Refrigerator oil

Abstract

The present invention provides a refrigerator oil containing a base oil, a compound represented by general formula (1), and an epoxy compound. [In formula (1), R1 and R2 each independently represent a monovalent hydrocarbon group, R3 represents a divalent hydrocarbon group, and R4 represents a hydrogen atom or a monovalent hydrocarbon group.]

Description

technical field [0001] The invention relates to a refrigerating machine oil. Background technique [0002] In general, lubricating oil is used to ensure the lubricity of mechanical elements such as sliding parts. In addition, lubricating oils contain base oils such as mineral oils and synthetic oils, and additives added to the base oils according to desired characteristics. As such an additive, for example, an antiwear agent for the purpose of preventing wear of the sliding part can be used. [0003] However, lubricating oils may require specific properties depending on their usage, and therefore the types of additives that can be used differ depending on the usage of the lubricating oil. For example, as described in Patent Document 1, in lubricating oil for refrigerating machines (refrigerating machine oil), adding an antiwear agent to the refrigerating machine oil may cause problems such as capillary clogging depending on conditions. Therefore, in the field of refrigera...
