Environmental protection cutting liquid

Abstract

The present invention relates to an environmental protection cutting liquid, which is prepared from ethylene glycol, sodium metasilicate, sodium phosphate and water according to a certain weight part ratio. The environmental protection cutting liquid has good stability, does not generate precipitating or layering, oil precipitating, soap graining, aging and other phenomena during storage and use, provides a certain resistance ability for bacteria and fungi, and is not easily subjected to mould generation and biodegradation so as not to cause odor generation and deterioration. In addition, the environmental protection cutting liquid has characteristics of no damage on painted parts, no harm on human body, no irritating odor, no smoke, no fog or less smoke during a use process, easy recovery, and low pollution.

Description

technical field [0001] The invention relates to a cutting fluid, in particular to an environment-friendly cutting fluid. Background technique [0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, chipping and grinding. [0003] With the continuous improvement of people's understanding of cutting fluid and the continuous enrichment of practical experience, it is found that injecting oil into the cutting area can obtain a good machined surface. At the earliest, people used animal and vegetable oils as cutting fluids, but animal and vegetable oils are perishable and have a short service life. At the beginning of the 20th century, people began to refine lubricating oil from crude oil, and invented various lubricating additives with excellent performance. After the First World War, the research and use of compound oils synthesized from mineral oils and animal and vegetable oils began. In 1924, cutting oil c...
