Abstract
The invention discloses a lubricant for drawing tin and an alloy material thereof. 15# total loss system oil is adopted as base oil and matched with a plurality of composite additives. The lubricant comprises an oiliness agent, an antiwear agent, an extreme pressure agent, an anti-foaming agent, an antioxidant and a friction modifier. The lubricant for drawing tin and the alloy material thereof disclosed by the invention has strong diffusivity and permeability, and is high in oil film strength, good in wearing quality and viscosity-temperature characteristics, strong in extreme pressure property, good in cooling property and lubricating property, and small in flow shear stress, abrasion of a drawing tool and a drawing die is reduced, the surface glossiness and the specification accuracy of metal are improved, and the lubricant has certain chemical stability, proper flash point and ignition point, is the lubricant which is low in viscosity, low in sulfur content, low in aromatic hydrocarbon, and convenient to use and clean.
Description
Technical field
The invention belongs to the field of lubricant of non-ferrous metal drawing processing and lubrication, particularly drawing tin and alloy material thereof.
Background technology
Tin, metallic element, a kind of low melting point metal element of slightly bluish white gloss, is argenteous soft metal, and proportion is 7.3, and fusing point only has 232 ℃, puts the liquid that just can be melt in coal dust ball stove as mercury into.Tin is very soft, with pocket knife, can cut it.The chemical property of tin is very stable, is difficult for being at normal temperatures oxidized by oxygen; Therefore, it often keeps the glittering gloss of silver.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, can make the product of multiple style, 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.
Conventionally the resistance to deformation of tin and alloy thereof increases with drawing deformation amount, should select effective lubricant and lubricating method, is lubricated, cleaning, cooling and reduce nib and drawing part adherent phenomenon, the damage that minimizing drawing part surface adhering causes.
Drawing is one of main production method of tubing, bar, section bar and wire rod.Press goods cross-sectional shape, drawing can be divided into: solid material drawing and the large class of hollow material drawing two.Drawing tin and alloy material thereof are that tin and alloy material blank thereof are imposed to pulling force, make it by nib to obtain the plastic processing method with nib sectional dimension, goods that shape is identical.
In drawing process, the friction except between material, drawing-die and steel core, on contact surface, because drawing speed improves, will occurrence temperature sharply rise.In order reducing, in drawing process, to there is heavy wear or sintering, thereby to require lubricant to play antifriction and wear prevention, cooling, lubricated effect; Be improved drawing speed and section reduction rate simultaneously, to improve output and the quality of drawing process processing, prevent the generation of the defects such as surface tear, fold, bending, bias, crackle, broken end, metal are pressed into.Guarantee output and the quality of drawing process processing.
Summary of the invention
The technical problem to be solved in the present invention is to provide the lubricant of a kind of drawing tin and alloy material thereof, this lubricant has stronger diffusion and perviousness, oil film strength is large, resistance to abrasion and sticky warm nature are good, and extreme pressure property is strong, Cooling and Lubricator is good, reduces the wearing and tearing of drawing device and drawing-die, there is less mobile shear-stress, improve metallic surface smooth finish and specification precision, and have certain chemical stability and suitable flash-point and point of ignition, low viscosity, low sulfur-bearing, low aromatic hydrocarbons.
The present invention is usingd following technical scheme and is solved the problems of the technologies described above: adopt No. 15 total loss systems with oil as base oil, coordinate multiple composite additive, its each component and mass percent are:
| Component | Content (mass percent) |
| Base oil | Surplus |

| Oxidation inhibitor | 1.5%～2.0% |
| Friction improver | 0.5%～3.0% |
| Kilfoam | 0.01%～0.02% |
Base oil is No. 15 oil for total loss system.
Oiliness improver is industrial lard.
Anti-wear agent is tritolyl phosphate.
Extreme pressure agent is dialkyldithiocarbamacompositions tin.
Oxidation inhibitor is that N-phenyl-a-naphthylamine and 40%～50% the 2,6 ditertiary butyl p cresol of mass ratio 60%～50% is compound.
Friction improver is that sulphur molybdenum phosphate and 40%～50% the boric acid molybdenum of mass ratio 60%～50% is compound.
Kilfoam is dimethyl silicone oil.
The lubricant of drawing tin of the present invention and alloy material thereof, have stronger diffusion and perviousness, oil film strength is large, and resistance to abrasion and sticky warm nature are good, extreme pressure property is strong, Cooling and Lubricator is good, reduce the wearing and tearing of drawing device and drawing-die, have less mobile shear-stress, improve metallic surface smooth finish and specification precision, there is certain chemical stability, having suitable flash-point and point of ignition, is the lubricant of low viscosity, low sulfur-bearing, low aromatic hydrocarbons, easy to use and cleaning.
