Protective film on automobile surface and its spraying fluid

Abstract

The invention discloses automobile surface protective film, comprising base film, soundproof film, rigid film and peelable protective film which are combined sequentially to the surface of an automobile by spraying, wherein the protective film is formed via the specific steps: coating the surface of the automobile with the base film, combining a soundproof colloid layer to the surface of the basefilm after the base film forms and dries, and air-drying at normal temperature; after the colloid air-dries, coating the surface of the colloid with a rigid spraying liquid layer, air-drying to obtainthe rigid film, spraying a peelable protective coating layer to the surface of the rigid film, and air-drying at normal temperature to obtain the protective film. The automobile surface protective film has great soundproof capacity; the rigid film and the peelable protective film provide great impact resistance via double action, and surface scratch can be effectively avoided for the automobile;when the peelable protective film is scratched, further protection can be provided directly via the rigid film, so that the surface of the automobile is never damaged; the scratched peelable protective film can be replaced by direct peeling and can be peeled completely and replaced conveniently.

Description

technical field [0001] The invention belongs to the field of automobile production, and relates to an automobile surface protective film and a spraying liquid used therefor. Background technique [0002] With the development of people's life, cars have gradually entered every household. For car lovers, the performance of the car and the decorative performance of the surface are very important. For the existing vehicle surface, it is usually painted after the surface of the car is painted. Wax, the surface protection of the vehicle is achieved through the wax mold, but the impact resistance of the wax mold is poor, and the direct action of the wax mold on the paint film will cause serious damage to the surface of the car after the wax mold is damaged, and it needs to be re-waxed after the wax mold is damaged , more troublesome, at the same time when being subject to a huge impact, the impact resistance of the vehicle is low, causing the deformation and damage of the car to ca...

[0003] At the same time, the sound insulation performance of vehicles is particularly important. At present, the automobile industry uses sound insulation pads, most of which are made of single-layer felt uniform thickness materials, which can obviously absorb and attenuate noise. However, the installation of sound insulation pads is cumbersome and the process is complicated.
