Near dry cutting fluid and preparation method thereof

Abstract

A near dry cutting fluid is prepared from the following raw materials in parts by weight: 10-12 parts of a polyalkylene glycol, 1-2 parts of sodium benzoate, 4-6 parts of hydantoins, 1-2 parts of triethanolamine, 1-2 parts of sodium diisopropylnaphthalenesulphonate, 3-4 parts of isopropyl myristate, 1-2 parts of polydimethylsiloxane, 3-5 parts of sodium ethylenediamine tetramethylene phosphonate, 20-24 parts of glycerol, 10-12 parts of kerosene, 6-8 parts of an auxiliary agent and 200 parts of water. The cutting fluid provided by the invention is good in permeability and is capable of rapidly penetrating a processing area and realizing the comprehensive rapid lubrication effect by employing isopropyl myristate; the cutting fluid comprises the performances such as lubricity, cleaning performance, corrosion inhibition, antirust property, extreme-pressure wear resistance and the like, so that the cutting speed is substantially improved and the usage amount of the cutting fluid is substantially reduced; and when applied to a near dry cutting apparatus, the usage amount of the cutting fluid is reduced to 8% of the original usage amount, so that the cost is saved and the environment pollution is reduced.

Description

Technical field [0001] The invention relates to the technical field of cutting fluids, in particular to a quasi-dry cutting fluid and a preparation method thereof. Background technique [0002] The cutting fluid should have good cooling performance, lubrication performance, anti-rust performance, degreasing cleaning function, anti-corrosion function, and easy dilution characteristics. At present, cutting fluids can be divided into two categories, oil-soluble cutting fluids and water-soluble cutting fluids. Generally, oil-soluble cutting fluids have good lubrication performance, but poor cooling performance, and contain 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. Therefore, the research and development combines lubricity, cooling, rust resistance, easy cleaning, non-toxic, odorless, non-corrosive to human body, and Cut...
