[0028] Example 1, as Figure 1-4As shown, the insulating double-sided pressure-sensitive tape includes a tape body 1 and two release papers 2. The tape body 1 is arranged between the two release papers 2. Auxiliary devices 3 are provided on both sides of the tape body 1 and the release papers 2. The auxiliary devices 3 include several rectangular blocks 33. Grooves 31 are provided on both sides of the tape body 1 and the release papers 2. Several rectangular holes 32 are provided on one side of the tape body 1 and the release papers 2. Connecting blocks 34 are fixedly connected to both sides of the rectangular blocks 33. One side of the connecting block 34 is fixedly connected to both sides of the inner wall of the groove 31. When the tape body 1 and the release paper 2 are torn apart for use according to the requirements, since grooves 31 are provided at the edges of both sides of the tape body 1 and the release paper 2, and the interior is connected by several thin rectangular blocks 33 and connecting blocks 34, you can hold the edges on both sides of the groove 31 with both hands and pull them in opposite directions to easily tear them apart. Then, several rectangular holes 32 can reduce the connection area between the tape body 1 and the release paper 2, so that the tape body 1 and the release paper 2 can be torn into corresponding sizes according to the requirements of use, which is convenient for the use of the tape body 1 and avoids waste during use.
[0029] Reference Figure 2 and Figure 3 As shown, this embodiment discloses a groove 31 having a triangular cross-section, with the sharp end of the groove 31 positioned near one side of the rectangular hole 32. The triangular shape of the groove 31 concentrates the tearing force in one location, facilitating tearing and thus facilitating the use of the tape body 1. A plurality of circular holes 35 are formed on one side of the rectangular block 33, arranged at equal distances. The provision of the circular holes 35 reduces the connecting area between the rectangular blocks 33, making it easier to tear the tape body 1 apart when pulling it left and right.
[0030] Reference Figure 2 and Figure 3 As shown, this embodiment discloses a plurality of operating blocks 36 symmetrically fixedly connected to both sides of the release paper 2. Two operating blocks 36 are provided on either side near the opening of the groove 31. The provision of operating blocks 36 facilitates manually grasping the edges of the release paper 2 to remove it from the tape body 1 after the tape body 1 and release paper 2 are torn apart. A plurality of rubber bumps 37 are fixedly connected to both sides of the operating blocks 36. The provision of bumps 37 increases the contact friction between the two sides of the operating blocks 36, making it more secure and less likely to slip when manually grasped and pulled.
[0031] Reference Figure 4As shown, this embodiment discloses a tape body 1 including a first base layer 11, which is made of polyimide. Polyimide is a high-performance polymer material with excellent high-temperature resistance, chemical corrosion resistance, and electrical insulation properties, which gives the tape body 1 good high-temperature resistance, chemical corrosion resistance, and electrical insulation properties. Second base layers 12 are provided on both sides of the first base layer 11, and the second base layers 12 are made of non-woven fabric. Non-woven fabric is a non-woven fabric material composed of interwoven fibers with excellent insulation properties and flexibility, which gives the tape body 1 good insulation effect and flexibility.
[0032] Reference Figure 4 As shown, this embodiment discloses pressure-sensitive adhesive layers 13 disposed on both sides of the second base layer 12. Pressure-sensitive adhesive layers 13 are made of acrylic. Acrylic adhesives offer strong coating adaptability, fast drying, and strong adhesion. Furthermore, acrylic pressure-sensitive adhesives have excellent low- and high-temperature resistance, maintaining stable adhesion under extreme temperature conditions.
[0033] Working principle: when the tape main body 1 and the release paper 2 are torn apart for use according to the needs, since grooves 31 are opened on the edges of both sides of the tape main body 1 and the release paper 2, and the interior is connected by several thin rectangular blocks 33 and connecting blocks 34, you can hold the edges on both sides of the groove 31 with both hands and pull them in opposite directions to easily tear them apart. Then, several rectangular holes 32 can reduce the connection area of the tape main body 1 and the release paper 2, so that the tape main body 1 and the release paper 2 can be torn into corresponding sizes according to the needs of use, which is convenient for the use of the tape main body 1 and avoids waste during use. When using the torn tape main body 1, you can hold the operating block 36 and the protrusion 37 and pull them to one side to tear off the release paper 2 on one side of the tape main body 1, so that the tape main body 1 can be adhered to the object for use.
[0034] When producing the tape body 1, the first base layer 11 and the second base layer 12 can be adhered together with the help of a machine to improve the high temperature resistance, chemical corrosion resistance, insulation effect, flexibility and electrical insulation performance of the tape body 1, and at the same time, a pressure-sensitive adhesive layer 13 is coated on both sides of the second base layer, so that it also has excellent low temperature resistance and high temperature resistance, can maintain stable bonding performance under extreme temperature conditions, and is easy to use.
