Abstract
The invention relates to a refrigerating machine oil composition, comprising polyol ester, semi-hindered phenol type antioxidant, antiwear agent, metal deactivator and acid catcher; wherein the polyol ester is ester product of reaction of pentaerythritol with mixture of isononanoic acid and diethyl hexanoic acid. The refrigerating machine oil composition provided by the invention has good oxidation stability, and oxidation induction period thereof is obviously prolonged compared with the refrigerating machine oil utilizing conventional antioxidant.
Description
Technical field
The present invention relates to a kind of refrigerated machine oil composition.
Background technology
Widely used in the past CFCs, HCFC refrigeration agent chemicalstability are good; Leak into and be difficult in the air decomposing in the troposphere; In case when entering into the stratosphere at ozonosphere place, under the irradiation of short wave ultraviolet, can decomposite chlorine radical, participate in the consumption of ozone through general circulation; Ozonosphere in the atmosphere is produced destruction, replaced at present by not chloride hydrogen fluorohydrocarbon (HFCs) refrigeration agent.
Synthetic ester (POE) has good mutual solubility, stability and material compatibility, and the reliable and safety of lubricity, environmental protection have become the first-selected lubricating oil of hydrogen fluorohydrocarbon (HFCs) type material.
Different with general lubricating oil; Refrigerator oil is with refrigeration agent circulation continuously between the vaporizer of the compressor outlet of high-temperature zone and cold zone; Its operating temperature range very wide and with the same life-span of compressor; Therefore for refrigerator oil, except should having good lubricated, sealing, cooling and antiseptic property, oxidation stability is even more important.
One of approach that improves the oil product life-span is to add oxidation inhibitor.The kind of oxidation inhibitor is a lot, mainly comprises phenol type, amine type, phenolic ester type, monothioester type, phosphite type etc.Among them, the hindered phenol type antioxidants are widely used refrigerating machine oil, for example, Patent Publication 2001-226690, CN1135594A, CN1157848A, CN1836030A, CN1930276A, CN101018844A are measured using a hindered phenol-based antioxidant antioxidant.But,, therefore adopt general hindered phenol type antioxidant possibly be difficult to satisfy the stable and long lifetime requirement of oxidation owing to compressor operating pressure and the working temperature with the fluoroether refrigerant coupling all will be higher than former compressor.CN1235191A has adopted the sulfur-bearing phenol type antioxidant, and its antioxidant property is not outstanding.
Compare with hindered phenol type antioxidant, the imparity hindered phenol is two different substituting groups at the hydroxyl ortho position.For with half hindered phenol type antioxidant as one of main oxidation inhibitor of refrigerator oil, still do not have bibliographical information both at home and abroad.
Summary of the invention
The technical problem that the present invention will solve provides a kind of refrigerated machine oil composition, and said composition has good oxidative stability.
Refrigerated machine oil composition provided by the invention is 100% in the weight of polyol ester, comprising:
