Abstract
The invention discloses a lubricant combination for a universal polyether refrigerator. The lubricant combination is characterized by adopting polyether as base oil and being cooperated with various composite additives including an antioxidant, a metal deactivator, an extreme pressure agent, an anti-wear agent, an anti-foaming agent, an anti-emulsifying agent, an acid capture agent and an anti-glue agent. The lubricant combination disclosed by the invention is good in thermal chemical stability and compatibility when being in contact with a refrigerant, proper in viscosity, good in viscosity-temperature property, good in lubricating property and low-temperature fluidity, lower in moisture content and excellent in electrical insulation property.
Description
Technical field
The invention belongs to refrigerator compressor lubricant field, particularly universal polyethers refrigerator compressor lubricant composition.
Background technology
Polyethers (PIG) is unique synthetic lubricant, because its high oxygen level is polar solvent, it also has various dissolution characteristics, be widely used in the occasion that petroleum products has carbon deposit and greasy filth besides the cleaning.Compared with the petroleum lubricant of same viscosity, it has: lower pour point, low-steam pressure, low ash content and metal content, distinctive cloud point.The more important thing is, polyethers is owing to itself having higher stability, add that molecular structure can adjust, good adaptability is had to multiple refrigeration agent, this just extends the range of application of butyl ether as synthesis refrigerator compressor lubricant, by the research of additive formulations and perfect, it is made likely to be applied to multiple refrigeration agent.
And the functional requirement of refrigerator to lubricant has: lubricate compressors surface of friction, reduce friction function, prevent wearing and tearing, take away compression and fricative heat, and seal at piston (rotor) and cylinder and compressor shaft gland place, prevent leakage of refrigerant.And performance requriements has: have good thermo-chemical stability and consistency with refrigerant contact, suitable viscosity and good viscosity-temperature characteristics, low water content and excellent electrical insulation capability, good oilness and low-temperature fluidity.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of have have good thermo-chemical stability and consistency with refrigerant contact, suitable viscosity and good viscosity-temperature characteristics, good oilness and low-temperature fluidity, the universal polyethers refrigerator compressor lubricant composition of lower water content and excellent electrical insulation capability.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
Universal polyethers refrigerator compressor lubricant composition, adopt oil based on polyethers, coordinate multiple composite additive, its each component and mass percent thereof are:
| Component | Mass percent content |

| Metal passivator | 0.3％～0.4％ |
| Extreme pressure agent | 1.0％～2.0％ |
| Anti-wear agent | 2.0％～3.0％ |
| Kilfoam | 30～40ppm |
| Non-emulsifying agent | 0.06％～0.08％ |
| Acid trapping agent | 0.1％～0.3％ |
| Antigum inhibitor | 0.1％～0.3％ |
Oxidation inhibitor is the polypropylene glycol monobutyl ether of mass ratio 67% and the 2,6 ditertiary butyl p cresol compound of 33%.
Metal passivator is the thiadiazole of mass ratio 50% and the 124 Triazole derivative compound of 50%.
Extreme pressure agent is alkyl phosphite.
Anti-wear agent is phosphonothionic acid phenyl ester.
Kilfoam is polymethylphenyl siloxane fluid.
Non-emulsifying agent is amine and epoxide condenses.
Acid trapping agent is alkenyl succinic acid half ester.
Antigum inhibitor is butyl octyl pentanoic.
The remarkable advantage of universal polyethers refrigerator compressor lubricant composition of the present invention has: have good thermo-chemical stability and consistency with refrigerant contact, suitable viscosity and good viscosity-temperature characteristics, lower water content and excellent electrical insulation capability.
