Abstract

A kind of lubricant of drawing aluminium and aluminium alloy pipe, adopt based on the I class base oil of No. 460 oily, coordinate multiple composite additive, comprise oiliness improver, anti-wear agent, extreme pressure agent, antioxidant preservative, oxidation inhibitor, friction improver, metal passivator, antioxygen auxiliary agent.The lubricant of drawing aluminium and aluminium alloy pipe of the present invention, strength of lubricant film is large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, thickness stability and oilness good, reduce the wearing and tearing of drawing device and drawing-die, there is less flowing shear-stress, improve metallic surface smooth finish and specification precision, have certain chemical stability and prevent the features such as hickie ability.

Description

The lubricant of drawing aluminium and aluminium alloy pipe

Technical field

The invention belongs to the field of lubricant of non-ferrous metal drawing processing and lubrication, particularly drawing aluminium and aluminium alloy pipe.

Background technology

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 aluminum pipe imposes pulling force to aluminum pipe 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.

And the factor affecting aluminum pipe drawing has usually: aluminum pipe character (hardness, degree of cleaning, condition of surface); The material kind of drawing and drawing-die; The adaptability of drawing compound.Due to the difference of the mode of drawing, condition and range of product, also there is difference to the requirement of lubricant.But usually require to have stronger adhesivity, oil film strength is large, resistance to abrasion and sticky warm nature 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 a kind of lubricant of drawing aluminium and aluminium alloy pipe, this lubricant has stronger adhesivity, strength of lubricant film is large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, thickness stability and oilness good, reduce the wearing and tearing of drawing device and drawing-die, have less flowing shear-stress, improve metallic surface smooth finish and specification precision, have certain chemical stability and prevent the features such as hickie ability.

The present invention solves the problems of the technologies described above by following technical scheme: adopt based on the I class base oil of No. 460 oily, coordinate multiple composite additive, its each component and mass percent are:

Component

Content (mass percent)

Base oil	Surplus
		Oiliness improver	8.0%～10.0%
Anti-wear agent	3.0%～7.0%
		Extreme pressure agent	3.0%～5.0%
Oxidation inhibitor	0.5%～1.0%
		Friction improver	3.0%～5.0%
Metal passivator	1.0%～2.0%
		Antioxidant preservative	0.5%～1.0%
Antioxygen auxiliary agent	0.5%～0.8%

Base oil is the I class base oil of No. 460.

Oiliness improver is industrial lard.

Anti-wear agent is sulphur phosphoric acid nitrogen containing derivative.

Extreme pressure agent is boronation phosphoric acid ester.

Oxidation inhibitor is the right of mass ratio 60% ~ 50%, right '-di-iso-octyldiphenylamine and 40% ~ 50% 2,6 ditertiary butyl p cresol compound.

Friction improver is alkyl phosphite.

Metal passivator is 124 Triazole derivative.

Antioxidant preservative is dialkyl dithiophosphoric acid sulfuration oxygen copper.

Antioxygen auxiliary agent is sulphur phosphorus fourth octyl group zinc salt.

The lubricant of drawing aluminium and aluminium alloy pipe of the present invention, strength of lubricant film is large, resistance to abrasion and sticky warm nature good, extreme pressure property is strong, thickness stability and oilness good, reduce the wearing and tearing of drawing device and drawing-die, there is less flowing shear-stress, improve metallic surface smooth finish and specification precision, have certain chemical stability and prevent the features such as hickie ability.
