Title:
Refrigerating machine oil composition
Document Type and Number:
Japanese Patent JPWO9611246
Kind Code:
A1
Abstract:
There is disclosed a refrigerating machine oil composition which comprises, in the form of a blend, a base oil comprising a mineral oil or a synthetic oil and at least one species selected from the group consisting of a metallic salt of an inorganic phosphoric acid, e.g. potassium phosphate, an amine salt of an inorganic phosphoric acid, e.g. octylamine phosphate, a metallic salt of an organic phosphoric acid, e.g. dipotassium lauryl phosphate, an amine salt of an organic phosphoric acid, e.g. monooctylamine dioleyl phosphate, a metallic salt of an organic phosphonic acid, e.g. dipotassium oleyl phosphonate, an amine salt of an organic phosphonic acid, e.g. octylamine dilauryl phosphonate, a metallic salt of an organic phosphorous acid, e.g. sodium dioleyl phoshite, and an amine salt of an organic phosphorous acid, e.g. octylamene dioleyl phosphite. The refrigerating machine oil composition according to the present invention has excellent lubricating performance, enhances lubricity between an aluminum material and steel material, can suppress seizure and wear therebetween, does not bring about environmental pollution and thus is well suited as the lubricating oil for a refrigerating machine using, as the refrigerant, a hydrogen-containing Flon compound such as R134a.
