Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a flame retardant and high temperature resistant insulating adhesive tape. Background Art

[0002] Insulating tape is a kind of tape with insulating function, usually used in wire connection, electrical insulation, heat insulation protection and other occasions.

[0003] In electrical equipment, it is inevitable to work in a high temperature environment during use. High temperature environment will accelerate the aging and damage of insulating materials. At the same time, insulating materials with poor heat resistance will soften, deform or even burn during long-term use, affecting the use effect and safety. In some high-voltage power settings, in order to ensure safety, there are higher requirements for the performance of insulating tapes. At the same time, the power industry inevitably generates a lot of heat. In order to ensure the stability and safety of the performance of insulating tapes, it is also necessary to give the insulating tapes good heat resistance and flame retardancy.

[0004] At present, it is inevitable to use it in a high temperature environment when it is used in electrical equipment. Since the aging of the insulating material will be accelerated in a high temperature environment, it is easy to cause the insulating tape to soften, deform, or even burn. In addition, the current insulating tape has poor corrosion resistance. When used in a corrosive environment, it is easy to be damaged by corrosion. Therefore, we need to propose a flame-retardant and high-temperature resistant insulating tape. Utility Model Content
