Problems solved by technology

Polyhexafluoroethylene micro-powder anti-wear agent has high temperature resistance and anti-wear and anti-friction properties, but polyhexafluoroethylene has poor oil solubility and is easily precipitated from the oil, depositing at the bottom of the oil, affecting the anti-wear and anti-friction effect; patent CN 103756761 A Adding nano-boron additives is the most extreme pressure agent and friction reducer. Although the boron additives do not contain sulfur and phosphorus and have little environmental pollution, the oil solubility of boron substances is not good, and the stability in oil is not good. It is easy to precipitate when placed for a long time, which affects the use effect, and boron substances are easy to hydrolyze. If water is mixed in the oil during use, boron substances are easily hydrolyzed and lose the anti-wear effect

Abstract

The invention discloses gasoline engine oil with long service life and multiple anti-wear protection means and a preparation method of the gasoline engine oil. The gasoline engine oil with long service life and multiple anti-wear protection means comprises raw materials in percentage by mass as follows: 7%-15% of a gasoline and engine oil complexing agent, 3%-13% of a viscosity index improver, 0.3%-0.5% of an antioxidant, 0.2%-0.5% of a corrosion inhibitor, 0.2%-0.5% of a pour point depressant, 0.5%-1% of an anti-wear agent, 0.002%-0.005% of an anti-foaming agent and the balance of base oil. The gasoline engine oil is at a lower temperature at an initial use stage and forms an adsorption film on the surface of a friction pair to protect an engine; with running of a vehicle, the oil temperature is increased, an ester film falls off from the surface of the friction pair, a chemical film formed by molybdenum dialkyl-dithiocarbamate protects the friction pair at the moment, and friction is reduced; when the oil temperature is increased continuously, anti-wear protection of the protective film formed by molybdenum dialkyl-dithiocarbamate is weakened, and then a protective film formed by a molybdenum and amine complex continuously plays a role to protect the oil.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, and relates to a long-life gasoline engine oil with multiple anti-wear protections and a preparation method thereof. Background technique [0002] With the improvement of environmental regulations and the improvement of people's awareness of environmental protection, engine technology has also developed, mainly towards high speed, high compression ratio, light weight, and small wind resistance. Engines These technological developments have led to increases in engine operating temperatures. Increased engine temperature has negative effects on the engine, such as accelerated oil oxidation, accelerated engine wear, deposits such as carbon deposits, reduced power, increased fuel consumption, and increased pollutant emissions. [0003] In order to comply with the development of engine technology, the technology of gasoline engine oil also develops accordingly. Modern gasoline engine oil requi...
