Abstract

본 발명은 수평균분자량(Mn)이 200~5,000이고 동점도가 100℃에서 2~100cSt인 카복실산 에스테르 또는 수평균분자량(Mn)이 200~5,000이고, 동점도가 100℃에서 2~100cSt인 탄산 에스테르 100중량부와, 플루오로알킬기 함유 알코올 0.001~15중량부로 구성된 것이 특징인 냉동기용 윤활유 조성물에 관한 것이다. 상기 냉도이용 윤활유 조성물은 특히 R-134a와 같은 수소화 플루오로카본(HFC)을 냉매로서 사용하는 압축식 냉동기의 접동부의 금속마모량을 대폭 감소시키는 것이 가능하다. 또한 이 조성물은 윤활유 특성이 우수하므로 압축식 이외의 형식이 냉동기에 대해서도 사용가능하다.The present invention relates to a carboxylic acid ester having a number average molecular weight (Mn) of 200 to 5,000 and having a kinematic viscosity of 2 to 100 cSt at 100 ° C, or a carbonic acid ester having a number average molecular weight (Mn) of 200 to 5,000 and a kinematic viscosity of 2 to 100 cSt at 100 ° C. It is related with the lubricating oil composition for refrigerators characterized by consisting of a weight part and 0.001-15 weight part of fluoroalkyl group containing alcohols. The cold lubricating oil composition can significantly reduce the amount of metal wear of the sliding portion of a compression type refrigerator, in particular using a hydrogenated fluorocarbon (HFC) such as R-134a as a refrigerant. In addition, the composition is excellent in lubricating oil properties, so a type other than a compression type can be used for a refrigerator.
