Abstract

The invention discloses anti-oxidation lubricating oil. The anti-oxidation lubricating oil comprises the following components in parts by weight: 80-90 parts of base oil, 2-6 parts of 4-butyldiphenylamine, 0.2-1 part of surface modified nano silicon carbide particles and 2-6 parts of molybdenum-containing compound, and further discloses a preparation method of the anti-oxidation lubricating oil. The anti-oxidation lubricating oil is included. The preparation method of the antioxidant lubricating oil comprises the following steps: preparing 4-butyldiphenylamine; preparing surface modified nanosilicon carbide particles; enabling the 4-butyldiphenylamine, surface-modified nano silicon carbide particles, the molybdenum-containing compound and base oil to be matched in parts by weight to prepare a composition, wherein the composition reacts under preset conditions to prepare the antioxidant lubricating oil; and on the basis of the prior art, the surface-modified nano silicon carbide particles and the 4-butyldiphenylamine are additionally arranged in the base oil, so that the antioxidant stability of the lubricating oil is improved effectively; and the molybdenum-containing compound isadditionally arranged and is matched with the surface-modified nano silicon carbide particles, so that the antioxidant stability of the lubricating oil is improved.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to an anti-oxidation lubricating oil and a preparation method thereof. Background technique [0002] Friction and wear widely exist in daily life and in nature, thus causing problems such as energy consumption and mechanical loss to become increasingly prominent. The use of lubricating oil is considered to be an important method to effectively reduce or even eliminate the problem of friction and wear. The use of lubricating oil can effectively reduce friction and wear. However, due to the heat generated by mechanical friction, lubricating oil is easily oxidized, resulting in reduced lubricating performance of lubricating oil. Contents of the invention [0003] In order to solve the problem in the prior art that lubricating oil is easily oxidized due to mechanical friction and heating, an anti-oxidation lubricating oil and a preparation method thereof are propos...
