Abstract
The invention relates to a turbine lubricating oil antioxidant additive, which is basically characterized by being composed of the following components in percentage by weight: 25-27% of sterically hindered phenol, 25-27% of diarylamine, 4-5% of imidazoline derivative, 4-5% of polyacrylate, 3-4% of benzotriazole, 4-5% of alkyl phosphate ester and salt, 3-4% of polyalkoxy polyamine, 2-3% of metal magnesium powder and the balance of base oil. The preparation method of the antioxidant additive is simple; the prepared product has the price lower than that of international similar products and the efficacy higher than that of other same-functional products; and both the sterically hindered phenol and diarylamine are simultaneously used as antioxidants in the lubricating oil additive, thus the antioxidation in the lubricating oil can be exerted for a longer time, the use period of the lubricating oil is prolonged, and the antioxidation and comprehensive efficacies of the lubricating oil are improved.
Description
(1) technical field
The present invention relates to a kind of oil dope, particularly a kind of preparation scheme and preparation method of turbine lube oil antioxidant additive.
(2) background technology:
In turbine oil, oxidation inhibitor mainly is used for suppressing the attack of oxygen to turbine oil, and reduces disadvantageous oxide compound generation, like the formation of corrodibility organic acid and insoluble greasy filth.Along with human sciences's progress, the performance of turbine oil is also had higher requirement.Turbo should have following effect with oil:
1. the generation of anti-oxidant and anti-greasy filth.
2. anti-the foaming.
3. can be fast with oil and water sepn.
4. stop corrosion.
5. the effect that can serve as hydraulic liquid.
6. walk heat through tape loop.
And current turbine oil antioxidant additive, matter is measured, costs an arm and a leg.Low price, quality and effect are all undesirable.The oxidation inhibitor that has is difficult to reach effect steady in a long-term.
(3) summary of the invention
The objective of the invention is provides a kind of preparation scheme science to the problem that exists in the above-mentioned technology, and the preparation method is simple; Price is low; Quality is high, and effect is permanent, promotes anticorrosive, the anti-foaming simultaneously oxidation resistant; And can be fast with water and the comprehensive effect of each item such as separating of oil, prolong the lubricating oil turbine oil antioxidant addn in work-ing life.
Technical scheme of the present invention:
A kind of turbine lube oil antioxidant additive, essential characteristic is: by base oil; Sterically hindered phenol; Diaryl-amine; Mi Zuo Lin verivate; Polyacrylic ester; Benzotriazole; Alkyl phosphoric acid fat and salt; Gather the alkoxyl group polyamine; Metal magnesium powder is formed; The weight percent of each component is: sterically hindered phenol 25-27%; Diaryl-amine 25-27%; Mi Zuo Lin verivate 4-5%; Polyacrylic ester 4-5%; Benzotriazole 3-4%; Alkyl phosphoric acid fat and salt 4-5%; Gather alkoxyl group polyamine 3-4%; Metal magnesium powder 2-3%.Surplus is a base oil.
A kind of above-mentioned turbine lube oil antioxidant additive, essential characteristic is: base oil is 150BS, 5 centistokes, 10 centistokes, M14, any two kinds of components of 500SN or three kinds of component combinations, the weight quota of two kinds of components or three kinds of components is 1: 1 or 1: 1: 1.Also can be by 150BS and 32#, 46#, 68#, subtract any one component combination in four lines, the weight quota of two components is 6: 4.
A kind of above-mentioned turbine lube oil antioxidant additive, essential characteristic is: metal magnesium powder is a nanoscale powder material, mean particle size is 25-35nm.
A kind of above-mentioned turbine lube oil antioxidant additive, essential characteristic is: with base oil; Sterically hindered phenol; Diaryl-amine; Mi Zuo Lin verivate; Polyacrylic ester; Benzotriazole; Alkyl phosphoric acid fat and salt; Gather the alkoxyl group polyamine; Metal magnesium powder should add the metering of weight per-cent by each component, mixes, and heating also, controlled temperature stirred 120-240 minute between 50-70 ℃.Promptly go out product after the filtration.
Advantage of the present invention: preparation method of the present invention is simple; The product price that makes is lower than international like product; And effect is higher than other congenerous products; Sterically hindered phenol is oxidation inhibitor in the effect of two kinds of components of diaryl-amine in oil dope, but both the time use and more can bring into play its antioxygenation in lubricating oil for a long time.Prolong the life cycle of lubricating oil simultaneously.And oxidation resistant other the comprehensive effects that promote lubricating oil simultaneously of lubricating oil can promoted.
