Abstract
The invention discloses a lubricant multifunction complex additive and a preparation method and application, The lubricant multifunction complex additive is added in the lubricant in a dose of 5 percent (weight) to 1 per thousand (weight), the chemical formula of the complex additives is as above, where R <1>, R <2> are hydrocarbon radicals of 4 to 18 carbon atoms; The mole ratio of Type (1) and type (2) compounds is ranging from 1:9 to 9:1, The preparation of the additive is: 1 mole phosphate and 0.1 to 0.9 mole hydrochloride, 0.1 to 0.9 mole benzene triazolam and 1 mole formaldehyde are reacted ranging from 50 DEG C to 120 DEG C for 5 to 15 hours, then reacts with 1 mole sulfur again ranging from 80 DEG C to 150 DEG C for 8 to 12 hours, thus producing the manufactures. The complex additives can be effective in inhibiting the metal from corrosion by the activity sulfur of lubricant, and meanwhile have good extreme pressure and excellent anti-wear performances, rust-proof performancesand thermal oxidation stability performances.
Description
Technical field
The present invention relates to a kind of lubricating oil additive and Preparation method and use.
Background technology
Sulfur-containing additive is owing to have good extreme pressure anti-wear, thermal oxidation stability, in lubricating oil, obtained using widely, the active sulphur that sulfur-containing additive in use produces can produce corrosion to the metallic surface, generally suppress the corrosion of active sulphur to the metallic surface by in lubricating oil, adding metal passivator, because metal passivator and sulfur-containing additive competition metallic surface, thereby reduced the extreme pressure and antiwear behavior of sulfur-containing additive, particularly at high temperature, high pressure, under the long period operational condition, can cause the overwear vt. of metallic surface, be unfavorable for the lubricated of metallic surface.
Summary of the invention
In order to overcome above-mentioned defective, the invention provides a kind of lubricating grease multiple function composite additive and preparation method and application, this lubricating grease multiple function composite additive should integrate extreme pressure, metal deactivation chemical group, have good extreme pressure anti-wear, thermal oxidation stability, rust-preventing characteristic and metal deactivation performance simultaneously, can solve the contradiction that sulfur-containing extreme-pressure additive and metal passivator use simultaneously in lubricant formula, be beneficial to the lubricated of metallic surface.
The present invention for the technical scheme that solves its technical problem and adopt is:
The chemical general formula of this lubricating grease multiple function composite additive is as follows:
R in the formula
1, R
2Alkyl for 4-18 carbon atom; Formula (1) and formula (2) compound compound molar ratio can be from 1: 9 to 9: 1.
Further technical scheme of the present invention is:
In order to guarantee that general formula (1) and (2) compound can dissolve R well in lubricating oil
1, R
2In the summation of carbon atom with 24-66 carbon atom for well.
The preparation method is: the 124 Triazole of 1 mole phosphorous acid ester and 0.1-0.9 mole alkanamine, 0.1-0.9 mole and 1 mole formaldehyde obtained product with 1 mole sulphur in 8-12 hour 80-150 ℃ of reaction again 50-120 ℃ of reaction 5-15 hour.
The application of lubricating grease multiple function composite additive in lubricating oil: when by weight, add-on is 5% to 1 ‰ of a lubricating oil total amount, and optimal addn is 1% to 1 ‰ of a lubricating oil total amount.
The invention has the beneficial effects as follows: the compound of chemical general formula (1), (2) is as lubricating oil additive, not only has good metal deactivation performance, and have extreme pressure and antiwear behavior, antioxidant property and a rustless property, be applied to not only can improve in the lubricating oil antiseptic property of oil product, and can reduce the consumption of extreme pressure anti-wear additives in the lubricating oil, oxidation inhibitor, rust-preventive agent, be beneficial to the lubricated of metallic surface.
