Description

Technical Field

[0001] This utility model relates to the field of thermally conductive adhesive tape technology, specifically to a flame-retardant easy-tear adhesive tape. Background Technology

[0002] With the rapid development of the electronics industry, electronic products are becoming lighter and smaller, resulting in higher integration of electronic components. Consequently, the requirements for the thermal conductivity and heat dissipation performance of electronic components are becoming increasingly stringent. Thermally conductive adhesive tapes are widely used due to their combined thermal conductivity and adhesion functions. Furthermore, their flexibility, compressibility, conformability, and wide temperature range allow them to occupy a significant share of the thermally conductive materials market.

[0003] Currently available thermal conductive adhesive tapes incorporate thermally conductive fillers into the adhesive to achieve heat conduction. However, these tapes typically have a low thermal conductivity, and since the base material is usually made of foam, they are prone to catching fire. Furthermore, the tapes are difficult to find openings on rollers and are not easy to tear, making their use very inconvenient. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a flame-retardant and easy-tear adhesive tape that has good heat dissipation performance, flame retardant properties, and easy-tear function, making it very convenient to use.

[0005] The technical solution of this utility model is as follows:

[0006] A flame-retardant easy-tear adhesive tape includes a roller and an adhesive tape wound on the roller. The adhesive tape is composed of several adhesive patches, with an easy-tear area between adjacent adhesive patches. The outer surface of the easy-tear area is provided with easy-tear lines, and several equally spaced easy-tear openings are provided in a straight line on the easy-tear area. Each adhesive patch includes a heat dissipation layer, a flame-retardant layer, a foam layer, and an adhesive layer. The flame-retardant layer surrounds the foam layer, the heat dissipation layer is disposed on the upper surface of the flame-retardant layer, and the adhesive layer is disposed on the lower surface of the flame-retardant layer.

[0007] Furthermore, the first adhesive patch also has an easy-tear area at its tip.

[0008] Furthermore, the heat dissipation layer is a graphite heat dissipation layer.

[0009] Furthermore, the graphite heat dissipation layer has several evenly distributed heat dissipation holes.

[0010] Furthermore, the flame-retardant layer is made of polyvinyl chloride.

[0011] Furthermore, the foam layer contains embedded fiber filaments.

[0012] Furthermore, the fibers have a triangular wavy structure.

[0013] Furthermore, the adhesive layer is a flame-retardant adhesive.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] (1) The adhesive tape of this utility model is composed of several adhesive patches, and an easy-tear area is provided between two adjacent adhesive patches. The outer surface of the easy-tear area is provided with easy-tear lines, and several equally spaced easy-tear openings are provided in a straight line on the easy-tear area. This structural design makes the adhesive very easy to tear. When using it, you can tear open the easy-tear area between two adjacent adhesive patches to get an adhesive patch. It is very convenient to use. At the same time, the head end of the first adhesive patch is also provided with an easy-tear area, and after each adhesive patch is torn off, the head end of the next adhesive patch will have a part of the easy-tear area remaining, thereby overcoming the problem of finding the opening of the adhesive tape.

[0016] (2) The adhesive patch of this utility model includes a heat dissipation layer, a flame retardant layer, a foam layer and an adhesive layer; wherein, the heat dissipation layer is a graphite heat dissipation layer, and a number of evenly distributed heat dissipation holes are opened on the graphite heat dissipation layer, so that the adhesive patch has a good heat dissipation effect and can avoid the impact on the performance of electronic devices due to excessive heat concentration; the outer layer of the foam layer is surrounded by a flame retardant layer, which is made of polyvinyl chloride and has excellent flame retardant properties, and triangular wave structure fiber filaments are built into the foam layer to enhance the tensile strength and tear resistance of the adhesive patch; the adhesive layer uses flame retardant adhesive, which further improves the flame retardant performance of the adhesive patch.

[0027] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0028] Example

[0029] Please see Figure 1 This embodiment provides a flame-retardant easy-tear adhesive tape, including a roller 1 and an adhesive tape 2 wound on the roller 1. The adhesive tape 2 is composed of several adhesive sheets 21, with an easy-tear area 22 between adjacent adhesive sheets 21. The outer surface of the easy-tear area 22 has easy-tear lines, and several equidistant easy-tear openings 221 are linearly distributed on the easy-tear area 22. This structural design makes the adhesive tape very easy to tear. In use, simply tear the easy-tear area between two adjacent adhesive sheets 21 to obtain an adhesive sheet, which is very convenient. Preferably, the first adhesive sheet 21 also has an easy-tear area 22 at its beginning. After each adhesive sheet 21 is torn off, the beginning of the next adhesive sheet 21 will have a portion of the easy-tear area remaining, thus overcoming the problem of difficulty in finding the opening of the adhesive tape.

[0030] Combination Figure 2 As shown, each adhesive patch 21 includes a heat dissipation layer 211, a flame retardant layer 212, a foam layer 213, and an adhesive layer 214. The flame retardant layer 212 surrounds the foam layer 213. This flame retardant layer 212 is made of polyvinyl chloride and provides excellent flame retardant properties for the adhesive patch while protecting the flammable foam layer. The heat dissipation layer 211 is located on the upper surface of the flame retardant layer 212. This heat dissipation layer 211 is a graphite heat dissipation layer with several evenly distributed heat dissipation holes, giving the adhesive patch good heat dissipation and preventing the impact of excessive heat concentration on the performance of electronic devices. The adhesive layer 214 is located on the lower surface of the flame retardant layer 212. This adhesive layer 214 is a flame retardant adhesive, further improving the flame retardant properties of the adhesive patch.

[0031] Furthermore, the foam layer 213 also contains embedded fiber filaments 215, which have a triangular wavy structure. This enhances the tensile and tear strength of the adhesive patch.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
