[0030] The explosion-proof layer 140 is made of high-strength and high-transparency PET polyester material, which is used to sandwich the metal layer in the middle to prevent metal oxidation and prolong the service life of the metal film. The explosion-proof layer 140 has high toughness, and the glass can be firmly adhered by the film after breaking and will not splash and injure people. Moreover, the explosion-proof layer 140 has strong impact resistance.

[0031] The base layer material of the pressure-resistant layer 150 is a transparent EVA safety base layer, and the wear-resistant layer 110, the heat-insulating layer 120, the light-reflecting layer 130, the explosion-proof layer 140, the pressure-resistant layer 150, and the protective layer 160 are composed of a high-transparency acrylate adhesive with good weather resistance.

[0032] The protective layer 160 is made of an epoxy resin fiber material, and the strength of the black film body 100 is increased through the protective layer 160 made of the epoxy resin fiber material; the protective layer 160 is provided with a plurality of air vent grooves one 161 for discharging air bubbles in the black film body 100, and the plurality of air vent grooves one 161 are linearly arranged in the protective layer 160; the protective layer 160 is provided with a plurality of air vent grooves two 162 for discharging air bubbles in the black film body 100, and the plurality of air vent grooves two 162 are arranged in a cross manner with the plurality of air vent grooves one 161; so that the air bubbles on the adhesive surface can be easily discharged from the side of the black film body 100 along the air vent grooves one 161 and the air vent grooves two 162 when the film is pasted, and the adhesive surface is flat, and the thickness of each film layer is set to ensure that the black film body 100 is easily pasted on the surface of the vehicle body and protects the vehicle body.

[0033] Based on the above content and the drawings, those skilled in the art can understand and implement the present application. In addition, any non-creative modification of the present application made by those skilled in the art without creative labor still falls within the protection scope of the present application.
