Technical field
The invention belongs to Aviation cable technical field, specifically a kind ofly novelly pull Aviation cable and preparation method thereof.
Background technology
At present, Aviation cable that market is applied adopts the composite electric wire of cross-linked ethylene-tetrafluoroethene or polyimides, for specification less need improve by alloy core the ability pulled.The shortcoming of above-mentioned composite cable is that the resistance to wear of cross-linked ethylene-tetrafluoroethene is bad; The wire of the composite electric wire of polyimides needs sintering, and technique is difficult to grasp, and these raw material are all controlled by abroad at present, particularly polyimides composite band; In addition it is also bad that above-mentioned composite cable anti-pulls performance.
Summary of the invention
In order to overcome existing aircraft wire cable, pull ability, poor performance, technique is difficult to grasp, the shortcoming that manufacturing cost is high, the invention provides that a kind of ability of pulling is strong and high temperature resistant, wear-resisting, the novel of hydrolysis pulls Aviation cable and preparation method thereof.
The technical solution used in the present invention is: one is novel pulls Aviation cable, comprise conductive core line, be coated on composite insulation layer on conductive core line successively from inside to outside, pull bearing layer and composite jacket layer, described composite insulation layer is made up of insulating barrier I and insulating barrier II, described restrictive coating is made up of restrictive coating III and restrictive coating IV, described insulating barrier I is coated on conductive core line, described restrictive coating III is coated on and pulls on bearing layer, described conductive core line adopts that silver-coated copper wire is stranded to be made, described in pull bearing layer and adopt pbo fiber to make.
Wherein, described insulating barrier I and restrictive coating III are made up of pure polyimide material, and described insulating barrier II and restrictive coating IV adopt ethylene-tetrafluoroethylene material to make.
One is novel pulls Aviation cable preparation method, comprises the steps:
A, make conductive core line with the stranded many silver-plated circular copper wires of pipe twisting machine;
B, carry out the braiding of pure polyamide tape insulating tape at conductive core line external application 16 ingot or 24 ingot bandlet braiding machines, make insulating barrier I;
C, extrude ethylene-tetrafluoroethylene at insulating barrier I external application single screw extrusion machine, extruder, with certain speed rotary screw, is equipped with hauling speed, makes insulating barrier II;
D, make insulating barrier after, the braiding carrying out PBO silk at external application wrapping machine is wound around, and forms one deck circle and pulls bearing layer;
E, make and pull bearing layer after, manufacture polyimides lapping layer respectively at the wrapped production line of the vertical double end of external application, make restrictive coating III;
F, outside restrictive coating III, extrude ethylene-tetrafluoroethylene with single screw extrusion machine, extruder, with certain speed rotary screw, is equipped with hauling speed, makes restrictive coating IV, finally obtained novelly pulls Aviation cable.
Advantage of the present invention is:
Apply polyamide tape and carry out internal layer braiding, utilize its hardness, use for reference the experience of coaxial cable bandlet braiding, realize this technique very soon, saving polyimides composite band needs the technique of sintering to grope, pure polyamide tape and the domestic manufacture of materials maturation of ethylene-tetrafluoroethylene, reach the object reduced costs.
The pbo fiber adopted, its intensity is high, material is lighter than silver-plated circular copper wire, can improve cable dragging ability, and the external force produced when preventing aircraft altitude from flying is broken.
The process materials procurement cycle that this Aviation cable uses is short, production efficiency is higher, this material has the features such as high temperature resistant, lightweight, external diameter is little, little, the vacuum loss superior performance of burning smoke density, mechanical strength is high, flame resistance good, radiation resistance is superior simultaneously, meet many requirements of aviation aircraft, be adapted to cabling requirement under the loss of weight and hot environment of aviation aircraft.
