Abstract

The invention relates to a protective film and a preparation method thereof, in particular to an antibacterial and antistatic protective film for an automobile and a preparation method thereof. The antibacterial and antistatic protective film for the automobile is formed by processing a PVC (polyvinyl chloride) material, a modified TPU (thermoplastic polyurethane) material, an inorganic antibacterial agent and an antistatic master batch in a mass ratio of (80-100):(200-300):(1-3): (3-6); the modified TPU material is formed by processing the following raw materials in parts by weight: 50-60 parts of polyurethane, 10-20 parts of polyamide organic silicon thermoplastic elastomer, 6-8 parts of nano talcum powder and / or bentonite and 2-4 parts of plasticizer DEHP (Di 2-Ethyl Hexyl Phthalate). The antibacterial protective film for the automobile disclosed by the invention is good in product uniformity, unlikely to fade or edge-warp, good in conformability, long in service life and lower in processing cost.

Description

technical field [0001] The invention relates to a protective film and a preparation method thereof, in particular to an antibacterial and antistatic protective film for automobiles and a preparation method thereof. Background technique [0002] The protective film for automobiles is a high-performance film, light and transparent, with super toughness, which can effectively prevent scratches, pebbles and sand, and can also perfectly adhere to the surface of the car paint, so that the car paint and the air isolated. Effective anti-acid rain, anti-oxidation, anti-scratch, long-lasting protection of car paint. It is easy to maintain, reduces the cost of waxing the car body, and will not produce any toxic side effects and pollute the paint surface on the human body and nature. The protective film is colorless and transparent, and it can effectively brighten the car paint when it is pasted on the car paint, and can maintain the gloss for a long time. . [0003] At present, ther...
