Abstract
The present invention relates to a kind of air compressor oil forms.This compressor oil is made up of base oil, oxidation inhibitor, rust-preventive agent, and oxidation inhibitor comprises alpha-naphthylamine, 2,6-ditertbutylparacresol and thiophosphoric acid amine oxidation inhibitor, and rust-preventive agent is dodecenylsuccinic acid.This compressor oil use properties is good, and the carbon deposit tendency is little, and preparation is simple, and cost is low.
Description
The present invention relates to a kind of lubricating oil and form, specifically is that air compressor oil is formed.
By literature search as can be known, although air compressor oil external and domestic application can satisfy service requirements at present, but exist additive wide in variety, big with dosage, particularly contain metal oxidation inhibitor in the prescription, the resistance to emulsion of metal is had problems such as detrimentally affect, simultaneously because of carbon residue height behind the oil oxidation, must select the base oil of deep refining for use, thereby the cost of oil product is higher.
It is good to the objective of the invention is to develop a kind of antioxidant property, and the carbon deposit tendency is little in the use, and the compressor oil that cost is low is formed.
Air compressor oil of the present invention is that the neutral oil of paraffinic crude after atmospheric and vacuum distillation, solvent dewaxing, solvent treatment is base oil, and basic oil properties sees Table 1.
Can access the base oil of different viscosity grade respectively with the various fraction oil of different ratios, the blend ratio that base oil is suitable sees Table 2.40 ℃ of kinematic viscosity of blending back base oil are 30.00～150.00mm
2/ s, viscosity index 97～107.
Because reciprocating air compressor oil is directly to contact with air under high temperature (the highest about 200 ℃) and high pressure, be easy to oxidized, and the iron of compressor, the weathering process that the katalysis on copper surface and the existence of water have more aggravated oil product, so must add oxidation inhibitor, rust-preventive agent etc. in the compressor oil.Compressor oil of the present invention consists of in the 100g base oil, adds oxidation inhibitor alpha-naphthylamine 0.1～0.3g, 2.6-ditertbutylparacresol 0.2～0.4g, and rust-preventive agent laurylene base fourth=acid 0.03～0.07g also adds a kind of molecular structure in addition and is
Thiophosphoric acid amine oxidation inhibitor 0.003～0.008g, R wherein
1, R
2, R
3Be respectively 4-8 C alkyl, X=H-, C
12H
25=NH
3-or
, this oxidation inhibitor molecular-weight average is 500～800.
The preparation method of compressor oil of the present invention is added to oxidation inhibitor, rust-preventive agent in the base oil by a certain percentage, and stirring under 70 ℃ of temperature gets final product.
Compressor oil of the present invention always significantly reduces with dosage because to select neutral oil for use be base oil and selected novel antioxidant for use, thereby economic benefit obviously improves, and use properties is good simultaneously, and the carbon deposit tendency is little in actual the use.
With an embodiment advantage of the present invention is described below, the ratio of components of present embodiment is: neutral oil 100g, 2.6-ditertbutylparacresol 0.35g, alpha-naphthylamine 0.15g, dodecenylsuccinic acid 0.08g, thiophosphoric acid amine (Jinling Petrochemical Co.'s chemical industry one factory product) 0.05g, the salient features of the compressor oil of this composition obviously is better than the compressor oil A that Petro-Chemical Corporation's signing is passed through, and sees table 3 for details.
Present embodiment compressor oil and compressor oil A economic benefit relatively see Table 4.
Kinematic viscosity behind the present embodiment compressor oil real machine test, copper corrosion, resistance to emulsion, rust-preventing characteristic, oxidation stability, distillation performance and resistance to abrasion have no significant change, and analytical data sees Table 5.
