Embodiment 1

[0025] According to the percentage by weight in Table 1, weigh 3 grams of hexahydro-1,3,5-trihydroxyethyl-s-triazine, 10 grams of BA60DX, 6 grams of succinic acid, 10 grams of diethanolamine, and 5 grams of sulfurized fatty acid Soap, 0.4 g of benzotriazole, 20 g of triethanolamine and 45.09 g of water are heated and dissolved at a temperature of 50 to 70 ° C, stirred evenly, then 0.5 g of 6501 and 0.01 g of emulsified silicone oil are added, and the stirring is continued until uniform to obtain Pale yellow transparent liquid. The liquid was diluted with water at a ratio of 5% by weight to obtain a diluted liquid.

[0026] The powder alloy material used in the cobalt suppression performance test was obtained from a processing workshop and then finely ground. During the test, first measure 100 ml of diluent, then add 5 grams of cobalt-containing powder alloy material, shake fully for 2 minutes, place it at room temperature, and then shake once every 8 hours. Gram company's an...

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...
