Problems solved by technology

[0002] Traditional metal cutting generally uses mineral oil / vegetable oil / 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. Healthy body
[0003] In order to solve these problems, some progress has been made in the recent research on micro-quantity lubrication technology at home and abroad. The micro-quantity lubrication technology has solved the problems of large amount of lubricant used and serious pollution. Excessive use of sulfur and chlorine-containing lubricants that are not friendly to the environment additive

Abstract

The invention provides a lubricant composition which is characterized in that the lubricant composition is prepared from konjac polysaccharide and myristic acid; the weight ratio of the konjac polysaccharide to the myristic acid is: 100 parts ofkonjac polysaccharide; and 100-120 parts of myristic acid. The preparation method comprises the following steps: adding konjac polysaccharide and myristic acid into a reaction kettle, adding a catalyst, and reacting for 3-5 hours at the temperature of 180-220 DEG C under the protection of nitrogen; removing moisture under reduced pressure in the reaction process; obtaining the konjac polysaccharide myristate. The konjac polysaccharide myristate is a good nonionic surfactant and lubricant, and has good lubricating performance; meanwhile, the biodegradability is good, and the environment-friendly effect is achieved. The invention also provides a bio-based environment-friendly trace lubricant containing the lubricant composition. The bio-based environment-friendly trace lubricant is prepared from the following components: the lubricant composition, polyacrylic acid myristyl alcohol ester, rhamnolipid, myristyl alcohol lactate, sodium dioctyl sulfosuccinate, di-myristyl alcohol phosphate and deionized water.
