The reinforcing layer and the toughness layer are bonded together with epoxy resin adhesive. Both the first wear-resistant layer 12 and the second wear-resistant layer 13 are polytetrafluoroethylene (PTFE) coatings. PTFE has excellent wear resistance and corrosion resistance, which can reduce frictional wear between the strap body 1 and the battery casing and mounting bracket, and extend service life. The layers are bonded together using a special PTFE primer and spray curing. First, a PTFE coating is applied to the surface of the aramid fiber braided layer. This primer can penetrate into the limiting gaps and cure to form a transition layer. After the primer has cured, PTFE powder is evenly sprayed onto the primer surface using an electrostatic spraying process. The spraying thickness is controlled at 0.3-0.5 mm. After spraying, the coating is placed in a high-temperature furnace and sintered at 380-420℃ for 30-40 minutes to melt the PTFE powder into a continuous coating and completely fuse it with the primer transition layer.
