Abstract
The invention discloses a nitrogen-containing borate lubricating oil additive and a preparation method thereof and belongs to the technical field of lubricating oil. The preparation method comprises the following steps: firstly weighing raw materials according to the molar ratio of boric acid to cetanol to ethanol amine of (0.5-1.2):(0.5-3):(1-5); then adding the boric acid and the cetanol according to the molar ratio, adding a solvent, reacting for 0.8-1.2 hours at a temperature of 115-125 DEG C, then adding the ethanol amine according to the molar ratio, reacting for 4-6 hours and then refluxing. A nitrogen boron complex prepared by the invention instantaneously forms a ceramic boron nitride molecular film with super-strong wear resistance in a molecular form under the actions of temperature and pressure in a locomotive, has the efficacies of efficiently saving energy, reducing noise, protecting environment and prolonging the service life of the locomotive, is particular crucial for non-selectivity to metals and does not corrode a rubber sealing part; the additive can also efficiently slow down the rate of lubricating oil temperature rise and has more excellent performance in the high-temperature, high-speed and heavy-load locomotive; moreover, the raw materials are easy to obtain, the preparation method is simple, the cost is low, the hydrolytic stability is high, and the anti-wear and antifriction performances are good.
Description
technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a nitrogen-containing borate lubricating oil additive and a preparation method thereof. Background technique [0002] Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts. It mainly plays the roles of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. In order to enhance the above-mentioned effects of the lubricating oil, certain additives are often added to the lubricating oil. [0003] Existing lubricating oil additives are divided into many types. Among them, organic borate, as a new type of multifunctional lubricating oil additive, has excellent anti-friction and anti-wear properties, and has been widely used in various lubricating oils abroad; but like all esters, ordinary borate It is very easy to be hydrolyzed, r...
