Description
Technical field
The present invention relates to a kind of production method of cable, especially a kind of production method of microwave vulcanization rubber-sheathed cable.
Background technology
Plastic-sheathed Cable product, which needs to cover outer layer rubber, carries out vulcanizing treatment, and raw rubber is linear molecule, similar plasticine,
Rubber molecule becomes three-dimensional cross-linked structure from straight line connection after over cure, to make it have insulation, high resiliency, high resistance to
Mill, it is anticorrosive, the advantages that.Plastic-sheathed Cable generally uses steam under pressure sulfuration process, due to the poor thermal conductivity of rubber, in raw rubber
The outer temperature difference is larger, to complete inside and outside whole vulcanization, by steam under pressure long duration of action, impressed pressure can be such that thermal energy passes as early as possible
Be delivered to inside raw rubber, while ensureing the smooth of rubber epidermis, thus traditional steam Plastic-sheathed Cable vulcanization time length, high energy consumption,
Efficiency is low, of high cost.
A kind of methods of new rubber wire cable vulcanization of patent CN104416699 propose 1, from extruder for shaping
Cable is drawn by pulling force, and into microwave vulcanization device, cable is brought rapidly up curing temperature by microwave here；2, then
Treated cable is put into the hot wind slot of post-cure, time and temperature will be set in hot wind slot, then cable is in warm
It is acted in wind groove；3, cable cooling device is put into after acting in hot wind slot to cool down；4, the cooling cable of recycling.
The production method of 200710169115.3 microwave vulcanization rubber-sheathed cable of patent proposes conductor is equal by pay off rack
Even steady releasing squeezes out the rubber set of cable by extruder, and the cable for having coated rubber set is utilized microwave heating to 130-160 degree
Vulcanized, keeps the curing temperature hot wind vulcanizing equipment heap cable of 130-160 degree to continue to vulcanize, room temperature is cold after the completion of vulcanization
But, it crosses take-up reel and obtains microwave vulcanization rubber-sheathed cable, the object that cures is monitored by infrared temperature control instrument, prevents over cure.
Above-mentioned two patents all use common adhesive tape microwave vulcanization technology, practical application can there is a problem of it is bigger,
1, the general diameter specifications of cable are more, and epidermis cannot have stomata, bubble, microwave heat effect rubber under no pressure protection after vulcanization
Glue can make its foaming, and this is fatal defect to cable；And two patents refer to be rapidly heated, rubber all has ignored cable
Surface it is anti-foaming, stomata quality control method, that is, pressurization；2, microwave is in heat rubber and subsequent heat preservation vulcanizes
When, it is required for hot steam and pressurization hot wind protection, to reach accelerated surface skinning；3, due to the poor thermal conductivity of rubber set, microwave sulphur
When change, steam, hot wind actual temperature will be far above curing temperature；Two patents all do not account for this problem.So
It can not be applied successfully in commercial Application.
Invention content
A kind of production method of microwave vulcanization rubber-sheathed cable of the present invention is with microwave combination conventional vapor or pressurization hot wind
Overcome that existing vapor sulfurizing process energy consumption is big, the technologies such as blibbing, stomata existing for of poor quality and existing microwave vulcanization technique
Defect.
Technical problems to be solved needed for the present invention, are achieved through the following technical solutions：It is characterised in that it includes as follows
Step：
1, plain conductor is released by pay off rack uniform and stable, the rubber set of cable is squeezed out by extruder；
2, the cable for having coated rubber set is fast by microwave by steam or the microwave heating pipeline for the hot wind that pressurizes, Plastic-sheathed Cable
Speed is heated to 100-170 DEG C, has 100-250 DEG C of steam or 200-500 DEG C of pressurization hot wind in pipeline, and pressure is in 3-12MPa；
3 then in back segment 100-250 DEG C of steam or 200-500 DEG C of pressurization hot air duct heat preservation complete to vulcanize, pressure
It is maintained in 3-12MPa；
4, conventional chilling after vulcanizing obtains into disk by take-up reel and vulcanizes Plastic-sheathed Cable.
Wherein in step (1), the rubber set of cable refers to various natural rubbers, ethylene-propylene diene copolymer and various epoxy glues or replaces
For the general name of glue product.
Wherein in step (2), microwave is the microwave frequency band that International Power committee (ISM) divides, and industrial use generally uses
915MHz or 2450MHz, the microwave as 915MHz frequencies will be used when rubber set is thicker；
Wherein in step (2), when microwave heating, Plastic-sheathed Cable is in the curing tube of the steam of pressurization or the hot wind that pressurizes
It is interior；
Wherein in step (2), Plastic-sheathed Cable is under microwave heating and steam or pressurization hot wind immixture, steam
The microwave heating pipeline pressure of heating or pressurization hot wind is 3-12MPa, S00 DEG C of high temperature resistant, the metallic conduit for not leaking microwave；
Further, which can also be the pressure-resistant 3- being integrated with follow-up steam vulcanization or the hot air duct that pressurizes
The metallic conduit of 12MPa, 500 DEG C of high temperature resistant.
Wherein in step (2), when microwave heating, Plastic-sheathed Cable is in the steam or pressurization hot wind curing tube of pressurization,
The temperature of steam is controlled at 100-200 DEG C at this time, and pressure is in 3-12MPa；When using hot wind, temperature is controlled at 200-500 DEG C, pressure
Power does not have blistering, stomata problem in 3-12MPa to ensure that gum cover cable surface skinning is smooth.
