Technical Field

The invention belongs to the technical field of lubricating oil, and particularly relates to long-acting guide rail oil and a preparation method thereof.

Background

The guide rail oil can be used for machine tool guide rails of lathes, planing machines, grinding machines, milling machines, CNC (computer numerical control) machining centers and the like, and is very important to machining precision and equipment service life.

The working environment of the guide rail is severe, and the guide rail usually does reciprocating motion under the condition of bearing large load, and even does rapid reciprocating pulse motion. The metal contact surface of the guide rail often generates cutting scratches and metal fatigue strain in different degrees; the gears and the racks of the driving device, and the lead screw (ball screw) and the sliding block are abraded due to poor lubrication, so that the precision is gradually lost; the guide rail oil cannot be completely isolated from the metal cutting fluid, and the adhesive force is difficult to ensure under the continuous scouring state; the phenomenon of "crawling" is unavoidable.

With the continuous upgrade of metal processing machinery, the rail oil efficacy cannot be limited to rust prevention, lubrication, anti-foaming, anti-emulsification, and needs to be improved in the following aspects: (1) the thickness, toughness and adhesion of the oil film; (2) effective metal surface repair and strengthening functions; (3) the friction coefficient is reduced; (4) the service life is prolonged.
