Abstract

The invention discloses a high-temperature-resistant precipitation antagonist, which belongs to the technical field of lubricating oil preparation. The high-temperature-resistant precipitation antagonist is characterized by being prepared from the following raw materials in parts by weight: 3-5 parts of 2, 6-di-tert-butyl-p-cresol, 3-5 parts of zinc dialkyl dithiophosphate, 0.5-1 part of an anticoagulant, 0.5-1.5 parts of a dispersing agent, 5-10 parts of an ultraviolet light absorber, and the balance of base oil. The anticoagulant and the dispersing agent are added into the component A or thecomponent B or the component C in proportion; the component A, the component B and the component C are added into lubricating oil to be updated through online blending and filling equipment; and theaddition amount of the high-temperature-resistant precipitation antagonist is 0.1-0.2% of the lubricating oil to be updated. The quantitative premixing device, the nitrogen adding pulse blending device and the suction type replacement device are sequentially connected from front to back.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil preparation, and in particular relates to a high temperature resistant precipitation antagonist. Background technique [0002] In industrial production, the oxidation of lubricating oil base oils is mostly due to the oxidation, thermal oxidation and thermal degradation of various hydrocarbons, especially polycyclic aromatic hydrocarbons, in the air or under the action of engine combustion gases (especially under high temperature, light and metal catalysis). The process of oxidation and conversion into various oxidation products. The oil that has been used for a long time and oxidized will not only become darker in color, but also produce precipitation, which will affect the quality of the oil and lead to a significant decrease in the lubricating effect. [0003] Existing equipment guarantees the quality of lubricating oil, and all crude oil or raw liquid needs to be taken out after produc...
