Abstract

The invention relates to a polyricinoleate phosphate and a preparation method thereof, and application of the polyricinoleate phosphate in preparing biodegradable trace cutting oil. The invention is characterized in that the molecular structural formula of the polyricinoleate phosphate is disclosed in the specification. The polyricinoleate phosphate can be mixed with low-viscosity ester to prepare trace cutting oil. The trace cutting oil has favorable lubricating property extreme pressure antiwear property; a slight amount of trace cutting oil can satisfy the high-end requirement for metal working, thereby reducing the harm to the environment and workers; and the trace cutting oil is biodegradable, thereby minimizing the environmental pollution.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to polyricinoleic acid phosphate, a preparation method thereof, and the use of the ester to prepare biodegradable micro-cutting oil. Background technique [0002] Cutting oils, coolants, emulsions and other lubricants used in traditional metal processing lubrication and cooling are used in large quantities, and traditional cutting oils use mineral oil as the base oil, which is not easy to decompose in the natural environment, and most of the additives used are harmful to the human body. Harmful to the environment, it not only wastes resources, but also causes huge pollution of processing sites and the environment. In recent years, the research on micro-cutting technology has made great progress, which has reduced the harm caused by the discharge of a large amount of cutting oil to the environment. However, in order to solve the problem of micro-cutting, excessive amounts of chlo...
