Abstract
The invention discloses a kind of rubber cable conductor non-oxidation production method, comprise the following steps: in (1) elastomeric material formula system, adopt the agent of VA-7 vulcanization crosslinking; (2) conductor adopts oxygen-free copper-wire, adopts antioxidant M and antioxidant MB to make antioxygen separator during conductor bundle strand; (3) drag bag electricity every paper when extruding, electricity squeezes into elastomeric material again every the parcel conductor that paper is complete.The invention solves the phenomenon that the rubber cover electric wire bare copper conductors such as natural rubber, acrylonitrile-butadiene rubber and butadiene-styrene rubber are oxidized after curing, turn black; Reduce oxidization condition in production process, can increase the service life; Isolation elastomeric material directly contacts with copper cash, also protects age resistor to be destroyed because of high temperature during sulfuration simultaneously.
Description
Technical field
The present invention relates to a kind of rubber cable conductor production method, specifically a kind of rubber cable conductor non-oxidation production method.
Background technology
Now commercially all rubber wire cables due to steam high temperature during sulfuration make conductor in process of production more or less create oxidation, thus cause conductor have send out crow, blackout a phenomenon, cause be greatly affected the useful life of product.Generally in the formula system of natural rubber and butadiene-styrene rubber, use sulphur as vulcanizing agent, when using sulphurous materials as promoter, free sulphur can be produced when saturated steam is high temperature vulcanized, conductor is very easily oxidized, this namely ordinary rubber electric wire to produce after after stripping insulation layer generation can find that conductor has the basic reason of obfuscation, blue oxidization condition of even turning black.Adopted the vulcanization accelerator of TMTD i.e. thiuram afterwards, although make moderate progress, could not from addressing this problem at all.
Summary of the invention
The object of the present invention is to provide a kind of rubber cable conductor non-oxidation production method, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of rubber cable conductor non-oxidation production method, comprises the following steps:
(1) adopt the agent of VA-7 vulcanization crosslinking in elastomeric material formula system, in this material, sulphur is saturated sulphur, at high temperature can not produce free sulphur;
(2) conductor adopts oxygen-free copper-wire, antioxidant M and antioxidant MB is adopted to be dissolved in alcohol during conductor bundle strand, conductive surface is adhered in liquid being convenient to, by conductor by drenching the wool felt having antioxidant alcohol, the beneath copper plate of wool felt is heated by low-voltage, high-current, after alcohol and moisture content volatilization, conductive surface can adhere to one deck antioxygen separator, isolated with rubber compounding in the composition that decomposites react and the oxidation that causes, thus fundamentally improving oxidative phenomena;
(3) drag bag electricity every paper when extruding; when insulation extrusion; conductor adopts cable barrier paper to drag bag to extrude; electricity squeezes into elastomeric material again every the parcel conductor that paper is complete; many one deck antioxygen separators, make being not easy to directly act on conductor containing high temperature when air and sulfuration thus destroying original protective layer in conductor in addition.
As the further scheme of the present invention: described conductor adopts the naked round copper stranded conductor of 85/0.19mm electrician.
As the present invention's further scheme: the M of antioxidant described in step 2 and antioxidant MB are after alcohol dissolves, load in alcoholic solution bottle, permeate on wool felt after dripping volume control device and controlling, after copper wire enters wool felt, remove alcohol and moisture content through copper plate heat block heating volatilization.
Compared with prior art, the invention has the beneficial effects as follows: the purification improving crosslinking agent in formula system, control sulfur molecule produce free after high temperature and long-time use thus cause being oxidized with copper wire, solve the phenomenon that the rubber cover electric wire bare copper conductors such as natural rubber, acrylonitrile-butadiene rubber and butadiene-styrene rubber are oxidized after curing, turn black; Age resistor and antioxidant are dissolved in alcohol, then the method for heating volatilization alcohol is coated with last layer age resistor and antioxidant on the surface of copper free wire, not only reduces oxidization condition in production process, more can increase the service life; Conductive surface drags bag paper tape, turn increases one deck protection, and isolation elastomeric material directly contacts with copper cash, also protects age resistor to be destroyed because of high temperature during sulfuration simultaneously.
Accompanying drawing explanation
Fig. 1 is age resistor Dropping feeder schematic diagram in rubber cable conductor non-oxidation production method;
Fig. 2 is the sectional view of rubber cable conductor.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-2, a kind of rubber cable conductor non-oxidation production method, conductor 7 adopts the naked round copper stranded conductor of 85/0.19mm electrician, through the anti-old process of antioxygen during bundle strand, by pulverous antioxidant M and antioxidant MB after alcohol dissolves, load in alcoholic solution bottle 1, permeate on wool felt 3 after dripping volume control device 2 and controlling, heat volatilization through copper plate heat block 4 after copper wire 6 enters wool felt 3 and remove alcohol and moisture content, one deck antioxygen separator can be adhered in alcohol and rear conductor 7 surface of moisture content volatilization, the oxidation that the composition completely cut off and decomposite in rubber compounding reacts and causes, thus fundamentally improving oxidative phenomena, drag bag electricity every paper 8 during extruded insulation, electricity squeezes into elastomeric material layer 9 again every the parcel conductor 7 that paper 8 is complete, nominal thickness is 1.0mm, nominal diameter is 4.20mm, insulated wire crosses talcum powder, three core insulation line twisted synthesizing cables, the agent of VA-7 vulcanization crosslinking is adopted in the elastomeric material formula system of elastomeric material layer 9, in this material, sulphur is saturated sulphur, at high temperature free sulphur can not be produced, coordinate the use of antioxidant MB and DNP, greatly reduce the situation of conductor indium, skin arranges sheath 10 and protects, the nominal thickness of sheath 10 is 1.2mm, nominal diameter is 11.4mm.Electricity squeezes into elastomeric material again every the parcel conductor that paper 8 is complete, and on the one hand many again one deck antioxygen separators, make being not easy to directly act on conductor containing high temperature when air and sulfuration thus destroying original protective layer in conductor in addition.
Present invention improves the purification of crosslinking agent in formula system, control sulfur molecule and produce free after high temperature and long-time use thus cause being oxidized with copper wire.Age resistor is dissolved in alcohol, then the method for heating volatilization alcohol is coated with last layer age resistor on the surface of copper free wire, not only reduces oxidization condition in production process, more can increase the service life.Conductive surface drags bag paper tape, turn increases one deck protection, and isolation elastomeric material directly contacts with copper cash, also protects age resistor to be destroyed because of high temperature during sulfuration simultaneously.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned execution mode, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
