[0001] The utility model relates to the technical field of pressure-sensitive adhesives, and more specifically to a high-thermal-conductivity flame-retardant acrylic pressure-sensitive adhesive. Background Art

[0002] Pressure-sensitive adhesive, also known as self-adhesive adhesive, is an adhesive that is usually coated on a film layer and used in people's production and life in the form of an adhesive tape. For example, publication number CN218989160U discloses a high thermal conductivity flame-retardant acrylic pressure-sensitive adhesive, including an aluminum foil surface layer, a first flame-retardant layer, a second flame-retardant layer and an adhesive layer. The bottom of the aluminum foil surface layer is connected to an aluminum foil vertical sheet, the lower end of the aluminum foil surface layer is provided with a first flame-retardant layer, the lower end of the first flame-retardant layer is provided with an adhesive layer, and a second flame-retardant layer is provided between the adhesive layer and the first flame-retardant layer. When the current thermal conductive pressure-sensitive tape is used for heat conduction, the temperature of the tape itself will also increase accordingly. If the tape body is in a high temperature state for a long time, the pressure-sensitive adhesive is prone to failure, affecting the stability of the bonding. Therefore, it is urgent to design a high thermal conductivity flame-retardant acrylic pressure-sensitive adhesive. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a highly thermally conductive flame-retardant acrylic pressure-sensitive adhesive to solve the problem in the above-mentioned background technology that when the existing thermally conductive pressure-sensitive tape is used for heat conduction, the temperature of the tape itself will also increase accordingly. If the tape body is in a high temperature state for a long time, the pressure-sensitive adhesive will easily fail, affecting the stability of the bonding.

[0004] The utility model provides the following technical scheme: a highly thermally conductive flame-retardant acrylic pressure-sensitive adhesive, comprising a device body, the device body comprising a pressure-sensitive adhesive layer, a flame-retardant layer is arranged on the top of the pressure-sensitive adhesive layer, a first aluminum foil surface layer is arranged on the top of the flame-retardant layer, a heat dissipation structure is arranged on the top of the first aluminum foil surface layer, the heat dissipation structure comprises heat dissipation through holes, the heat dissipation through holes are evenly and equidistantly penetrated and opened on the top of the first aluminum foil surface layer, heat dissipation grooves are evenly arranged on the top of the first aluminum foil surface layer, the heat dissipation grooves and the heat dissipation through holes are arranged in parallel on the top of the first aluminum foil surface layer, a sealing component is arranged on the top of the first aluminum foil surface layer, and the heat dissipation structure can increase the contact area between the first aluminum foil surface layer and the air when in use, which is beneficial to increasing the heat dissipation effect and heat dissipation rate of the device body, facilitating rapid heat conduction and heat dissipation, and helping to keep the pressure-sensitive adhesive layer in a high temperature state and maintaining a good service life.

[0005] Furthermore, the heat dissipation groove is in an arc shape.

[0006] Furthermore, the sealing assembly includes a second aluminum foil surface layer, which is bonded to the top of the first aluminum foil surface layer. For some special cases, the second aluminum foil surface layer is arranged on the top of the first aluminum foil surface layer to ensure the sealing effect of the upper and lower parts of the device body. The second aluminum foil surface layer and the first aluminum foil surface layer are bonded by glue and can be torn off and separated.

[0007] Furthermore, tear holes are equidistantly penetrated through the tops of the second aluminum foil surface layer, the first aluminum foil surface layer and the pressure-sensitive adhesive layer. The tear holes and the heat dissipation grooves are located on the same axis, which makes it easy to quickly segment the device body through the tear holes, and is conducive to rapid segmentation and use without the aid of tools.

[0008] Furthermore, the spacing between the heat dissipation through holes is smaller than CM.

[0009] Furthermore, the pressure-sensitive adhesive layer is made of acrylic pressure-sensitive adhesive.

[0010] Technical effects and advantages of the utility model:

This design allows the second aluminum foil surface layer to be bonded to the surface of the first aluminum foil surface layer for heat conduction when bonding and conducting heat to objects with relatively low temperatures, thereby shielding the heat dissipation structure on the surface of the first aluminum foil surface layer without affecting the integrity and sealing of the structure. The pressure-sensitive adhesive layer with good elasticity and the first aluminum foil surface layer can be easily torn off through the tearing hole, which is conducive to the use of the intercepting device body.

[0020] The working principle of the first embodiment of the utility model: when in use, the contact area between the first aluminum foil surface layer 112 and the air can be increased through the heat dissipation groove 211, thereby increasing the heat dissipation area and the heat dissipation rate. The heat dissipation through hole 210 allows the air to directly contact the flame retardant layer 111 and the first aluminum foil surface layer 112, thereby increasing the contact area between the air and the device body 100 during heat conduction and increasing the heat dissipation effect.

[0021] Embodiment 2:

[0022] The difference between the second embodiment and the first embodiment is that the sealing component 300 includes a second aluminum foil surface layer 310, and the second aluminum foil surface layer 310 is bonded to the top of the first aluminum foil surface layer 112.

When bonding and heat-conducting some objects with relatively low temperatures, the second aluminum foil surface layer 310 is bonded to the surface of the first aluminum foil surface layer 112 to block the heat dissipation structure 200 on the surface of the first aluminum foil surface layer 112, which will not affect the integrity and sealing of the structure. Through the tear holes 311, it is convenient to tear off the pressure-sensitive adhesive layer 110 with better elasticity and the first aluminum foil surface layer 112, which is conducive to the use of the intercepting device body 100.
