Description

Technical Field

[0001] This utility model relates to the technical field of double-sided tape, specifically to a flame-retardant and heat-dissipating double-sided tape. Background Technology

[0002] Currently, with the development of various industries, the demand for double-sided tape is increasing, and the requirements for double-sided tape are also becoming more stringent, especially in the electronics industry. Double-sided tape is classified into several categories according to its use: water-based double-sided tape, oil-based double-sided tape, hot melt adhesive double-sided tape, embroidery double-sided tape, and printing plate mounting double-sided tape. Water-based double-sided tape has weaker adhesion, while oil-based double-sided tape has stronger adhesion. Hot melt double-sided tape is mainly used in stickers, stationery, and office supplies. Oil-based double-sided tape is mainly used in high-adhesion applications such as leather goods, pearl cotton, sponges, and footwear. Embroidery double-sided tape is mainly used in computer embroidery, and printing plate mounting tape is mainly used for mounting and positioning printing plates.

[0003] Patent publication number CN205615173U discloses "a double-sided adhesive tape," the key technical points of which include a base layer, several double-sided adhesive layers neatly arranged on the base layer, and protective layers equal in number to the double-sided adhesive layers and covering them. The double-sided adhesive layers have a shape adapted to the bonding area, and the double-sided adhesive layers can be of any shape. The protective layer includes a protective part of the same size as the double-sided adhesive layers and a handle integrally connected to the edge of the protective part. When peeled off using the handle, the double-sided adhesive layers and the protective layer are detached from the base layer together. The protective layer carries the double-sided adhesive layers to the part to be bonded. Since one side of the double-sided adhesive layer is already bonded to the part, the adhesive force between them is definitely greater than the adhesive force between the double-sided adhesive layer and the protective layer. Therefore, when the protective layer is then removed... The protective layer is removed, allowing another component to be bonded to the other side of the double-sided adhesive layer. Both sides of the double-sided adhesive layer are adhesive. As a carrier for multiple double-sided adhesive layers, the base layer protects one side of the double-sided adhesive layer and supports multiple layers, while the protective layer protects the other side. Since the shape of the double-sided adhesive layer matches the shape of the protective part, there is no double-sided adhesive layer bonded to the handle. Therefore, under normal circumstances, there is a gap between the handle and the base layer. The handle is also integrally connected to the edge of the protective part, allowing the double-sided adhesive layer to be removed from the base layer and applied to the component that needs to be bonded. However, its flame retardancy is poor. In the electronics industry, due to the high temperature, ordinary double-sided adhesive can easily cause fires and other problems. Furthermore, its strength is not high, its tensile strength is poor, and it is easily damaged. To address the aforementioned issues, publication number CN202223330492.X discloses a flame-retardant double-sided adhesive. Its outer layer ensures adhesion and flame retardancy on both sides of the main body layer. The adhesive layer increases the adhesion of the main body layer, the flame-retardant layer increases its flame retardancy, the toughness layer increases its toughness, the tensile layer increases its tensile strength, and the reinforcing layer increases its strength. This solves the problems of poor flame retardancy in existing double-sided adhesives, which can easily cause fires in electronic components due to high temperatures, and the low strength, poor tensile properties, and susceptibility to damage.

[0004] However, the above-mentioned double-sided tape still has the following problems: 1. The heat dissipation effect of the existing double-sided tape is poor, and it cannot effectively dissipate heat from one or two objects on the end face as needed, which limits its applicability; 2. The existing double-sided tape is difficult to peel off the adhered object after bonding, resulting in residue, increasing the steps of subsequent processing, and affecting the efficiency of object installation or maintenance.

[0026] Both the contact heat-conducting layer 50 and the heat-dissipating layer 51 are made of thermally conductive silicone material. Each heat-dissipating layer 51 is provided with multiple heat dissipation grooves 510, and each heat dissipation groove 510 is provided with a slope 511.

[0027] The flame-retardant layer 3 is provided with a fire extinguishing layer 30, which is disposed on the surface of the flame-retardant layer 3.
