Description

Technical Field

[0001] This patent relates to an explosion-proof, antibacterial, and heat-insulating film for automobiles. Background Technology

[0002] With the increasing number of private cars, everyone frequently comes into contact with vehicle windows in daily life, and bacteria or viruses can easily accumulate on these windows. The bacteria and viruses on the window surfaces within the enclosed space of a car for extended periods can pose a health hazard to passengers, especially in public transportation (buses, taxis, and ride-hailing vehicles). Utility Model Content

[0003] The specific technical solution is as follows:

[0004] An explosion-proof and antibacterial heat insulation film for vehicles, characterized in that it comprises an antibacterial coating (1), a PET base layer (2), an adhesive layer (3), and a release film layer (4); wherein the antibacterial coating (1) is a micro-grooving coating with a thickness of 10-11 micrometers coated on the PET base layer (2) on the side of the vehicle interior occupants; the adhesive layer (3) is an acrylic pressure-sensitive adhesive coating coated on the PET base layer (2) on the side of the vehicle window; and the release film layer (4) is attached to the adhesive layer (3).

[0005] Furthermore, the PET base layer (2) contains heat-insulating and UV-resistant masterbatch formed by one-time film stretching.

[0006] Furthermore, the adhesive layer (3) has a thickness of 8 micrometers.

[0007] Furthermore, the thickness of the release film layer (4) is 23 micrometers.

[0008] Beneficial effects

[0009] This gives the parts of the car's explosion-proof and heat-insulating film that come into contact with the human body antibacterial (antiviral) properties, reducing the harm of bacteria and viruses on the window surface to passengers in the long-term enclosed space of the car. It provides a healthier and more durable riding environment, especially for public transportation (buses, taxis, and ride-hailing vehicles), the elderly, children, and people with weakened immune systems. Depending on the usage environment, the antibacterial (antiviral) properties are long-lasting. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of the car film of this patent. Detailed Implementation

[0011] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0012] like Figure 1 As shown, the car film of this patent includes: an antibacterial coating 1, a PET base layer 2, an adhesive layer 3, and a release film layer 4; wherein the antibacterial coating 1 is a micro-recessed coating with a thickness of 10-11 micrometers coated on the inner side of the PET base layer 2; the adhesive layer 3 has a thickness of 8 micrometers; and the release film layer 4 is attached to the adhesive layer 3 with a thickness of 23 micrometers.

[0013] Among them, antibacterial coating 1 is a micro-recessed coating with a dry film thickness of 10-11 μm. After coating, it is preheated to 80℃-100℃ for 1-3 min and then passed through a UV high-pressure mercury lamp with an energy of 300-400 mj / cm2 and a light intensity of 100-150 mw / cm2. It is coated on the PET substrate on the passenger side of the vehicle interior.

[0014] PET base layer 2 is made of high-strength, high-transparency PET polyester and pigment melt extrusion biaxially oriented polyester film, containing heat-insulating and UV-resistant masterbatch, and is formed by one-time film stretching, with a dry film thickness of 54μm.

[0015] Adhesive layer 3, acrylate pressure-sensitive adhesive coating, 8μm thick, is applied to the window side of PET base layer 2.

[0016] Release film layer 4: Attached to the mounting adhesive layer, 23μm thick, and removed after installation.

[0017] It should be noted that the above embodiments are only used to illustrate the technical solutions of this patent, and not to limit them; although this patent has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this patent.
