Problems solved by technology

[0006] However, these water-soluble metalworking oils either do not have a sufficient anti-corrosion effect, or for effective oils, halogen-containing compounds, polycyclic aromatic compounds, phenolic compounds, or metal salts are used. Among them, there are some compounds that become the target substances of PRTR, so there is concern about the effect on the human body

Embodiment

[0040] For each oil agent for metalworking shown in Tables 1 to 4, the anticorrosion test was evaluated by the following method.

[0041] The oils shown in Tables 1 and 3 are water-soluble metalworking oils using mineral oil or synthetic base oil (alkylbenzene), and the oils shown in Tables 2 and 4 are natural base oils (rapeseed oil) Water-soluble metalworking oil.

[0042] Anti-corrosion test

[0043] In the liquid 100ml that each oil agent is diluted to 2% by mass with sterilized water, add 10ml of the following spoilage bacteria liquid ( * 1) After vibrating culture at 30°C for 2 weeks, the number of viable bacteria was measured.

[0044] * 1 spoilage liquid

[0045] Emulsion-type cutting fluid with deterioration of corruption 10.0% by mass

[0046] Tryptic Soy Broth 1.0% by mass

[0047] Glucose-peptone medium 1.0% by mass

[0048] Sterilized water 88.0% by mass

[0049] As the spoilage solution, the spoilage bacteria solution of the above-mentioned mixture cultur...

Abstract

Disclosed is a water-soluble metalworking fluid having excellent decay resistance, which is widely applicable to metalworking such as cutting, grinding, form rolling, pressing and plastic working. Also disclosed is a metalworking method using such a metalworking fluid. Specifically disclosed are a metalworking fluid characterized by containing a morpholine compound and an isothiazoline compound, and a metalworking method using such a metalworking fluid.

Description

technical field [0001] The present invention relates to a kind of oil agent for metal processing which can be widely used in metal processing such as cutting processing, grinding processing, rolling processing, pressure processing and plastic processing, and a metal processing method using the same. A water-soluble metalworking oil used in dilution, particularly a water-soluble metalworking oil excellent in corrosion resistance, and a metalworking method using the same. Background technique [0002] Generally, cutting and grinding oils are used in cutting and grinding. The most important functions of cutting and grinding oils include lubricating and cooling functions. These functions can prolong the life of tools used in processing, improve the surface accuracy of workpieces, and improve production efficiency. Improve productivity. [0003] Conventional oils for metalworking include water-insoluble types that are used as they are in a stock solution state, and water-solubl...
