Abstract

The invention relates to environment-friendly metal cutting liquid and a preparing method thereof. The environment-friendly metal cutting liquid contains, by weight, 18-30% of base oil, 30-45% of non-ionic surfactant, 5.0-10.0% of anionic surfactant, 6-11% of composite antirust agent, 3.6-5% of coupling agent, 4.5-7% of extreme pressure agent, 0.1-0.2% of defoamer, 0.8-2.5% of bactericide and the balance water. The environment-friendly metal cutting liquid does not contain nitrite, heavy metal or toxic solvent and is an environment-friendly product, has excellent cleaning ability, anti-rust property, emulsion stability and defoaming property and has unique advantages in lubrication and bacteriostasis, and liquid waste is easy to treat and can be treated like general industrial wastewater after demulsification.

Description

technical field [0001] The invention relates to the technical field of metal cutting, in particular to a green metal cutting fluid and a preparation method thereof. Background technique [0002] The problem of environmental resources is an important problem facing mankind at present. Cutting fluid is widely used in modern metal cutting and has become an indispensable and important supporting material for machining. Most traditional metal cutting fluids use mineral oil as the base oil, which has poor biodegradability and can stay in water and soil for a long time, which will cause adverse effects on the environment and is not suitable as a green cutting fluid base oil. In addition, metal cutting fluid additives have various impacts on the environment. For example, short-chain chlorinated paraffin is one of seawater pollutants, and the antirust agent sodium nitrite is carcinogenic to the human body. Phosphate is commonly used in water-based cutting fluids. However, studies h...
