Embodiment 1-5

[0029] The raw material ratio of the lubricating oil additives with anti-oxidation, anti-wear and anti-rust functions of each embodiment is shown in Table 1 below. The preparation method is as follows: stir and mix all raw materials in a container under normal pressure and 45-80 ° C. Yes, wherein, the base number of calcium monoalkylbenzenesulfonate is controlled at 0-6mgKOH / g, and the carbon number of the side chain alkyl group is between 18-30. After testing the base number of the lubricating oil additives in various embodiments of the present invention ≥50mgKOH / g, calcium content ≥1.2wt%, sulfur content ≥0.85wt%, phosphorus content ≥0.5wt%, nitrogen content ≥1.8wt%;

[0031]

Embodiment 6

[0033] The amount of raw materials added and the selection of types are basically the same as in Example 5 of the present invention, except that the alkylbenzene sulfonate is a mixture of calcium monoalkylbenzenesulfonate and barium monoalkylbenzenesulfonate, and there is no definite amount between the two Limit, and during the preparation process, the mixing and stirring rate is controlled at 100 rad / min, the stirring time is controlled at more than 30 min, and the stirring temperature is controlled at 80°C.

Embodiment 7

[0035] Raw material addition amount and type selection are basically consistent with embodiment 5 of the present invention, only the carbon number of the alkyl group of high alkali value sulfurized alkylphenate calcium is controlled between 12-15, and in the preparation process, the speed control of mixing and stirring At 200rad / min, the stirring time was controlled at 50min, and the stirring temperature was controlled at 80°C.

Abstract

The invention provides a lubricant additive with antioxidant, antiwear and rustproof functions. The lubricant additive with the antioxidant, antiwear and rustproof functions is mainly prepared from the following raw material components in parts by mass: 10-60 parts of alkylbenzene sulfonate, 30-60 parts of alkyl diphenylamine, 20-40 parts of isopropyl beta-(3,5-ditertbutyl-4-hydroxy phenyl) propionate, 10-30 parts of methylene-bis-alkyl dithiocarbamate, 10-30 parts of a sulfur-phosphorus-nitrogen type extreme pressure agent and 5-20 parts of a sulfurized calcium phenate type high temperature clearing agent. A preparation method of the lubricant additive with the antioxidant, antiwear and rustproof functions comprises the following steps: mixing all the raw materials and uniformly stirring, so that the lubricant additive with the antioxidant, antiwear and rustproof functions is obtained. The lubricant additive of the embodiment of the invention is well applied to engine lubricant, hydraulic oil, gear lubricant, steam turbine lubricant and compressor lubricant, is respectively excellent in the antioxidant, antiwear and rustproof aspects and also has excellent clearing function, functionality of the lubricant additive can not be reduced no matter at high temperature or low temperature, and some properties or a certain property of lubricant can be obviously improved.

Description

technical field [0001] The invention relates to the field of fine petrochemical industry and the field of preparation of lubricating oil additives, in particular to a lubricating oil additive with anti-oxidation, anti-wear and anti-rust functions, its preparation method and application. Background technique [0002] The operation of equipment is inseparable from lubricating oil additives, and lubricating oil cannot be separated from lubricating oil additives. Lubricating oil additives are the essence of various modern high-grade lubricating oils. According to statistics, about 30% of energy consumption is on friction, and 80% of damaged parts are scrapped by wear and tear. Therefore, improving lubricating performance to reduce friction, wear and prevent sintering is of great significance to the national economy. The most commonly used additives in lubricating oils are extreme pressure anti-wear additives, which are used to improve the tribological properties of base oils un...
