Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of double-sided tapes, in particular to a high-temperature cotton paper double-sided tape. Background Art
[0002] A tape is composed of a base material and an adhesive. By bonding, two or more non-connected objects are joined together. A layer of adhesive is coated on its surface. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of adhesives; while nowadays, various polymers are widely used. The adhesive can stick things because bonds are formed between its own molecules and the molecules of the items to be joined, and these bonds can firmly bond the molecules together.
[0003] However, the existing tapes are prone to losing their adhesiveness in high-temperature environments, resulting in poor bonding effects; the base materials of some tapes are not heat-resistant and are prone to deformation or damage in high-temperature environments. Summary of the Invention
[0004] The purpose of the utility model is to provide a high-temperature cotton paper double-sided tape with good high-temperature resistance, which can maintain adhesiveness in high-temperature environments. At the same time, the base material of this tape uses cotton paper, which has good flexibility and strength and is not prone to deformation or damage, so as to solve the above technical problems.
[0005] To achieve the above technical solution, the technical solution of the utility model is as follows: A high-temperature cotton paper double-sided tape includes a cotton paper base layer and high-temperature resistant adhesive layers coated on both sides of the cotton paper base layer. A microfluid heat dissipation layer is provided between the adjacent cotton paper base layer and high-temperature resistant adhesive layers; the microfluid heat dissipation layer includes an evaporation area and a condensation area, and the adjacent evaporation area and condensation area are connected by a ring-shaped wool tube; water is filled in the ring-shaped wool tube.
[0006] Further, the cotton paper base layer is a cotton paper layer with a thickness of 0.1 mm pressed from heat-resistant fiber materials.
[0007] Further, the high-temperature resistant adhesive layer is a high-temperature resistant adhesive layer with a thickness of 1 mm coated on both sides of the cotton paper base layer after being made by mixing and stirring high-temperature resistant resin, adhesive and alumina particles.
[0008] Further, after vaporizing in the evaporation area, it flows to the condensation area for condensation, and the condensed water flows back to the evaporation area through the microstructural capillary action of the ring-shaped wool tube to complete a heat transfer cycle.
[0009] Further, the temperature difference between the evaporation area and the condensation area is at least 0.5 °C.
[0010] Furthermore, the high-temperature cotton paper double-sided tape further includes heat dissipation fins; the heat dissipation fins are arranged on both sides of the high-temperature cotton paper double-sided tape; the heat dissipation fins are in surface contact with the condensation area.
[0011] Furthermore, the high-temperature cotton paper double-sided tape further includes a layer of high-temperature resistant isolation film, and the isolation film is located outside the high-temperature resistant adhesive layer.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] 1) By adopting high-temperature resistant materials and a high-temperature resistant adhesive layer, the utility model can maintain excellent adhesiveness in a high-temperature environment and meet the bonding requirements in a high-temperature environment.
[0014] 2) The cotton paper base layer of the utility model is made of high-temperature resistant fiber materials and has excellent mechanical strength, and can maintain a stable structure in a high-temperature environment. In addition, the setting of a thickness of 0.1 mm can enable the tape to not only exhibit sufficient flexibility, so as to be perfectly adhered to various complex shapes and uneven surfaces, but also endow the tape with sufficient strength, so that it can maintain the integrity of the structure and the stability of the performance under stretching, tearing and other external forces.
[0015] 3) By arranging a microchannel heat dissipation layer between the cotton paper base layer and the high-temperature resistant adhesive layer, that is, as long as the temperature difference between the evaporation area and the condensation area is more than 0.5 °C, a reflux can be formed to conduct the temperature of the evaporation area to the condensation area. Of course, if the temperature difference between the two is larger and the conduction area is larger, the reflux speed is faster, the conduction ability is stronger, and the heat dissipation effect is better. It can effectively improve the heat dissipation effect by 25-35%, and further ensure that the high-temperature resistant adhesive layer can effectively inhibit the molecular chain breakage and performance decline of the adhesive at high temperature, and ensure that the adhesive always maintains good adhesiveness and cohesive strength, thereby laying a solid foundation for the long-term stable bonding performance of the tape in a high-temperature environment.
[0016] 4) The isolation film located outside the high-temperature resistant adhesive layer of the utility model not only effectively protects the high-temperature resistant adhesive layer from being eroded and damaged by external environmental factors, but also significantly improves the wear resistance of the tape, and further extends the service life and application stability of the tape.

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.
[0021] In order to enable those skilled in the art in this technical field to better understand the solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] Please refer to the attached Figures 1 to 2 As shown: A high-temperature cotton paper double-sided tape includes a cotton paper base layer 1 and high-temperature resistant adhesive layers 2 coated on both sides of the cotton paper base layer 1. A microfluidic heat dissipation layer 3 is provided between the adjacent cotton paper base layer 1 and high-temperature resistant adhesive layer 2; the microfluidic heat dissipation layer 3 includes an evaporation area 31 and a condensation area 32, and the adjacent evaporation area 31 and condensation area 32 are connected by an annular woolen tube 33; water is filled in the annular woolen tube 33.
[0023] Based on the above embodiment, the cotton paper base layer 1 is a cotton paper layer with a thickness of 0.1 mm pressed from high-temperature resistant fiber materials. In this embodiment, the cotton paper base layer is made of high-temperature resistant fiber materials, has excellent mechanical strength, and can maintain a stable structure in a high-temperature environment. In addition, the 0.1 mm thickness setting can enable the tape to exhibit sufficient flexibility, so that it can be perfectly attached to various complex shapes and uneven surfaces, and can also endow the tape with sufficient strength, so that it can maintain the integrity of the structure and the stability of the performance under stretching, tearing and other external forces.
[0024] Based on the above embodiment, the high-temperature resistant adhesive layer 2 is a high-temperature resistant adhesive layer 2 with a thickness of 1 mm coated on both sides of the cotton paper base layer 1 after being made by mixing and stirring high-temperature resistant resin, adhesive and alumina particles. Such a setting can ensure a stable adhesive force in a high-temperature environment, and the incorporation of micron-sized alumina particles can enhance the heat conductivity, which is convenient for the microfluidic heat dissipation layer 3 to quickly dissipate it, and improves the service life.
[0025] Based on the above embodiments, after vaporization in the evaporation zone 31, it flows to the condensation zone 32 for condensation. The condensed water flows back to the evaporation zone 31 under the capillary action of the microstructures of the annular woolen tube 33 to complete a heat transfer cycle. The temperature difference between the evaporation zone and the condensation zone is at least 0.5 °C. That is, during operation, as long as the temperature difference between the evaporation zone and the condensation zone is more than 0.5 °C, a reflux can be formed to conduct the temperature of the evaporation zone to the condensation zone. Of course, the greater the temperature difference between the two and the larger the conduction zone, the faster the reflux speed, the stronger the conduction ability, and the better the heat conduction effect, which can effectively improve the heat dissipation effect by 25-35%.
[0026] Based on the above embodiments, the high-temperature cotton paper double-sided tape further includes a heat dissipation fin 4 for communicating with the external environment to dissipate heat in a timely manner. The heat dissipation fin 4 is disposed on both sides of the high-temperature cotton paper double-sided tape. The heat dissipation fin 4 is in surface contact with the condensation zone 32. During use, when the condensation zone 32 contacts the heat dissipation fin 4, the heat is quickly conducted to the heat dissipation fin 4 in a timely manner, and after condensing into water droplets, it flows back under capillary action. The entire process can quickly dissipate the heat inside the high-temperature cotton paper double-sided tape in a timely manner, ensuring that the high-temperature resistant adhesive layer can effectively inhibit the molecular chain breakage and performance decline of the adhesive at high temperatures, and ensuring that the adhesive always maintains good viscosity and cohesive strength, thus laying a solid foundation for the long-term stable bonding performance of the tape in a high-temperature environment.
[0027] Based on the above embodiments, the high-temperature cotton paper double-sided tape further includes a high-temperature resistant isolation film 5, and the isolation film is located outside the high-temperature resistant adhesive layer 2. By adopting the above design, it not only effectively protects the high-temperature resistant adhesive layer from being eroded and damaged by external environmental factors, but also significantly improves the wear resistance of the tape, further extending the service life and application stability of the tape.
[0028] The above are only the preferred embodiments of the present invention and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art, without departing from the scope of the technical solution of the present invention, should be able to make equivalent embodiments of equivalent changes by making some modifications or decorations using the disclosed technical content above. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes, and decorations made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
