Problems solved by technology

Due to the complex environment in which the high-speed rail operates, some dirt (such as rain spots, dust, bird droppings) is difficult to clean off, which increases the difficulty of cleaning work
[0005] 2. Damaged paint surface
However, the better the hydrophilicity, the easier it is for the membrane to absorb water, including the dust in the water, which brings inconvenience to the cleaning work.

Embodiment 1

[0032] The stain-resistant protective film for rail cars comprises an adhesive adhesive layer, a base material layer and a stain-resistant layer arranged in sequence, wherein the process of setting the stain-resistant layer on the base material layer is: coating the stain-resistant layer on the base material layer , dried at 60-80°C for 1-2 minutes, and then cured in a UV LED light box with a curing light intensity of 800-1500mw / cm 2 , The curing time is 1-3 seconds. Among them, in order to facilitate the transportation of the produced protective film, a release film is provided on the other side of the adhesive layer, and a transparent protective film is compounded on the top of the stain-resistant layer to prevent damage. When the installation is in place, remove the release film and transparent protective film . Its structure is as figure 1 As shown in the figure, the base material layer 1; the stain-resistant layer 2; the transparent protective film 3; the pressure-sensi...

Abstract

The invention discloses an anti-fouling protective film for lacquer of a rail traffic vehicle. The protective film comprises a base material layer, an anti-fouling layer is arranged on one side of thebase material layer, the water contact angle of the anti-fouling layer is larger than 70 degrees, the other side of the base material layer is provided with a bonding glue layer bonded with the lacquer of the rail traffic vehicle, and release force of bonding glue is larger than 15 N / 25 mm and smaller than 30 N / 25 mm. The protective film adopts a hydrophobic coating and has a hydrophobic effect similar to surface layers of lotus leaves, thus ordinary fouling has difficulty in adhering to the surface layer of the protective layer, and cleaning is convenient; the anti-fouling protective film further has the function of naturally repairing slight scratches in the surface of the protective film, and the lacquer can be protected to the utmost extent; and the anti-fouling layer of the protective film is dried and cured through a UV-LED photocuring process, the drying temperature can be decreased, using of a solvent in the coating process is reduced, and economical efficiency and environmental protection are achieved.

Description

technical field [0001] The invention belongs to the field of functional films, in particular to a stain-resistant protective film used for paint surfaces of rail transit vehicles. Background technique [0002] With the popularization of high-speed railways in China, as of the end of 2018, the total operating mileage of my country's high-speed railways exceeded 29,000 kilometers, and the operating mileage of high-speed railways exceeded two-thirds of the total mileage of high-speed railways in the world, ranking first in the world. The maintenance and maintenance of the paint surface of the rail car body has also become an important issue, that is, how to maintain and clean the paint surface of the car body easily and keep the train beautiful. [0003] Defects and deficiencies of current rail car, especially high-speed rail body maintenance cleaning technology: [0004] 1. Inconvenient to clean. At present, high-speed rail trains must be cleaned and overhauled after running...
