Embodiment 1

[0018] Embodiment 1: The manufacturing method of a kind of anti-stretching and tearing electric wire provided by this embodiment comprises the following steps:

[0019] S1: Core wire preparation, the bare copper wire and multi-strand nylon wire are passed through the hole of the distribution board into the inner mold, and the multi-strand nylon wire is evenly wrapped around the bare copper wire to form a wire, and the insulation is formed around the outer circumference of the wire by extrusion layer to get the core wire; in order to increase the bending resistance of the wire, nylon wire is filled around the conductor, adding nylon wire is accompanied by possible problems and solutions, such as wire foaming, nylon ribbon with moisture, heating the side of the machine before extrusion Blow and heat, or dry for 2 hours first; or shrink the nylon wire to reduce the tension of the pay-off wire. The nylon wire is eccentric to one side. For this reason, the nylon wire is evenly place...

Embodiment 2

[0024] Embodiment 2: The manufacturing method and the wire of a kind of anti-stretching and tearing electric wire provided by this embodiment are basically the same as Embodiment 1, the difference is that the nylon filament added to the conductor contains repeated amides on the main chain of the molecule Long fibers or short fibers made of thermoplastic resin materials with the group -NHCO-. Preferably, the nylon filament is made of the following components in parts by weight: 50 parts of block copolymerized polyamide 6, 20 parts of polyethylene carbonate, 10 parts of silane coupling agent, and 5 parts of antioxidant; Wherein the block copolymerized polyamide 6 is a polyamide 6 type thermoplastic elastomer with a segmented block copolymer structure, which is synthesized by a two-step method, first synthesizing a double-terminal carboxyl-terminated PA6 prepolymer, and then combining it with PTMG ( Polyamide 6 thermoplastic elastomer produced by polyesterification reaction of po...

Embodiment 3

[0025] Embodiment 3: The manufacturing method and the wire of a kind of anti-stretching and tearing electric wire provided by this embodiment are basically the same as Embodiment 1, the difference is that the nylon filament added to the conductor contains repeated amides on the main chain of the molecule Long fibers or short fibers made of thermoplastic resin materials with the group -NHCO-. Preferably, the nylon filament is made of the following components by weight: 60 parts of block copolymerized polyamide 6, 15 parts of polyethylene carbonate, 10 parts of silane coupling agent, and 2 parts of antioxidant; Wherein the block copolymerized polyamide 6 is a polyamide 6 type thermoplastic elastomer with a segmented block copolymer structure, which is synthesized by a two-step method, first synthesizing a double-terminal carboxyl-terminated PA6 prepolymer, and then combining it with PTMG ( Polyamide 6 thermoplastic elastomer produced by polyesterification reaction of polytetrahy...

Abstract

The invention discloses a manufacturing method of an anti-pulling and anti-tearing foot-stepping wire and a wire thereof. The method comprises the steps of penetrating a bare copper wire and a plurality of nylon wires into an internal mold through the wire distribution plate holes, enabling the plurality of nylon wires to uniformly surround the bare copper wire to form the wire, and extruding to form an insulating layer at the periphery of the wire so as to obtain a core wire; extruding on the outer surface of the core wire to form an outer sheath layer, thereby obtaining the anti-pulling andanti-tearing foot-treading wire. According to the invention, by adding the nylon wire material with excellent resilience, high temperature resistance, solvent resistance, weather resistance and the like and the excellent insulating layer, the anti-pulling, anti-swinging, anti-bending, anti-pulling, anti-tearing and anti-treading performances of the conductors and the wires are improved, the service life of the wires in the shoe sole is prolonged, and the defects of wire foaming, nylon wire retreating and the like after the nylon wires are increased are overcome by combining the manufacturing method.

Description

technical field [0001] The invention relates to the technical field of electric wires, in particular to a method for manufacturing a tensile and tear-resistant pedal electric wire and the electric wire. Background technique [0002] Light-up shoes on the market, that is, shoes with light on them, are fun for children to wear, and adults can also wear them when going out at night, just like the reflective clothing on traffic police, which play a role in safety. However, because the wire is not resistant to tearing and swinging, the energized conductor is disconnected after a short time, so that the light of the newly bought shoes will not light up after a long time of wearing. In order to solve this difficult problem, some existing methods are to increase the thickness of the insulating layer of the wire rod, which can prolong the service life, but the disadvantage is to increase the sole, increase the weight, and reduce the comfort of wearing shoes. In view of this, the pre...
