Problems solved by technology

[0003] Micro-quantity cutting technology is a new metal green processing technology developed in recent years. It is to use a micro-quantity lubrication system to spray a micro-quantity lubricating oil with good extreme pressure, anti-wear and lubricity on the processing tool and the processing surface during the metal cutting process. , cooling, to solve the problems of large amount of cutting oil and fluid used in traditional processing, and large waste and leakage. However, in order to achieve a good lubrication and cooling effect, the trace lubricating oil currently used often contains a large amount of chlorine and sulfur, which has a certain impact on the environment. At the same time, the micro-lubricant used is often not easy to degrade in nature, which has a certain impact on the environment

Abstract

The invention provides biodegradable micro-lubricating oil. The biodegradable micro-lubricating oil is characterized by comprising fatty acyl sarcosine with the mass percent content being 5-10%, wherein the fatty acyl sarcosine is prepared from carboxylic acid and sarcosine through acylation reaction. The biodegradable micro-lubricating oil provided by the invention has good biodegradability, and good extreme pressure antiwear property and lubricating property, and is used by matching with a micro-lubricating device; the usage amount can be reduced to below 5% of the original amount; good lubricating and cooling effects are achieved; and the biodegradable micro-lubricating oil has significant benefits of energy conservation and emission reduction, and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a biodegradable trace lubricating oil and a preparation method thereof. Background technique [0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication and cooling. 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. In good health. Today, when energy conservation, emission reduction, environmental protection, and green production are advocated, a new metal cutting process is urgently needed. [0003] Micro-quantity cutting technology is a new metal green processing technology developed in recent years. It is to use a micro-quantity lubrication system to spray a micro-quantity lubricating oil with good extreme pressure, anti-wear and lu...
