Abstract

The invention relates to an anti-wear lubricating oil composite agent, which is characterized by comprising base oil, an antioxidant, a cleaning agent, a dispersant, an extreme pressure anti-wear agent, a rust corrosion inhibitor, a pour point depressant, a metal deactivator, nanometer zinc, and tungsten disulfide, wherein the antioxidant is glycerol monooleate, the cleaning agent is a sulfated polyisobutylene salt, the dispersant is a styrene ester derivative, the extreme pressure anti-wear agent is vulcanized isobutylene, the rust corrosion inhibitor is synthetic sodium sulfonate, the pour point depressant is alkyl naphthalene, and the metal deactivator is benzotriazole. According to the present invention, the manufacturing method is simple; and the prepared product has characteristics of low price, high efficiency, high performance price ratio, complete providing of the comprehensive effect of the lubricating oil, strong repair on the aging wear of the mechanical equipment, improvement of the oxidation resistance and the corrosion resistance of the lubricating oil, cleaning effect, dispersing effect, simultaneous improvement of the wear resistance and the extreme pressure resistance, noise reducing, tail gas emission reducing, oil change period prolonging, fuel oil saving, and complete improvement of the comprehensive effect of the lubricating oil.

Description

[0001] (1) Technical field [0002] The invention relates to a lubricating oil additive, in particular to a preparation scheme and a manufacturing method of an anti-wear lubricating oil compounding agent. [0003] (2) Background technology [0004] At present, with the continuous innovation of industrial technology, all kinds of mechanical equipment have higher and higher requirements for the quality of lubricating oil, and the lubricating oil industry is also constantly innovating. Engine lubricating oil has accounted for more than 55% of the sum of all kinds of lubricating oil. Lubricating oil companies and R&D teams are investing more and more in automotive lubricants. The selection of base oil is very important for lubricating oil production, and the selection of additives is even more important, because lubricating oil plays a very important role in the normal operation and maintenance of mechanical equipment, and good additives on the market, especially compounding agents...
