Abstract
The invention discloses a compressor oil composition which comprises the following components in percentage by weight: 0.2-0.6 percent of antioxidant, 0.2-0.8 percent of ashless complexing agent A, 0.2-0.8 percent of ashless complexing agent B, 0.01-0.3 percent of ashless antiwear agent, 0-0.1 percent of anti-foaming agent and the balance of basic oil, wherein the basic oil comprises cut narrow fraction hydrogenated mineral oil and cycloparaffin basic oil. According to the compressor oil composition, the two complexing agents are matched and play a synergic enhancement effect, so that the compressor oil composition has comprehensive, balanced and excellent properties, such as oxidation stability, extreme pressure antiwear property, anti-rust property and demulsification property and is not easy to generate greasy filth; and meanwhile, the basic oil has high dissolubility, excellent low-temperature property and other properties, so that the compressor oil composition has excellent high-temperature oxidation stability, cooling property and extreme pressure antiwear property on the whole, and especially has excellent detergency and dispersancy and greasy filth and carbon deposit resistance property.
Description
Technical field
The present invention relates to a kind of industrial technical field of lubricating oil, particularly relate to a kind of compressor oil composition for lubricate compressors equipment.
Background technology
Compressor is widely used in the industries such as chemical industry, machinery, electronics as a kind of general machinery equipment, and present widely used compressor has reciprocating type, screw and centrifugal.Compressor oil is used for compressor, usually have effects such as lubricated, sealing, cooling and cleaning, the quality of compressor oil oil product has very big influence to compressor work reliability and security, for reciprocation compressor, if compressor oil is second-rate, form carbon deposit at vent valve easily, cause the air valve imprecision, make the pressurized air of High Temperature High Pressure return cylinder, temperature constantly raises after compressing repeatedly, so that produces the hidden danger of blast.For screw-type compressor and centrifugal compression, though there is not the danger of blast, also require the work-ing life of compressor oil longer usually.
For satisfying the environment for use of compressor oil, can in base oil, add oxidation inhibitor, anti-wear agent, rust-preventive agent, ashless dose etc. usually, so that it reaches service requirements, increases the service life.But the oxidation inhibitor of higher amount easily produces the dissolving difficulty, forms sludge, increases the problem that greasy filth generates trend; In the extreme boundary lubrication performance that increases oil product, its stronger polarity easily causes oil oxidation, emulsification, formation corrosion as extreme pressure anti-wear additives; Rust-preventive agent can influence antioxygen, the extreme boundary lubrication of oil product in the rust-preventing characteristic that provides.
As disclosed a kind of air compressor oil composition in the Chinese patent application file of CN 10724489A, it is in polyalphaolefin and the mixed base oil of ester class oil phase, added oxidation inhibitor, the Ashless stain-resistant agent, metal passivator, form behind the added ingredients such as ash-free antiwear agent, kilfoam, it is right because the base oil of this compressor oil is the synthetic oil of plain mineral oil, and the compressor oil of plain mineral oil type is too short work-ing life, be easy to generate carbon deposit, simultaneously, the cost of the compressor oil of synthesis type is higher.
Summary of the invention
The invention provides a kind of compressor oil composition, it has excellent high temperature oxidation stability, cooling property and extreme pressure anti-wear, particularly has excellent detergent-dispersant performance and the characteristic of anti-greasy filth carbon deposit, to improve the oil property of compressor oil on the whole.
Because every performance of lubricating oil mainly determines that by base oil additive just has auxiliary, enhancement.Another main purpose of the present invention is from base oil, by the base oil science being arranged in pairs or groups the whole over-all properties that promotes compressor oil.
For achieving the above object, the present invention proposes a kind of compressor oil composition, and it comprises the following component of counting by weight percentage:
Oxidation inhibitor: 0.2%～0.6%;
Ashless recombiner A:0.2%～0.8%;
Ashless recombiner B:0.2%～0.8%;
Ash-free antiwear agent: 0.01%～0.3%;
Kilfoam: 0～0.1%;
Surplus is base oil, comprises close-cut fraction hydrogenation mineral oil and cycloalkane base oil through cutting.
Wherein, described oxidation inhibitor is the polymer phenol type antioxidant, and it is selected from 2, the 6-ditertbutylparacresol, 2, the 6-di-tert-butylphenol, or any one of thioether phenol.
Described ash-free antiwear agent is selected from the phosphoric acid ester ammonium salt, triphenyl-thiophosphate, curing phosphoric acid salt, or one or more the mixture in the phosphoric acid nonyl amine salt mixture.
Described ashless compressor oil recombiner A is selected from a kind of among commercially available turbine oil recombiner T6001 or the RST6008.
Described ashless compressor oil recombiner B is selected from commercially available recombiner DG6032, a kind of among HQT9802 or the RST6028.
Described ashless recombiner A and ashless recombiner B mass ratio are 1: 1～7.
At least comprise silicone composite in the described kilfoam.
The proportioning of close-cut fraction hydrogenation mineral oil and cycloalkane base oil is 1～5: 1 in the described base oil.
Contained close-cut fraction hydrogenated base oil through cutting in the base oil of the present invention after vacuum distilling, is produced the byproduct of vacuum oil by hydrogenation mineral base oil or naphthenic base oils.This kind oil product fraction is narrow, and good uniformity can not play cigarette, the High Temperature High Pressure better tolerance, and good uniformity, heat radiation cooling performance excellence, high temperature tolerance is strong, and detergent-dispersant performance is good, is difficult for producing the greasy filth carbon distribution.And have good low-temperature fluidity and high temperatrue stability, and naphthenic base oils is to be raw material with the naphthenic base crude, obtains after process fractionation, the refining purification that it has characteristics such as high resolution, low temperature performance excellent.
For reducing pining down mutually between each additive, the present invention selects suitable ashless additive, strict control additive amount meticulously, the proportioning of each agent of fine equilibrium, and ashless recombiner A and the composite use of ashless recombiner B can be played collaborative stiffening effect, make that oil product has comprehensively, performances such as balance, excellent oxidation stability, extreme pressure anti-wear, rust-preventing characteristic, breakdown of emulsion, and be difficult for producing greasy filth.
Compared with prior art, the invention has the beneficial effects as follows: compressor oil composition of the present invention has excellent high temperature oxidation stability, cooling property, extreme pressure anti-wear, particularly has excellent detergent-dispersant performance and anti-greasy filth carbon deposit characteristic.
