Description
Technical Field
The invention relates to the technical field of wired and cable production, in particular to a high-life three-layer co-extrusion high-grade home decoration line and a production method thereof.
Background
The house ornamentation line is the wire and cable that contacts most in the resident life process, the house ornamentation line quantity is great, the customer is scattered, the quality is uneven, manufacturing enterprise is numerous, the house ornamentation line generally divide into hard wire and patchcord, along with the promotion of installation requirement, the increasing market of patchcord, current patchcord only adopts one deck polyvinyl chloride as the oversheath mostly, such oversheath is owing to there is great puncture risk and lower ageing-resistant performance, this type of product is more and more not accepted in the market.
Disclosure of Invention
The invention aims to provide a high-life three-layer co-extrusion high-grade home decoration line and a production method thereof.
In order to achieve the purpose, the invention adopts the technical scheme that:
a high-grade house ornamentation line of high-grade three-layer coextrusion of long-life and its preparation method, including the copper conductor, characterized by that: the copper conductor is externally provided with a crosslinked polyvinyl chloride layer, the crosslinked polyvinyl chloride layer is externally provided with a crosslinked polyethylene layer, the crosslinked polyethylene layer is externally provided with a polypropylene layer, and the copper conductor is externally formed at one time by adopting a three-layer co-extrusion technology.
As a further improvement of the invention, the copper conductor is formed by 32-core copper stranded wires.
As a further development of the invention, the polypropylene layer is colorless and transparent.
As a further improvement of the invention, the thickness of the crosslinked polyvinyl chloride layer is 0.2 mm, the thickness of the crosslinked polyethylene layer is 0.2 mm, and the thickness of the polypropylene layer is 0.3 mm.
The invention has the beneficial effects that the 32-core copper wires are stranded to form the soft copper conductor, the three-layer co-extrusion technology is adopted to extrude the insulating layer outside the copper conductor at one time so as to meet the adhesive property between two layers after cabling, the layering phenomenon does not occur after extrusion, the outermost layer of the home decoration wire is made of colorless and transparent polypropylene, the wear resistance is strong, the outer surface of the polypropylene is smooth, the outer surface of the home decoration wire can be effectively prevented from being scratched in the wiring process, and the innermost layer of the home decoration wire is made of crosslinked polyvinyl chloride and has strong flame-retardant and fire-resistant properties.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.
A high-grade house ornamentation line of high-grade three-layer coextrusion of life and its preparation method, including copper conductor 1, characterized by that: copper conductor 1 outside is provided with crosslinked polyvinyl chloride layer 2, crosslinked polyvinyl chloride layer 2 outside is provided with crosslinked polyethylene layer 3, crosslinked polyethylene layer 3 outside is provided with polypropylene layer 4, 1 outside adoption three-layer coextrusion technique is to cable one shot forming at copper conductor, carry out the stranded conductor through the copper wire and make into mild copper conductor 1, then adopt three-layer coextrusion technique once to extrude the insulating layer of 1 outside of copper conductor, with the glutinous stickness ability that satisfies behind the stranding between two-layer, the layering phenomenon does not appear after extruding, the outmost polypropylene preparation that adopts of house ornamentation line, has stronger wear resistance, and the polypropylene surface is more smooth, walk the line in-process like this and effectually prevent that house ornamentation line surface is scraped the flower, house ornamentation line inlayer adopts crosslinked polyvinyl chloride preparation, has stronger fire behaviour.
As a further preferable scheme of the invention, the copper conductor 1 is formed by 32-core copper wire stranded wires, the 32-core copper wires have stronger flexibility and lower heating value when electrified, and the copper wires are arranged more closely.
In a further preferred embodiment of the present invention, the polypropylene layer 4 is colorless and transparent, and the colorless and transparent polypropylene layer 4 can be visually recognized by observing the crosslinked polyethylene layer 3 after extrusion, so that the condition of the crosslinked polyethylene layer 3 can be relatively intuitively recognized.
As a further improvement of the invention, the thickness of the crosslinked polyvinyl chloride layer 2 is 0.2 mm, the thickness of the crosslinked polyethylene layer 3 is 0.2 mm, the thickness of the polypropylene layer 4 is 0.3 mm, the crosslinked polyvinyl chloride layer 2 and the crosslinked polyethylene layer 3 have the same thickness, the heat transfer and the heat conduction between the crosslinked polyvinyl chloride layer 2 and the crosslinked polyethylene layer 3 are more uniform and stable, the crosslinked polyvinyl chloride layer and the crosslinked polyethylene layer are more firmly adhered, and the polypropylene layer 4 with the thickness of 0.3 mm can ensure that the outer surface of the home decoration line is smooth.
