[0019] The utility model is further described below in conjunction with the accompanying drawings.

[0020] like Figure 1A composite film based on electron irradiation strengthening and woven fiber support is shown, comprising a surface film layer 1 whose surface is strengthened by electron irradiation, a heat-bonded adhesive film layer 2, a woven fiber mesh layer 3, a first hot-melt adhesive layer 4, a waterproof cloth layer 5, a second hot-melt adhesive layer 6, a mesh layer 7, a self-adhesive layer 8 and a release film layer 9; wherein the surface film layer 1, the heat-bonded adhesive film layer 2, the woven fiber mesh layer 3, the first hot-melt adhesive layer 4, the waterproof cloth layer 5, the second hot-melt adhesive layer 6, the mesh layer 7, the self-adhesive layer 8 and the release film layer 9 are stacked in sequence.

[0021] The surface of the surface film layer 1 of the utility model is treated by electron irradiation strengthening. The surface electron irradiation strengthening treatment technology is a prior art. For example, Chinese invention CN108752792A discloses a method for preparing an electron irradiation surface strengthened scratch-resistant polymer decorative film, which introduces the technical scheme of the surface electron irradiation strengthening treatment technology in detail. Therefore, in this application document, the principle of this technology will not be repeated.

[0022] The thermal bonding adhesive film layer 2 is a hot melt adhesive, and the self-adhesive layer 8 is an acrylic hot melt pressure sensitive self-adhesive.

[0023] The material of the surface film layer 1 is one of polyethylene, polypropylene, polyvinyl chloride or polyurethane, and the woven fiber mesh layer 3 cooperates with the surface film layer 1. More specifically, the cooperation relationship between the woven fiber mesh layer 3 and the surface film layer 1 is as follows:

[0024] 1. The material of the surface film layer 1 is polyethylene, the woven fiber mesh layer 3 is a polyethylene fiber woven mesh, and the surface film layer 1 and the polyethylene fiber woven mesh are thermally bonded by hot melt adhesive;

[0025] 2. The surface film layer 1 is made of polypropylene, the woven fiber mesh layer 3 is a nylon fiber woven mesh or a polyester fiber woven mesh, and the surface film layer 1 and the nylon fiber woven mesh or the polyester fiber woven mesh are thermally bonded by hot melt adhesive;

[0026] 3. The material of the surface film layer 1 is polyvinyl chloride, the woven fiber mesh layer 3 is a nylon fiber woven mesh or a polyester fiber woven mesh, and the surface film layer 1 and the nylon fiber woven mesh or the polyester fiber woven mesh are thermally bonded by hot melt adhesive;

[0027] Fourth, the material of the surface film layer 1 is polyurethane, the woven fiber mesh layer 3 is a nylon fiber woven mesh or a polyester fiber woven mesh, and the surface film layer 1 and the nylon fiber woven mesh or the polyester fiber woven mesh are thermally bonded by hot melt adhesive;

[0028] That is to say, the woven fiber mesh layer 3 and the surface film layer 1 are compounded with the same material.

[0029] The woven fiber mesh layer 3 adopts a staggered woven horizontal and vertical grid, and the woven hole pattern is a quadrilateral; such a design makes the woven fiber mesh layer 3 more resilient and not easy to be punctured, and the area and density of the hole pattern are more convenient to adjust.

[0030] The material of the waterproof cloth layer 5 is waterproof fabric, and the design of the waterproof cloth layer 5 makes the utility model have a waterproof function; the design of the mesh cloth layer 7 makes the utility model more difficult to be punctured.

[0031] The utility model greatly improves the surface wear resistance and scratch resistance of the corresponding elastic wallpaper or wall stickers. It adopts a surface film layer 1 and a woven fiber mesh layer 3 of the same material for thermal bonding. The production process is simple and controllable. The wear-resistant and scratch-resistant antibacterial elastic wallpaper and wall stickers have a wider range of application scenarios and a longer service life. The surface film layer 1 treated by electron irradiation process has greatly improved its antibacterial and stain-resistant properties.
