Description

Technical Field

[0001] The utility model relates to the technical field of gaskets, in particular to an insulating silicone gasket. Background Art

[0002] A silicone gasket is a gasket made of silicone material, usually used for sealing and insulation in industrial and mechanical equipment. Silicone has excellent high-temperature resistance, chemical corrosion resistance and good elasticity. Therefore, silicone gaskets are very common in various applications. Insulating silicone gaskets are usually used in electronic and electrical equipment to prevent the flow of current or short circuits between circuit components.

[0003] However, in the prior art, the silicone gasket uses its own physical properties to resist external pressure. The existing insulating silicone gasket is a single-layer circular sheet structure. Long-term pressure is likely to cause deformation of the entire silicone gasket, resulting in a decrease in the sealing performance, insulation performance and compressive capacity of the silicone gasket, thereby affecting the use effect and service life of the silicone gasket. Content of the Utility Model

[0004] The purpose of the utility model is to provide an insulating silicone gasket.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an insulating silicone gasket, including a first gasket, a second gasket, a first reinforcing plastic sheet and a second reinforcing plastic sheet. The bottom of the first reinforcing plastic sheet is fixedly connected with a porous material layer. The bottom of the porous material layer is fixedly connected with a high molecular flame retardant layer. The bottom of the high molecular flame retardant layer is fixedly connected with a reinforcing fiber layer. The materials of the first gasket and the second gasket are silicone materials. While having good high-temperature resistance and chemical resistance, the silicone material also has good electrical insulation performance, good elasticity and softness. Therefore, it can adapt to the shapes of different surfaces, thereby providing good sealing performance. The silicone gasket uses its own physical properties to resist external pressure, absorbs and disperses energy to a certain extent, and reduces the influence of external shocks and vibrations through its elastic characteristics, thereby absorbing kinetic energy to a certain extent. By setting the porous material layer, the vibration energy is absorbed through the pores, thereby reducing the transmission of vibration and reducing the wear of the overall silicone gasket caused by vibration during use. By setting the high molecular flame retardant layer, the overall silicone gasket is flame-retarded, thereby ensuring the use safety in high-temperature environments. By setting the reinforcing fiber layer, the reinforcing fiber layer is woven from carbon fiber and fibers of some high molecular materials. The high molecular materials are polyester fiber, polypropylene fiber, etc., which have certain energy absorption performance. Carbon fiber has the characteristics of high strength and high modulus, and also has good energy absorption performance, which can effectively absorb impact energy, thereby prolonging the service life of the silicone gasket.

[0006] Preferably, the bottom of the first gasket is fixedly connected to the top of the first reinforced plastic sheet, and the bottom of the second reinforced plastic sheet is fixedly connected to the top of the second gasket. The first and second reinforced plastic sheets are glass fiber reinforced plastics, which have high hardness and strength, and also have good insulation properties.

[0007] Preferably, the bottom of the reinforcing fiber layer is fixedly connected to the top of the second reinforced plastic sheet. The thickness of the reinforcing fiber layer is greater than that of the second reinforced plastic sheet. The reinforcing fiber layer is woven from carbon fiber and fibers of some polymer materials. The polymer materials are polyester fiber, polypropylene fiber, etc., which have good energy absorption performance and can effectively absorb impact energy, thereby prolonging the service life of the silica gel gasket.

[0008] Preferably, multiple groups of geometric protrusions are provided on the top of the first gasket, and multiple groups of anti-slip protrusions are provided on the bottom of the second gasket. By setting the geometric protrusions and anti-slip protrusions, the vibration energy can be better dispersed and absorbed, and it has a good anti-collision and anti-extrusion effect. While ensuring the sealing performance, it can also reduce the wear degree and prolong the service life of the first gasket.

[0009] Preferably, the thickness of the first gasket is greater than that of the second gasket, and the thickness of the porous material layer is greater than that of the reinforcing fiber layer. By setting the porous material layer, the vibration energy is absorbed through the pores, thereby reducing the transmission of vibration and reducing the wear of the overall silica gel gasket caused by vibration during use.

[0010] Preferably, the thickness of the polymer flame retardant layer is less than that of the reinforcing fiber layer and greater than that of the second reinforced plastic sheet. By setting the polymer flame retardant layer, the overall silica gel gasket is flame-retarded, thereby ensuring the use safety in high-temperature environments.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] 1. In the present utility model, by setting the porous material layer, the vibration energy is absorbed through the pores, thereby reducing the transmission of vibration and reducing the wear of the overall silica gel gasket caused by vibration during use.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0020] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0021] Such as Figures 1-4As shown in the figure, the present utility model provides an insulating silicone gasket, which includes a first gasket 1, a second gasket 2, a first reinforced plastic sheet 3 and a second reinforced plastic sheet 7. A porous material layer 4 is fixedly connected to the bottom of the first reinforced plastic sheet 3. A polymer flame retardant layer 5 is fixedly connected to the bottom of the porous material layer 4. A reinforced fiber layer 6 is fixedly connected to the bottom of the polymer flame retardant layer 5. The materials of the first gasket 1 and the second gasket 2 are silicone materials. While the silicone material has good high temperature resistance and chemical resistance, it also has good electrical insulation performance, good elasticity and softness. Therefore, it can adapt to the shapes of different surfaces, thereby providing good sealing performance. The silicone gasket uses its own physical properties to resist external pressure, absorbs and disperses energy to a certain extent, and reduces the impact of external shocks and vibrations through its elastic characteristics, thereby absorbing kinetic energy to a certain extent. By setting the porous material layer 4, the vibration energy is absorbed through the pores, thereby reducing the transmission of vibration and reducing the wear of the overall silicone gasket during use due to vibration. By setting the polymer flame retardant layer 5, the overall silicone gasket is flame-retarded, thus ensuring the use safety in high temperature environments. By setting the reinforced fiber layer 6, the reinforced fiber layer 6 is woven from carbon fiber and some fibers of polymer materials. The polymer materials are polyester fiber, polypropylene fiber, etc., which have certain energy absorption performance. The carbon fiber has the characteristics of high strength and high modulus, and also has good energy absorption performance, which can effectively absorb impact energy, thereby prolonging the service life of the silicone gasket.

The thickness of the reinforced fiber layer 6 is greater than the thickness of the second reinforced plastic sheet 7. The reinforced fiber layer 6 is woven from carbon fiber and some fibers of polymer materials. The polymer materials are polyester fiber, polypropylene fiber, etc., which have good energy absorption performance and can effectively absorb impact energy, thereby prolonging the service life of the silicone gasket.

[0024] As Figures 1-4 shown, multiple groups of geometric protrusions 8 are arranged on the top of the first gasket 1, and multiple groups of anti-slip protrusions 9 are arranged on the bottom of the second gasket 2. By setting the geometric protrusions 8 and the anti-slip protrusions 9, the vibration energy can be better dispersed and absorbed, and it has a good anti-collision and anti-extrusion effect. While ensuring the sealing performance, it can also reduce the wear degree and prolong the service life of the first gasket 1.

[0025] AsFigures 1-4 As shown, the thickness of the first gasket 1 is greater than that of the second gasket 2, and the thickness of the porous material layer 4 is greater than that of the reinforcing fiber layer 6. By providing the porous material layer 4, the vibration energy is absorbed through the pores, thereby reducing the transmission of vibration and minimizing the wear of the overall silicone gasket during use due to the vibration that occurs.

[0026] As Figures 1-4 shown, the thickness of the polymer flame-retardant layer 5 is less than that of the reinforcing fiber layer 6, and the thickness of the polymer flame-retardant layer 5 is greater than that of the second reinforced plastic sheet 7. By providing the polymer flame-retardant layer 5, a flame-retardant effect is achieved on the overall silicone gasket, thereby ensuring the safety of use in a high-temperature environment.

[0027] The usage method and working principle of this device: The materials of the first gasket 1 and the second gasket 2 are silicone materials. While having good high-temperature resistance and chemical resistance, silicone materials also have good electrical insulation properties, good elasticity, and softness. Therefore, they can adapt to the shapes of different surfaces, thereby providing good sealing performance. The silicone gasket utilizes its own physical properties to resist external pressure, absorbs and disperses energy to a certain extent, and reduces the impact of external shocks and vibrations through its elastic characteristics, thereby absorbing kinetic energy to a certain extent. The porous material layer 4 absorbs vibration energy through the pores, thereby reducing the transmission of vibration. The polymer flame-retardant layer 5 has a flame-retardant effect on the overall silicone gasket. The reinforcing fiber layer 6 is woven from carbon fiber and some fibers of polymer materials. The polymer materials are polyester fiber, polypropylene fiber, etc., and have certain energy absorption properties. Carbon fiber has the characteristics of high strength and high modulus, and also has good energy absorption properties, and can effectively absorb impact energy. The first reinforced plastic sheet 3 and the second reinforced plastic sheet 7 are glass fiber-reinforced plastics, which have high hardness and strength, and also have good insulation properties. The geometric protrusions 8 and the anti-slip protrusions 9 can better disperse and absorb vibration energy, and have a good anti-collision and anti-extrusion effect. While ensuring the sealing performance, the wear degree can also be reduced.
