Description

Description '' Technical Field of Lubricating Oil Composition

The present invention relates to a water-soluble lubricating oil composition, and more particularly, to a metal working oil such as a cutting oil and a plastic working oil, an antifouling mixture adhesion inhibitor, and a concrete. The present invention relates to a water-soluble lubricating oil composition suitable as a release oil such as a release agent. Background art

Examples of lubricating oils used as metal working oils such as cutting oils and plastic working oils used in the processing of metals and ceramics are water-insoluble types using mineral oils or synthetic oils as base oils. However, emulsion-type ones containing these substances are used. In recent years, in the processing of metals and ceramics, water-soluble metal processing oils and the like are frequently used in consideration of the danger of ignition due to high processing speed and high feed rate. Since such water-soluble metalworking oils are usually used after being diluted in water, emulsification stability at the time of dilution is important. Poor emulsification stability causes variations in processing accuracy and contamination of the machine periphery. Therefore, a metal working oil (lubricating oil) having excellent emulsion stability is desired.

In addition, when a lubricating oil based on mineral oil or synthetic oil as described above is used, if the mineral oil or synthetic oil leaks into soil or the like, there is a risk of causing environmental pollution.

On the other hand, as a technology for paving a wide range of surfaces such as roads and sports grounds, the ground is made flat, and then the heated mixture is spread over the ground. Construction work has been widely carried out to make the asphalt mixture in a uniform state using rolling means such as pavement rollers and to make pavement. If compaction is performed using the above-mentioned rolling means such as a stirrer in asphalt work, adhesion will occur between the roller and the asbestos contact area, and the asbestos will be applied to the roller. There is a problem that the mixture adheres and the surface of the pavement has irregularities, and the quality of the pavement deteriorates. The asphalt mixture used in the above-mentioned asphalt construction is usually loaded on a truck bed and transported. During such transportation, there was a problem that the asphalt mixture adhered to the truck bed.

Conventionally, mineral oils such as heavy oil, light oil, waste engine oil, and water have been widely used for the purpose of preventing asphalt mixture from adhering to rollers and the like.

However, the use of only water cannot prevent the asphalt mixture from adhering depending on the properties of the asphalt mixture and construction conditions (weather conditions, etc.). In addition, when mineral oils such as heavy oil and light oil are used, the mineral oils have a high solubility of asphalt components, so that the asphalt may be altered to cause stepping stones and the like. In addition, there was no sufficient effect of preventing asphalt mixture from adhering to iron-made items such as truck beds and load rollers.

In particular, the drainage type asphalt mixture, whose use has been rapidly increasing in recent years, has a problem that the adhesion is strong due to its high viscosity and the adhesion preventing effect is low with mineral oils. In addition, mineral oils were sown on the ground and underground as a result of asphalt construction, which was a major environmental problem. In addition, when mineral oils are used, they have high solubility in the asphalt mixture, and may damage the painted surface such as discoloration and reduced viscosity.

To solve the above problems, water-soluble cutting oil for metal working has been used, and research and development to solve the above problems have been conducted. For example, Japanese Patent No. 2736660 discloses an asphaltic adhesion inhibitor containing a nonionic surfactant of a sorbitan fatty acid ester or a polyoxyethylene sorbitan fatty acid ester. Also, Japanese Patent Application Laid-Open No. H10-112018 discloses adhesion of a heated asphalt mixture containing sodium alkyl sulfate, sodium alkyl ether sulfate, water and coconut oil. Inhibitors are disclosed. According to the asphalt adhesion preventing agent disclosed in the above publication, the asphalt adhesion preventing effect is exhibited to some extent, but the asphalt adhesion preventing effect is not sufficient.

In the case of producing concrete products, the majority of them use molds to harden the concrete into the desired shape. At this time, a concrete release agent is used for the purpose of facilitating removal of the formwork without sticking the formwork and concrete and protecting the formwork. Have been. The concrete release agent is used by being applied to the inner surface of the mold in advance before the concrete is driven. Conventionally used concrete release agents are based on mineral oils such as light oil and machine oil, and require various additives such as waxes, metal lithographs, and fire retardants. It was added accordingly. They are also classified into oil-based types, emulsion types, and soluble types, depending on how they are used.

As such a concrete releasing agent, for example, Japanese Patent Application Laid-Open No. 5-64828 includes a phospholipid and a sorbitan fatty acid ester or an ethylene oxide adduct thereof. A concrete release agent comprising a mineral oil-based solvent is disclosed. The concrete release agent disclosed in this publication achieves the effect of reducing the contamination of the mold and preventing the mold, but uses a mineral oil-based solvent, and thus is environmentally and safety-friendly. Was inadequate. As mentioned above, in the field of concrete release agents, functional and environmental At present, there is no product developed from the aspect point of view.

Accordingly, metal working oils such as cutting oils and plastic working oils, asphalt mixture adhesion preventives and concretes which can reduce environmental pollution while having excellent emulsification stability. A water-soluble lubricating oil composition suitable as a release oil such as a release agent is desired.

Accordingly, an object of the present invention is to provide a metal working oil such as a cutting oil and a plastic working oil, an anti-adhesive mixture adhering agent, and a concrete, which are capable of reducing environmental pollution while having excellent emulsion stability. An object of the present invention is to provide a water-soluble lubricating oil composition suitable as a release oil such as a release agent. Disclosure of the invention
