DETAILED DESCRIPTION

[0025] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the automotive glass protective TPU film with repair and anti-fouling functions of the utility model in conjunction with the accompanying drawings.

[0026] See also Figure 1-4 The utility model discloses a TPU film for protecting automobile glass with repair and anti-fouling functions, comprising a film body 1, an adhesive layer 2 is arranged below the film body 1, the adhesive layer 2 is made of PE material and has high softness, and then an adhesive for film pasting is applied on the upper surface, and first exhaust micropores 3 arranged at equal distances are provided on the upper surface of the film body 1, and the first exhaust micropores 3 are formed by rolling, and are very small and almost invisible to the naked eye, a repair layer 4 is arranged above the film body 1, and the repair layer 4 is formed by polymerization of methyl methacrylate monomer, and has high light transmittance and high temperature resistance, and second exhaust micropores 5 arranged at equal distances are provided on the upper surface of the repair layer 4, and a hydrophobic layer 6 is arranged above the repair layer 4, and the hydrophobic layer 6 is coated with materials such as fatty acid metal soap polyolefin silicone resin fluorocarbon polymer, silicone resin and fluorocarbon polymer, and has a good hydrophobic effect, and third exhaust micropores 7 arranged at equal distances are provided on the upper surface of the hydrophobic layer 6.

[0027] A first dot sheet 8 is fixedly connected to the left side of the upper surface of the membrane body 1, and a second dot sheet 9 is fixedly connected to the right side of the upper surface of the membrane body 1. Both the first dot sheet 8 and the second dot sheet 9 are opaque black. The first dot sheet 8 and the second dot sheet 9 can buffer the effect of thermal expansion and contraction on the automobile glass, change the speed of heat transfer, and make the automobile glass heated evenly, thereby minimizing the risk of glass cracking.

[0028] A release paper 10 is arranged below the membrane body 1, and the upper surface of the release paper 10 contacts the bottom surface of the adhesive layer 2. The release paper 10 is a kind of anti-sticking paper that prevents the prepreg from sticking and protects the prepreg from contamination. The release paper 10 is made of paper coated with an anti-sticking substance. The release paper 10 can protect the adhesive layer 2 from contamination and is also easy to tear off from the adhesive layer 2.

[0029] Two connecting pieces 11 are fixedly connected to the bottom surface of the release paper 10, and a pull strip 12 is fixedly connected to the upper surface of each connecting piece 11. Manually pinching the pull strip 12 and pulling the connecting piece 11 can facilitate the staff to tear the release paper 10 from the adhesive layer 2, ensuring the subsequent film laminating work can be carried out smoothly, which increases the convenience of using the release paper 10.

[0030] The bottom surface of the adhesive layer 2 is provided with horizontal grooves 13 arranged at equal distances, and the upper surface of the adhesive layer 2 is provided with vertical grooves 14 arranged at equal distances. Each horizontal groove 13 is connected to the vertical groove 14. The horizontal grooves 13 cooperate with the vertical grooves 14 to increase the adhesive storage capacity of the adhesive layer 2, thereby further improving the adhesion effect of the adhesive layer 2, so that the adhesive layer 2 is not easily loosened from the car glass due to too little adhesive.

[0031] A heat-insulating layer 15 is arranged above the membrane body 1, and the upper surface of the heat-insulating layer 15 is in contact with the bottom surface of the repair layer 4. The upper surface of the heat-insulating layer 15 is provided with fourth exhaust micropores 16 arranged at equal distances. The heat-insulating layer 15 is a plastic film filled with a metal layer inside, which can reflect infrared rays without affecting the line of sight, thereby achieving the purpose of heat insulation. The heat-insulating layer 15 can increase the overall heat-insulating effect of the membrane body 1, and the fourth exhaust micropores 16 can prevent the heat-insulating layer 15 from blocking the discharge of gas.

[0032] A shading layer 17 is arranged below the heat-insulating layer 15, and the bottom surface of the shading layer 17 is in contact with the upper surface of the film body 1. The upper surface of the shading layer 17 is provided with fifth exhaust micropores 18 arranged at equal distances. The inside of the shading layer 17 is coated with a special film to block light from penetrating the film body 1, forming a certain reflective layer to achieve a shading effect. The shading layer 17 can improve the shading performance of the automotive glass protection TPU film, and the fifth exhaust micropores 18 can prevent the shading layer 17 from affecting the smooth discharge of gas.

[0033] A rough layer 19 is provided below the membrane body 1, and the bottom surface of the rough layer 19 is in contact with the upper surface of the adhesive layer 2. The upper surfaces of the rough layer 19 and the adhesive layer 2 are both provided with sixth exhaust micropores 20 arranged at equal distances. The rough layer 19 can be rolled to form different plastic films with rough surfaces, which can increase the connection surface area between the membrane body 1 and the adhesive layer 2, thereby making it less likely for the membrane body 1 to be delaminated, further increasing the service life of the membrane body 1, and the sixth exhaust micropores 20 can prevent the rough layer 19 from affecting the gas discharge.

[0034] The working principle of the utility model is: first, the release paper 10 is torn off by pulling the strip 12 and the connecting piece 11, and then the film body 1 is adhered to the automobile glass by utilizing the viscosity of the adhesive on the adhesive layer 2. At this time, the film body 1 cooperates with the first exhaust micropores 3, the second exhaust micropores 5 and the third exhaust micropores 7, so that when bubbles are generated after the automobile glass protection TPU film is applied to the automobile glass, the staff only needs to use a plastic plate to scrape the film body 1 back and forth, and the bubbles can be gradually discharged outward through the first exhaust micropores 3, the second exhaust micropores 5 and the third exhaust micropores 7. In addition, since the apertures of the first exhaust micropores 3, the second exhaust micropores 5 and the third exhaust micropores 7 are very small and cannot be seen by the naked eye, the use effect of the TPU film can be guaranteed. In addition, the repair layer 4 can be briefly heated to enter a semi-fluid state and then quickly cooled. At this time, the repair layer 4 can automatically fill the scratches and dents, thereby realizing the self-repair function so that the automotive glass protection TPU film has the function of repairing bubbles and scratches and dents, which greatly increases the use effect of the automotive glass protection TPU film. In addition, the hydrophobic layer 6 can increase the hydrophobic effect of the film body 1 when it is used, so that water stains are not easily left on the automotive glass protection TPU film, thereby facilitating the user to clean the dust and impurities on the automotive glass protection TPU film, greatly increasing the anti-fouling ability of the automotive glass protection TPU film, making it easy to clean external dust and impurities from the automotive glass protection TPU film.
