Abstract
The invention discloses a kind of low smoke and zero halogen nanometer fireproof electric wire, it includes cable core, fireprotection layer and insulating layer.Cable core is enclosed with fireprotection layer and insulating layer successively from inside to outside.The present invention low smoke and zero halogen nanometer fireproof electric wire there is good fire protecting performance, can under 950 1000 DEG C of flame conditions, burn 3 it is small when, while spray, vibration under conditions of guarantee circuit integrality and circuit it is unimpeded.
Description
Technical field
The present invention relates to electric wire field, more particularly to a kind of house ornamentation environmental-protection low-smoke halogen-free nanometer fireproof electric wire.
Background technology
In recent years, continuous improvement and national further carrying to fire-fighting safety standard with the awareness of safety of people
Rise, existing fireproof electric wire cannot meet existing design and standard requirement, and conventional fire resisting flame-proof wire twines for mica tape
Around structure, multi-lay winding is wanted in process of production, since process conditions limit, overlap joint defect easily occurs, plus cloud after baked wheaten cake
The easy embrittlement of master tape, come off, and largely reduces flameproof effect, causes line short.How a kind of flameproof effect is invented
More cable and wire has become industry urgent problem to be solved.
The information for being disclosed in the background section is merely intended to understanding of the increase to the general background of the present invention, without answering
It has been the prior art well known to persons skilled in the art when being considered as recognizing or implying the information structure in any form.
The content of the invention
It is an object of the invention to provide a kind of low smoke and zero halogen nanometer fireproof electric wire, it, can with good fire protecting performance
With under 950-1000 DEG C of flame conditions, when burning 3 is small, while ensure under conditions of spray, vibration the integrality of circuit
It is unimpeded with circuit.
To achieve the above object, the present invention provides a kind of low smoke and zero halogen nanometer fireproof electric wire, it includes cable core, fire prevention
Layer and insulating layer.Cable core is enclosed with fireprotection layer and insulating layer successively from inside to outside.
Preferably, in above-mentioned technical proposal, cable core is the conducting wire that one or more metal is twisted.
Preferably, in above-mentioned technical proposal, fireprotection layer extrudes composition for low smoke and zero halogen nano ceramics chemoprevention fire polyolefin.
Preferably, in above-mentioned technical proposal, insulating layer extrudes composition for halogen free nanometer fire retardant polyolefin.
Compared with prior art, low smoke and zero halogen nanometer fireproof electric wire of the invention has good fire protecting performance, Ke Yi
Under 950-1000 DEG C of flame conditions, burning 3 it is small when, while spray, vibration under conditions of ensure circuit integrality and line
Road it is unimpeded.And causing electric wire that integrally there is stronger fire protecting performance, safety coefficient is high, significantly reduces because fire is brought
Unnecessary loss.
Brief description of the drawings
Fig. 1 is the sectional view of low smoke and zero halogen nanometer fireproof electric wire according to the present invention.
Main Reference Numerals explanation：
1- cables core, 2- fireprotection layers, 3- insulating layers.
Embodiment
Below in conjunction with the accompanying drawings, the embodiment of the present invention is described in detail, it is to be understood that the guarantor of the present invention
Protect scope and from the limitation of embodiment.
Explicitly indicated that unless otherwise other, otherwise in entire disclosure and claims, term " comprising " or its change
Change such as "comprising" or " including " etc. and will be understood to comprise stated element or part, and do not exclude other members
Part or other parts.
As shown in Figure 1, Fig. 1 is the sectional view of low smoke and zero halogen nanometer fireproof electric wire according to the present invention.Have according to the present invention
A kind of low smoke and zero halogen nanometer fireproof electric wire of body embodiment, including cable core 1, fireprotection layer 2 and insulating layer 3.Cable core 1 is
The conducting wire that one or more metal is twisted；Fireprotection layer 2 is wrapped in the outside of cable core 1, and fireprotection layer 2 is low smoke and zero halogen nano ceramics
Chemoprevention fire polyolefin (mineral insulation material) extrudes composition；Insulating layer 3 is wrapped in the outside of fireprotection layer 2, and insulating layer 3 is received for Halogen
Rice fire retardant polyolefin extrudes composition.
In conclusion the low smoke and zero halogen nanometer fireproof electric wire of the present invention is compared with prior art, there is good fire line
Can, can be under 950-1000 DEG C of flame conditions, when burning 3 is small, while ensure the complete of circuit under conditions of spray, vibration
Whole property and circuit it is unimpeded the advantages that.And causing electric wire that integrally there is stronger fire protecting performance, safety coefficient is high, greatly reduces
Because of unnecessary loss caused by fire.
It is foregoing to the present invention specific exemplary embodiment description be in order to illustrate and illustration purpose.These descriptions
It is not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to the above instruction, can be much changed
And change.The purpose of selecting and describing the exemplary embodiment is that explain that the certain principles of the present invention and its reality should
With so that those skilled in the art can realize and utilize the present invention a variety of exemplaries and
Various chooses and changes.The scope of the present invention is intended to be limited by claims and its equivalents.
