に使用する冷凍機油には、摩擦を低減しかつ厳しい使用
条件に耐える極圧性を有することが要求される。3.1/ Conventional technology Compressors used in refrigerators, air conditioners, etc. are becoming smaller and more efficient, and usage conditions are becoming stricter. Therefore, the refrigerating machine oil used therein is required to have extreme pressure properties that reduce friction and withstand severe usage conditions.
そこで、摩擦低減と極圧性向上のだめ、鉱油系及び合成
油系冷凍機油には従来、トリクレジルホスフェートで代
表されるアルキルリン酸エステル、有機モリブテン化合
物、パーフロロポリエーテル誘導体等を配合する提案が
なされてきた。Therefore, in order to reduce friction and improve extreme pressure properties, it has been proposed to add alkyl phosphates such as tricresyl phosphate, organic molybdenum compounds, perfluoropolyether derivatives, etc. to mineral oil-based and synthetic refrigeration machine oils. It has been done.

加剤が重重れていた。Problems to be Solved by the Invention However, in the above-mentioned refrigerating machine oil, the effects cannot be obtained unless a large amount of alkyl phosphate esters, organic molybdenum compounds, etc., which are highly compatible with the oil, are added.
Highly effective fluorine compounds such as perfluoropolyether derivatives have low compatibility with oil and separate even at room temperature.
Old materials may be present in the system, causing piping to become clogged, etc.
In neither case has the desired effect been obtained. Therefore, in order to obtain a sufficient effect with as little addition as possible, additives that have a large effect of reducing friction and improving extreme pressure properties and are highly compatible with the base oil have been heavily used.
本発明は上記課題に鑑み、基油との相溶性の高い添加剤
を配合することによって、摩擦を低減し、かつ極圧性を
大幅に向上した冷凍機油を得るものである。In view of the above problems, the present invention provides a refrigerating machine oil that reduces friction and significantly improves extreme pressure properties by blending additives that are highly compatible with the base oil.

低減効果大で極圧剤としての機能も大きい。Function The compound contained in the refrigerating machine oil of the present invention has an aliphatic hydrocarbon end, a fluorinated hydrocarbon end, and a polar group in its molecule, and the surface tension decreases due to the influence of the fluorinated hydrocarbon. Since it has a lower resistance to oil (approximately 4° dyn/crr of mineral oil, 20 to 25 dyn/z), this compound selectively adsorbs polar groups toward the sliding surface and absorbs fat. Since group hydrocarbons and hepta-hydrocarbons are oriented outward, even when added in small amounts, it has a great effect of reducing friction on sliding surfaces and has a great function as an extreme pressure agent.

Evaluation was made at the lower limit temperature (saturated dissolution temperature) at which a predetermined content of additives dissolves in dissolved refrigerating machine oil. Here, the reason why 5 wt % of fluorocarbon was dissolved in the refrigerating machine oil to evaluate the compatibility was to approximate the state in the refrigerating machine system.

30 straight-chain or branched saturated or unsaturated aliphatic hydrocarbon groups are suitable; if the carbon number is 13 or less, it is difficult to obtain a significant improvement in lubricating performance compared to base oil alone;
Above this, it is difficult to obtain the effect of improving the affinity with the fluorocarbon refrigerant.
