[0025] Referring to Figures 1-4 , the present application provides a technical solution: a flame-retardant high-temperature-resistant electronic adhesive tape, comprising a base layer 1, and a base paper 6 glued to the lower surface of the base layer 1.
[0026] The specific settings and effects of the whole will be described below.
[0027] In this embodiment: the upper surface of the base layer 1 is glued with a flame-retardant layer 2, which is a polyimide layer. The polyimide layer structure has a very stable aromatic heterocycle, which makes it have excellent flame-retardant properties. As a flame-retardant layer 2, it improves the flame-retardant properties of the electronic adhesive tape to some extent, and can maintain good stability at high temperatures and is not easy to burn. In addition, the polyimide layer has good insulating properties, which can further improve the insulating properties of the electronic adhesive tape during use.
[0028] The upper surface of the flame-retardant layer 2 is glued with a high-temperature-resistant layer 3, which is a glass fiber cloth layer. The high-temperature-resistant layer 3 made of glass fiber cloth layer has good high-temperature-resistant performance. Glass fiber can be used for a long time at high temperature and has good chemical corrosion resistance, thereby improving the high-temperature-resistant properties of the electronic adhesive tape during use. The surface of the base layer 1 is provided with two tear seams 7. After tearing off the base paper 6 and pasting the product with the electronic adhesive tape, the two narrow base layer 1 can be torn off at the position of the tear seam 7. At this time, the flame-retardant layer 2 and the high-temperature-resistant layer 3 can be pressed and folded, which can realize the shielding and covering of the side position of the base layer 1, thereby further improving the high-temperature-resistant and flame-retardant properties of the electronic adhesive tape during use.
[0029] Specifically, the upper surface of the high-temperature resistant layer 3 is coated with a coating layer 4, which is a magnesium hydroxide coating layer. When heated, the magnesium hydroxide coating layer 4 absorbs a large amount of heat and releases water, which cools and dilutes the combustible gas. The decomposed magnesium oxide forms a heat-insulating layer, preventing heat transfer and flame spread, and further improving the flame-retardant and high-temperature resistant effect of the electronic tape during use.
[0030] The surface of the high-temperature resistant layer 3 is provided with a plurality of circular holes 5. The circular holes 5 on the surface of the high-temperature resistant layer 3 not only increase the roughness of the outer surface of the high-temperature resistant layer 3, but also improve the anti-skid effect of the electronic tape during use, and avoid the phenomenon that the electronic tape is not convenient to dissipate heat due to the thick and full coverage. The anti-puncture layer 8 is embedded in the inside of the flame-retardant layer 2, which is a nylon woven layer. The nylon woven layer has good anti-puncture and use strength, and embedding it in the inside of the flame-retardant layer 2 can effectively avoid the phenomenon that the flame-retardant effect of the flame-retardant layer 2 will be reduced after being punctured, thereby further ensuring the normal use of the electronic tape.
[0031] Working principle: The polyimide layer contains highly stable aromatic heterocyclic rings, giving it excellent flame-retardant properties. Used as flame-retardant layer 2, it improves the flame-retardant performance of the electronic tape during use. It maintains good stability even at high temperatures, making it difficult to burn. Furthermore, the polyimide layer has good insulation properties, further enhancing the insulation performance of the electronic tape. The high-temperature resistant layer 3, made of fiberglass cloth, has excellent high-temperature resistance. Fiberglass can be used for extended periods at high temperatures and has good chemical corrosion resistance, thus improving the high-temperature resistance of the electronic tape. After tearing off the backing paper 6 and attaching the product with the electronic tape, two narrower base layers 1 can be torn off through the tear seam 7. At this point, the flame-retardant layer 2 and the high-temperature resistant layer 3 can be folded, achieving the covering and shielding of the sides of the base layer 1, further improving the high-temperature flame-retardant performance of the electronic tape. The coating layer 4, made of magnesium hydroxide, is heated... When magnesium hydroxide decomposes, it absorbs a large amount of heat and releases moisture, which cools and dilutes flammable gases. The decomposed magnesium oxide forms a heat insulation layer, preventing heat transfer and flame spread, further improving the flame retardant and high-temperature resistance of the electronic tape. By setting circular holes 5 on the surface of the high-temperature resistant layer 3, not only is the roughness of the outer surface of the high-temperature resistant layer 3 increased, improving the anti-slip effect during the use of the electronic tape, but it also avoids the phenomenon that the electronic tape is inconvenient to dissipate heat due to its thick and comprehensive coverage. The nylon braided layer has good puncture resistance and strength. Embedded inside the flame retardant layer 2, it can effectively prevent the flame retardant effect from being reduced after the flame retardant layer 2 is punctured, thereby further ensuring the normal use of the electronic tape. By setting the above structure, the flame retardant and high-temperature resistance of the electronic tape is improved, which can effectively reduce the possibility of fire. Even if it encounters a fire source in an accident, it can slow down or prevent the spread of fire, buy time for fire extinguishing measures, and improve the performance of the electronic tape to a certain extent.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
