Problems solved by technology

However, during the storage and transportation of export cars, due to the complex climate environment in the sea area, a large amount of salt spray is dispersed in the air, and the chloride ions in the salt spray can penetrate the metal protective film and destroy the oxide film, thus causing deep pitting on the paint surface of the car
[0003] At present, my country mainly uses protective wax technology to protect cars going abroad, but the method of coating protective wax has defects such as complicated process, difficult removal, and short protection time; , the corrosion-resistant layer of the protective film and the base layer of the protective film, the base layer of the protective film and the paint surface of the car are prone to blistering or peeling off, resulting in the protective film not being able to effectively protect the paint surface of the car

Abstract

The invention discloses a protection film of a paintwork for a vehicle. The protection film comprises a corrosion resisting layer, a transparent film base, a pressure sensitive adhesive layer and a release film layer, the corrosion resisting layer is arranged on the right side of the transparent film base, the pressure sensitive adhesive layer is arranged on the wrong side of the transparent filmbase, and the release film layer is composited to the external surface of the pressure sensitive adhesive layer. A preparation method of the protection film of the paintwork for the vehicle comprisesthe following steps: 1, uniformly coating the right side of the transparent film base to form the corrosion resisting layer; 2, uniformly coating the wrong side of the transparent film base to form the pressure sensitive adhesive layer; and 3, compositing the release film layer on the external surface of the pressure sensitive adhesive layer. The protection film of the paintwork for the vehicle of the invention has the advantages of avoiding of phenomena of foaming, shedding, curling and the like of present protection films in a long-time protection process, excellent weatherability possessing, and excellent salt mist protection effect possessing.

Description

technical field [0001] The invention relates to a paint surface protection film for vehicles and a preparation method thereof, in particular to a paint surface protection film suitable for the export storage and transportation of cars and a preparation method thereof. Background technique [0002] During the general storage and transportation of cars, the use of protective film for paint surface protection is one of the effective methods for anti-ultraviolet, anti-scratch, corrosion resistance and anti-oxidation. However, during the storage and transportation of export cars, due to the complex climate environment in the sea area, a large amount of salt spray is dispersed in the air. The chloride ions in the salt spray can penetrate the metal protective film and destroy the oxide film, resulting in deep pitting of the car paint surface. [0003] At present, my country mainly uses protective wax technology to protect cars going abroad, but the method of coating protective wax ...
