Abstract

The utility model relates to the improvement of a color separating cable. The utility model is characterized in that a wire core insulating layer is composed of a same color insulating layer and an outer thin color separating layer which are compound, wherein multilayer color separation causes insulating materials extruded a main extruding machine of the production line for extruding insulation to be unchanged. Different color lines only need to change the colors of the outer compound thin layer. The color materials are save the waste of insulating materials is reduced when coloring materials with large connected bodies are changed. The time of changing the outer color separation thin layer is short, and the production efficiency is basically affected. If the combined extruding machine is matched, the color change is realized under the condition of machine halt and the reduction of manufacturing cost is favorable. In addition, some auxiliary materials can be added in the color separation thin layer, and the outermost color separation layer has other corresponding functions, such as ageing resistance, flame resistance, oil resistance, wear resistance, antisepsis or acid resistance, etc. The auxiliary materials can not affect the performance of the insulating layer, and the function of the cable insulating layer is enlarged.

Description

The color separation cable

Technical field

Utility model is about the improvement to cable color separation core.

Background technology

Need owing to discerning in the wires and cables industry, often each heart yearn of cable is made different colours (color phase-splitting), the color separation core (Fig. 1) of existing different colours substantially all is to add different colorants in the Insulation Material that each core extrudes, and obtains the core of different colours insulating barrier.This defective that extrudes color separation by insulation colorant entire body is: the one, in actual production process, when extruding the replacing color, must shut down and change the extruded insulation colorant, so that cause the bigger waste of Insulation Material, and the waste of this kind Insulation Material and wire core diameter's specification are proportionate, be that core is thick more, cause the Insulation Material waste just many more; The 2nd, change Insulation Material and take the production time, cause production efficiency to reduce.

Though in the colo(u)r streak manufacture process, the color separation of the coating of employing colorant is arranged also, promptly online core insulation surface applied different colours material forms different colo(u)r streaks.But the deficiency of this coating color separation is that coating color poor adhesive force all causes coming off of coating colorant easily in production, transportation, installation, the use, influence normally identification; Secondly, apply color separation and extrude and to carry out by branch two procedures, increased production process, also can influence production efficiency; Besides, coating pigment cost is relatively large, can cause the increase of cable cost.

Summary of the invention

The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of and can satisfy cable color separation needs, does not waste the insulation colorant again substantially, and painted adhesion-tight, produces simple color separation cable.

The utility model purpose realizes, the main improvement is to change the outer entire body insulation of former conductor chromatograph into double-decker, internal layer adopts homochromy base material insulating barrier, skin is then looked and is required to extrude different colours color separation thin layer, thereby make cable both satisfy the color separation requirement, make again when changing color aborning, only need to change the few outer thin dichroic layer of the amount of extruding, it is few that colorant is changed waste, thereby cause a large amount of wastes when having avoided the colour changing of entire body insulation colorant.Specifically, utility model color separation cable comprises different colours insulating barrier core, it is characterized in that the core insulating barrier by homochromy insulating barrier with outer thin dichroic layer is compound forms.

The said insulation of utility model is double-deck, can adopt double-layer coextrusion technology to extrude, and promptly extrudes required thin dichroic layer simultaneously extruding the core insulation, and dichroic layer fits tightly combination with insulating barrier and well do not separate like this, can not influence the insulated electro performance of core.

In addition, utility model can also add some other functional material in the color separation layered material, as anti-aging, fire-retardant, oil resistant, functional material such as wear-resisting, anticorrosion or acidproof, make skin not only have color separation function, but also have the function that adds above-mentioned material, thereby enlarged the dichroic layer function, and also can avoid in insulating barrier adding some functional material and the deficiency that influences insulation property.

Utility model color separation cable, owing to adopt color separation of multiple layer and double-layer coextrusion technology, online core insulation layer extrudes thin dichroic layer outward, extruded insulation production line main extruder is extruded Insulation Material and can be remained unchanged like this, produce different colo(u)r streaks and only need change outer thin multiple layer colorant, produce simple, not only can be bigger the waste of Insulation Material during the saving colour changing, and it is short to change the outer dichroic layer time, does not influence production efficiency basically.If be equipped with the combination extruder, can accomplish not shut down colour changing, these all help the reduction of production cost.The color separation of the multiple layer of utility model do not increase operation, do not increase Insulation Material, produces simple.In addition, add some other auxiliary material in the color separation thin layer, also can make the dichroic layer of outermost have other corresponding functions, as anti-aging, fire-retardant, oil resistant, effect such as wear-resisting, anticorrosion or acidproof, and can not influence the insulating barrier performance, enlarge the cable insulation function because of adding auxiliary material.

Below in conjunction with an embodiment, further specify utility model.

Fig. 2 is utility model three a core color separation construction of cable schematic diagrames.

Embodiment

Embodiment: referring to Fig. 2, utility model three core color separation cables have the three eradication edge cores that are triangularly arranged, and fill 4, tighten layer 5 and sheath 6 compositions.Wherein each core is made up of conductor 1, homochromy insulating barrier 2, color separation thin layer 3, and insulating barrier and color separation thin layer fit tightly compound by double-layer coextrusion technology.

In addition, can add some other functional auxiliary materials as required in the color separation layered material outside, realize some specific result of use.

Other functional layers can also be added as required in cable, as screen, water blocking layer etc.

Claims (2)

1, color separation cable comprises different colours insulating barrier core, it is characterized in that the core insulating barrier by homochromy insulating barrier with outer thin dichroic layer is compound forms.

2,, it is characterized in that said insulating barrier and thin dichroic layer are that co-extrusion fits tightly according to the described color separation cable of claim 1.
