Problems solved by technology

[0003] In order to improve the performance of lubricants, researchers add appropriate friction modifiers and other additives to lubricants to reduce friction loss under mixed and boundary lubrication conditions. The more commonly used and effective additives are diamond nanoparticles, but Diamond nanoparticles are more expensive, which increases the preparation cost of lubricating oil. In addition, the dispersion of particles in lubricating oil with diamond nanoparticles or other particle additives is not good, resulting in the effect of lubricating oil not being able to achieve the expected effect.

Abstract

The invention relates to the technical field of lubricating oil, and in particular, relates to a numerically-controlled machine tool lubricant and a preparation method thereof. The numerically-controlled machine tool lubricant is mainly composed of the following raw materials: an oxygen-containing organic compound, oxidized polyethylene, acrylic acid, vulcanized lard oil, an extrusion anti-wear agent, an antirust agent, a dispersing agent, a nanoparticle composition and the balance being base oil for lubricating oil. Cobalt powder and rhodium powder are matched for use; trace rhodium powder isadded into the cobalt powder; a new phase mainly containing rhodium is separated out under the action of high temperature; the phase exists in the form of a separate phase, and a binding phase whichis dissolved in the cobalt powder and the rhodium powder rarely play a reinforcing role on the bonding phase; the face-centered cubic structure of rhodium provides a stable structural environment forbeta-Co of the face-centered cubic structure; alpha-Co crystals are inhibited from being converted into beta-Co crystals to a certain extent, so that the composition composed of the cobalt powder andthe rhodium powder can replace diamond nano-particles, and the effect of extremely well reducing friction loss under the mixing and boundary lubricating conditions is achieved.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a numerically controlled machine tool lubricant and a preparation method thereof. Background technique [0002] Lubricants are commonly used preparations in the structure of industrial equipment such as CNC machine tools, and are substances used to lubricate, cool and seal the friction parts of machinery. According to the source lubricants are divided into mineral lubricants (such as machine oil), vegetable lubricants (such as castor oil) and animal lubricants (such as tallow). In addition, there are synthetic lubricants, such as silicone oil, fatty acid amides, oleic acid, polyester, synthetic ester, carboxylic acid, etc. [0003] In order to improve the performance of lubricants, researchers add appropriate friction modifiers and other additives to lubricants to reduce friction loss under mixed and boundary lubrication conditions. The more commonly used and effective a...
