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 polyisobutene amine and polyether mixture amine detergent into the mixing tank, keep the temperature of the tank between 40 and 50 °C, and continuously stir for 2 Hours until the mixture is completely dissolved and becomes 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) 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 20 parts of polyisobutylene amine and polyether mixture amine detergent into the mixing tank, keep the temperature of the tank 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 an additive composite of lubricating oil for industrial gears, in particular to an additive composite of lubricating oil for a gear transmission system, belonging to the technical field of additive for lubricating oil. The additive composite comprises the following components by mass percentage: 48% to 80% of sulfur-containing extreme-pressure anti-wear agent, 10% to 35% of phosphorus-containing anti-wear agent, 1% to 10% of metal deactivator, 5% to 20% of detergent and 2% to 5% of anti-rust agent, wherein the sum of the mass percentages of the components is equal to 100%. By substituting the amine mixture of poly-isobutene amine and polyether as detergent commonly used in the existing gasoline detergent for the detergent based on polyisobutylene succinimide, basic calcium sulfonate and basic magnesium sulfonate, which is used in the conventional additive for lubricating oil, the additive composite of the invention can obviously improve the anti-emulsification capacity of the lubricating oil for the industrial gears.
