- the lubricating oil of the present embodiment is a mineral or a metallic material in addition to the base oil.
- the base oil may be naturally produced using various commercially available lubricating oils, or may be artificially synthesized. However, when mixing other types of oils that it is desirable to disperse the mineral, metallic and ceramic powders to be added well, compatibility with these oils is also required. Ester oils are preferred. Specifically, there is a refrigerating machine oil “Icematic” manufactured by Castrol.
- Mineral powders include various clays and ores such as quartz (including quartz).
- clays such as kaolinite, halloysite, montmorillonite, illite (fine muscovite), vermiculite, and the like. Of these, good results have been obtained particularly when kaolinite is used.
- the mineral powder may be naturally produced or artificially synthesized. Only one kind of clay may be added to the base oil, or a plurality of kinds may be added. The same applies to ores. Moreover, you may make it add both clays and ores. More preferably, at least one kind of clay is added.
- These mineral powders have excellent confidentiality / coldness with the inner surface of a machine such as a compressor, and maintain and / or enhance the compression effect of the lubricating oil. Clays also have the effect of reducing friction.
- the metallic powder includes various metal materials and alloy materials.
- metal materials include aluminum, titanium, vanadium, chromium, manganese, cobalt, nickel, copper, lead, gallium, germanium, arsenic, selenium, gold, platinum, silver, bismuth, and antimony.
- alloy material include a copper-nickel alloy, a nickel-zinc alloy, a nickel-titanium alloy, and a copper-zinc-aluminum alloy. Of these, it is particularly advantageous from the viewpoint of flexibility to use-nickel nickel copper or alloys thereof. is there. Only one of the metal powders may be added to the base oil, or two or more metal powders may be added to the base oil! /. Machines such as compressors often use metal materials, but metallic powders are easy to be familiar with the inner surfaces of these machines and have the effect of reducing wear.
- Ceramic powders may be used as well.
- two or more kinds of ceramic powders may be added to the base oil.
- the particle size of each additive powder is preferably about 0.1 to 30 ⁇ m, more preferably 0.5 to 10 ⁇ m. If the particle size is too large, friction may increase or clogging may occur inside the machine, which may impair lubrication performance. On the other hand, if the particle size is smaller than necessary, the desired friction reduction and cooling effect cannot be obtained.
- the mineral powder, metallic powder, and ceramic powder need not necessarily have the same particle size, and may have different particle sizes.
- the hardness of the additive powder is preferably 2 to 7 in terms of Mohs hardness. If the Mohs hardness is less than 2, it does not act as a powder. If the Mohs hardness is greater than 7, the inner surface of the machine will be scratched.
- the addition ratio of the mineral, metallic and ceramic powders to the base oil is preferably 0.02 to 2.5 parts by weight of the additive powder to 100 parts by weight of the base oil. If the ratio of the additive powder to the base oil is too small, it will not function as an additive powder. Conversely, if it is too large, the function as a lubricating oil will be impaired.
- the mineral powders are added in an amount of 200 to 1500 parts by weight, preferably 500 to 800 parts by weight, based on 100 parts by weight of the metal. To do. By using such a composition, it is possible to efficiently bring out both performances of reducing friction and improving cooling effect.
- the ceramic powder is added in place of a part of the metallic powder.
