Cutting liquor composition for metal processing

Abstract

The invention discloses a cutting liquid composition to manufacture metal, which comprises the following parts: 0.1-10% cobalt-inhibiting additive with triazine, 0.5-40% antirust agent, 0.05-5% corrosion inhibitor, 0.2-20% pH value adjustor and tap water, basic oil or composition to manufacture cobalt knife or cobalt manufacturing material in the cutting manufacturing course.

Description

technical field [0001] The invention relates to a cutting fluid composition for metal processing. Background technique [0002] In metal processing tools, cobalt-containing cemented carbide is more and more widely used. During the machining of these knives and the use of these knives for metalworking, the metal cobalt in the material dissolves into the cutting fluid, turning the fluid pink or dark red. The continuous leaching of cobalt not only accelerates the corrosion loss of tools and materials and the accuracy of workpieces. More importantly, the harm of cobalt to human health and the natural environment is strictly controlled by environmental regulations. According to medical research, cobalt not only causes human asthma and bronchial fibrosis, but also affects the heart, skin, thyroid and blood cells. Therefore, reducing the content of cobalt in the working environment as much as possible is the goal pursued by people. Using special cutting fluids that inhibit coba...

Problems solved by technology

However, after the discharge of phosphorus-containing water-soluble cutting fluid waste, it is easy to produce phosphorus-enriched effects on water bodies.

[0004] The cobalt inhibitors disclosed in the above-mentioned documents all do not relate to the problem of being able to simultaneously solve the problem of inhibiting microbial growth.
