Problems solved by technology

For this kind of protective film coated with glue, the adhesive has the risk of transfer and peeling of the adhesive layer over time, causing the surface to be protected to be polluted and difficult to clean; the coated adhesive contains organic solvents, and there will be different degrees of solvent residues. Cause environmental pollution; and this kind of protective film needs to be produced through two processing procedures, and the production and processing costs will undoubtedly increase accordingly

Abstract

The invention provides an environmental-friendly protection film for an automobile. The environmental-friendly protection film is produced by co-extruding and casting an external layer, a middle layer and a bonding layer according to a certain thickness proportion to obtain a white protection film with the thickness of 40 to 100 micron. The environmental-friendly protection film mainly has the functions of dust prevention, mechanical damage prevention, ultraviolet prevention, bird dung pollution prevention, scraping prevention, oil pollution prevention, acid and alkali corrosion resistance, solvent corrosion resistance and the like.

Description

technical field [0001] The invention relates to the field of automobile environmental protection, in particular to an environment-friendly protective film for automobiles. Background technique [0002] Automobile protective film is mainly used to protect the surface of automobile paint and parts during automobile assembly and transportation. At present, there are many commercial protective films for automobiles on the market, most of which are foreign brands, such as Tesa protective film and Poli-film protective film in Germany, Sika protective film in Switzerland, and 3M protective film in the United States. It is produced by two processes, the first process is to produce the polyolefin protective film base material, and the second process is to coat the adhesive on the base material and then dry it. Domestic protective film patents, such as the self-adhesive protective film used to temporarily protect the vehicle paint surface mentioned in the patent application No. 20041...
