Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tapes, and more specifically, to a high-viscosity and heat-resistant double-sided tape. Background Technique
[0002] With the development of electronic products, in order to facilitate the installation of components, most of them are pasted with double-sided tape. However, when electronic components work for a long time, they often emit heat to the outside. However, since the glue used in the double-sided tape usually does not have sufficient high-temperature resistance, when the electronic components emit heat to the outside for a long time, these heats will cause the glue on the double-sided tape to soften or even melt, resulting in a decrease in adhesion, and further affecting the fixing effect of the electronic components. Once the double-sided tape loses its adhesion, the electronic components will loosen or fall off. Therefore, we propose a high-viscosity and heat-resistant double-sided tape to solve the above problems. Content of the Utility Model
[0003] The main purpose of the utility model is to provide a high-viscosity and heat-resistant double-sided tape, which solves the problem that when electronic components work for a long time, they often emit heat to the outside. However, since the glue used in the double-sided tape usually does not have sufficient high-temperature resistance, when the electronic components emit heat to the outside for a long time, these heats will cause the glue on the double-sided tape to soften or even melt, resulting in a decrease in adhesion, and further affecting the fixing effect of the electronic components. Once the double-sided tape loses its adhesion, the electronic components will loosen or fall off.
[0004] To achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A high-viscosity and heat-resistant double-sided tape, including a tape body. Protective layers are respectively adhered and installed on the upper and lower sides of the tape body. The tape body includes a support base layer. Reinforcement layers are respectively installed at the upper and lower ends of the support base layer. Heat-conducting layers are respectively installed on the sides of the reinforcement layers away from each other. Connection layers are respectively installed at the ends of the heat-conducting layers away from each other. Adhesive layers are respectively installed on the sides of the connection layers away from each other. The adhesive layers are connected to the protective layers.
[0006] Preferably, a number of transfer blocks are respectively installed on the sides of the heat-conducting layers away from each other. The transfer blocks are respectively installed through the inside of the connection layer. The transfer blocks are respectively in contact with the adhesive layers.
[0007] Preferably, the protective layer includes a peel-off layer. The peel-off layers are respectively adhered and installed on the surfaces of the adhesive layers.
[0008] Preferably, protective layers are respectively installed on the sides of the peel-off layers away from the adhesive layers.
[0009] Preferably, the adhesive layer is made of a silicone-based glue material, the reinforcing layer is made of polylactic acid fiber material, the heat-conducting layer and the transfer block are made of heat-conducting ceramic powder material, and the protective layer is made of polyvinyl chloride material.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] (1) In the utility model, the adhesive layer is made of a silicone-based glue, so that due to the high-temperature resistance and high viscosity of the silicone-based glue, the adhesive layer can still maintain stable performance in a high-temperature environment, and is not likely to decompose or fail. Then, the heat-conducting layer and the transfer block are both made of heat-conducting ceramic powder, which can not only transfer and dissipate the overall temperature, but also enhance the overall high-temperature resistance performance to better protect the whole.
[0012] (2) In the utility model, the protective layer is made of polyvinyl chloride material. Due to its excellent weather resistance and corrosion resistance, and at the same time having relatively high mechanical strength, it can form an additional protective layer to prevent the double-sided tape from being damaged by the external environment.

[0018] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. 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.
[0019] As Figures 1 to 4 shown, an embodiment of the present utility model provides a high-viscosity temperature-resistant double-sided tape, which includes a tape body 1. Protective layers 2 are respectively adhered and installed on the upper and lower sides of the tape body 1. The tape body 1 includes a support base layer 101. Reinforcement layers 102 are respectively installed at the upper and lower ends of the support base layer 101. Heat-conducting layers 103 are respectively installed on the sides of the reinforcement layers 102 away from each other. Connection layers 104 are respectively installed at the ends of the heat-conducting layers 103 away from each other. Adhesive layers 106 are respectively installed on the sides of the connection layers 104 away from each other. The adhesive layers 106 are connected to the protective layers 2.
[0020] As Figure 4 shown, in another embodiment of the present utility model, a number of transfer blocks 105 are respectively installed on the sides of the heat-conducting layers 103 away from each other. The transfer blocks 105 are respectively installed through the interiors of the connection layers 104. The transfer blocks 105 are respectively in contact with the adhesive layers 106. The protective layer 2 includes a peel-off layer 201. The peel-off layers 201 are respectively adhered and installed on the surfaces of the adhesive layers 106. Protective layers 202 are respectively installed on the sides of the peel-off layers 201 away from the adhesive layers 106. The adhesive layer 106 is made of a silicone-based glue material. The reinforcement layer 102 is made of a polylactic acid fiber material. The heat-conducting layer 103 and the transfer blocks 105 are made of a heat-conducting ceramic powder material. The protective layer 202 is made of a polyvinyl chloride material.
[0021] The adhesive layer 106 is made of a silicone-based glue. Due to its excellent high-temperature resistance performance, the adhesive layer 106 can maintain a stable adhesive force under high-temperature conditions, ensuring that the double-sided tape can still firmly adhere to electronic components or other objects that need to be adhered under various extreme working temperatures. Then, the silicone-based glue has a high viscosity and can provide a strong adhesive force. This high viscosity enables the double-sided tape to closely adhere to the surface of the object during the pasting process, forming a stable connection. Even when subjected to external forces, it can still maintain a good adhesive effect and is not easy to fall off. Then, the adhesive effect of the silicone-based glue is not only strong but also stable. It can maintain a stable bonding state under various environmental conditions, such as humidity and temperature changes, and is not easily affected by external factors. This enables the double-sided tape to exert an excellent adhesive effect in various complex application scenarios;
[0022] The reinforcing layer 102 is made of polylactic acid fibers. Due to the high mechanical properties of polylactic acid fibers, including high breaking strength and good extensibility, these characteristics enable the polylactic acid fiber reinforcing layer to effectively enhance the overall structural strength of the double-sided tape, making it more durable and less prone to breakage.
[0023] The heat-conducting layer 103 and the transfer block 105 are made of heat-conducting ceramic powder. Due to its excellent heat-conducting performance, it can quickly conduct heat. After installing the heat-conducting layer inside the double-sided tape, it can effectively conduct heat from the heat source device to the heat sink, thereby improving the heat dissipation efficiency, reducing the working temperature of electronic components, enhancing the stability and lifespan of the device, and at the same time, it can also transfer the heat inside the tape body 1 to reduce the heat of the double-sided tape.
[0024] The protective layer 202 is made of polyvinyl chloride. Due to its good weather resistance and corrosion resistance, it also has relatively high mechanical strength. It can provide an additional protective layer to prevent the double-sided tape from being damaged by the external environment.
[0025] The working principle of this high-viscosity and temperature-resistant double-sided tape:
[0026] During use, first, the user removes the release layer 201 and the protective layer 102, and then the user can respectively adhere to the objects through the adhesive layers 106 at the upper and lower ends to complete the installation work of the objects.
[0027] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, based on the above description, other different forms of changes or modifications can be made. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
