Abstract

PURPOSE:To provide the title composition excellent in lubricity, rustproofness, oxidation stability, etc., and safe for the human body by mixing a base oil comprising liquid paraffin with a specified amount of a 12-22C saturated fatty acid as essential constituent. CONSTITUTION:A base oil comprising liquid paraffin is mixed with 0.01-1wt.%, based on the whole composition, 12-22C saturated fatty acid as essential constituent to produce a lubricating oil composition. Examples of the saturated fatty acid include myristic acid, palmitic acid, and stearic acid. In addition, the incorporation of dibutylhydroxytoluene and/or a tocopherol (e.g. alpha-tocopherol) serves to further improve the lubricating oil performance. The obtained composition is suitably employed as lubricating oil for a compressor used in manufacturing foods, medicines, etc., in particular.

に用いられる潤滑油組成物に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lubricating oil composition, and more particularly to a lubricating oil composition used in equipment such as compressors.

るいは医療機関で使われるケースは極めて少ない。[Prior art] Compressed air used in food-related industries, medical equipment, pharmaceutical manufacturing, medical care, and other areas that may affect the human body is usually a combination of an oil-cooled compressor and a mist filter. There are many ways to use it. The smallest oil-free compressor currently available is 15KI! Since the equipment cost is more than twice that of the oil-cooled type, it is rarely used in small to medium-sized manufacturing plants or medical institutions.

が系外に出る可能性を持っている。Examples of the use of compressed air in areas that come into contact with the human body and are likely to have an impact include stirring food such as ice cream, peeling vegetables such as onions (instantly blowing off the skin), miso, etc. For stirring during the fermentation of foods, for blowing away spilled dirt when filling soft drink and liquor bottles, for cleaning bottles, for transporting powders such as sugar, for dentists' hand air drills. There are air sources and throat cleaning uses, etc.
When an oil-cooled device and a mist filter are combined, it is extremely difficult to completely remove oil mist from compressed air over a long period of time, and there is a possibility that even several ppm to several tens of ppm of oil may escape from the system. ing.

防止能力も要求される。Furthermore, when producing dry ice by compressing CO2 gas, screw type compressors are generally used in medium to large scale factories. Since the lubricating oil used at this time lubricates the equipment while coming into direct contact with this gas, a lubricating oil that takes into account safety for the human body is used when using dry ice. In addition, since there is a trace amount of air mixed in, oxidation prevention ability is also required.

至っていた。For this reason, highly safe animal and vegetable oils, liquid paraffin, and the like have been used as lubricating oils for compressors used in the applications described in 2 above. However, animal and vegetable oils and liquid paraffin have problems with rust prevention and oxidation stability, and currently oils that are highly safe for such equipment and have excellent corrosion resistance, rust prevention, and lubricity are available. Until today, many issues remained unsolved.

するに至った。[Problem to be solved by the invention] In view of the above problems, the present inventors aimed to develop a lubricating oil that is safe for the human body and has excellent lubricity, rust prevention properties, and oxidation stability. As a result of intensive research, it was discovered that a lubricating oil containing a specific compound using liquid paraffin as a base oil satisfies the above conditions, leading to the completion of the present invention.

The object of the present invention is to provide a lubricating oil composition characterized in that it contains % by weight.

以下、本発明の内容を詳細に説明する。Hereinafter, the content of the present invention will be explained in detail.

るため好ましくない。As the saturated fatty acid having 12 to 22 carbon atoms in the present invention, naturally occurring fatty acids may be used, or those obtained by synthesis may be used. Further, it may be a straight chain or a branched chain. Specifically, for example, lauric acid, tridecylic acid, myristic acid, pentadecylic acid, valmitic acid,
Examples include straight chain fatty acids such as heptadecylic acid, stearic acid, nonadecanoic acid, and arachidic acid, branched fatty acids, and mixtures thereof. Among these fatty acids, those having 14, 16, 18 or 2 carbon atoms, or a mixture of two or more thereof are preferably used. Note that it is not preferable to use a saturated fatty acid or an unsaturated fatty acid other than those having 12 to 22 carbon atoms instead of a saturated fatty acid having 12 to 22 carbon atoms because the performance such as oxidation stability and lubricity will be inferior.
