It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0021] See also Figures 1 to 4The embodiment of the utility model provides an antistatic PET silicone protective film, comprising a base PET film layer 1, an antistatic layer 2, a functional enhancement layer 3, a silicone coating 4 and an adhesive layer 5 which are sequentially laminated from top to bottom, release holes 6 are symmetrically arranged on both sides of the base PET film layer 1, and an exhaust mechanism is arranged on the adhesive layer 5;

[0022] In this embodiment, the base PET film layer 1, the antistatic layer 2, the functional enhancement layer 3, the silicone coating 4 and the adhesive layer 5 are bonded to each other from top to bottom. When in use, the adhesive layer 5 is used to bond with the protected object. During the bonding process, the exhaust mechanism on the adhesive layer 5 discharges the excess bubbles, thereby reducing the bubbles on the contact surface of the film and the object after the film is bonded. The release hole 6 can be used to facilitate the separation of the film and the protected object.

[0023] The base PET film layer 1 is on the top of the entire protective film. Its main function is to protect the film itself and provide basic physical protection. It also has properties such as wear resistance, scratch resistance and transparency.

[0024] The antistatic layer 2 is located below the base PET film layer 1, and its main function is to eliminate static charge to prevent static electricity from having an adverse effect on the protective film;

[0025] The functional reinforcement layer 3 can absorb ultraviolet rays, thereby preventing ultraviolet rays from damaging the protective film, and as a reinforcement material, it can improve the strength and toughness of the protective film. The functional reinforcement layer 3 has a dense reinforcement network to improve the mechanical properties of the material;

[0026] The silicone coating 4 is located below the functional reinforcement layer 3, and its main function is to increase the adhesion between the protective film and the protected object to ensure that the protective film can remain stable under various environments and usage conditions;

[0027] The adhesive layer 5 is located at the bottom of the entire protective film, and its main function is to enable the protective film to fit tightly onto the surface of the protected object.

[0028] See also Figures 1 to 4 The functional reinforcement layer 3 is evenly distributed with carbon nanotubes, the diameter of which is 50-80nm. The carbon nanotubes can be used as reinforcement materials to improve the strength and toughness of the protective film. Due to their nanoscale diameter of 50-80nm, a denser reinforcement network can be formed in the protective film, thereby improving the mechanical properties of the material. In addition, arranging carbon nanotubes on the protective film can effectively improve the UV resistance of the protective film, making it more durable and reliable during use.

[0029] See also Figures 1 to 4The exhaust mechanism includes a reserved cavity 7 symmetrically opened at the bottom of the adhesive layer 5, an exhaust groove 8 is arranged on the adhesive layer 5 and between the two reserved cavities 7, and a micro-conical hole 9 is opened on one side of the reserved cavity 7 away from the exhaust groove 8. The micro-conical hole 9 is in a closed state when not exhausting;

[0030] In this embodiment, during the process of laminating the present film to the protected object, the laminating is performed slowly from one end thereof. During the laminating process, the exhaust groove 8 on the adhesive layer 5 contacts the protected object, and during the contact process, the air in the exhaust groove 8 is squeezed into the reserved cavity 7, and the air inside the reserved cavity 7 is discharged through the micro-conical hole 9, thereby reducing the bubbles formed between the present film and the protected object. The micro-conical hole 9 is conical, and the air in the reserved cavity 7 can be discharged when squeezed, and the connection between the present film and the protected object is stabilized when squeezed.

[0031] See also Figures 1 to 4 The antistatic layer 2 includes at least one of polystyrene, polypropylene, and polyethylene. Polystyrene is a common plastic material with high insulation performance and is often used in the manufacture of electronic product shells. The use of polystyrene in the antistatic layer can effectively reduce surface resistance, prevent static electricity accumulation, and improve the antistatic performance of the product; polypropylene has excellent wear resistance and impact resistance. The use of polypropylene in the antistatic layer can increase the durability and impact resistance of the product while maintaining a good antistatic effect; polyethylene has the advantages of lightness, easy processing and low cost, and is often used in the manufacture of films and packaging materials. The use of polyethylene in the antistatic layer can achieve good light transmittance and moisture resistance, while maintaining a low surface resistance and effectively preventing static electricity accumulation.

[0032] See also Figures 1 to 4 The adhesive layer 5 also includes an adhesive, which is a pressure-sensitive adhesive. The pressure-sensitive adhesive is an adhesive material with pressure-sensitive properties. It can be pasted and separated by applying slight pressure at room temperature. The pressure-sensitive adhesive has the advantages of easy use, strong adaptability and stable performance.

[0033] In summary, the protective film composed of the base PET film layer 1, the antistatic layer 2, the functional reinforcement layer 3, the silicone coating 4 and the adhesive layer 5 which are bonded to each other from top to bottom, when in use, is bonded to the protected article through the adhesive layer 5. During the bonding process, the excess bubbles are discharged through the exhaust mechanism on the adhesive layer 5, thereby reducing the appearance of bubbles on the contact surface of the film and the article after the film is bonded to the article, thereby ensuring the adhesion between the film and the protected article and preventing it from falling off; and the antistatic layer 2 can eliminate static electricity to prevent static electricity from having an adverse effect on the protective film.
