Abstract

The invention discloses a method for preparing a nanoscale lubricant additive, comprising the following steps: A, preparing solutions: weighing calcium chloride and boric acid according to the proportion of 1:2 of Ca and B and dissolving the calcium chloride and the boric acid respectively; B, carrying out ultrasonic reaction: mixing the two solutions by ultrasonic processing and stirring, adding a surfactant, and subjecting the solutions and the surfactant to reaction at room temperature to obtain a white emulsion; and C, extracting products: adding the mixed solution of oleic acid and petroleum ether into the white emulsion, processing ultrasonically and stirring continuously until a lower layer aqueous solution is clear and transparent, standing for layering, taking an upper white oil-phase precipitation, and drying to obtain the nano calcium borate lubricant additives, wherein the mixed solution of the oleic acid and the petroleum ether is used as the extractant. The performance of the lubricant additive is greatly improved, the process for preparing the lubricant additive is greatly simplified, and the cost for preparing the lubricant additive is reduced.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to a lubricating oil additive. Background technique [0002] Friction and wear are ubiquitous in nature and can lose more than 50% of the world's primary energy. In addition, friction and wear are also one of the main reasons for the scrapping of materials and equipment. Therefore, various methods such as lubricating oil or solid lubrication are used to reduce the negative effects of friction and wear. But friction and wear still cause tens of billions of economic losses to our country every year. Therefore, reducing friction, reducing wear, and prolonging mechanical life are the goals that researchers in tribology, chemistry, and materials are constantly pursuing. [0003] Nanomaterials are known as "the most promising materials in the 21st century", and they have great potential in transforming traditional materials. The research and application of nanomaterials in the fie...
