Abstract

The invention discloses a fully synthetic metal working fluid formula for improving lubricity and a preparation method of the fully synthetic metal working fluid formula. The fully synthetic metal working fluid formula comprises the following components in percentage by weight, 0.1 to 1 percent of hyaluronic acid, 5 to 10 percent of trans-block polyether, 2 to 4 percent of isononanoic acid, 2 to 4percent of monoethanolamine, 4 to 6 percent of triethanolamine and the balance of water. According to the invention, hyaluronic acid is dissolved in water, can be adsorbed on the surface of metal ata high temperature during processing to form a uniform and firm matrix film, and can lock a large amount of moisture, and trans-block polyether in the moisture can be precipitated on the surface of the metal when being precipitated at the high temperature, so that an excellent cooling and lubricating effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of metalworking fluids, and in particular relates to a formula and a preparation method of a fully synthetic metalworking fluid with improved lubricity. Background technique [0002] With the rapid development of industrial production, in recent years, the rapid development of my country's machining, especially precision machining, and the continuous emergence of new materials, the continuous improvement of environmental protection requirements, traditional semi-synthetic and emulsified cutting fluids, because they contain more mineral oil The components have high requirements for post-processing, and many processing plants have begun to try to use fully synthetic cutting fluids that are completely oil-free instead. Fully synthetic cutting fluid does not contain oil, has good transparency and excellent cooling performance, and is currently the object of general research. However, the oil-free fully synthetic...
