Abstract
The invention discloses a lubricant for drawing copper and a copper alloy rod. 100# II-type base oil is adopted as base oil and matched with a plurality of composite additives. The lubricant comprises an oiliness agent, an antiwear agent, an anti-foaming agent, an antioxidant, a friction modifier, a metal deactivator, a fortifier and an assistant. The lubricant for drawing copper and the copper alloy rod disclosed by the invention has strong adhesiveness, and is high in oil film strength, good in wearing quality, shearing resistance and viscosity-temperature characteristics, strong in extreme pressure property, good in thickness stability of the oil film and good in lubricating property, abrasion of a drawing tool and a drawing die is reduced, the lubricating has small flow shear stress, and has certain chemical stability and the ability of preventing rusty spots, and the surface glossiness and the specification accuracy of metal are improved.
Description
Technical field
The invention belongs to the field of lubricant of non-ferrous metal drawing processing, especially drawing copper and copper alloy rod.
Background technology
Copper is the non-ferrous metal very close with mankind's relation, is widely used in the fields such as electric, light industry, machinofacture, building industry, national defense industry, in the consumption of China YouSe metallic substance, is only second to aluminium.Copper is most widely used in electric, electronic industry, consumption is maximum, accounts for aggregate consumption over half.For various cables and wire, motor and transformer, in the manufacture of switch and printed-wiring board (PWB).In machinery and carrier vehicle manufacture, for the manufacture of industrial valve and accessory, instrument, sliding surface bearing, mould, heat exchanger and pump etc.In chemical industry, be widely used in manufacturing vacuum, still pot, brew-kettle etc.In national defense industry in order to manufacture bullet, shell, firearms part etc.In building industry, be used as various pipelines, pipe fitting, trim component etc.
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 copper and copper alloy rod (more than diameter 9mm) are that copper and copper alloy rod blank 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.
And the factor that affects copper and the drawing of copper alloy rod has conventionally: copper and copper alloy rod character (hardness, degree of cleaning, condition of surface); The material kind of drawing and drawing-die; The adaptability of drawing compound.Difference due to mode, condition and the range of product of drawing, also has difference to the requirement of lubricant.But conventionally require to have stronger adhesivity, oil film strength is large, and resistance to abrasion and sticky warm nature are good, extreme pressure property is strong, oil film thickness stability and oilness good etc.And lubricating method generally adopt immersion, brush, roll be stained with, traction or circulation etc.Therefore, drawing compound should meet many-sided requirements such as drawing process condition, industrial safety, economy, environmental friendliness, energy-conservation, reduction of discharging.
Summary of the invention
The technical problem to be solved in the present invention is to provide the lubricant of a kind of drawing copper and copper alloy rod, this lubricant has stronger adhesivity, oil film strength is large, resistance to abrasion, shear resistant and sticky warm nature are good, extreme pressure property is strong, oil film thickness stability and oilness 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, have certain chemical stability and prevent rust staining ability.
