Abstract
The invention relates to a cutting fluid for metal processing, and particularly relates to a polyethylene glycol monooleate fully-synthetic cutting fluid and a preparation method thereof. Polyethylene glycol monooleate is used as a lubricating agent, and borate generated by boric acid and monoethanolamine and triazine amino-acid ester are combined to form an anti-rust component which has better anti-rust property, thus solving the defects of poor lubricating property, easy deterioration and smelliness and short service life of polyethylene glycol lubricating agents, polyether lubricating agents, oleic acid soap lubricating agents and sulfonated caster oil lubricating agents, and further achieving a corrosion inhibition and synergy function by adding a proper amount of benzotriazole copper corrosion inhibitor and other anti-rust agents. The fully-synthetic cutting fluid prepared from the raw materials is complete in property, has excellent hard water resistance, can be used under a high hard water environment, is high in pH buffer capacity, is stable in quality, has excellent lubricating, anti-rust and anti-corrosion functions, belongs to an environment-friendly product, can be biodegraded, is suitable for various kinds of machining, and is especially suitable for various machining processes of a grinder.
Description
technical field [0001] The invention relates to a metal processing cutting fluid, in particular to a fully synthetic polyethylene glycol oleate cutting fluid and a preparation method thereof. Background technique [0002] With the development of the global industry, the demand for energy is increasing, and the storage of non-renewable energy such as petroleum on the earth is becoming less and less, which leads to an increasingly tight supply of base oil; for this reason, we have developed a A high-performance fully synthetic cutting fluid without base oil; Compared with emulsified cutting fluid and microemulsion cutting fluid, fully synthetic cutting fluid does not contain any mineral oil, and is completely composed of inorganic and organic chemical substances. It has excellent cooling, Cleaning performance, but traditional fully synthetic cutting fluid lubricants are mainly composed of polyethylene glycol, polyether, oleic acid soap, and ancient oil, but these lubricants ei...
