Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1-2, the present utility model provides a tear-resistant film, comprising an upper film base layer 1 and a lower film base layer 2, specifically, the upper film base layer 1 and the lower film base layer 2 are base layers forming a film, that is, the base layers of the film are of a double-layer structure, the base layers can be one of PVC film and PE film, the toughness is good, in order to protect the surface layers of the upper film base layer 1 and the lower film base layer 2 facing the outside, and a manually-tearable film layer 8 is adhered to the surface of the upper film base layer 1 and the bottom of the lower film base layer 2, and is mainly used for protecting the surface of the film which is not used from abrasion.
The upper film basic unit 1 bottom is connected with glass fiber layer 3, it is connected with weaving stratum reticulare 4 to go up glass fiber layer 3 bottom, the lower film basic unit 2 top is connected with down glass fiber layer 5, down glass fiber layer 5 top is connected with down weaving stratum reticulare 6, goes up film basic unit 1 and lower film basic unit 2 and all is equipped with glass fiber layer and the weaving stratum reticulare that corresponds dual laminating, and glass fiber layer and weaving stratum reticulare all possess certain toughness, and mechanical strength is high, is difficult to tear at the in-process of pulling.
The copper wire mesh layer 7 is connected between the upper textile mesh layer 4 and the lower textile mesh layer 6, the copper wire mesh layer 7 is arranged at the middle position between the upper film base layer 1 and the lower film base layer 2, the copper wire mesh layer 7 can strengthen the hardness of the center, the copper wire mesh layer is formed by intersecting a first copper wire 701 which is transversely distributed and a second copper wire 702 which is longitudinally distributed, each intersecting position is provided with a copper sheet 703 which is loose-proof, the hollowed position of the copper wire mesh layer 7 can be filled with a filling layer to be aligned with a protection level, and the copper wire mesh layer 7 is prevented from being pulled and deformed or even torn no matter in any direction.
