Abstract

The invention provides an antiwear complexing agent for engine oil. The antiwear complexing agent is characterized by being composed of base oil, an antioxidant, a detergent, a dispersant, an extreme pressure antiwear agent, a rust inhibitor, a pour point depressant, a metal deactivator, nanometer zinc and tungsten disulfide, wherein the antioxidant is dihydro benzothiophene; the detergent is phenate; the dispersant is polyisobutylene glyceryl maleate; the extreme pressure antiwear agent is lead naphthenate; the rust inhibitor is an alkyl succinic acid derivative; the pour point depressant is alkyl naphthalene; and the metal deactivator is benzotriazole. According to the invention, the manufacturing method is simple; and the prepared product has low price, high efficiency and high cost performance, gives full play to comprehensive effects of lubricating oil, has strong repair effect on aging and wearing of mechanical equipment, can improve oxidation-resistant, corrosion-resistant, cleaning and dispersing effects of the lubricating oil and improves antiwear and anti-extreme-pressure effects at the same time, reduces noise and exhaust emission, prolongs the oil changing period, saves fuel oil, and completely enhances comprehensive effects 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 engine oil anti-wear 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 Les...
