Abstract

The invention discloses a high-flexibility shielding cable for a drag chain and a manufacturing method thereof and belongs to the field of cables. An oil-resisting rubber insulating layer is extruded on the periphery of a stranded copper conductor, so as to form an insulating core wire; a plurality of insulating core wires are stranded into an insulting core wire beam; multiple strands of insulting core wire beams are arrayed around a high-elasticity anti-torque reinforcing core and are stranded into a cable core; an oil-resisting inner jacket, a mixed knitted shielding layer and an oil-resisting outer jacket are arranged on the periphery of the cable core; and the insulating layer comprises the following raw materials by weight part: 15 parts of ethylene propylene rubber K21, 15 parts of chlorinated polyethylene rubber CM3 52, 0.5-0.6 parts of DCP (Dibasic Calcium Phosphate), 0.2-0.3 parts of TAIC (Tri-Allyl Iso-cyanurate), 0.3-0.5 parts of anti-aging agents MB, 0.1-0.3 parts of anti-aging agents RD, 1.0-2.0 parts of paraffin oil, 1-2 parts of chlorinated paraffin-52, 0.5-1.0 part of microcrystalline wax, 1.5-2.5 parts of active magnesium oxide, 0.4-0.7 parts of calcium stearate, 10-15 parts of superfine talcum powder, 1-2 parts of gaseous phase white carbon black, 6-8 parts of roasted argil and 0.2-0.4 parts of coloring agent. The high-flexibility shielding cable is excellent in insulating and mechanical properties and is oil-resisting.

Description

technical field [0001] The invention relates to a cable, in particular to a highly flexible shielded cable for drag chains; the invention also relates to a manufacturing method for a highly flexible shielded cable for drag chains. Background technique [0002] At present, the cables used in the towline system are mostly layered cables with extruded tube sheaths. During use, the cables bend and move together with the towlines, which often causes the internal bending stress of the cables to be difficult to eliminate, the wire core breaks, and the sheath surface cracks. Wrinkled, twisted and deformed, which affects the service life and operation safety; at the same time, due to the open-air construction, the towline cable is easy to contact with equipment oil, which accelerates aging and shortens the service life. The existing cable uses ethylene-propylene rubber insulation material to make the insulation layer in consideration of flexibility. However, ethylene-propylene rubber...
