Abstract
The invention relates to a lubricant for drawing of nickel and nickel-alloy wires, rods and tubes. According to the lubricant, 68# full-loss system oil is adopted as base oil and is matched with a variety of compound additives, including an oily agent, an anti-wear agent, an extreme pressure agent, an antifoamer, an antioxidant, a reinforcer and auxiliaries. According to the lubricant for drawing of nickel and nickel-alloy wires, rods and tubes, disclosed by the invention, the lubricating property is good, the strength of an oil film in a deformation zone can be enhanced, the coefficient of friction is lowered, and the composition and performance are stable; the permeability is relatively strong, the diffusion is easy, and the wear resistance, the viscosity-temperature characteristics and the flushing performance are good; the extreme pressure characteristic is strong, and the cooling and lubricating properties are good, so that contact faces between a material and a mold are indirectly close to a fluid lubrication state, then, the shear stress resulting from friction is lowered, the wear to drawing tools and drawing dies is reduced, the flowing shear stress is relatively small, and the surface smoothness and specification accuracy of metal are improved.
Description
Technical field
The invention belongs to the lubricant of non-ferrous metals processing drawing lubricant, particularly drawing Ni-based ultrafine powder line, rod, tubing.
Background technology
Nickel, silvery white metal, fusing point 1455 DEG C, boiling point 2730 DEG C, density is 8.902g/cm
3.Nickel has good physical strength and ductility, infusibility, and matter is hard, has magnetic and good plasticity-; The erosion resistance had, not oxidized in atmosphere, resistance to highly basic again.Nickel is the metal of a medium tenacity.Metallic nickel is mainly used in electroplating industry, the article of nickel plating are attractive in appearance, totally, not easily corrosion again.
Because nickel has good physical strength and ductility, infusibility is high temperature resistant, and there is very high chemical stability, the feature such as not to be oxidized in atmosphere, therefore be a kind of very important non-ferrous metal raw material, be used to manufacture stainless steel, High Nickel Steel and structural alloy steel, be widely used in the various military industrial manufacturing enterprises such as aircraft, radar, guided missile, tank, naval vessels, spaceship, reactor.In civilian industry, it is a large amount of for various machinery manufacturing industry that nickel often makes structure iron, duriron, high temperature steel etc.Nickel also can make beramic color and coating for protection against corrosion.Nickel cobalt (alloy) is a kind of permanent magnet material, is widely used in the fields such as electronic telecontrol, nuclear industry and ultrasonic technique.Nickel basic product has: nickel strap, nickel sheet, nickel plate, nickel rod, nickel bead, nickel foil, nickel dish, nickel bits, nickel electrode, sponge nickel, nickel goods, nickel rim charge, nickel angle nickel screen, electrolytic nickel, electroformed nickel, Foamed Nickel, pure nickel wire etc.
Drawing Ni-based ultrafine powder line, bar impose pulling force to the metal stock of Ni-based ultrafine powder, makes it by nib to obtain the plastic processing method with nib sectional dimension, goods that shape is identical.In drawing process, except material, friction between drawing-die and steel core, on the contact surface because drawing speed improves, will occurrence temperature sharply rise.There is heavy wear or sintering to reduce in drawing process, make to decline close to Liquid Lubrication Condition so that fricative shear-stress between the contact surface of material and mould, the effect thus requiring lubricant to play antifriction and prevent wearing and tearing, cool, lubricate; Be improved drawing speed and section reduction rate, to improve seed output and quality simultaneously.
Summary of the invention
It is good that the technical problem to be solved in the present invention is to provide a kind of lubricity, and oil film strength is high, and frictional coefficient is low, and composition and stable performance, have stronger perviousness, easily spread, and resistance to abrasion, sticky warm nature, flushing performance are good; Extreme pressure property is strong, Cooling and Lubricator is good, reduces the wearing and tearing of drawing device and drawing-die, improves the lubricant of the drawing Ni-based ultrafine powder line of metallic surface smooth finish and specification precision, rod, tubing.
The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 68 total loss system oil, coordinate multiple composite additive, its each component and mass percent are:
| Component | Content (mass percent) |
| Base oil | Surplus |
| Oiliness improver | 8.0%～12.0% |
| Anti-wear agent | 8.0%～10.0% |
| Extreme pressure agent | 3.0%～5.0% |
| Oxidation inhibitor | 0.8%～1.2% |
| Kilfoam | 0.005%～0.01% |
| Strengthening agent | 2.0%～3.0% |
| Auxiliary agent | 3.0%～5.0% |
Base oil is No. 68 total loss system oil.
Oiliness improver is sulfuration Oleum Gossypii semen.
Anti-wear agent is clorafin 42.
Extreme pressure agent is tritolyl phosphate.
Oxidation inhibitor is the N-phenyl-α-aniline of mass ratio 50% ~ 40% and the amino p-cresol compound of 2,6-di-t-butyls-alpha, alpha-dimethyl of 50% ~ 60%.
Kilfoam is dimethyl silicone oil.
Strengthening agent is lauric acid phosphoric acid ester.
Auxiliary agent is polyisobutene.
The lubricant of drawing Ni-based ultrafine powder line of the present invention, rod, tubing, has good lubricity, can increase oil film strength in distorted area, reduces frictional coefficient, composition and stable performance; Have stronger perviousness, easily spread, resistance to abrasion, sticky warm nature, flushing performance are good; Extreme pressure property is strong, Cooling and Lubricator is good, make to decline close to Liquid Lubrication Condition so that fricative shear-stress between the contact surface of material and mould, reduce the wearing and tearing of drawing device and drawing-die, have less flowing shear-stress, improve metallic surface smooth finish and specification precision.
