Abstract
The invention discloses a lubricant combination for a cold spinning copper alloy tube. The lubricant combination is characterized by adopting 250SN base oil as base oil and cooperating with various additives including an oiliness agent, a friction modifier, an anti-wear agent, an anti-oxidation preservative and a metal deactivator. The lubricant combination disclosed by the invention is enough in oil film thickness, higher in diffusivity and permeability, high in oil film strength, good in wear resistance and viscosity-temperature property, high in extreme pressure property, good in cooling, cleaning and lubricating properties and smaller in flow shear stress, improves the surface smoothness and the side and specification precision of the metal tube, has a certain chemical stability and proper flash points and ignition points and is low in viscosity, low in sulfur and low in aromatics.
Description
Technical field
The invention belongs to metal working lubricant field, particularly cold spinning tin alloy pipe lubricant compositions.
Background technology
Tin, metallic element, a kind of low melting point metal element of white gloss of bit bluish is argenteous soft metal, and proportion is 7.3, and fusing point only has 232 DEG C, puts in coal dust ball stove the liquid that just can be melt into as mercury into.Tin is very soft, can cut it with pocket knife.The chemical property of tin is very stable, is not easily oxidized by oxygen at normal temperatures; Therefore, it often keeps silver-colored glittering gloss.Tin is nontoxic, and plasticity-is strong and ductility is very poor, can not pull into filament.It can have various process of surface treatment, the product of multiple style can be made, tin remains the indispensable crucial rare metal of modern industry, is known as " industrial monosodium glutamate ", is widely used in the industries such as electronics, information, electrical equipment, chemical industry, metallurgy, building materials, machinery, food product pack.
The resistance to deformation of usual cold spinning tin alloy pipe increases with rotary pressure deformation amount and increases, effective lubricant and lubricating method should be selected, carry out lubricating, clean, cool, protection against corrosion and reduce adhesion and phenomenon, reduce damage and spot that tube surface causes because lubrication and cooling is bad.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind ofly has enough oil film thicknesses, stronger diffusion, perviousness, oil film strength is large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, cooling, cleaning and oilness good, have less flowing shear-stress, improve surface smoothness and the dimensions precision of metal tube, and have certain chemical stability and suitable flash-point and point of ignition, the cold spinning tin alloy pipe lubricant compositions of low viscosity, low sulfur-bearing, low aromatic hydrocarbons.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
Cold spinning tin alloy pipe lubricant compositions, adopt oil based on 250SN base oil, coordinate multiple additives, its each component and mass percent thereof are:
| Component | Mass percent content |
| Base oil | Surplus |
| Oiliness improver | 5.0％～6.0％ |
| Friction improver | 2.0％～3.0％ |
| Anti-wear agent | 2.0％～3.0％ |
| Oxidation inhibitor | 0.1％～0.3％ |
| Antioxidant preservative | 0.1％～0.7％ |
| Metal passivator | 0.5％～1.0％ |
Oiliness improver is ethyl oleate.
Friction improver is phosphoric acid ester.
Anti-wear agent is sulphur phosphoric acid nitrogen containing derivative.
Oxidation inhibitor is 2,6 ditertiary butyl p cresol T501.
Antioxidant preservative is dialkyldithiocarbamacompositions tin.
Metal passivator is thiadiazole.
Remarkable advantage of the present invention has: have enough oil film thicknesses, stronger diffusion, perviousness, oil film strength is large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, cooling, cleaning and oilness good, have less flowing shear-stress, improve surface smoothness and the dimensions precision of metal tube, and have certain chemical stability and suitable flash-point and point of ignition, low viscosity, low sulfur-bearing, low virtue.
