▎ 摘　　要

NOVELTY - A torsion-resistant robot arm cable comprises a conductive wire core, a shielding layer and a sheath layer from inside to outside. The gap between the shielding layer and conductive wire cores is filled with elastic foaming material comprising 60-70 pts. wt. natural rubber, 17-25 pts. wt. polyolefin elastomer, 1-3 pts. wt. graphene, 2-4 pts. wt. crosslinking agent, 1-3 pts. wt. foaming agent, 3-5 pts. wt. heat stabilizer, 2-4 pts. wt. polyethylene wax and 4-6 pts. wt. polytetrafluoroethylene fiber. USE - As torsion-resistant robot arm cable. ADVANTAGE - The torsion-resistant robot arm cable has excellent torsion resistance during long-term three-dimensional torsion, bending and high-intensity exercise, and is not prone to breakage during the process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of the torsion-resistant robot arm cable comprising (S1) preparing raw materials containing natural rubber, polyolefin elastomer, graphene, a crosslinking agent, a foaming agent, a heat stabilizer, polyethylene wax and polytetrafluoroethylene fibers according to a ratio, (S2) twisting conductive wire core stranded wires, placing the twisted conductive wire core stranded wires in a foaming mold, mixing the raw materials in the step (S1), melting and extruding, foaming the surfaces of the conductive wire cores to form an elastic foaming material, spirally and densely winding the conductive wire cores by a shielding wire in an anticlockwise direction to form an inner shielding sleeve, spirally and densely winding the inner shielding sleeve by a shielding strip in a clockwise direction to form an outer shielding sleeve, and forming a shielding layer by the inner shielding sleeve and the outer shielding sleeve, and (S3) coating the cable core with the shielding layer by a sheath layer to obtain the product.
