Problems solved by technology

It has the characteristics of high viscosity index, good viscosity-temperature performance, good wear resistance, high flash point, low volatility, non-toxic, easy biodegradation, and no adverse effects on the environment, but the physical properties of vegetable oil are affected by the structure and composition of fatty acids. It is easy to oxidize at high temperature and has a high pour point. Compared with mineral oil base oil, its performance at high and low temperatures is not ideal
Modified vegetable oil can overcome the above deficiencies, but the four-ball test on ordinary soybean oil, high oleic soybean oil, and epoxy soybean oil shows that epoxidized vegetable oil has the best oxidation stability and the worst wear resistance

Abstract

The invention provides vegetable oil-based water-soluble cutting fluid. The cutting fluid comprises, by weight, 5%-20% of vegetable oil and / or modified vegetable oil, 15%-35% of a synthetic ester of the vegetable oil, 5%-15% of water, 2%-12% of an emulsifier, 0%-2% of a dispersant, 15%-30% of an alkaline reserve agent, 0%-3% of a corrosion inhibitor, 0%-3% of a descaling agent, 0%-3% of a extremepressure agent, 0%-2% of a bactericide and 0%-2% of a antifoaming agent. With the present invention, the semisynthetic cutting fluid adopting the vegetable oil as the raw material has excellent oxidation resistance, excellent abrasion resistance and substantial lubrification; a problem of partial ecological toxicity due to mineral oil is solved such that the cutting fluid is green environmental protection and biodegradable; the cutting fluid is applicable for a variety of processing materials, and provides excellent anti-rust property for the non-ferrous metals.

Description

technical field [0001] The invention relates to a preparation method of a semi-synthetic water-soluble cutting fluid prepared from vegetable oil. Background technique [0002] With the continuous development and application of new metal materials, metal processing speed and load continue to increase, metal processing fluid must have the characteristics of high quality, multi-function and versatility. At present, according to the composition of processing oil and the state of the medium, it is divided into two categories: oil-based and water-based. They have their own advantages in different processing techniques. The former has excellent lubrication and anti-rust performance, while the latter has better cooling and cleaning performance. superior. In order to meet different market demands, oil-based and water-based, semi-synthetic emulsions are the development trend of metalworking fluids and are very popular in the market. [0003] Due to the poor biodegradability of miner...
