Abstract
The present invention relates to powder used in metallurgy low temperature lubricants.Powder used in metallurgy low temperature lubricant, according to mass parts meter, comprising: the fatty acid salt and 10~30 parts of plasticizer that fatty acid amide that 5~30 parts of paraffin, 10~50 parts of microwaxes, 10~30 parts of fusing points are 60-80 DEG C, 10~30 parts of fusing points are 90-110 DEG C.The range using temperature at 40-60 DEG C of powder used in metallurgy low temperature lubricant disclosed by the invention, in this temperature range, variation more originally: 1, energy consumption sharp fall is had occurred in entire technical process, and production cost reduces；2, the traditional lubrication of mold movement component is not destroyed, and can be operated normally；3, excessive differential thermal expansion is resolved, the improper failure probability decline of mold；4, under conditions of 40-60 DEG C of forming temperature, no matter powder or mold system, temperature field is more uniform, and the probability for being pressed into blank for obtaining even density is higher.
Description
Technical field
The invention belongs to mold compression moulding powder metallurgy industry fields, and in particular to powder used in metallurgy low temperature lubricant.
Background technique
Thermal-pressing powder metallurgy lubricant used at present is all to have lubrication and drop under conditions of 130-150 DEG C in the market
Low compaction pressures improve the lubricant system of pressed density, in 130-150 DEG C of at a temperature of heating mould and powder, obtain high
The powder compact of pressed density
But above-mentioned lubricant system haves the defects that the following aspects:
1. the energy consumption that heating powder and mold need is high, especially large-scale sintered metal product, single product weight is big, mould
Have size it is big, maintain mold and with raw material at 130-150 DEG C, need a large amount of energy, waste of energy is serious, hot briquetting at
This is very high；
2 130-150 DEG C at a temperature of, for mold movement mechanism lubrication binder effect decline, mold be easy damage
It is bad, die life decline；
3 130-150 DEG C at a temperature of, mold be heated portion of (cavity plate etc.) dilation dimension and other guiding parts
Size different variation mold accuracy declines occurs, be easy to produce abnormal damage, die life decline, production cost mentions
It is high；
4 sensitive heating temperature ranges cause, and warm compaction molding actual effect is not very ideal in complicated die structure,
Pressed density is sometimes only in 7.2 gram per centimeters3It nearby hovers, properties of product are far below horizontal reported in the literature
Summary of the invention
Goal of the invention: the present invention has made improvements in view of the above-mentioned problems of the prior art, i.e., the invention discloses powder
Metallurgy low temperature lubricant.
Technical solution: powder used in metallurgy low temperature lubricant, according to mass parts meter, comprising:
5~30 parts of paraffin, 10~50 parts of microwaxes, the fatty acid amide that 10~30 parts of fusing points are 60-80 DEG C, 10~30 parts
Fusing point is 90-110 DEG C of fatty acid salt and 10~30 parts of plasticizer.
Further, microwax is ethylene bis stearamide.
Further, the fatty acid amide that fusing point is 60-80 DEG C is oleamide or stearyl erucamide.
Further, the fatty acid salt that fusing point is 90-110 DEG C is ferric stearate or iron oleate.
Further, plasticizer is dibutyl phthalate (DBP) or stearic acid butyl ester.
The above binder constituent element serves as different components in forming lubricant, at a temperature of low melting point constituent element is as temperature and pressure
Transition liquid-phase occurs, and increases lubricating function, and high-melting-point constituent element prevents powder and mold from alloy occurs as die wall lubrication ingredient
Change；Plasticizer reduces the viscosity of the liquid phase at a temperature of temperature and pressure, improves lubricant effect
The utility model has the advantages that the range using temperature at 40-60 DEG C of powder used in metallurgy low temperature lubricant disclosed by the invention,
In this temperature range, variation more originally is had occurred in entire technical process:
1, energy consumption sharp fall, production cost reduce；
2, the traditional lubrication of mold movement component is not destroyed, and can be operated normally；
3, excessive differential thermal expansion is resolved, the improper failure probability decline of mold；
4, under conditions of 40-60 DEG C of forming temperature, no matter powder or mold system, temperature field is more uniform, obtain it is close
The probability that degree is uniformly pressed into blank is higher.
