Problems solved by technology

[0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators.
[0003] In order to solve these problems, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology solves the above problems such as large amount of lubricant used and serious pollution. At the same time, in order to make the micro-quantity lubricant used have relatively strong extreme pressure and anti-wear Sex and lubricity, excessive use of sulfur- and chlorine-containing additives that are not friendly to the environment, it is a meaningful research topic to study a micro-lubricant additive that does not contain sulfur and chlorine and has excellent extreme pressure and anti-wear properties. Since the B-N type lubricating oil composition has relatively good extreme pressure anti-wear and anti-rust properties, the research on the B-N type lubricating oil composition material is also of practical significance

Abstract

The invention provides a boron-nitrogen type lubricating oil composition, which is prepared from dimer acids, triethanolamine, and boric acid; wherein the mole ratio of dimer acids to triethanolamineis 0.5-1.5:1; and the mole ratio of triethanolamine to boric acid is 2-3:1. The prepared boron-nitrogen type lubricating oil composition can be used as a B-N type extreme pressure anti-wear agent andan antirust agent and has a good degradable property. The invention provides a trace lubricating oil prepared from the boron-nitrogen type lubricating oil composition. The trace lubricating oil also comprises iso-nonyl iso-nonanoate, castor oil maleate, aliphatic alcohol phosphate, and the like. The prepared trace lubricating oil can satisfy the requirements on the lubricating performance, coolingperformance, extreme pressure anti-wear performance, and antirust performance in metal processing. Under the assistance of a trace lubricating device, the using amount of the lubricating agent is reduced by 95% or more. The energy consumption and emission are reduced, and the environment protection effect is prominent.
