protective film material and a preparation method thereof. Background technique [0002] According to the application, the protective film can be divided into digital product protective film, car protective film, household protective film, food fresh-keeping protective film and so on. With the popularity of digital products such as mobile phones in China, protective film has gradually become a general term for screen protective films, and its functions in the field of screen protective films are also varied. The material has experienced more than 5 years of development from the earliest PP material to the current popular AR material, and has gradually been accepted by the majority of mobile phone groups. [0003] The existing protective film has poor high temperature resistance, so we propose a high temperature stable protective f...
