[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0018] Embodiment: Refer to Figs. 1-3 The PET double-layer anti-static silicone protective film comprises a PET substrate layer 8, a first silicone protective layer 7 arranged on one side of the PET substrate layer 8, a second silicone protective layer 9 arranged on the other side of the PET substrate layer 8, a waterproof layer 6 arranged on one side of the first silicone protective layer 7, a fireproof layer 5 arranged on one side of the waterproof layer 6, an anti-static layer 4 arranged on one side of the fireproof layer 5, an oil-resistant layer 3 arranged on one side of the anti-static layer 4, a wear-resistant layer 2 arranged on one side of the oil-resistant layer 3, and a release film 1 arranged on one side of the wear-resistant layer 2.

[0019] Specifically, the waterproof layer 6 is made of a waterproof coating. The waterproof layer 6 is made of a waterproof coating, and the molecular structure of the silicone coating contains a large number of hydrophobic groups, such as long-chain alkyl groups, which can further enhance the waterproof performance of the protective film. When water contacts the silicone protective film coated with the waterproof layer, water droplets will form on the surface and roll off, rather than penetrating in.

[0020] Specifically, the fireproof layer 5 is made of fireproof paint, and the thickness of the fireproof paint is 0.5 mm. The fireproof layer 5 is made of fireproof paint, and the thickness of the fireproof paint is 0.5 mm. The fireproof coating is a material coated on the surface of the silicone protective film. When encountering fire, the coating will expand, carbonize, and other reactions, forming a protective layer that insulates heat and oxygen, thereby achieving the purpose of fireproofing.

[0021] Specifically, the anti-static layer 4 is made of an anti-static coating, and the anti-static coating is a metal oxide that can effectively reduce surface resistance and prevent the generation and accumulation of static electricity. This anti-static coating usually has good conductivity and stability, and can maintain anti-static performance for a long time.

[0022] Specifically, the oil-resistant layer 3 is made of an oil-resistant coating, and the thickness of the oil-resistant coating is 0.2 mm. The oil-resistant layer 3 is made of an oil-resistant coating, and the thickness of the oil-resistant coating is 0.2 mm. Some fluorocarbon coatings have excellent oil resistance and chemical corrosion resistance. The fluorine atoms in the fluorocarbon coating have very low polarizability, making the surface energy of the coating very low, so oil droplets are difficult to spread and penetrate on its surface, thereby making the PET substrate 8 have good oil resistance.

[0023] Specifically, the material of the wear-resistant layer 2 is a polyimide film. Through the setting of the wear-resistant layer 2, the material of the wear-resistant layer 2 is a polyimide film. The main chain structure of polyimide is mainly composed of aromatic rings (benzene rings and imide rings). There are few single bonds in the molecular chain that can rotate freely, and the conformation structure hardly changes. Therefore, it has a high glass transition point and melting point, which enables it to maintain good mechanical properties in a high-temperature environment, thereby better maintaining the integrity of the surface during friction and reducing wear. The polyimide film has high hardness, strength and rigidity, and can withstand a large load without being easily deformed and damaged. When in contact with other objects during friction, its surface can effectively resist the action of external force, reducing the degree of wear, thereby enabling the PET base material 8 to have good wear resistance.
