Abstract
The invention discloses a lubricant composition for a cold spinning lead alloy pipe. The lubricant composition adopts 325SN base oil as base oil, and is cooperated with various additives, wherein the additives comprise an oiliness agent, an extreme-pressure agent, an antioxidant, an antiwear agent and a friction improver. The lubricant composition disclosed by the invention is relatively high in anti-milling property, adsorbing property, bearing property, soaking property and diffusing property, a uniform oil film with a certain thickness and certain oil film strength can be formed; the spinning friction coefficient is reduced, the adhesion and coking possibilities are lowered, and the lubrication performance, cooling performance, cleaning performance, and heat oxidation invariability performance are relatively high.
Description
Technical field
The invention belongs to extrusion process field of lubricant in intermetallic composite coating, particularly cold spinning lead alloy pipe lubricant compositions.
Background technology
Lead is bluish silvery white heavy metal, and it is toxic, is a kind of malleable main group metal.Fusing point 327.502 DEG C, boiling point 1740 DEG C, density 11.3437g/cm
3, hardness 1.5, quality is soft, and tensile strength is little.Lead is easy to get rusty---oxidation.Lead is often grizzly, be exactly due to it in atmosphere, very easily become the plumbous oxide of grey black by the dioxygen oxidation in air, make its argenteous gloss gradually become intensely dark.The important use of metallic lead manufactures store battery.The resistance to deformation of lead alloy is little, and the techniques such as extruding can be adopted to make sheet material, band, tubing, bar and wire rod.Because the shearing of lead alloy, creep strength are low, under certain load and rolling shear effect, lead alloy is easily deformable and thinningly become foil-like; And the self-lubricity of lead alloy, running-in ability and damping property are good, noise is little, because of but good bearing metal.Graphite metal and tinhase bearing metals are referred to as Babbitt metal, can make the Locomotive Bearing of high-load.Do not have the plumbous bright in color of zone of oxidation, density is high, and hardness is very low, and extensibility is very strong.Its conductivity is quite low, and corrosion resistance is very high, and therefore it is often used as the container of the strong material (such as sulfuric acid) of dress corrosion strength.Add the corrosion resistance that a small amount of antimony or other metal can improve it more.The tensile strength of lead alloy is 3 ~ 7kgf/mm
2, more much lower than other metal alloys of great majority.Antimony is for one of important element strengthening matrix, and only part is solid-solution in lead, both can be used for solution strengthening, and can be used for ageing strengthening again; If but too high levels, the toughness of lead alloy and solidity to corrosion can be made to degenerate.Consider from over-all properties, when lead alloy is for making the corrosion-resistant element such as chemical industry equipment, pipeline, to be advisable containing antimony about 6%; During for making transom, to contain antimony 8% ~ 10% as well.Lead antimony alloy adds a small amount of copper, arsenic, silver, calcium, tellurium etc., can gain in strength, be called antimonial lead.Lead alloy has not easily by the characteristic that X and gamma-rays penetrate, and can make the protective material of radiation work.
Cold spinning lead alloy pipe requires that lubricant compositions has higher wear-resistant, absorption, carrying, diffusibility, ensures that forming certain thickness even oil film also has certain oil film strength; Reduce the frictional coefficient of spinning, reduce adhesion and coking, and there is better lubrication, cooling, cleaning and thermal oxidation stability energy.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and has higher wear-resistant, absorption, carrying, infiltrate, diffusibility, ensures that forming certain thickness even oil film also has certain oil film strength; Reduce the frictional coefficient of spinning, reduce adhesion and coking, and have better lubrication, cooling, cleaning and thermal oxidation stability can cold spinning lead alloy pipe lubricant compositions.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
Cold spinning lead alloy pipe lubricant compositions, adopt oil based on 325SN base oil, coordinate multiple additives, its each component and mass percent thereof are:
| Component | Mass percent content |
| Base oil | Surplus |
| Oiliness improver | 8.0％～12.0％ |
| Extreme pressure agent | 3.0％～5.0％ |
| Oxidation inhibitor | 0.5％～1.2％ |
| Anti-wear agent | 3.0％～4.0％ |
| Friction improver | 1.0％～2.0％ |
Oiliness improver is industrial lard;
Extreme pressure agent is lead naphthenate;
Oxidation inhibitor is the dialkyl diphenylamine of mass ratio 50% and the phenolic ester type oxidation inhibitor T508 compound of 50%;
Anti-wear agent is that dibutyl dithiocaarbamate is plumbous;
Friction improver is molybdenum phosphate T451.
Remarkable advantage of the present invention has: have higher wear-resistant, absorption, carrying, infiltrate, diffusibility, ensures that forming certain thickness even oil film also has certain oil film strength; Reduce the frictional coefficient of spinning, reduce adhesion and coking, and there is better lubrication, cooling, cleaning and thermal oxidation stability energy.
