Embodiment 1

[0024] see figure 1 , the present invention provides a technical solution: an anti-oxidation system extreme pressure anti-wear self-repairing lubricating oil additive, the anti-oxidation system extreme pressure anti-wear self-repairing lubricating oil additive includes antioxidants, extreme pressure anti-wear agents, polyisobutylene Diimide and organic molybdenum, lubricating oil will shorten the life due to oxidation, antioxidant can significantly improve the oxidation stability of the oil, the two metal surfaces that move relative to each other under normal load are completely separated by the lubricating oil film, There is no direct contact with the metal. As the load increases, the thickness of the oil film between the metal surfaces gradually decreases. When the load increases to a certain level, the continuous oil film is destroyed by the peaks of the metal surface, and direct contact between the metal surfaces occurs locally. , direct contact with the metal surface gene...

Abstract

The invention belongs to the technical field of lubricating oil additives, and particularly relates to an antioxidant system extreme pressure anti-wear self-repairing lubricating oil additive and a preparation method thereof. The antioxidant system extreme pressure anti-wear self-repairing lubricating oil additive comprises an antioxidant, an extreme pressure anti-wear agent, polyisobutylene succinimide and organic molybdenum, the preparation method of the antioxidant system extreme-pressure anti-wear self-repairing lubricating oil additive comprises the following steps: filtering and mixing powder, mixing liquid, filtering the liquid, putting the antioxidant, the extreme-pressure anti-wear agent, the polyisobutylene succinimide and the organic molybdenum into a stirrer, heating and stirring. The antioxidant, the extreme-pressure anti-wear agent, the polyisobutylene succinimide and the organic molybdenum can beed conveniently, large-particle powder can be prevented from entering mixedliquid by filtering the mixed powder, and large particles caused by particle bonding during mixing and stirring can be filtered by filtering the mixed liquid; therefore, large-particle substances areprevented from appearing in the lubricating oil additive.

Description

technical field [0001] The invention relates to the technical field of lubricating oil additives, in particular to an anti-oxidation system extreme pressure anti-wear self-repairing lubricating oil additive and a preparation method thereof. Background technique [0002] Lubricating oil additives refer to one or several compounds added to the lubricating oil, which can make the lubricating oil acquire some new characteristics or improve some existing characteristics of the lubricating oil. According to the function, the additives mainly include antioxidants, antiwear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and anti-rust agents, flow point improvers, and viscosity index enhancers. types of agents. The additives sold in the market are generally compound products of the above single additives. The only difference is the composition of the single additive and the ratio of several...
