Problems solved by technology

Among them, the core wire insulation layer is distinguished by the color ring, which needs a color ring process after extrusion molding, so its disadvantage is that there are many processes and low efficiency.
Another core wire insulation layer distinguished by color edge requires high equipment requirements, so its disadvantages are large investment, high equipment cost, and complicated process technology

Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0014] The main feature of the manufacturing process of the data cable core wire insulation layer of the present invention is the adjustment of the color masterbatch ratio, and all the other processes including feeding, melting, homogenization, extrusion molding, etc. are using known production processes, so Only a brief description is given here.

[0015] The colors of the four twisted core wires of the current data cable are blue, white, orange, white, green, white, brown, and white, and the four white main core wires are respectively equipped with blue, orange, green, and brown wires. Color circle or color edge to distinguish. Now by adjusting the ratio of the color masterbatch, it is directly extruded into an insulating layer of light blue 12, light orange 22, light green 32, and light brown 42 colors, replacing the four white main core w...

Abstract

Insulating layer is prepared through procedures: proportioning, loading, fusing, homogenizing and extrusion molding. If portion by weight of base material is 100, then proportioning of color parent material is as following: light blue is prepared from base material 100 portion, white parent material 0.6-1.5 portion, and blue parent material 0.2-0.5 portion; similarly, light orange, light green and light brown can be prepared. Adjusting proportioning of color parent material makes colors of twisted wires become as blue, light blue, orange, light orange, green, light green, brown and light brown so as to reach purpose of identifying wires easily. Features are: reduced production steps, raised production efficiency, and improved properties of products etc.

Description

technical field [0001] The invention relates to a manufacturing process of an insulating layer of a data cable core wire, in particular to a manufacturing process for manufacturing a data cable core wire insulating layer capable of distinguishing four white main wire cores with a simplified production process. Background technique [0002] At present, the core wires of data cables use color edges or color rings to distinguish four white main cores, namely blue, white (blue), orange, white (orange), green, white (green), brown, white (brown). Among them, the insulating layer of the core wire which is distinguished by the color ring requires a process of applying a color ring after extrusion molding, so the disadvantage is that there are many processes and low efficiency. Another core wire insulation layer distinguished by color edge requires high equipment requirements, so its disadvantages are large investment, high equipment cost, and complicated process technology.
