▎ 摘  要

NOVELTY - Cable comprises cable core (2) provided with a conductor. A surface of the conductor is formed with a protective layer. An outer area of the conductor is covered with a mica tape. A surface of the mica tape is formed with an insulating layer. An inner area of the mica tape and an outer area of the protective layer are filled with a filler. A surface of the cable core is covered with a shielding protective net (3). An inner wall of a protective sleeve (1) is contacted with a surface of a reinforcing rib (4) and an elastic rubber belt (5). USE - Cable. ADVANTAGE - The cable has high wear resistance and ductility, has strong extensibility. The reinforcing rib can greatly improve tensile property. The elastic rubber belt is used for fixing the reinforcing rib, thus avoiding the phenomenon that the reinforcing rib is loose in the process of cutting the cable. The conductor material prepared by the method has good extending performance, thus that it will not be damaged caused by extruding and in the actual use process. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a cable with high wear resistance and ductility, which involves: (A) preparing conductor by mixing appropriate amounts of aluminum, magnesium, copper and iron and then smelting to obtain mixture A, adding appropriate amounts of zinc, silicon and manganese to mixture A for smelting to obtain mixture B, at 35-45 degrees C, polishing the surface of mixture B smoothly, and then performing preliminary annealing treatment at 200-300 degrees C temperature for 30-50 seconds, obtaining the conductor prototype, twisting the conductor prototype, and twisting at least seven conductor prototypes to form a conductor, cleaning the surface of conductor with an appropriate amount of deionized water, and then placing the cleaned conductor in a drying box for drying at 60-80 degrees C for 20-40 minutes, taking out and placing at room temperature; (B) mixing acidic silica sol and palladium hydroxide, stirring quickly, after aging at room temperature for 4-5 hours, preparing a modified silica sol, and adding the silicone adhesive to 0.08-0.1 times weight of modified silica sol, mixing and stirring to obtain silicone hybrid binder, spraying the modified liquid on both sides of the mica paper, drying, and then straightening the mica paper, brushing the prepared silicone mixed adhesive on reverse side, then spreading the glass fiber cloth on the front and back of mica paper, putting it in the oven, and drying it to obtain the mica tape; (C) crushing the glass fiber reinforced polypropylene composite waste into 0.8 mm glass fiber reinforced polypropylene particles through a crusher, and then taking an appropriate amount of phenolic resin, aminopropyltriethoxysilane, methyltrichlorosilane and acetone, pouring them into a mixture equipped with glass fiber reinforced polypropylene particles, starting the mixer, setting the temperature to 190-220 degrees C for 1-2 hours, making the raw materials fully mixed uniformly, then adding the appropriate amount of polyethylene, antioxidants and anti-aging agents, continue stirring and mixing, then adding the mixture to the open mill, mixing uniformly and transferring to the twin-screw extruder For extrusion, heating the material to 155 degrees C with a vacuum plate vulcanizer to obtain the raw material of the insulating layer; (D) coating the surface of conductor with a layer of graphene paint to form a protective layer, and then using the mica tape to combine multiple conductor wrapped, and then pouring the insulating layer into the extruder, and forming the insulating layer on the surface of mica tape by extrusion, using polyurethane foam filled between the mica tape and conductor to form a filler; (E) selecting appropriate amount of silicone resin, polyvinyl chloride resin and zinc stearate and pouring into the blender, mixing at 200-300 degrees C for 1-2 hours to fully melt and mix, then adding appropriate amount of emery, deionized water, silane coupling agent, EPDM rubber, plasticizer, flame retardant and antioxidant, and continue stirring at 220-350 degrees C for 2-3 hours, and obtaining the sheath raw materials; (F) using the shielding protective net made of thin wires of copper-aluminum alloy material to wrap the 8 cable cores, uisng reinforcing ribs on the surface of shielding protective net for reinforcement, using elastic rubber bands to connect the reinforcing ribs to reinforce the cable core, and then filling the insulating rubber particles into void formed by the shielding protective net and cable core in the cavity; and (G) forming the filling layer, pouring the raw material of sheath into the extruder, and extruding the shielding protective net reinforcement and elastic rubber band formed on the surface of the sheath, and obtaining the cable.
