A method for making multi-color silica gel doubling wires and wires thereof

Abstract

The invention discloses a multi-color silica gel doubling manufacturing method and an electric wire thereof. The method comprises the following steps: stranding a plurality of strands of tinned copperwires to form a conductor; obtaining insulating layers with different colors by extruding a prepared insulating agent outside the conductor, so that single core wires with different colors is formed;extruding the four wires at the same time, extruding the single core wires with different colors on the outer surface to form single core wires with protective layers, sequentially arranging and perforating the plurality of single core wires with different colors through a guide wheel, doubling the single core wires with different colors, feeding the single core wires into an inner mold, and doubling the plurality of single core wires with different colors through secondary extrusion to form the multi-color silica gel doubled wire with a transparent sheath layer. According to the invention, insulating flat cables with various colors can be formed to facilitate color distinguishing, have a good identification effect, greatly reduce the problems that circuits are messy and time is consumedfor searching, an excellent insulating layer and an excellent transparent outer sleeve layer are formed through compounding of optimized raw material components, the service life is greatly prolonged,and the problems of eccentricity or material shortage and the like during doubling extrusion are further avoided.

Description

technical field [0001] The invention relates to the technical field of electric wires, in particular to a method for manufacturing multi-color silicone parallel wires and electric wires thereof. Background technique [0002] At present, the parallel lines appearing on the market are basically extruded by the same color extruder. Due to the limitation of the machine, at most two colors can be formed at one time, similar to the yellow / green ground line, and more than two colors cannot be carried out, or Use parallel glue on the market for bonding, but this is inefficient, and issues such as tensile strength must also be considered. [0003] In view of this, it is indeed necessary to provide a multi-color silica gel doubling method and its wires with excellent properties such as simplicity, large-scale promotion, high efficiency, and high tensile strength. Contents of the invention [0004] The purpose of the present invention is to provide a multi-color silica gel parallel ...
