[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the high-viscosity insulating PE self-adhesive film adopts a novel structural design, which not only provides a surface protection structure to prevent the PE self-adhesive film body from being scratched and damaged by external objects, but also strengthens the PE layer to improve the overall structural strength, ensuring that the film body can provide stable insulation protection for the attached objects;

[0024] The composite PE base layer 1 of this example is composed of a PE layer 101 and a reinforcement layer 102. The reinforcement layer 102 is provided at the bottom of the PE layer 101. The above structural design greatly improves the overall structural strength of the composite PE base layer 1, ensuring that the membrane can be used stably for a long time.

[0025] The PE layer 101 and the reinforcement layer 102 have the same thickness. The reinforcement layer 102 is made of polyester fiber. The above structural design ensures that the overall structural strength of the composite PE base layer 1 is sufficient.

[0026] The thickness of the thermal insulation layer 2 is not less than that of the polyurethane electrostatic adsorption layer 3. The material of the thermal insulation layer 2 is expanded polystyrene board. The above structural design enables the thermal insulation layer 2 to effectively isolate the outside world and prevent the polyurethane electrostatic adsorption layer 3 from losing its adsorption effect due to high temperature.

[0027] The composite insulating layer 5 includes a silicone resin layer 501 and an epoxy resin layer 502 . The epoxy resin layer 502 is provided on the top and bottom surfaces of the silicone resin layer 501 . The above structural design effectively enhances the insulating effect of the film body.

[0028] The epoxy resin layer 502 is symmetrically distributed about the center of the silicone resin layer 501 . The thickness of the silicone resin layer 501 is greater than that of the epoxy resin layer 502 . The above structural design not only ensures the insulation effect, but also has a certain protection effect.

[0029] The thickness of the top covering film 6 is not less than half of the thickness of the thermal insulation layer 2 . The material of the top covering film 6 is ABS. The above structural design ensures that the structural strength of the top covering film 6 is sufficient to stably protect the inner structure.

[0030] Insulation protection strips 7 are arranged at equal intervals on the top surface of the top covering film 6. The top surface of the insulation protection strips 7 is set to an arc surface. The material of the insulation protection strips 7 is rubber. The above-mentioned mechanism design not only has a certain buffering protection effect, but also has a certain insulation effect.

[0031] Working principle: After the polyurethane electrostatic adsorption layer 3 is attached to the surface of the protected object, the top covering film 6 and the insulating protection strip 7 can protect the film body from the surface to prevent damage to the internal structure. The composite insulating layer 5 greatly improves the insulation effect. The overall structural strength of the composite PE base layer 1 is sufficient and can be used stably for a long time. The thermal insulation layer 2 can greatly reduce the impact of the external temperature on the polyurethane electrostatic adsorption layer 3, and prevent the polyurethane electrostatic adsorption layer 3 from losing its adsorption effect due to high temperature. This is the working principle of the high-viscosity insulating PE self-adhesive film.
