Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a heat-bent silicone protective film. Background Art

[0002] The heat-bent silicone protective film is a material used to protect the surface of electronic products, and has the characteristics of high temperature resistance, chemical corrosion resistance, good flexibility, etc. It can be bent at high temperatures and is suitable for products with various curved surface designs, such as mobile phones, tablet computers, car dashboards, etc. The heat-bent silicone protective film can effectively prevent surface scratches, dirt and chemical corrosion, protect the product appearance and extend the service life. At the same time, it also has a certain waterproof and dustproof function, making the product more durable and easy to clean. Currently, during the use of the heat-bent silicone protective film, the fitting degree is somewhat lacking. When encountering products with a large curvature, the fitting degree is prone to occur with white edges or lifting. Being in this state for a long time will further cause the heat-bent silicone protective film to fall off from the product surface. At the same time, the surface protection of the heat-bent silicone protective film is particularly important. When the surface of the heat-bent silicone protective film is rubbed by particles, and water stains appear at the worn position of the heat-bent silicone protective film surface, it is easy to cause erosion, thereby reducing the durability and protective effect of the heat-bent silicone protective film, and also affecting the use of the heat-bent silicone protective film.

[0003] Therefore, it is necessary to develop a heat-bent silicone protective film. Content of the Utility Model

[0004] The purpose of the utility model is to provide a heat-bent silicone protective film. By providing a carbon fiber soft border and a surface protection mechanism, the edge of the silicone protective film is correspondingly provided with a carbon fiber soft border. Since the carbon fiber soft border is a lightweight, high-strength, wear-resistant material, and has good flexibility and tensile resistance, it can effectively protect the product surface from damage, and at the same time perfectly fits products with curved edges, and tries to avoid the situation of white edges or lifting in the later stage due to the unreliable fitting degree of the heat-bent silicone protective film. By adopting a multi-layer protective film layer for the surface protection mechanism and coating it on the surface of the silicone protective film in sequence, on the one hand, the overall surface strength and toughness of the heat-bent silicone protective film can be increased to prevent deformation and damage caused by friction or collision, and on the other hand, the overall surface of the heat-bent silicone protective film can be provided with antibacterial and anti-corrosion effects, and try to avoid the situation of bacteria corrosion caused by the influence of the external environment on the heat-bent silicone protective film, effectively improving the durability and protection of the heat-bent silicone protective film, and also effectively improving the use effect of the heat-bent silicone protective film, so as to solve the problems of low durability and poor bending fitting of the heat-bent silicone protective film mentioned in the above background art.

[0005] To achieve the above object, the present utility model provides the following technical solutions: A thermoformed silicone protective film, including a silicone protective film, on both outer walls of the silicone protective film, carbon fiber flexible frames are installed.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides the following technical solutions: A heat-bent silicone protective film. Please refer to Figures 1-4 ., which includes a silicone protective film 1. Carbon fiber flexible frames 2 are installed on both outer walls of the silicone protective film 1. The silicone protective film 1 includes a heat-bent protective film layer 101. A silicone layer 102 is arranged on the upper surface of the heat-bent protective film layer 101. A bottom support layer 104 is arranged at the bottom of the heat-bent protective film layer 101. The bottom support layer 104 and the heat-bent protective film layer 101 are fixedly connected through an adhesive layer 103 on the opposite side. The silicone protective film 1 is combined by the heat-bent protective film layer 101, the silicone layer 102 and the bottom support layer 104, and then the bottom support layer 104 and the heat-bent protective film layer 101 are adhered by the adhesive layer 103 to form an overall heat-bent silicone protective film. The silicone layer 102 has the characteristics of softness and high temperature resistance, and can be effectively bent at high temperatures to adapt to the surfaces of products with various curved surface designs. The bottom support layer 104 can be used to enhance the strength and stability of the overall structure;

[0021] The carbon fiber soft border 2 includes a carbon fiber wrapping layer 201. A cavity 202 is formed at the inner center position of the carbon fiber wrapping layer 201. A silica gel filler 203 is arranged inside the cavity 202. A sticking piece 204 is arranged on the lower surface of the carbon fiber wrapping layer 201. The edge of the silica gel protective film 1 is correspondingly provided with the carbon fiber soft border 2. Since the carbon fiber soft border 2 is a lightweight, high-strength and wear-resistant material, and has good flexibility and tensile resistance, it can effectively protect the surface of the product from damage. At the same time, it perfectly fits the product with a curved edge, and tries to avoid the occurrence of white edges or lifting at the later stage due to the unreliable fitting degree of the heat-bent silica gel protective film. By filling the cavity 202 inside the carbon fiber wrapping layer 201 of the carbon fiber soft border 2 with the silica gel filler 203, the used silica gel filler 203 has the same material as the silica gel layer 102, and both have the characteristics of being effectively bent at high temperature and adapting to the surfaces of products with various curved surface designs;

[0022] A surface protection mechanism 3 is arranged on the upper surface of the silica gel layer 102. The surface protection mechanism 3 includes a carbon fiber composite film layer 301. From the outside to the inside, the carbon fiber composite film layer 301 is successively provided with a polysiloxane resin film layer 302, a nano-zinc oxide film layer 303 and a polyurethane waterproof film layer 304. The surface protection mechanism 3 adopts multiple protective film layers and is successively coated on the surface of the silica gel layer 102 on the silica gel protective film 1. By virtue of the carbon fiber composite film layer 301 on the surface protection mechanism 3 having functions such as high temperature resistance, abrasion resistance and corrosion resistance, it prevents the overall surface of the heat-bent silica gel protective film from being easily damaged by high temperature, friction and corrosion. By virtue of the polysiloxane resin film layer 302 having the function of good high hardness, it can enhance the hardness of the overall surface of the heat-bent silica gel protective film. By virtue of the nano-zinc oxide film layer 303 having the functions of antibacterial and bacteriostatic, odor removal and mildew prevention and antioxidant, it can carry out antibacterial and bacteriostatic and antioxidant treatment on the overall surface of the heat-bent silica gel protective film, and prevent the overall surface of the heat-bent silica gel protective film from being corroded and oxidized by water stains and water vapor. By virtue of the polyurethane waterproof film layer 304 having characteristics such as high strength, large elongation rate and good water resistance, it can carry out waterproof treatment on the overall surface of the heat-bent silica gel protective film.

[0023] Working principle: When using the present utility model, the silicone protective film 1 is composed of a heat-bent protective film layer 101, a silicone layer 102 and a bottom support layer 104. Then, an adhesive layer 103 is used to bond the bottom support layer 104 and the heat-bent protective film layer 101 to form an integral heat-bent silicone protective film. The silicone layer 102 has the characteristics of softness and high temperature resistance, and can be effectively bent at high temperatures to adapt to the surfaces of products with various curved designs. The bottom support layer 104 can be used to enhance the strength and stability of the overall structure. By correspondingly arranging a carbon fiber soft border 2 at the edge of the silicone protective film 1, since the carbon fiber soft border 2 is a lightweight, high-strength, wear-resistant material with good flexibility and tensile resistance, it can effectively protect the product surface from damage, and at the same time perfectly fits the product with a curved edge, and tries to avoid the occurrence of white edges or lifting at the later stage due to the unreliable fitting degree of the heat-bent silicone protective film. By filling the internal cavity 202 of the carbon fiber wrapping layer 201 on the carbon fiber soft border 2 with a silicone filling material 203, the silicone filling material 203 used has the same material as the silicone layer 102, and both can effectively bend at high temperatures and adapt to the surfaces of products with various curved designs. By using the surface protection mechanism 3 with multiple protective film layers and successively coating the surface of the silicone layer 102 on the silicone protective film 1, the carbon fiber composite film layer 301 on the surface protection mechanism 3 has functions such as high temperature resistance, abrasion resistance and corrosion resistance, preventing the overall surface of the heat-bent silicone protective film from being easily damaged by high temperature, friction and corrosion. The polysiloxane resin film layer 302 has the function of good high hardness, which can enhance the hardness of the overall surface of the heat-bent silicone protective film. The nano-zinc oxide film layer 303 has the functions of antibacterial and bacteriostatic, odor removal and mildew prevention, and antioxidant, which can carry out antibacterial and bacteriostatic and antioxidant treatments on the overall surface of the heat-bent silicone protective film, preventing the overall surface of the heat-bent silicone protective film from being corroded and oxidized by water stains and water vapor. The polyurethane waterproof film layer 304 has characteristics such as high strength, large elongation rate and good water resistance, and can carry out waterproof treatment on the overall surface of the heat-bent silicone protective film. By carrying out protective treatment on the overall surface of the heat-bent silicone protective film, on the one hand, the strength and toughness of the overall surface of the heat-bent silicone protective film are increased, preventing deformation and damage caused by friction or collision. On the other hand, antibacterial and anti-corrosion effects are achieved on the overall surface of the heat-bent silicone protective film, and the occurrence of bacterial corrosion of the heat-bent silicone protective film under the influence of the external environment is avoided as much as possible. The durability and protection of the heat-bent silicone protective film are effectively improved, and the use effect of the heat-bent silicone protective film is also effectively improved.
