[0023] See also Figure 1-4In the utility model, a wear-resistant and waterproof PU adhesive protective film tape comprises a substrate 1, a bonding layer 2 is fixedly connected to the bottom surface of the substrate 1, a wear-resistant layer 3 is fixedly connected to the upper surface of the substrate 1, and a waterproof layer 4 is fixedly connected to the upper surface of the wear-resistant layer 3. Through the action of the wear-resistant layer 3, the waterproof layer 4 and the outer protective layer 5, the wear-resistant layer 3 can resist the physical wear on the surface of the equipment, the waterproof layer 4 can prevent rainwater from penetrating into the inside of the equipment, and can improve the waterproofness of the protective film to prevent rainwater from damaging the performance of the equipment. The outer protective layer 5 can better protect the equipment, thereby extending the service life of the equipment, which not only helps to maintain the smoothness of the surface of the equipment, reduce the conductivity of the surface of the equipment, and reduce signal attenuation, thereby improving the operating performance of the equipment, but also can reduce the occurrence of scratches and water stains on the surface of the equipment, so that the equipment maintains a beautiful appearance and enhances the image of the equipment. Since the protective film has good wear resistance and waterproofness, it can maintain good performance even when used in harsh outdoor environments.

[0024] The upper surface of the waterproof layer 4 is fixedly connected to an outer protective layer 5. The outer protective layer 5 can improve the protective effect of the product on the equipment.

The bottom surface of the bonding layer 2 is fixedly connected to a pressure-sensitive adhesive layer 10. The pressure-sensitive adhesive layer 10 can generate viscosity when it is subjected to pressure during pasting. Pasting the bonding layer 2 on the surface of the equipment can improve the fit between the device and the equipment.

[0025] The bottom surface of the waterproof layer 4 is fixedly connected with a polyurethane glue layer 8, and the bottom surface of the polyurethane glue layer 8 is fixedly connected with a fluororubber layer 9. Through the cooperation of the polyurethane glue layer 8 and the fluororubber layer 9, the waterproof effect of the device can be further improved.

The outer surface of the wear-resistant layer 3 is fixedly connected with an outer anti-wear layer 11. The material of the outer anti-wear layer 11 is silicone rubber. Through the setting of the outer anti-wear layer 11, the structural strength of the device can be improved, and the wear resistance of the protective film can be further improved to prevent the surface of the equipment from being scratched or worn.

[0026] The working principle of the utility model is:

[0027] When in use, first move this product to the place of use, then take out the wear-resistant and waterproof PU adhesive protective film tape from the packaging bag, and then tear off the release paper 7 from the pressure-sensitive adhesive layer 10. During the tearing process, keep the bonding layer 2 flat, then face the wear-resistant layer 3 of the bonding layer 2 upwards, align the bonding layer 2 with the pressure-sensitive adhesive layer 10 on the surface of the equipment, and gently stick the bonding layer 2 and the pressure-sensitive adhesive layer 10 on the surface of the equipment. After sticking the tape, use a scraper to expel the air between the protective film and the surface of the equipment, so that the protective film fits more closely to the surface of the equipment. When in use, because this product can improve its wear resistance and waterproofness through the effects of the wear-resistant layer 3, the waterproof layer 4 and the outer protective layer 5, it can thereby extend the service life of the equipment.
