Embodiment 1

[0068] A) 90 parts of rapeseed oil and B) 10 parts of polyoxyethylene sorbitan tetraoleate (added with 30 moles of EO) were heated to 70°C respectively, and they were mixed and dissolved while fully stirring to obtain the Water-soluble lubricating oil composition. Various evaluations were performed on the obtained water-soluble lubricating oil composition according to the following "evaluation criteria for water-soluble lubricating oil composition". The evaluation results are shown in Table 1 (Experiments (1) to (5)) and Table 2 (Experiments (6) to (8)).

[0069] [Evaluation Criteria for Water-Soluble Lubricating Oil Compositions]

[0070] (1) Friction coefficient

[0071] The obtained water-soluble lubricating oil composition was diluted 10 times with water, and the friction coefficient of the diluted solution was measured with a vibration friction loss tester (manufactured by Optomol Co., Ltd.). The measurement conditions are as follows.

Embodiment 2

[0124] A) 80 parts of soybean oil, 10 parts of palm oil and B) 10 parts of polyoxyethylene sorbitan tetraoleate (30 moles of EO added) were each heated to 70°C, and mixed while fully stirring dissolved to obtain the water-soluble lubricating oil composition of the present invention. The obtained water-soluble lubricating oil composition was evaluated in the same manner as in Example 1. The evaluation results are shown in Table 1 (Experiments (1)-(5)) and Table 2 (Experiments (6)-(8)).

Embodiment 3

[0126] A) 90 parts of rapeseed oil and B) 8 parts of polyoxyethylene sorbitan tetraoleate (addition of 30 moles of EO) and 2 parts of polyoxyethylene sorbitan tetraoleate (addition of 60 moles EO) were each heated to 70° C., mixed and dissolved with sufficient stirring, to obtain the water-soluble lubricating oil composition of the present invention. The obtained water-soluble lubricating oil composition was evaluated in the same manner as in Example 1. The evaluation results are shown in Table 1 (Experiments (1)-(5)) and Table 2 (Experiments (6)-(8)).

Abstract

The water-soluble lubricating oil composition of this invention contains animal fats and oils and/or plant fats and oils, and the nonionic surfactant of polyoxyethylene sorbitol fatty acid ester. The water-soluble lubricating oil composition of this invention is excellent in emulsion stability, and it can reduce environmental pollution. It is suitably as metal processing oils such as cutting oil and plastic working oils, and release agent such as asphalt mixture adhesion prevention agent and concrete release agent.

Description

technical field [0001] The present invention relates to a water-soluble lubricating oil composition, in particular to a water-soluble lubricating oil composition suitable for metal processing oils such as cutting oils and plastic processing oils, anti-adhesion agents for asphalt mixtures, and release oils such as concrete release agents. Lubricating oil composition. Background technique [0002] As lubricating oils that can be used as metalworking oils such as cutting oils and plastic working oils in the processing of metals and ceramics, water-insoluble types using mineral oils or synthetic oils as base oils (base oils), or lubricating oils that use These oils include water-formed emulsion type lubricating oils and the like. In recent years, in the processing of metals or ceramics, water-soluble metal processing oils and the like have been widely used in consideration of the risk of fire due to increased processing speed and high conveyance. Since this water-soluble metal...
