Lubricant for titanium-magnesium alloy drawing process and preparation method thereof

Abstract

The invention discloses a lubricant for a titanium-magnesium alloy drawing process. The lubricant is prepared from the following components in parts by weight: 1-4 parts of glycerol monostearate, 35-80 parts of LN32 mechanical oil, 3-10 parts of chlorinated paraffin, 4-15 parts of dimethyl silicone oil, 10-25 parts of di-n-butyl phosphite, 3-10 parts of lead naphthenate, 10-25 parts of triethanolamine oleate, 10-25 parts of poly-n-butyl vinyl ether, 20-35 parts of castor oil, 20-35 parts of glyceryl trioleate, 3-10 parts of a solid sulfur-based lubricating additive, 5-10 parts of a polymer lubricating additive and 5-15 parts of a stabilizing assistant. The lubricant disclosed by the invention can prevent the surface of a stamped workpiece from being scratched, rusted, the surface smoothness can be guaranteed, the demolding is easy, the dust hazard in a workshop is avoided, the production efficiency is improved, the preparation method disclosed by the invention is simple and feasible; the cost is low; the process controllability is high; and the preparation method is suitable for the production market demand of drawing lubricants.

Description

technical field [0001] The invention relates to the technical field of lubricants for drawing process, in particular to a lubricant for drawing process of titanium-magnesium alloy and a preparation method thereof. Background technique [0002] The inner wall lubricant of titanium and titanium alloy material cold extrusion forming drawing process, the existing technology is to use zinc stearate ultrafine powder to lubricate the workpiece, this technology pollutes the workshop environment greatly, and is harmful to the operators Great health hazard, risk of dust explosion and inhalation. It is inconvenient to use in operation, and it is also dangerous to a certain extent, and it is easy to be crushed by the machine. And the waste of this kind of lubricating way is extremely serious, and dust recovery is difficult, is difficult to reuse. [0003] At the same time, during the drawing process, titanium and titanium alloy materials are deformed, and if there is strong friction b...

AI Technical Summary

Problems solved by technology

[0004] The existing drawing lubricating oil has the following problems: serious adhesion between the workpiece and the mold makes it difficult to remove the film, and it cannot realize the rhythmic continuous operation, which affects the production efficiency; after the workpiece is stamped and stretched, it must be cleaned conventionally Otherwise, the surface of the workpiece cannot meet the requirements of direct assembly and use; after the workpiece is stamped and stretched, there will be scratches and microscopic fiber tearing on the surface; when lubricating oil is required for lubrication and cooling, the existing lubricating oil Compared with the cooling performance, the surface of the workpiece is easy to scratch and rust, and it is not easy to demould; the dust pollutes the environment, the operation is inconvenient for the workers, and it is very harmful to the body of the workers.
