Abstract

The invention provides polysucrose fatty acid ester which is characterized by comprising or being prepared from sucrose, dicarboxylic acid and fatty acid at a mole ratio of 1:(1-1.5):(1-2). Due to the rich vacancy-OH, the polysucrose fatty acid ester provided by the invention can be effectively adhered to surfaces of processed metals, is excellent in lubrication property, extreme pressure antiwear property and rusting resistance, and can completely or partially replace conventional extreme pressure antiwear agents used in micro-scale lubricating oil, and only the micro-scale lubricating oil can meet the requirements of lubrication cooling, extreme pressure antiwear property and rusting resistance in metal processing, and when the polysucrose fatty acid ester is used with a micro-scale lubricating device, the use amount of cutting fluid can be reduced by more than 95%, and remarkable effects of energy conservation, emission reduction and environmental protection can be achieved.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a polysucrose fatty acid ester, a preparation method thereof, and a micro-quantity lubricating oil prepared from the ester. Background technique [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 has solved the above problems such as large amount of lubricant used and serious pollution, but the research on micro-quantity lubricant still has certain limitations in application. The problem is that th...
