High-property water-based cutting fluid for metal working and preparation method thereof

Abstract

The invention discloses a high-property water-based cutting fluid for metal working. The invention is characterized in that the cutting fluid is prepared from the following raw materials in parts by weight: 0.5-1 part of 1-hydroxybenztriazole, 2-3 parts of zinc sulfate, 2-4 parts of polysodium phosphate, 2-3.5 parts of hydraulic oil, 3.5-5 parts of sodium dodecyl benzene sulfonate, 2-3 parts of sulfurized haco oil, 1.5-2.5 parts of EDTA disodium, 0.8-1.5 parts of cuprous oxide, 5-7 parts of assistant and 200 parts of deionized water. By mixing the oily lubricating substance and surfactant, the cutting fluid has favorable lubricating property and enhances the product quality stability; by adding the 1-hydroxybenztriazole, sulfurized haco oil, hydraulic oil and the like, the extreme pressure abrasion resistance and rust resistance are enhanced, and the metal surface can not be easily abraded; and by adding the assistant, the cutting fluid has favorable abrasion resistance, dispersity, lubricating property and film formation property. Due to the adoption of the water-based formula, the cutting fluid has the advantages of favorable cleaning property, favorable cooling property, stable quality and low tendency to deterioration, and is easy to store and suitable for metal working.

Description

technical field [0001] The invention relates to the field of cutting fluid, in particular to a water-based cutting fluid for metal processing with good performance and a preparation method thereof. Background technique [0002] In the machining industry, lubricating oil or Bupleurum oil plus lubricating oil is basically used for cutting lubrication and cooling. In the process of processing, the waste of oil is extremely serious, and it causes great harm to the environment and operators; and it is difficult to obtain an ideal processing surface. Moreover, the heat dissipation speed is slow during processing, and the workpiece is easy to rust after processing. 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 wate...

Generally, oil-soluble cutting fluid has good lubricating performance, but poor cooling performance, and contains a large amount of organic matter, polluting the environment

Although some water-soluble cutting fluids have good cooling performance, they also have the problem of poor lubricity and anti-rust effect. Cutting fluid that does not corrode the equipment and does not pollute the environment is very important
