[0025] Referring to Figure 1 The utility model provides a technical scheme: a stable protective film, including protective film body 1, protective film body 1 includes first composite film 15 and second composite film 16.

[0026] The overall specific setting and effect are described below.

[0027] In the embodiment: first composite film 15 and second composite film 16 are provided with glue 11, and first composite film 15 and second composite film 16 are glued by glue 11, and the inside of glue 11 is filled with braided layer 17, and braided layer 17 is a netted nylon fiber layer, and the lower surface of second composite film 16 is glued with base paper 12. The netted nylon fiber layer has high use intensity and wear resistance, and is used as braided layer 17 to improve the tear resistance of protective film body 1 during use, thereby improving the stability of the use of protective film body 1. The upper surface of first composite film 15 is provided with wear-resistant layer 14, and wear-resistant layer 14 is a polytetrafluoroethylene layer. The wear-resistant layer 14 made of polytetrafluoroethylene layer has excellent wear resistance, high temperature resistance and chemical stability, improves the wear resistance of protective film body 1 during use, and further improves the stability of the use of protective film body 1.

[0028] Specifically, the lower surface of base paper 12 is uniformly provided with a plurality of tear seams 13. The base paper 12 can be torn into a strip structure by means of tear seam 13, and after tearing off a strip of base paper 12, the corresponding second composite film 16 is immediately adhered, which can realize the timely extrusion of bubbles when the second composite film 16 is adhered. First composite film 15 and second composite film 16 are provided with a plurality of grooves 18 on the side close to each other. By setting the grooves 18, the stability of the glue 11 filled in the grooves 18 and the inside of the first composite film 15 or the second composite film 16 is improved, and the anti-offset effect during use of the first composite film 15 and the second composite film 16 is avoided.

[0029] The recess 18 is a semispherical cavity structure. The semispherical structure recess 18 facilitates the extrusion manufacturing work of the recess 18 on the protective film body 1. The protective film body 1 is provided with a through hole 2 in the surface, and the through hole 2 is an elliptical structure. By arranging the through hole 2 on the protective film body 1, not only the heat dissipation effect in the use process of the product is facilitated, but also the friction between the hand and the product is increased, and the use performance of the protective film body 1 is further improved.

[0030] The working principle is that the net nylon fiber layer has high use strength and wear resistance, and is used as the woven layer 17 to improve the tear resistance of the protective film body 1 in the use process, thereby improving the stability of the use of the protective film body 1. The woven layer 17 is compounded between the first composite film 15 and the second composite film 16 through the colloid 11, thereby further improving the stability of the use of the whole protective film body 1. The wear-resistant layer 14 made of polytetrafluoroethylene has excellent wear resistance, high temperature resistance and chemical stability, thereby improving the wear resistance of the protective film body 1 in the use process, and further improving the stability of the use of the protective film body 1. When the bottom paper 12 needs to be torn to paste the second composite film 16, the bottom paper 12 can be torn into a strip structure by means of the tear seam 13. After one strip of the bottom paper 12 is torn, the corresponding second composite film 16 is pasted, the bubble can be extruded in time when the second composite film 16 is pasted, thereby further improving the stability of the pasting of the second composite film 16. By arranging the recess 18, the stability of the colloid 11 filled in the recess 18 and the first composite film 15 or the second composite film 16 is improved, the misalignment of the first composite film 15 and the second composite film 16 is avoided, and the stability of the use of the first composite film 15 and the second composite film 16 after compounding is further improved. The semispherical structure recess 18 facilitates the extrusion manufacturing work of the recess 18 on the protective film body 1. By arranging the through hole 2 on the protective film body 1, not only the heat dissipation effect in the use process of the product is facilitated, but also the friction between the hand and the product is increased, and the use performance of the protective film body 1 is further improved.
