Lubricant for metal cold working and preparation method thereof

Abstract

The invention discloses a lubricant for metal cold working and a preparation method thereof. The lubricant is mainly composed of PAO poly alpha olefin synthetic oil, aquadag, molybdenum disulfide, butter and nanocarbon. Wherein the mass percent of each component is as follows: 10%-90% of PAO poly alpha olefin synthetic oil, 5%-20% of aquadag, 0.5%-10% of molybdenum disulfide, 0.5%-55% of butter and 0.001%-5% of nanocarbon; in addition, a complete process for preparing the lubricant is provided. The lubricant provided by the invention is simple in preparation method, ingredients are easy to purchase, and the cost is reduced; the lubricant can effectively reduce the friction coefficient in the metal cold working process, can be prepared into a liquid state or a paste state to be coated on the surface of a metal workpiece according to the requirements of on-site working conditions, and is beneficial to rapid diffusion of heat in the machining process, so that it is ensured that the machining process is orderly, stable and continuous.

Description

Technical field [0001] The present invention belongs to the technical field of lubricant, and more particularly to a metal-cold working lubricant and a preparation method thereof, which can be applied to zirconium, titanium or other metal tube, rod, plate, strip, rolling, squeezing , Pull the cold processing process. Background technique [0002] Metal materials are the basic materials for national economic development, and are widely used in aerospace, military, mechanical manufacturing, construction, transportation, nuclear reactions, atomic energy and other fields. [0003] According to the actual demand, the metal material is processed into silk materials, bar, tubing, and sheets. It is well known that metal materials have high deformation and high deformed resistance, so the high temperatures caused by friction and plastic deformation during cold processing, resulting in bonding the workpiece and mold, resulting in damage to the surface quality of the workpiece. Good lubrica...

Problems solved by technology

Such as publication number CN104164284A provides a kind of steel wire drawing lubricant, this lubricant is mainly made up of substances such as tallow, lime, paraffin, the steel wire surface quality that uses this lubricant to prepare is good, but this lubricant usage is relatively large, and The drawing speed is limited and cannot be too fast, thereby affecting the production progress; secondly, when the shape of the workpiece is complex, the lubricant cannot effectively cover the inner surface of the workpiece, resulting in poor surface quality of the workpiece after cold working; The preparation method of graphene modified lubricant has the advantages of small friction coefficient, good wear resistance, and less surface residue. However, this water-based lubricant must be used immediately after being coated on the surface of the workpiece, otherwise it will be damaged after a long period of storage. Agglomeration is easy to occur, and during the multi-pass cold working process, the processing heat generated prevents the lubricant from forming a continuous lubricating film on the workpiece, resulting in a decrease in lubricating performance

Due to the corresponding defects of the above lubricants, they cannot be well adapted to the metal cold working process.
