Abstract

The invention provides novel environmentally-friendly cutting liquid and a preparation method thereof. The novel environmentally-friendly cutting liquid is prepared from the following raw materials inparts by weight: 18-26 parts of N5 white oil, 8-15 parts of coconut oil fatty acid diethanolamide, 3-9 parts of extrcme pressure antiwear additive, 7-14 parts of antirust agent, 2-5 parts of emulgator, 1.2-2 parts of ethyl alcohol, 2-4 parts of anticorrosive agent, 3-7 parts of defoamer, 0.5-1.6 parts of mildew preventive and 20-27 parts of water. The cutting liquid prepared by the preparation method has the advantages of environment protection, high stability and excellent lubrication, rust prevention, cooling and cleaning performance.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a novel environment-friendly cutting fluid and a preparation method thereof. Background technique [0002] Machining is developing in the direction of high speed, strength and precision. For some materials with extremely high hardness, it is more difficult to cut them. Because there is a large friction force in the cutting process, in order to obtain a better machined surface, people have been working on improving the lubrication and antirust properties of cutting fluids for many years. Additives in traditional cutting usually contain sulfur, phosphorus, and chlorine compounds. Although they have a certain effect, these substances will pollute the environment, and sulfides are easy to cause corrosion to non-ferrous metals. With the enhancement of people's awareness of environmental protection, many substances with high toxicity and unsatisfactory anti-rust and lubricating properties ar...
