Definitions

  • the present invention relates to a lubricant composition for use in working electrically conductive substances such as power transmission cables, leads or wires used in electronic parts, coiling wires and the like, and a method for manufacturing such electrically conductive substances with the lubricant composition.
  • Linear metallic substances for use in power transmission cables, leads in electronic parts and the like, and in electrically conductive composite wires or cables consisting of a metallic core cladded with non-ferrous metals such as copper, aluminum and the like have been manufactured by producing linear metallic materials by any of known methods, for example, hot or warm extrusion, or hot rolling and reducing the diameter of the materials with a drawing bench having a die for working to produce linear substances having a desired diameter.
  • electrically conductive wires of a given dimension have been manufactured by means of a continuous drawing equipment having a plurality of benches bearing dies disposed on line.
  • the ratio in cross sectional area of the core to the cladding layer changes with the drawings of the wires, because the resistance to deformation of the core is different from that of the cladding. Therefore, the change of the ratio in cross-­sectional area of the core to the cladding due to drawing is predetermined, thereby the thickness of the cladding layer relative to the core is determined, based on which the composite substances are made and then drawn to give composite wires having desired dimensions.
  • the working such as the drawing described above has been carried out generally with lubricants of liquid- and/or powder-types as lubricants for working.
  • the velocity of transferring a wire must be higher in the later drawing step through which the wire passes.
  • the velocity may become as high as 250 to 400 m /min.
  • the surface condition of composite wires is dependent upon the ratio in cross-sectional area of the core to the cladding layer, the configuration of drawing dies, the percentage reduction, particularly to a great extent upon the lubricants. Furthermore, there is a need for increasing the speed of working to produce composite wires at a higher productivity, and for the purpose, the quality of lubricants must be improved to a great extent.
  • a lubricant having a higher viscosity is more effective to prevent metal materials from contacting with one another and the wires from galling during drawing.
  • Liquid lubricants include formulations consisting of a basic oil selected from mineral oils, synthetic oils such as ester oils and the like, and mixtures thereof, with addition of any of various additives such as oiliness improving agents, for example, higher fatty acids and higher alcohols as described by T. SAKURAI in “ PETROCHEMICAL ADDITIVES” ( published by Saiwai Shobo, Japan, May 1973 ) and extreme-­pressure lubricants of a phosphorus, chlorine or sulfur type.
  • a basic oil selected from mineral oils, synthetic oils such as ester oils and the like, and mixtures thereof, with addition of any of various additives such as oiliness improving agents, for example, higher fatty acids and higher alcohols as described by T. SAKURAI in “ PETROCHEMICAL ADDITIVES” ( published by Saiwai Shobo, Japan, May 1973 ) and extreme-­pressure lubricants of a phosphorus, chlorine or sulfur type.
  • Powder-type lubricants include metallic soaps such as calcium soap and sodium soap.
  • the soap powder is forced into a space between a die and a wire under pressure and then the drawing is effected.
  • a lubricant produced by incorporating metallic soap powder of 100 ⁇ m or less into polybutene [ see, Japanese Patent KOKAI (Laid-Open) No. Sho 55-135198 ].
  • lubricants for use in metal wire drawing produced by incorporating paraffin wax, chlorinated paraffine and phosphite ester or phosphate ester [see, Japanese Patent KOKAI (Laid-Open) No. Sho 62-153396] and those produced by dispersing fats and fatty oils or wax in water with a high molecular dispersant, surfactant and the like [ see, Japanese Patent KOKAI (Laid-­Open) No. Sho 55-147593 ].
  • the high viscosity lubricants as described above suffer from being reluctant and unmanageable in replenishing and the like, and when they are splashed around adhering to the surfaces of machinery and floor, their high viscosity may cause sticking of work clothings and shoes of operators on the splashed spots. In such case, there may be a risk that the operators fall down or be caught in the drawing machine to raise the problem of safty practice.
  • lubricants suitable for drawing steel wires are unsuitable for drawing non-ferrous metals, particularly soft metals such as copper or aluminum and apt to cause galling and surface cracking.
  • the surface cracking occurs when the non-ferrous metal materials has a higher shearing strength than the frictional force between the materials and the die.
  • lubricants for use in plastic working of aluminum one may employ polybutene having a viscosity of 0.171 m2/s (171,000 cSt)(40°C) or more. As described above, however, the lubricants have a less tendency to cause seizing of materials and dies making it possible to draw wires even at a velocity of 200 m /min, though the higher viscosity lubricants raise difficulties in workability and safty as pointed out above.
  • a lubricant composition comprising a base oil such as liquid high molecular compounds having a viscosity of 0.0003 to 0.05 m2/s (300 to 50,000 cSt) (at 40 °C) and an additive selected from a group consisting of animal and vegetable oils and aliphatic dicarboxylic acids.

  • a method for manufacturing electrically conductive substances characterized by coating the surface of a non-­ferrous metal material with a lubricant composition comprising a base oil of a liquid high molecular compound and an oiliness agent and plastically working the non-ferrous metal material with a die while forming a lubricant film on the surface of the material.

  • the thinner wire may further drawn sequentially by a desired number of wire drawing machines (the last one is designated as No.n ) to have a desired diameter.
  • the wire is introduced into treating chamber 9, passed through straightening machine 10 where the strain is removed, thereafter the lubricant adhered on the surface of the wire is removed by rolling brush 12 with solvent 11 and then the wire is dried.
  • the dried wire is wound on winding dram 15 of winding machine 14.
  • the lubricant comprises a base oil and an additive.
  • a base oil one may mention mineral oil.
  • mineral oil has a viscosity index not higher than 100 and its viscosity is rapidly reduced with an increase of temperature. For the reason, adhesion force of mineral oil to the surface of wire materials is lowered rendering lubrication poor, so that galling and fracturing of the wires are apt to occur and smooth drawing is unattainable.
  • the temperature of the drawing die is 120 °C or higher, the use of mineral oils as base oil leads to discoloration of the surface of the wires and is unsuitable for the high velocity drawing.
  • liquid high molecular compounds do not diminish the excellent lubricating properties of animal and vegetable fats and oils or aliphatic dicarboxylic acid as additives, have less tendency to lower the viscosity with an increase of the temperature and have excellent adherability and heat resistance.
  • the present invention has been made on the basis of this finding.
  • Liquid high molecular compounds include, for example, polybutene, polymethacrylate, polyisobutylene, ethylene- ⁇ -olefin copolymers.
  • polyphenol ether, fluorinated ester, polyether, and the like may be employed.
  • the liquid high molecular compounds are liquid polymers which can be produced by any of known methods, and their viscosity can be freely controlled by varying their molecular weight or selecting and incorporating those having different molecular weights.
  • the liquid high molecular compounds to be used as base oils should preferably have a viscosity of 300 to 50,000 cSt at 40 °C in view of the conditions of drawing, workability and manageability.
  • Additives (lubricity improving agents) to be incorporated into the base oils include animal and vegetable oils such as hardened castor oil, lard oil, linseed oil, soybean oil, hardened tallow, lanolin and the like.
  • Aliphatic dicarboxylic acids include those having 5 to 36 carbon atoms such as glutaric acid, adipic acid, pimelic acid, azelaic acid, sebacic acid, undecanoic acid, dodecanoic acid, tridecanoic acid, dimer acid and the like.
  • An amount of animal and vegetable fats and oils or aliphatic dicarboxylic acids to be incorporated into the base oil, liquid high molecular compound is 2 to 25 % by weight, preferably 5 to 20 % by weight. It an amount of animal and vegetable fats and oils or aliphatic dicarboxylic acids to be incorporated is less than 2 % by weight, the effect of improving lubricity is insufficient and galling is apt to occur during drawing. Although one may use a higher amount than 25 % by weight of the additives, any further improvement of antigalling will not be attained.
  • an oiliness improving agent such as higher fatty acids, higher alcohol and the like, an extreme-pressure lubricant of phosphorus-, chlorine- or sulfur-type, or metal soap powder and the like, if necessary.
  • an oiliness improving agent such as higher fatty acids, higher alcohol and the like, an extreme-pressure lubricant of phosphorus-, chlorine- or sulfur-type, or metal soap powder and the like, if necessary.
  • water so as to produce the lubricants of emulsion type.
  • any of known emulsifiers may be added.
  • the present invention allows composite wires consisting of superconductive core material cladded with non-­ferrous metal material such as copper, aluminum and the like to be drawn at a higher velocity.
  • the lubricants used in the present invention exhibit a lower reduction of viscosity with an increase of the temperature and are thermally stable and excellent in adhesion to the surface of metal material with formation of a good lubricant film (oil film) at the frictional interface upon plastic working.
  • a good lubricant film oil film
  • the film produced by the reaction of the surface of non-ferrous metal material and the additive in the lubricant, i.e., animal and vegetable fats and oils or aliphatic dicarboxylic acid is formed on the surface subjected to plastic working resulting in prevention of galling and in facility of plastic working because the film has an excellent lubricating property.
  • the film is a metal soap film produced by primarily the reaction of the surface of the non-ferrous metal material and the additive with frictional heat generated at the interface between the material and the die; see, T.SAKURAI, "LUBRICANT OIL ADDITIVES - STATE AND FUTURE", LUBLICATION, 15 , No.6302-310, (1970).
  • the metal soap film is effectively formed locally at a part of the surface of the material in contact with the die to become a stiff film preventing the "galling" which occurs owing to direct contact of the metal material with the die. Therefore, smooth plastic working can be achieved. Such effect can be most remarkably attained in wire drawing with no galling occurring even in high velocity wire drawing.
