Abstract

Provided is a cutting fluid containing waste engine oil. The cutting fluid is prepared from the following raw materials, by weight, 12-14 parts of waste engine oil, 1-2 parts of triethanolamine, 4-6 parts of amino-acid ester, 2-3 parts of phytic acid, 2-3 parts of dodecyl dimethyl benzyl ammonium chloride, 1-2 parts of nanoscale graphite micropowder, 14-16 parts of diethylene glycol monobutyl ether, 5-8 parts of propylene glycol, 1-2 parts of sodium laurate, 6-8 parts of auxiliary agents and 200 parts of water. Through application of nanoscale graphite micropowder, the cutting fluid has excellent lubricating property and extreme pressure resistance. Through application of waste engine oil, the cost is lowered. The cutting fluid has good antirust performances, contains no substances of sodium salt, phenol, chlorinated paraffin, mineral oil and the like, has no damage to human body, and is a environmentally friendly and green product.

Description

technical field [0001] The invention relates to the technical field of cutting fluid, in particular to a cutting fluid containing waste engine oil and a preparation method thereof. Background technique [0002] The cutting fluid should have good cooling performance, lubricating performance, anti-rust performance, degreasing and cleaning function, anti-corrosion function, and easy dilution. At present, cutting fluid can be divided into two categories, oil-soluble cutting fluid and water-soluble cutting fluid. Generally, oil-soluble cutting fluid has good lubricating performance, but poor cooling performance, and contains a large amount of organic matter, which pollutes the environment. Although some water-soluble cutting fluids have good cooling performance, they also have the problem of poor lubricity and anti-rust effect. It is very important to have a cutting fluid that does not corrode the equipment and does not pollute the environment. Contents of the invention [0...
