Multifunctional fully-synthetic cutting fluid and preparation method thereof

Abstract

The invention discloses multifunctional fully-synthetic cutting fluid and a preparation method thereof. The multifunctional fully-synthetic cutting fluid is prepared from modified vegetable oil, organic carboxylic acid amide, borate, ethanolamine, a polyether activating agent, a non-ferrous metal corrosion inhibitor, triethanolamine oleate, ethanolamine citrate, triethanolamine phosphate, emulsified silicone oil and the like. According to the multifunctional fully-synthetic cutting fluid and the preparation method thereof, an easily-biodegradable special additive combination is adopted, so that the problem that similar products on the market are generally poor in lubricity and rust resistance is solved; a formula does not contain nitrite, benzene and phenol substances, so that waste liquid is easy to process, the destruction to the environment can not be caused, and the environmental friendliness is good; and the multifunctional fully-synthetic cutting fluid can be applied to medium / heavy-load cutting processing and is applicable to automated production equipment, such as numerically-controlled machine tools, processing centers and the like.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid, in particular to a multifunctional fully synthetic cutting fluid and a preparation method thereof. Background technique [0002] The water-based synthetic cutting fluid is in accordance with the national standard GB7631.5-89 "Classification of Lubricants and Related Products (Class L) Part 5; Group M (Metal Processing)", the symbols MAG and MAH correspond to two synthetic cutting fluids. L-MAG type; the concentrate mixed with water is a transparent liquid with anti-rust properties. When used, it is diluted with a certain proportion of water to form a transparent and translucent dilution. It is suitable for various cutting processes such as metal turning and milling. Cooling, antirust; L-MAH type; MAG type concentrate with antifriction and extreme pressure properties. [0003] The national standard GB / T6144-2010 "Synthetic Cutting Fluid" of the People's Republic of China is revised on the b...

AI Technical Summary

Problems solved by technology

[0007] Fully synthetic cutting fluid is composed of a variety of chemical components and does not contain mineral oil. Therefore, the lubricating performance and extreme pressure performance of fully synthetic cutting fluid are relatively poor. Generally, it cannot be used for medium and heavy-duty cutting. In order to achieve the anti-rust effect, Many fully synthetic cutting fluid products on the market contain cheap anti-rust agent nitrite. Nitrite is a potential carcinogen. Long-term exposure will affect the health of operators

In addition, the synthetic cutting fluids in the prior art also have disadvantages such as poor lubricity, low extreme pressure value, weak anti-rust ability and insufficient compatibility.
