Embodiment 1

[0020] According to the percentage by weight in table 1, take by weighing 15 gram ethanolamine borates, 5 gram sodium molybdates, 20 gram monoisopropanolamine, 8 gram monoethanolamine, 4 gram oleic alcohol amine soaps and 32 gram water respectively, in Heat to dissolve at 50-70°C, then add 6 grams of 5-n-octyl tetrazolium and 10 grams of AEO-9, and continue stirring at constant temperature until completely uniform, and a light yellow transparent liquid can be obtained. A diluted solution obtained by adding water to the liquid according to a 5% weight ratio.

[0021] 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 milliliters of diluent, then add 5 grams of cobalt-containing powder alloy material, shake it and let it stand. After 5 days, the amount of cobalt dissolved in the liquid was determined with an analytical stick from Merck. The lower the cobalt...

Abstract

The invention discloses a cutting liquid composition, which is characterized by the following: allocating the cutting liquid composition with antirust agent, alcohol amine, inorganic alkaline or their composition, tetrazoline compound and water; fitting for manufacturing knife with cobalt or each cutting course.

Description

technical field [0001] The invention relates to a cutting fluid composition, in particular to a cutting fluid composition which is used in the cutting process of cobalt-containing processed materials and has the ability to inhibit metal cobalt from seeping out. Background technique [0002] With the development of science and technology, more metal materials are applied to industry. Metal cobalt is used as a powder alloy binder, added to powder metal carbide (tungsten carbide, titanium carbide, etc.) matrix, and made into tungsten-cobalt cemented carbide by pressing and high-temperature sintering. This material has extremely high hardness and wear resistance, and is widely used in many parts that are easy to wear on aero-engines, pump columns, grinding rings, bushing parts in the petrochemical field, and high-performance molds. The most widespread is the manufacture of high-efficiency cutting tools. [0003] When the tungsten-cobalt alloy material is processed with ordinar...
