[0019] The utility model is now further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model. The utility model is described in detail using structural schematic diagrams, etc. The schematic diagrams are only examples, and they should not limit the scope of protection of the utility model.
[0020] Please refer to Figures 1 to 3A high-strength PET protective film comprises a film core 1 and a film layer 2 wound around the film core 1. The film core 1 has a high load capacity, and the film layer 2 is wound around the film core 1 for ≥100 turns, so it can be used for a long time. A glue layer 3 is arranged on the side of the film layer 2 close to the film core 1, and the film layer 2 and the film core 1 are connected by the glue layer 3. The film layer 2 can be torn off from the film core 1 and pasted for use; in order to better exhaust air when it is attached to the surface of an object, the film layer 2 is provided with air holes, so that bubbles are not easily generated to affect the pasting effect; the film layer 2 comprises a first film layer 2a and a second film layer 2b stacked in parallel, and a mesh rib layer 2c is arranged between the two, the second film layer 2b is in contact with the glue layer 3, and its thickness is ≤ the first film layer 2a, and the first film layer 2a, the second film layer 2b and the mesh rib layer 2c are connected by adhesive.
[0021] For details, see Figure 3 The mesh rib layer 2c is woven from nylon wire, which has the characteristics of high strength, wear resistance and good resilience. It is made into a mesh lining between the first film layer 2a and the second film layer 2b, which effectively improves the strength of the PET protective film. Compared with the method of increasing the strength by adding a metal film layer, the use of a nylon mesh layer has the advantages of being non-conductive, light, low cost, and easy to recover after bending; the nylon wire is not perpendicular or parallel to the edge of the film layer 2, so the mesh formed in the middle is a parallelogram, and the air holes are evenly arranged in the mesh, with a diameter of 0.05-0.25 mm and passing through the upper and lower surfaces of the film layer 2.
[0022] The adhesive layer 3 is transparent silica gel, which is cheaper than acrylic glue; the cost of silica gel is relatively high, but it has better air discharge and temperature resistance, and good adsorption, so that the PET film of the utility model has high bonding strength.
[0023] In order to meet the requirements of different widths, multiple rows of overlapping through lattice holes 4 are equidistantly arranged on the film core 1 and the film layer 2, and the edge of the film layer 2 is parallel to the through lattice holes 4. When using a high-strength PET protective film of the utility model, the through lattice hole 4 from which the product is broken off for use is determined according to the required width, so that the same original long film core 1 can carry a variety of film layers 2 of different widths, which is easy to use and beneficial to saving resources.
[0024] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, implementing changes, modifications or additions should all fall within the protection scope of the utility model.
