Problems solved by technology

[0004] However, the above-mentioned scheme has the following defects in use: a single component of polyalphaolefin base oil is used, and the performance is single. In addition, when the mechanical surface is in contact, the buffer effect cannot be formed in the oil film, which may easily cause the oil film to rupture and reduce the lubrication protection effect.

Abstract

The invention discloses energy-saving environment-friendly gasoline engine lubricating oil. The lubricating oil is prepared from the following ingredients weighed in parts by weight: 50-70 parts of base oil, 1-3 parts of nano silicon dioxide, 1-3 parts of a clearing agent, 2-3 parts of a dispersing agent, 3-5 parts of an extreme pressure antiwear agent, 2-4 parts of a friction modifying agent, 4-8parts of a viscosity index improver, 0.2-0.5 part of a metal deactivator, 0.3-0.5 part of an antioxidant and 0.2-0.6 part of an antifoaming agent. By mixing synthetic base oil with vegetable oil, thebase oil simultaneously has the characteristics of the synthetic oil and the vegetable oil, the processing cost of spent lubrication oil is lowered, the synergistic lubricating effect is better, hydrogen gas is introduced to carry out hydrotreatment, modification treatment can be further carried out on the base oil, the quality of the base oil is improved, by adding the nano silicon dioxide, buffer particles can form in an oil film structure, the oil film is kept stable, the abrasion between mechanical structures is lowered, and the friction between mechanical surfaces is reduced, thereby being conducive to the energy-saving environment-friendly development requirement on an engine.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to an energy-saving and environment-friendly gasoline engine lubricating oil. Background technique [0002] Lubricating oil base oils are mainly divided into three categories: mineral base oils, synthetic base oils and vegetable oil base oils. Mineral base oils are widely used and used in a large amount (about 90%), but in some applications, synthetic base oils and vegetable oil base oils must be used, and ester oils are used as high-end lubricating oils. [0003] For example, the patent application number CN201610185462.4 discloses an energy-saving and environment-friendly gasoline engine lubricating oil, including base oil and additives. agent, compound dispersant, compound anti-oxidant and anti-corrosion agent, metal deactivator, anti-rust agent and anti-foaming agent, the mass percentage of each component used is: base oil 75%-87%; viscosity index improver 3...
