Abstract
The invention discloses a lubricant composition for drawing a tantalum filament. According to the lubricant composition, MVI 400 base oil is used as base oil and is matched with a plurality of additives. The lubricant composition comprises an impregnating agent, a wetting enhancer, an oiliness agent, an anti-wear agent, an anti-foaming agent and an antioxidant. The lubricant composition can be directly applied to the lubricating process during the drawing of the tantalum filament and has relatively strong adhesion and good wear resistance, viscosity-temperature property, extreme pressure property, cooling property, cleaning performance, wettability, liquidity and lubricating property; a lubricating film is high in strength and thickness, the wear between a drawing tool and a draw mold can be reduced, the flow shear stress is relatively low, and the surface smoothness and standard precision of metal can be improved; the lubricant composition has certain chemical stability, and oil spots and surface defects of the filament can be reduced.
Description
Technical field
The invention belongs to metal working lubricant field, particularly a kind of tantalum fine drawing lubricant compositions.
Background technology
Tantalum can do that capacity is large, volume is little, the solid electrolytic capacitor of stable performance, for radar, guided missile, supersonic plane and robot calculator.Tantalum can also manufacture the groove of petrochemical complex heat exchanger, well heater, thickener and reactor, tower, pipeline and valve etc.Tantalum is also used as electron emission pipe and high-power tube part material.Tantalum alloy can make supersonic plane combustion chamber and heat-resisting resistance to Materials with High Strength, the guided missile nozzle of tantalum-tungsten alloy.Tantalum has very outstanding chemical property, has high erosion resistance.No matter be under cold or hot condition, hydrochloric acid, concentrated nitric acid and " chloroazotic acid " are not reacted.Can be used to manufacture evaporator boat etc., also can do the electrode of electron tube, rectifier, electrolysis, electric capacity.Medically be used for laminating or fine rule, sew and mend the tissue destroyed.
Drawing is one of main production process of tubing, bar, section bar and wire rod.By article section shape, drawing can be divided into solid material drawing and the large class of hollow material drawing two.Drawing tantalum filament imposes pulling force to tantalum blank, 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.Heavy wear or sintering is there is, the effect thus requiring lubricant to play antifriction and prevent wearing and tearing, cool, lubricate in order to reduce in drawing process; Be improved drawing speed and section reduction rate simultaneously, to improve the seed output and quality of drawing process processing, prevent the generation of the defect such as surface tear, fold, bending, bias, crackle, broken end, metal press-in, guarantee that the tantalum filament after drawing has best bright finish.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has stronger adhesivity, strength of lubricant film and thickness large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, cooling, cleaning, wetting property, mobility and oilness are good, can reduce the wearing and tearing of drawing device and drawing-die, have less flowing shear-stress, metallic surface smooth finish and specification precision can be improved, have certain chemical stability and reduce the tantalum fine drawing lubricant compositions occurring oil mark and filament surfaces defect.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
A kind of tantalum fine drawing lubricant compositions, adopt oil based on MVI 400 base oil, coordinate multiple additives, its each component and mass percent thereof are:
| Component | Mass percent content |
| Base oil | Surplus |
| Treating compound | 13％～20％ |
| Dibutyl phthalate | 17％～23％ |
| Oiliness improver | 6％～8％ |
| Anti-wear agent | 3％～5％ |
| Kilfoam | 10ppm～50ppm |
| Oxidation inhibitor | 0.3％～0.5％ |
Treating compound is ether.
Dibutyl phthalate is tetracol phenixin.
Oiliness improver is stearic acid.
Anti-wear agent is phosphoric acid ester.
Kilfoam is dimethyl silicone oil.
Oxidation inhibitor is 2,6-di-t-butyl mixed phenol.
Remarkable advantage of the present invention is: have stronger adhesivity, strength of lubricant film and thickness large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, cooling, cleaning, wetting property, mobility and oilness are good, can reduce the wearing and tearing of drawing device and drawing-die, have less flowing shear-stress, metallic surface smooth finish and specification precision can be improved, have certain chemical stability and minimizing to occur oil mark and filament surfaces defect.
