Lubricant prepared from nanomaterials and preparation method thereof

Abstract

The invention discloses a lubricant prepared from nanomaterials and a preparation method thereof. The parts by weight of the raw materials in the modified anti-wear extreme pressure agent are 15-30 parts of diisotridecylamine, 17-25 parts of molybdenum oxide, 1-3 parts of sodium benzoate, 3-11 parts of emulsified silicone oil and 1-8 parts of isopropyl-α-methylphenylpropionaldehyde; the preparation method of modified anti-wear extreme pressure agent comprises the following steps: 1) diisodecyl Triamine, molybdenum oxide and sodium benzoate are sequentially added into the reaction vessel, stirred evenly for 2-3 hours, and the molybdenum amine complex precursor is obtained by reaction, the precursor is washed with alcohol, and dried for 30 minutes; then a certain amount is added to the precursor A small amount of water solvent and then stir for 1-2 hours; the diameter of the nano-lubricant wear scar is smaller, which improves the anti-wear and extreme pressure performance of the nano-lubricant, further reduces energy consumption, reduces wear, and improves the service life of the equipment; And it has very good anti-oxidation and stability properties, thus prolonging the shelf life of the base oil. At the same time, it has the effect of defoaming and avoids the diffusion of heat energy.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to a lubricant prepared from nanometer materials and a preparation method thereof. Background technique [0002] Lubricant is a lubricating medium used to reduce the friction resistance of the friction pair and slow down its wear. Lubricants can also cool, clean and prevent pollution on the friction pair. In order to improve the lubricating performance, suitable additives can be added to some lubricants. When selecting a lubricant, it is generally necessary to consider many factors such as the movement of the friction pair, the material, the surface roughness, the working environment and working conditions, and the performance of the lubricant. In mechanical equipment, lubricants are mostly delivered to the parts that need to be lubricated through the lubrication system. Lubricants generally consist of base oil and additives. Base oil is the main component of lubricants, whic...

Problems solved by technology

[0003] The existing lubricants have relatively low anti-wear and extreme pressure properties, which cannot reduce energy consumption, reduce wear, and improve the service life of equipment. Moreover, the existing lubricants do not have good oxidation resistance and stability, which prolongs the foundation The shelf life of oil; lubricant is an insulating protective layer, which can isolate the heat generated by metal friction, thereby avoiding damage to the machine caused by excessive temperature, but various additives work together to easily generate air bubbles and defoaming Equivalent to a hole in the insulating layer, heat energy can diffuse through this bubble
