Lubricant prepared from nano-material and preparation method thereof

Abstract

The invention discloses a lubricant prepared from a nano-material and a preparation method thereof. A modified anti-wear extreme pressure additive comprises the raw materials in parts by weight: 15-30parts 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-alpha-methylbenzenepropanal. The preparation method of the modified anti-wear extreme pressure additive comprises the following steps of (1) sequentially adding diisotridecylamine, molybdenum oxide and sodium benzoate into a reaction container, uniformly stirring the mixture for 2-3 h, reacting the mixture to prepare a molybdenum amine complex precursor; washing the precursor with alcohol, drying the precursor for 30 min; adding a certainamount of water solvent into the precursor and then stirring for 1-2 h. The nano-lubricant is smaller in grinding spot diameter so that the anti-wear extreme pressure property of the nano-lubricant is greatly improved, the energy consumption is further reduced, the wear is reduced, and the service life of the equipment is prolonged; the nano-lubricant has excellent oxidation resistance and stability performance, thereby prolonging the retention period of base oil; and meanwhile the nano-lubricant has a defoaming function and the thermal energy diffusion is avoided.

Description

Technical field [0001] The invention relates to the technical field of lubricants, in particular to a lubricant prepared from nano 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 contamination of the friction pair. In order to improve lubricating properties, suitable additives can be added to certain lubricants. When selecting lubricants, generally, factors such as the movement of the friction pair, materials, surface roughness, working environment and working conditions, and lubricant performance must be considered. In mechanical equipment, lubricants are mostly distributed to the parts that need lubrication through the lubrication system. Lubricants generally consist of two parts: base oil and additives. Base oil is the main component of lubricants and determines the basic properties of lu...

AI Technical Summary

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
