[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] Reference Figure 1 A pipe wrapping tape with a visual mark includes a base layer 1. The base layer 1 is made of polyethylene. Polyethylene has good chemical stability and can withstand dilute nitric acid, dilute sulfuric acid and any concentration of hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, ammonia water, amines, hydrogen peroxide, sodium hydroxide, potassium hydroxide and other solutions at room temperature. It has good corrosion resistance.

[0025] The bottom and the upper end of the base layer 1 are respectively provided with a first connecting layer 2 and a second connecting layer 4, the material of the first connecting layer 2 and the second connecting layer 4 is hot melt adhesive, which is conducive to connecting with the base layer 1; the bottom of the first connecting layer 2 is provided with an adhesive layer 3 for winding connection.

[0026] An anti-corrosion layer 5 is provided at the upper end of the second connecting layer 4. The material of the anti-corrosion layer 5 is polypropylene, which is a thermoplastic synthetic resin with excellent performance. It is a colorless, translucent thermoplastic lightweight general-purpose plastic with chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high-wear resistance processing performance.

[0027] A solid epoxy coating 6 is provided at the upper end of the anti-corrosion layer 5, and a groove 7 is provided at the upper end of the anti-corrosion layer 5. An identification film 8 is affixed to the groove 7. The identification film 8 is connected to the groove 7 by glue, and the size of the identification film 8 is matched with the groove 7. When the pipe wrapping tape is wound, the identification film 8 is not located in the groove 7 at this time, so that the groove 7 can increase the friction force of the pipe wrapping tape, so that the stability after winding is better. After the winding is completed, the identification film 8 is affixed to the groove 7 so that the staff can understand the pipeline information.
