Processing method of waterproof boiling-resistant cable and waterproof boiling-resistant cable

Abstract

The invention discloses a processing method of a waterproof boiling-resistant cable and the waterproof boiling-resistant cable, and the waterproof boiling-resistant cable comprises a metal inner coreand an insulating layer, wherein the insulating layer wraps the outer side of the metal inner core to form a plurality of unit wires, and all the unit wires are spirally wound to form a main cable; the outer side of the main cable comprises an outer sheath. According to the invention, the unit wires are spirally wound, thereby improving the waterproof performance of the cable; the thermal stability of the PVC is improved by adding the filler into the PVC, and the flame-retardant and anti-aging performance of the outer sheath is improved by adding the flame-retardant components aluminum hydroxide and magnesium hydroxide, adding the zinc stearate as the lubricant and adding the triphenyl phosphite as the antioxidant. Cold water is input through the water inlet pipe, cooled through the circulating water pipe and discharged through the water discharging pipe, the temperature can be kept constant, and the extrusion effect is improved.

Description

technical field [0001] The invention relates to the technical field of power cables, in particular to a processing method for a waterproof and boiling-resistant cable and a waterproof and boiling-resistant cable. Background technique [0002] Wires and cables are wire products used to conduct current. Their structure is generally made of a metal material with high conductivity, and the inner core is wrapped with a plastic sheath. [0003] The current electric wires and cables are made of PVC resin (polythene) powder, plasticizer (plasticize), filler (loading agent), slip agent, stabilizer, toner and other ingredients according to the established ratio of the industry. [0004] The publication number CN108766667A discloses a preparation method of a cable, but in the preparation method of the cable, the unit wire is not helically wound, resulting in poor waterproof performance of the cable, while the thermal stability of the cable is poor, and the flame retardant and anti-oxid...

Problems solved by technology

[0004] The publication number CN108766667A discloses a preparation method of a cable, but in the preparation method of the cable, the unit wire is not helically wound, resulting in poor waterproof performance of the cable, while the thermal stability of the cable is poor, and the flame retardant and anti-oxidation properties of the outer sheath In the process of extrusion granulation, the constant extrusion temperature cannot be guaranteed, resulting in poor extrusion effect, and the mixed particles after extrusion cannot be screened; the outer sheath is injection molded in the mold During the molding process, it is necessary to manually remove the molding outer sheath, which wastes time and reduces work efficiency
