Description

Technical Field

[0001] This utility model relates to the field of silicone pad technology, and in particular to a flame-retardant insulating silicone pad. Background Technology

[0002] Silicone pads are flexible cushioning materials made of silicone rubber. They have excellent elasticity, temperature resistance, insulation and chemical stability, and are widely used in electronics, machinery, construction, medical and other fields.

[0003] Patent CN215835748U discloses a high-temperature insulating thermally conductive silicone pad. It includes a middle silicone layer and an outer silicone layer. A strip-shaped through groove is formed on one side of the middle silicone layer. A buffer layer is formed on the outer surface of the middle silicone layer. A flame-retardant layer is formed between the buffer layer and the outer silicone layer. An installation groove is formed near the corner of the flame-retardant layer and the outer silicone layer. When using this patent, flame retardancy is achieved through a flame-retardant layer made of flame-retardant ABS material. However, the aforementioned patent still has some shortcomings in practical use. Because the aforementioned patent is a single unit, if one layer is damaged, the entire unit must be replaced, increasing spare parts costs. Furthermore, continued use will indirectly affect the function of other layers.

[0004] Therefore, there is a need for a flame-retardant insulating silicone pad that allows for easy disassembly and replacement of the functional layer. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents in actual use, since the existing patents are integrated, the whole unit must be replaced when a certain layer is damaged, which increases the cost of spare parts, and continued use will indirectly affect the function of other layers, this utility model provides a flame-retardant insulating silicone pad that is easy to disassemble and replace functional layers.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a flame-retardant insulating silicone pad, comprising a buffer silicone pad, thermally conductive silicone, and flame-retardant silicone. The buffer silicone pad is provided with thermally conductive silicone, and the thermally conductive silicone is provided with flame-retardant silicone. It also includes trapezoidal connecting blocks. Multiple trapezoidal connecting blocks are fixedly connected to both the buffer silicone pad and the flame-retardant silicone. Multiple trapezoidal limiting grooves are formed on the thermally conductive silicone, and the trapezoidal connecting blocks are inserted into adjacent trapezoidal limiting grooves.

[0007] Furthermore, it also includes fixing blocks, disc spring plate groups, and ceramic insulating tubes. Multiple sets of fixing blocks are provided on the buffer silicone pad, one set of fixing blocks is provided with disc spring plate groups, and another set of fixing blocks is provided with ceramic insulating tubes.

[0008] Furthermore, it also includes a first polyimide film and a thermally conductive graphite sheet, wherein the first polyimide film is embedded in the thermally conductive silicone, and the thermally conductive graphite sheet is wrapped inside the first polyimide film.

[0009] Furthermore, it also includes a second polyimide film and expanded graphite, with the second polyimide film embedded within the flame-retardant silicone, and the expanded graphite encapsulated within the second polyimide film.

[0010] Furthermore, it also includes ceramic silicone, with ceramic silicone applied to the flame-retardant silicone.

[0011] Furthermore, it also includes a self-healing fluorosilicone resin coating, with the ceramic silicone having a self-healing fluorosilicone resin coating.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. By attaching the thermally conductive silicone to the buffer silicone pad and the flame-retardant silicone to the thermally conductive silicone, the trapezoidal connecting block on the buffer silicone pad and the flame-retardant silicone is inserted into the trapezoidal limiting groove on the thermally conductive silicone, so that it can be quickly aligned and accurately embedded during the assembly process, thereby allowing for the disassembly and replacement of one layer of material.

[0013] 2. By compressing the disc-shaped spring plate assembly with a fixed block to absorb high-frequency vibrations and reduce the impact of resonance on the equipment, the ceramic insulating tube provides insulation to prevent oxidation or short circuits in the equipment.

[0014] 3. The first and second polyimide films provide high temperature resistance and high insulation, and the thermally conductive graphite sheets conduct heat efficiently along the plane, evenly dispersing hot spots and avoiding local heat accumulation. When exposed to fire, the expanded graphite expands to form a heat-insulating carbon layer, blocking the oxygen supply. Attached Figure Description

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] Example 1: A flame-retardant insulating silicone pad, see reference Figures 1-3 and Figure 5 As shown, it includes a buffer silicone pad 1, a thermally conductive silicone pad 4, and a flame-retardant silicone pad 6. The thermally conductive silicone pad 1 is provided with the thermally conductive silicone pad 4, and the flame-retardant silicone pad 6 is provided with the thermally conductive silicone pad 4. It also includes trapezoidal connecting blocks 8. Multiple trapezoidal connecting blocks 8 are fixedly connected to the upper part of the buffer silicone pad 1 and the lower part of the flame-retardant silicone pad 6. Multiple trapezoidal limiting grooves 9 are opened on both the top and bottom parts of the thermally conductive silicone pad 4. The trapezoidal connecting blocks 8 are inserted into the adjacent trapezoidal limiting grooves 9.

[0023] See Figure 1 and Figure 3 As shown, it also includes ceramic silicone 10, and the flame-retardant silicone 6 is provided with ceramic silicone 10.

[0024] See Figures 1-3 As shown, it also includes a self-healing fluorosilicone resin coating 11, and the ceramic silicone 10 is provided with a self-healing fluorosilicone resin coating 11.

[0025] Before using this device, the thermally conductive silicone 4 is attached to the buffer silicone pad 1, and the flame-retardant silicone 6 is attached to the thermally conductive silicone 4. This allows the trapezoidal connecting block 8 on the buffer silicone pad 1 and the flame-retardant silicone 6 to be inserted into the trapezoidal limiting groove 9 on the thermally conductive silicone 4. This enables quick alignment and accurate embedding during assembly, allowing for the removal and replacement of one layer of material. It also ensures that the three layers of silicone are tightly fitted, preventing interlayer displacement, while allowing for slight deformation during thermal expansion. When needed, the buffer silicone pad 1 absorbs mechanical vibration and impact, preventing external stress from being transmitted to the internal structure. The thermally conductive silicone 4 conducts heat from the heat source to the flame-retardant silicone 6, avoiding local overheating. In high-temperature or open-flame environments, the flame-retardant silicone 6 inhibits the spread of flame, thus providing flame retardancy. The ceramic silicone 10 can withstand temperatures up to 1200℃ and is sintered into a ceramic state at high temperatures, isolating flames and heat. When the self-healing fluorosilicone resin coating 11 is scratched, it can automatically cross-link and repair itself, restoring its own properties.

[0026] Example 2: Based on Example 1, refer to Figures 2-4As shown, it also includes a fixing block 2, a disc spring plate group 3 and a ceramic insulating tube 301. Multiple sets of fixing blocks 2 are evenly spaced on the buffer silicone pad 1. Two fixing blocks 2 form a group. A disc spring plate group 3 is arranged between the two fixing blocks 2 in a group. A ceramic insulating tube 301 is arranged between the two fixing blocks 2 in a group. The ceramic insulating tube 301 is located inside the disc spring plate group 3.

[0027] When the silicone pad is vibrated, the deformation of the disc spring assembly 3 by the fixed block 2 absorbs the high-frequency vibration, reducing the impact of resonance on the equipment. At the same time, the ceramic insulating tube 301 provides insulation to prevent the equipment from oxidizing or short-circuiting.

[0028] See Figure 2 , Figure 3 and Figure 5 As shown, it also includes a first polyimide film 5 and a thermally conductive graphite sheet 501. The first polyimide film 5 is embedded in the thermally conductive silicone 4, and the thermally conductive graphite sheet 501 is wrapped inside the first polyimide film 5.

[0029] See Figure 2 , Figure 3 and Figure 5 As shown, it also includes a second polyimide film 7 and expanded graphite 701. The flame-retardant silicone 6 is embedded with the second polyimide film 7, and the second polyimide film 7 is covered with expanded graphite 701.

[0030] When using silicone pads, the first polyimide film 5 and the second polyimide film 7 provide high temperature resistance and high insulation, and the thermally conductive graphite sheet 501 conducts heat efficiently along the plane, evenly dispersing hot spots and avoiding local heat accumulation. When exposed to fire, the expanded graphite 701 expands in volume to form a heat-insulating carbon layer, blocking the oxygen supply, thereby further retardant the flame.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
