Abstract
A kind of metal cool-press lubricating agent, belong to metal lubrication, by polyacrylamide, the aliphatic alcohol polyethenoxy phosphate kalium salt, alkylphenol polyoxyethylene, borax, trolamine are formed, and the present invention has omitted that the prior art cold stamping is lubricated must the cleaning step operation, make workpiece surface have better smoothness, the weldability of workpiece, but sprayability is all preferable, also has good rust-preventing characteristic simultaneously.
Description
At present domestic cool-press lubricating agent in industrial actual employing mostly is suds and machine oil, the emulsification wet goods, its weak point is after adopting suds, workpiece to be machined there is more serious corrodibility, quality to post-treatment operation such as spray paint also has certain influence, after adopting machine oil to do lubricant, remove oil reservoir as not cleaning, can't weld and spray paint at all, because cleaning dirty also have more flue gas to produce when welding, physical effects to the people is bigger, and matting is comparatively heavy.The early stage lubricant that is used for the punching press aspect abroad, most of is base oil with mineral oil, adds additive compound and forms.But owing to adopted mineral oil is base oil, so give the post-treatment operation, particularly welding and spray paint operation make a big impact, matting is equally also comparatively heavy, it is external aspect lubricant that to adopt more at present be to be the hydrographic lubricant of base oil to close generation oil, but all be to be used for cold rollingly, cold drawing-off and the lubricated aspect of cutting still are not used in the lubricant of cold stamping aspect.The domestic lubricant that is used for the cold stamping aspect that retrieves is that this patent body material of 88105113.6CN1040617A still is machinery oil, though this patent becomes simply matting, but still matting need be arranged.
The objective of the invention is to make cool-press lubricating agent satisfy solve cold-stamped part occur fracture, garden bullet, wrinkling, pull and cold punching die is lacked etc. on the basis of problem work-ing life, can satisfy the requirement of post-treatment operation, after the workpiece punching press is intact, need not clean.
Center of the present invention is: lubricant forms by following component is composite.
(1) polyacrylamide 0.5-1.5%
(2) aliphatic alcohol polyethenoxy phosphate kalium salt 0.5-2%
(3) alkylphenol polyoxyethylene 1.5-3%
(4) borax 1-3%
(5) trolamine 1-3%
Above-mentioned being weight percentage, surplus are water
In the above-mentioned raw materials be that generation oil is closed on the basis with the polyacrylamide; its effect is to make lubricant have good lubricity; reduce frictional coefficient; adopting the aliphatic alcohol polyethenoxy phosphate kalium salt is when the extreme boundary lubrication state; can form the workpiece protective membrane at the surface of friction place; improve lubricity, adopt alkylphenol polyoxyethylene to make the aqua lubricant that satisfactory stability be arranged.Increase adds the boron yarn and makes base oil keep stable oilness the wettability and the adsorptivity of workpiece, helps the weldering effect simultaneously, adds trolamine and makes lubricant have good rust-preventing characteristic.In the above-mentioned component, so, do not have flue gas during welding work pieces and produce just because of having adopted the polyacrylamide high molecular polymer that the cold stamping workpiece be need not to clean.Add other additive simultaneously, product of the present invention is had the following advantages.
Lubricant of the present invention has solved the weak point that occurs in the cold stamping, has omitted the cold-stamped cleaning step, has simplified the cold stamping manufacturing procedure and has made, the smooth finish that workpiece surface having is better, the workpiece weldability, but sprayability is all preferable, also has rust-preventing characteristic preferably simultaneously.
Be that the generality that the present invention carries out is described above, come that below by several embodiment the present invention is had more comprehensively understanding.
Embodiment 1, and composite 100 kilograms of required each components of metal cool-press lubricating agent all are unit with the kilogram
Polyacrylamide (viscosity-average molecular weight: 30 ± 20,000) 0.5 kilogram
1 kilogram of aliphatic alcohol polyethenoxy phosphoric acid ester first salt
1.5 kilograms of alkylphenol polyoxyethylene
2 kilograms of trolamines
1.5 kilograms of boraxs
Water surplus
70 ℃ of above each component Hybrid Heating are incubated 30 minutes, then cooling discharge.
The polyacrylamide that adopts in the above-mentioned raw materials can make with the following method and add 8% acrylamide solution in the reactor of stirring is housed, and adds 0.5% peroxidation agent catalyzer, uses N then
2Replace three times, start and be stirred under 40 ± 2 ℃ of temperature reaction promptly get molecular weight in 3-4 hour be 300,000 ± 20,000 polyacrylamide solution, reach following index through testing product of the present invention.
Effective ingredient 5-20%
PH value 7-9%
Frictional coefficient 0.113(Falex speed change four ball methods)
Oil film strength (PB) 74.5kg
Viscosity 42.5cp(rotary viscosity method)
Stability can be mixed with any ratio water
