Problems solved by technology

However, the current popular antioxidants for lubricating oils mainly use chemical substances such as metal salts, hindered phenols, and aromatic amines as the main antioxidant components of lubricating oils. Unstable, increased mechanical wear, or because it contains harmful substances to the human body, once it is lost to the environment, it will inevitably cause great harm to the surrounding ecological environment

Abstract

The invention discloses an airgel-loaded vegetable-based lubricating oil additive, comprising: in parts by mass, the additive comprises modified airgel nanoparticles, vulcanized or hydroxylated vegetable oil and an alkaline earth metal detergent, wherein , the vegetable oil comprises seabuckthorn seed oil and sunflower oil. The preparation method of the additive comprises: mixing vulcanized or hydroxylated vegetable oil and calcium salicylate according to a preset ratio, stirring thoroughly to obtain a mixture; mixing the mixture with modified airgel nanoparticles, and stirring sufficiently to obtain a finished product . The lubricating oil additive of the invention has the advantages of reducing the friction resistance between friction parts, reducing the damage probability of the friction parts, enhancing the oxidation resistance and wear resistance of the lubricating oil and prolonging the service life of the lubricating oil.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil additives, and in particular relates to an airgel-loaded vegetable-based lubricating oil additive and its preparation method and application. Background technique [0002] Lubricating oil is a type of liquid or semi-solid lubricant widely used in automobile engines and mechanical equipment to reduce friction between two moving parts and reduce wear between two parts in contact with each other. Lubricating oil generally consists of two parts: base oil and additives. Among them, the base oil constitutes the main component of the lubricating oil, which determines the basic properties of the lubricating oil; while the additive is an indispensable component of the lubricating oil, which makes up for some defects in the performance of the base oil and endows the lubricating oil with new properties. performance. [0003] Antioxidants are an important class of additives in lubricating oils, and ...
