[0002] Adhesive tape has been used in all walks of life and in people's daily life. Adhesive tape is a polymer material that acts as a bond by applying adhesive to the surface of the substrate. Adhesive tape has a huge application in industries such as coal, steel, cement, ports, mining, petroleum, automobiles, textiles, light industry, and machinery. According to different functions, it is suitable for different places and fields. It can be divided into high-temperature tape, double-sided tape, anti-slip tape, special tape, pressure-sensitive tape, die-cut tape, and flame-retardant tape.

[0003] For example, the Chinese patent document with publication number CN103642418A, whose patent name is flame retardant tape, mentions that "the flame retardant tape includes an uppermost layer, a middle layer and a lowermost layer, the uppermost layer is polyester glass fiber cloth, the middle layer is acrylic adhesive, and the lowermost layer is epoxy resin, the polyester glass fiber cloth accounts for 47%-51% of the weight of the flame retardant tape body, the acrylic adhesive accounts for 20%-27% of the weight of the flame retardant tape body, and the epoxy resin accounts for 23%-28% of the weight of the flame retardant tape body". This structure has the advantages of good flame retardancy, heat resistance and no irritating odor.

[0004] Therefore, an anti-static flame-retardant adhesive tape is urgently needed to solve the above problems. Utility Model Content
