Description

Technical Field

[0001] The utility model relates to the technical field of silica gel protective films, and particularly relates to a high-temperature resistant and wear-resistant silica gel protective film. Background Art

[0002] A protective film is a thin film used to protect the surface of items that are vulnerable to damage. Its purpose is to prevent the protected items from being damaged or contaminated during transportation, installation, processing, storage, and use. It will stick to the surface of the protected item until it is torn off and discarded when the item reaches the hands of consumers or users.

[0003] The silica gel protective film is made of a plastic film, an aluminum-plastic composite material, etc. as the base material, with a low-viscosity pressure-sensitive adhesive coated on one side. After being made into a coil, it is cut into pieces. It is usually used to protect devices in the fields of electronic equipment, optics, automobiles, etc.

[0004] Considering that the existing silica gel protective films usually have high-temperature resistance and wear resistance, when the protected device is used for a long time, heat will be generated, causing the protective film to be in a high-temperature environment for a long time. However, due to the poor heat dissipation effect of the protective film, its high-temperature resistance performance will decrease, resulting in a reduction in the use effect and service life of the silica gel protective film. Moreover, the existing silica gel protective film can hardly provide a good buffering effect on the device only through the flexibility of its own material. When the device collides or falls, the wear of the silica gel protective film is relatively serious. Therefore, it is necessary to design a high-temperature resistant and wear-resistant silica gel protective film, which can not only protect the device but also have good high-temperature resistance and wear resistance, thereby improving the service life and protection effect of the silica gel protective film. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a high-temperature resistant and wear-resistant silica gel protective film.

[0006] To achieve this purpose, the utility model adopts the following technical solutions:

The heat dissipation layer includes a trapezoidal cylinder and a fixing block. Air holes are formed in the outer wall of the trapezoidal cylinder, and a heat dissipation air duct is formed in the inner wall of the fixing block.

[0008] Further, the buffer layer includes honeycomb-shaped blocks and spherical protrusions. The bottom of the honeycomb-shaped blocks is fixedly connected to the top of the base layer.

[0015] Advantages of the present utility model: For this high-temperature resistant and wear-resistant silica gel protective film, by providing a heat dissipation layer and a heat-conducting layer, the heat generated during the operation of the device is conducted to the heat dissipation layer through the heat-conducting layer. Subsequently, through the multiple air holes opened on the multiple trapezoidal cylinders provided in the heat dissipation layer, the hot air in the multiple trapezoidal cylinders is transferred to each other for heat dissipation.

[0024] Referring to Figures 1 to 4 A high-temperature resistant and wear-resistant silicone protective film shown, including a base layer 1, the base layer 1 provides basic physical properties and mechanical strength for the silicone protective film, the bottom of the base layer 1 is fixedly connected with a high-temperature resistant layer 2, the material of the high-temperature resistant layer 2 is made of polyimide, polyimide has extremely high high-temperature resistance, can maintain good stability and mechanical properties in high-temperature environments, and is not prone to problems such as deformation and softening. Through the high-temperature resistant layer 2, it plays a high-temperature protection role for the base layer 1, avoiding the base layer 1 from being damaged by excessive heat and causing adhesion. The bottom of the high-temperature resistant layer 2 is fixedly connected with a heat dissipation layer 3, through the heat dissipation layer 3, it plays a heat dissipation role for the silicone protective film, thereby further improving the high-temperature resistance of the silicone protective film. The bottom of the heat dissipation layer 3 is fixedly connected with a heat conduction layer 4, the material of the heat conduction layer 4 is made of silicon carbide, silicon carbide has a relatively high thermal conductivity and high-temperature resistance, and can still maintain good thermal conductivity in high-temperature environments. Through the heat conduction layer 4, the heat generated on the protected device is conducted to the silicone protective film, thereby being able to play a heat dissipation effect on the protected device, and at the same time facilitating the rapid discharge of heat. The bottom of the heat conduction layer 4 is fixedly connected with a bottom layer 5, the material of the bottom layer 5 is made of silicone, silicone has good adhesiveness, flexibility and high-temperature resistance, can maintain stable adhesion in different environments, and is not prone to residual glue when peeled off.

[0025] A buffer layer 6 is fixedly connected to the top of the base layer 1. Through the buffer layer 6, when the protected device is subjected to external collisions such as impacts, the silica gel protective film can buffer the device, and at the same time reduce the wear degree generated when the silica gel protective film is impacted. An antistatic layer 8 is fixedly connected to the top of the buffer layer 6. The antistatic layer 8 is made of conductive fibers, and the conductive fibers include carbon fibers, metal fibers, etc., which can form a three-dimensional conductive network in the silica gel protective film to improve the conductivity and guide static electricity to avoid the impact of static electricity on the device. A wear-resistant layer 7 is fixedly connected to the top of the antistatic layer 8. The wear-resistant layer 7 is made of polyurethane. Polyurethane has good wear resistance, impact resistance and shock absorption, high strength, and at the same time has a certain flexibility, which can improve the wear resistance of the silica gel protective film. The heat dissipation layer 3 includes trapezoidal cylinders 11 and fixing blocks 12. Air holes 13 are formed in the outer wall of the trapezoidal cylinder 11. Both the trapezoidal cylinder 11 and the air holes 13 are provided in multiple groups, and the directions of adjacent two groups of trapezoidal cylinders 11 are opposite.

The outer wall of the fixing block 12 is fixedly connected to the inner wall of the trapezoidal cylinder 11. The inner wall of the heat dissipation air channel 14 is streamlined. Through the streamlined heat dissipation air channel, the flow rate of air in the heat dissipation air channel is increased, and through the exchange rate of external air and the air inside the trapezoidal cylinder 11, the heat dissipation effect and high-temperature resistant performance of the silica gel protective film are further improved.

[0028] The high-temperature and wear-resistant silicone protective film is provided with a heat dissipation layer and a heat conduction layer. The heat generated during the operation of the device is conducted to the heat dissipation layer through the heat conduction layer, and then through multiple air holes opened on multiple trapezoidal cylinders arranged in the heat dissipation layer, the hot air in the multiple trapezoidal cylinders is transferred to each other for heat dissipation. At the same time, due to the design of the streamlined heat dissipation air channels inside the fixing blocks, the air flow rate and exchange rate inside the heat dissipation air channels can be accelerated, further improving the heat dissipation effect of the silicone protective film. And through the honeycomb-shaped blocks arranged in the buffer layer, since the honeycomb-shaped blocks are hexagonal in structure, they have high strength and stability and can provide a large buffer space. At the same time, by arranging multiple spherical protrusions, the contact area between the buffer layer and the anti-static layer can be increased, local pressure can be reduced, and the buffer performance can be improved, so that the high-temperature resistance, wear resistance and protection performance of the silicone protective film are improved.
