Title:
REFRIGERATING MACHINE OIL COMPOSITION AND ITS PREPARATION METHOD
Document Type and Number:
WIPO Patent Application WO/2009/043218
Kind Code:
A1
Abstract:
The present invention relates to a refrigerator oil composition, it comprises the mixed α-olefin polymer oil as base oil and the additive, the viscosity of the mixed α-olefin polymer oil is less than 6 mm2/s at 40°C and no less than 3 mm2/s at 40°C. The mixed α-olefin polymer oil is C15-C22 mixed isoolefine, C15-C22 mixed isoparaffin, or the mixture of C15-C22 mixed isoolefine and C15-C22 mixed isoparaffin. The refrigerator oil composition provided by this invention has the following merits: (1) the refrigerator oil composition can finely dissolve R600A refrigerant, its flocculation point may reach lower than -70°C; (2) the refrigerator oil composition has fine cold flow property, its pour point may reach lower than -70°C, its kinematic viscosity is less than 500 mm2/s at -40°C; (3) it has obvious energy saving performance, compared with the refrigerator oil which viscosity is 22 mm2/s at 40°C, it can economize on energy 14%, compared with the refrigerator which viscosity is 10 mm2/s at 40°C, it can economize on energy 4%.
