Problems solved by technology

[0002] At present, due to changes in refining processes and raw materials, the quality of base oils has become increasingly unstable, which poses a severe challenge to lubricating oil manufacturers and additive suppliers. As a lubricating oil additive, since polyisobutylene succinimide and basic calcium sulfonate, magnesium detergent and dispersant are used as detergent and dispersants, the phenomenon of unqualified anti-emulsification performance often occurs when base oil is blended. Therefore, the development It is of great significance to develop an additive composition with broad-spectrum base oil adaptability

Embodiment 1

[0012] Add 65 parts of sulfurized isobutylene (T321) extreme pressure antiwear agent into the enamel mixing kettle with agitator, then add 15 parts of phosphorothioate and its amine salt derivatives (T307) antiwear agent, 2 parts of alkenyl Add succinate (T747) and 1 part of dinonyl naphthalene sulfonate barium salt (T705) rust inhibitor into the blending kettle, keep the temperature of the kettle between 60 and 70°C, and stir continuously for 4 hours; finally, Add 2 parts of thiadiazole derivatives (T561) metal deactivator and 15 parts of Mannich amine detergent into the blending kettle, keep the temperature of the kettle between 40 and 50°C, and stir continuously for 2 hours until the mixture All dissolved and uniformly transparent.

Embodiment 2

[0014] Add 60 parts of sulfurized isobutylene (T321) extreme pressure antiwear agent into the enamel mixing kettle with agitator, then add 15 parts of phosphorothioate and its amine salt derivatives (T307) antiwear agent, 2 parts of alkenyl Add succinate (T747) and 1 part of dinonyl naphthalene sulfonate barium salt (T705) antirust agent into the blending kettle, keep the temperature of the kettle between 6°C and 70°C, and stir continuously for 4 hours; Finally, add 2 parts of thiadiazole derivatives (T561) metal deactivator and 20 parts of Mannich amine detergent into the blending kettle, keep the temperature of the kettle between 40 and 50°C, and continuously stir for 2 hours. Until the mixture is completely dissolved and becomes uniformly transparent.

Abstract

The invention relates to a gear oil additive compound with excellent demulsification performance, which is a lubricating oil additive compound for a gear transmission system and belongs to the technical field of lubricating oil additives. The gear oil additive compound comprises the following raw materials by mass percent: 48-80 percent of sulphureous EP antiwear agent, 10-35 percent of phosphorous antiwear angent, 1-10 percent of metal deactivator, 5-20 percent of detergent and 2-5 percent of antirusting agent, wherein the percent sum of the raw materials is 100 percent. In the additive compound, mannich amine detergent which is normally used in the existing gasoline detergent is utilized to replace polyisobutylene succinimide, alkaline sulfoacid calcium and magnesium detergent which are used in traditional lubricating oil additives, thereby the demulsification performance of industrial gear lubricating oil is remarkably improved.
