Description

Technical Field

[0001] This utility model relates to the technical field of automotive rearview mirrors and front window protective films, specifically a scratch-resistant, anti-fog, explosion-proof, and high-transparency protective film. Background Technology

[0002] Traditional automotive windshield and rearview mirror protective films use PET as the base material. Their main function is to protect the surface of car windows and rearview mirrors. They have neither anti-fog nor explosion-proof effects, the surface is not scratch-resistant, and the high transparency is not good, which can have a certain impact on human vision.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a scratch-resistant, anti-fog, explosion-proof, high-transparency protective film. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a scratch-resistant, anti-fog, explosion-proof, and high-transparency protective film.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant, anti-fog, explosion-proof, high-transparency protective film, comprising, from top to bottom, a super-hydrophilic anti-fog coating, a hardened anti-scratch coating, a substrate, a pressure-sensitive adhesive layer, and a release layer.

[0006] Furthermore, the substrate is either high-transparency PET or TPU.

[0007] Compared with the prior art, the beneficial effects of this utility model are: This utility model uses high-transparency PET or TPU as the base material. TPU has good tensile deformation performance, which is suitable for applying to flat and curved surfaces. In addition, due to its excellent flexibility, it also has a good explosion-proof effect, making it suitable for applying to car windshields. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] This utility model provides a technical solution:

[0013] Please see Figure 1 A scratch-resistant, anti-fog, and explosion-proof high-transparency protective film, using high-transparency PET or TPU as the base material, has a layer of hardened, super-hydrophilic, anti-fog coating on its surface. This coating makes it less prone to dust accumulation, and its super-hydrophilic surface prevents rainwater and car wash water from pooling and obstructing vision. The TPU has excellent flexibility, and when combined with a strong-holding adhesive layer, it effectively prevents shards from flying everywhere and causing injury when the window breaks, providing effective explosion protection. Specifically:

[0014] The hardened superhydrophilic anti-fog coating consists of an upper superhydrophilic anti-fog coating 1 and a lower hardened anti-scratch coating 2. The hardened superhydrophilic anti-fog coating is applied to a high-transparency PET or TPU surface. The coating process is anilox roller / micro-gravure coating. It is superhydrophilic, anti-fog, explosion-proof, scratch-resistant, and highly transparent. TPU is also easier to apply to curved surfaces and is easy to operate.

[0015] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
