Abstract
The utility model relates to a polyether ether ketone (PEEK)-coated copper flat wire, which is mainly characterized in that a layer of PEEK is coated at the periphery of the copper flat wire. According to the utility model, an oxygen-free copper rod made by an up-draw process is made into a copper flat wire by an extrusion method, and then PEEK is coated on the copper flat wire through an extruder. As PEEK has the characteristics of good high-temperature (350-400 DEG) fluidity and high thermal decomposition temperature (560 DEG), the PEEK-coated copper flat wire can still maintain good insulating ability and high performance ability when the r irradiation dose reaches 110Mrad. The PEEK-coated copper flat wire is an electromagnetic wire or a cable with high strength, high heat resistance, high insulation, high radiation resistance and other high performances.
Description
Technical field
The utility model relates to a kind of electromagnetic wire or cable, particularly a kind of polyether-ether-ketone coated copper lenticular wire.
Background technology
Polyether-ether-ketone (PEEK) is a kind of high-performance special engineering plastics of crystallization shape, have the performances such as extremely good comprehensive physical, machinery, electricity, heat, chemistry, can with traditional thermoplastic plastics shaping processing method as inject, extrude, mold pressing, powder coating, machine cut etc. make various product, be subject to sample design teacher, processing and forming enterprise, product manufacturing supplier's extensive concern and attention, thereby obtain a wide range of applications in fields such as petrochemical industry, communications and transportation, electric, health care, food processing, universe aviations.The degree of freedom that it shows in design, the quality stability that the economic benefit that produces when processing and forming and product in use demonstrate makes it to become the successful succession of many common materials.
PEEK contains the high polymer that the repetitive of a ketonic bond and two ehter bonds consists of in backbone structure, belong to the speciality polymer material.Have the physical and chemical performances such as high temperature resistant, chemical resistance corrosion, it is a class crystalline polymers material, 334 ℃ of fusing points, 168 ℃ of softening points, hot strength 132～148MPa, can be used as high-temperature-resistant structure material and electrical insulating material, can with glass fibre or the compound preparation reinforcing material of carbon fiber, the general employing with the condensation of aromatic dicarboxylic phenol and a class polyarylether class high polymer.Most domestic manufacturing enterprise utilizes this type of performance of PEEK, with PEEK extensive use in these type of productions such as aerospace field, auto manufacturing, industry, medicine equipment manufacturing (can adopt PEEK to replace the metal-made body bone that makes children) and semi-conductor industry.Up to the present China also none enterprise the PEEK polymer is used for the production of electromagnetic wire, cable.
Summary of the invention
The purpose of this utility model is to provide the polyether-ether-ketone coated copper lenticular wire of a kind of PEEK of having high strength, high heat-resisting, high insulation, the contour performance of radiation hardness.
The technical solution of the utility model is: a kind of polyether-ether-ketone coated copper lenticular wire, consisted of by copper strap wire and polyether-ether-ketone, and it is characterized in that: the periphery at copper strap wire coats one deck polyether-ether-ketone.
The copper strap wire that the oxygen-free copper bar that described copper strap wire adopts up-drawing method to produce is produced by extrusion, its copper content is more than 99.95%, below the oxygen content 20ppm.
Described polyether-ether-ketone is coated on it on copper strap wire by extruder.
Polyether-ether-ketone coated copper lenticular wire described in the utility model is a kind of novel winding material, and its properties is all extremely good.The oxygen-free copper bar that copper strap wire adopts up-drawing method to produce, its copper content is more than 99.95%, below the oxygen content 20ppm, pole stock surface-brightening, cleaning, there is not greasy dirt, produce the copper strap wire of any surface finish, function admirable through advanced person's extrusion production line, and then by extruder polyether-ether-ketone is coated on the copper strap wire.Main rapidoprint polyether-ether-ketone (PEEK) resin that polyether-ether-ketone is coated on copper strap wire is a kind of new special engineering plastics.Have the characteristic that can be equal to mutually with polyimides, be called as super thermal endurance thermoplastic resin.Has following characteristic of having very much a glamour;
(1) short-term heat resistance: its heat distortion temperature can reach more than 300 ℃ after glass fibre or carbon fiber strengthened.
(2) long-term heat resistance: Undterwriter's Laboratory temperature index (RTI) is 250 ℃.
(3) toughness: be a kind of very pliable and tough resin.
(4) anti-flammability: reach UL94V-0 level (1.5mm), self-extinguishment is arranged, the amount of being fuming is minimum in all resins during burning.
(5) corrosion resistance/resistance to chemical reagents: solvent-freely except the concentrated sulfuric acid can corrode it.
(6) hot water resistance (can in 200～300 ℃ of steam, use).
(7) endurance and creep resistant (are the highest in the thermoplastics;
(8) processing forming: except injection moldable, applicable various forming method also
Because it has the characteristics of high temperature (350～400 ℃) good fluidity and heat decomposition temperature very high (560 ℃) PEEK, so polyether-ether-ketone coated copper lenticular wire still can keep good insulating capacity and high-performance ability when the r irradiation dose reaches 110Mrad.
Polyether-ether-ketone coated copper lenticular wire reaches 250 ℃ according to the hot index of long-term anti-height of raw material material PEEK, the short-term heat resistance temperature can reach more than 300 ℃, the performance of insulation resistance is high simultaneously, insulation thickness is 50 microns, disruptive field intensity is at 190KV/mm, the amount of being fuming corrosive gas low and that produce is few during burning, it is good to have anti-fissility, abrasion performance is good, every advantages such as radioresistance is strong, exactly because PEEK has so high-strength performance, this type of electromagnetic wire, the high property of cable insulating material copper strap wire is applied usually in nuclear reactor, the military field of the environment harshnesses such as warship.
