Abstract
The present invention relates to metal cold drawing processing lubricant and a preparation method thereof. The lubricant is prepared from animal oil fat, sodium hydroxide, sodium silicate, rosin, sodium phosphate and water. The method includes the steps that the water, the rosin and the animal oil fat are mixed and heated to melt; the sodium hydroxide is added after the mixture is stirred; the mixture is continuously stirred until materials start to agglomerate; the sodium silicate and the sodium phosphate are orderly added in the process of stirring; the lubricant is prepared after stirring and mixing. The lubricant replaces the phosphorization and saponification processing technology and does not have the problem of environment pollution for the phosphorization and saponification processing. Besides, the surface quality is improved, the processing technique is simplified, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of metal cold working lubricant, particularly relate to a kind of cold drawing of metal lubricant and preparation method thereof.
Background technology
At present, cold drawing of metal industry institute is with lubricator various in style, and the different metal kind is suitable for different separately lubricants with complete processing.Add man-hour at the metal of certain this kind such as the cold-drawn of ferrous metal, stretch and anti-extreme pressure intensity in order to improve, and enhancing lubrication, must be after pickling, earlier the cold-drawn starting material are carried out phosphatization and saponification processing, outstanding cost height and the problem of environment pollution caused of existing of this phosphatization and saponification treatment process, and through the steel surface that phosphatization and saponification the are handled blackening that can become fragile.
Summary of the invention
The objective of the invention is to overcome the above-mentioned shortcoming of prior art, provide a kind of and possess phosphatization saponification function, and can improve the cold drawing of metal lubricant of surface quality of steel, the present invention also provides its preparation method.
For achieving the above object, the present invention is formed through following method hybrid reaction by the following weight proportion raw material: animal grease 70-90, sodium hydroxide 8-15, water glass 2-7, rosin 1-5, sodium phosphate 0.5-4, water 50-100.
The water that in reactor, adds specified amount earlier, add rosin and animal grease again, be heated to material melting, stirred 1-2 hour at 100-150 ℃, stir afterwards and slowly add sodium hydroxide down, continue to be stirred to material and begin caking, under agitation successively add water glass and sodium phosphate again, continue stirring and promptly can be used as the finished product discharging in 10 minutes.
As optimization, described sodium phosphate preferably phosphoric acid disodium hydrogen.
Preparation method of the present invention may further comprise the steps: the water that adds specified amount earlier in reactor, add rosin and animal grease again, be heated to material melting, stirred 1-2 hour at 100-150 ℃, stir afterwards and slowly add sodium hydroxide down, continue to be stirred to material and begin caking, under agitation successively add water glass and sodium phosphate again, continue stirring and promptly can be used as the finished product discharging in 10 minutes.
As optimization, the material temperature that continues behind the described material melting to stir 1-2 hour is 100-120 ℃.
Cold drawing of metal lubricant of the present invention meets following quality standard: kinematic viscosity (50 ℃) is not more than 6.3, pH value is not less than 12.
The using method of cold drawing of metal lubricant of the present invention is, earlier steel are carried out cleanup acid treatment, then, the bath that the cold-drawn lubricant of 1.5 weight parts is put into, the water that adds 100 weight parts again, heat then to 50-60 ℃ and make water and cold-drawn lubricant thorough mixing, to need the steel of cold-drawn to immerse in the mixed solution at last, the above-mentioned mixed solution of steel surface absorption one deck after 2 minutes, dry after going out the pond, steel surface adheres to the transparent film of one deck 0.02-0.04 mm thick, its tensile strength and anti-extreme pressure intensity, and lubrication is identical with the steel of handling through phosphatization and saponification.
Cold drawing of metal lubricant of the present invention is owing to have with phosphatization and the identical effect of saponification processing, use this lubricant can replace phosphatization and saponification treatment process, and the problem of environmental pollution that does not exist phosphatization and saponification to handle, can improve surface quality of steel, solve surface embrittlement blackening problem, and can simplify complete processing, reduce the production cost of this treatment process.
