Abstract

The invention relates to automobile konjac adhesive film and a preparation method thereof. The preparation method of the automobile konjac adhesive film comprises the steps of preparation of a konjac gel solution, deaeration of the konjac gel solution, preparation of a konjac gel film and metallization. By taking the konjac gulcomannan as a carrier and using other auxiliaries for assistance, the automobile konjac adhesive film disclosed by the invention is excellent in gel property, water retention, heat insulation property and light resistance, good in elasticity, high in flexibility and unlikely to be cracked. Compared with the traditional automobile film, the automobile konjac adhesive film disclosed by the invention has the effects of heat insulation, light resistance, good elasticity and high flexibility, the production materials are environment-friendly, and the automobile konjac adhesive film also has the advantages of low production cost, little environmental pollution, no harm to human body and the like. The safety and usability totally meet the national relevant standard requirements.

Description

technical field [0001] The invention relates to an automobile film and a preparation method thereof, in particular to an automobile konjac film and a preparation method thereof. Background technique [0002] With the popularity of cars, car film also came into being. Car film is mainly used for car body glass and car body surface, also called solar film or explosion-proof heat insulation film. Its main function is to block ultraviolet rays, block some heat, and prevent injuries caused by sudden glass bursts. At the same time, according to the one-way perspective performance of the solar film, it can achieve the purpose of protecting personal privacy. In addition, it can also reduce the damage of items in the car and personnel caused by ultraviolet radiation, and achieve the effect of saving fuel consumption at some levels. However, in the market now, the cheap car film has too single function and cannot play a good role; the fully functional car film is too expensive and t...
