Abstract

The invention relates to a method for manufacturing a special material for cables, in particular to a method for preparing a cable material for self-repairing electromagnetic shielding cables. A kind of cable material for self-healing electromagnetic shielding cable is mixed with rubber premix, mixed nanoparticles, serpentine powder, microcrystalline wax, anti-aging agent RD, sodium dodecylbenzene sulfonate, vulcanizing agent DCP and accelerator M made. The self-healing of the present invention can be completed many times, and can be completed at room temperature without external stimulation; the hybrid nano-particles not only play a reinforcing role, but also play a role of absorbing electromagnetic waves; Large-scale application; it can be used to produce ungrounded shielded cables, and it can play the role of sheath and shield at the same time; it can also be used to produce the sheath of traditional shielded cables to enhance the shielding effect.

Description

technical field [0001] The invention belongs to the technical field of functional materials, and relates to a method for manufacturing a special material for cables, in particular to a method for preparing a cable material for self-repairing electromagnetic shielding cables. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry. With the continuous expansion of the scale of China's electric power industry, data communication industry, urban rail transit industry, automobile industry and shipbuilding industry, the demand for wire and cable will also rapidly increase. Growth, the future wire and cable industry has huge potential for development. [0003] Shielded cables usually refer to signal transmission lines that still have high-quality transmission performance in strong electromagnetic interference environments. Shielding has two meanings: 1) Shielding the electromagnetic radiation caused by the in...
