Description
Technical field
The present invention relates to a kind of lubricating oil, particularly a kind of super cryogen that is used for screw air compressor.
Background technology
In the operational process of screw air compressor, lubricating oil contacts for a long time with air under High Temperature High Pressure, and the high-temperature thermal oxidation performance of compressor oil, corrosion resistance etc. have been proposed very high requirement.Existing air compressor oil is difficult to satisfy the life-time service of screw air compressor at aspects such as thermal oxidation stabilities.
It is the preparation method of the synthetic air compressor oil of base oil with aromatic ester and polyolefine that Chinese invention patent (CN1702159A) discloses a kind of, because the viscosity index of aromatic ester and polyolefin base oil itself is not high, at high temperature oil viscosity reduces very fast.
It is base oil with mineral oil that Chinese invention patent (CN 1077216A) discloses a kind of, the preparation method who contains the compressor oil of oxidation inhibitor, rust-preventive agent, this oil is mainly used in reciprocating compressor, because base oil performance limitations, the viscosity index of oil product is not high, and the high-temperature oxidation resistant corrosive nature is difficult to satisfy the life-time service of screw air compressor.
Summary of the invention
The object of the present invention is to provide a kind of viscosity index height, temperature of solidification is low, high-temperature oxidation resistance is good screw type air compressor super cryogen.
The object of the present invention is achieved like this: a kind of screw type air compressor super cryogen, the component and the content (weight ratio) that it is characterized in that A, super cryogen: high-temperature antioxidant 1-5%, extreme pressure anti-wear additives 1-5%, corrosion inhibitor 0.01-0.5%, rust-preventive agent 0.01-0.5%, surplus is a base oil, the component of B, base oil and content (weight ratio): polyethers 20-80%, polyol ester 80-20%.
Described polyethers is 40-400cst 40 ℃ of viscosity.
Described polyol ester is 10-100cst 40 ℃ of viscosity.
Described high-temperature antioxidant is at least a in alkyl diphenylamine, phenyl αNai An, sulphur naphthazin(e) and the Hinered phenols antioxidant.
Described extreme pressure anti-wear additives is at least a in tritolyl phosphate, phosphorous acid ester, phosphate amine salt and the thiophosphatephosphorothioate.
Described corrosion inhibitor is the 124 Triazole type;
Described rust-preventive agent is the Ashless stain-resistant agent.
Polyethers has many premium propertiess, good lubricity, high flash point and high viscosity index (HVI), low volatility and low pour point, very little to the effect of metal and rubber, at high temperature use, the oxidation products that is generated is dissolved in the last liquid fully, perhaps vapor away fully, do not stay settling, good heat conductivity in the equipment.Polyol ester (ester class oil) has good high-temperature thermal oxidation stability, good low-temperature fluidity and oilness.
The present invention adopts the base oil of polyethers and polyol ester mixed preparing, and its high temperature performance is good, viscosity index height, excellent performances such as oilness and heat conductivity.Be equipped with additives such as efficient oxidation and corrosion inhibitor, extreme pressure anti-wear additives and sanitas again, formed the special-purpose super cryogen of screw air compressor.
Characteristics of the present invention are: have very high viscosity index and very low temperature of solidification, oil product has good high-temperature oxidation resistant, anticorrosive, extreme-pressure anti-wear, antiseptic property, and the long service life of lubricating oil reduces servicing time of equipment.Under high use temperature, still can keep certain oil film strength, avoid metal to-metal contact; The good heat transfer property of oil product helps the cooling of screw rod, reduces service temperature.
