Abstract

The invention provides a synthetic ester refrigerator oil composition. The synthetic ester refrigerator oil composition comprises, by weight, 100.0 parts of synthetic ester base oil, 0.01-50.0 parts of other base oil, 0.5-10.0 parts of an anti-wear agent, 0.5-3.0 parts of an oxidation and corrosion inhibitor, 0.2-1.0 part of a multifunctional anti-wear, antifriction and energy saving additive, 0.1-0.5 parts of a metal deactivator, and 0.0001-0.01 parts of an antifoaming agent. The synthetic ester refrigerator oil composition can meet performance requirements of the viscosity grades of GB / T16630-2012 refrigerator oil of 7, 10, 15, 22, 32, 46, 68 and 100.

Description

technical field [0001] The invention relates to a refrigerating machine oil composition, which is especially suitable for lubricating the refrigerating compression system of hydrocarbon hydrocarbon refrigerants. Background technique [0002] With the strengthening of environmental protection awareness, the choice of refrigerants in the refrigeration industry is increasingly inclined to environmentally friendly hydrocarbon refrigerants. The previously widely used chlorofluorocarbon refrigerants have gradually been eliminated due to the destruction of the atmospheric ozone layer. Although the damage rate of hydrofluorocarbons to the ozone layer is zero, it is gradually restricted due to the high global warming coefficient of more than 1,000. Hydrocarbon refrigerants that do not contain chlorine and fluorine elements have become the new darling of the refrigeration industry. Therefore, it is imperative to develop refrigerating machine oil with excellent compatibility with hydr...
