Nanoparticles are often added to gasoline engine oil as a friction modifier. Nanoparticles will fill and repair the worn metal surface on the surface of the friction pair, and form a lubricating film, which can effectively reduce the wear loss of the engine. In addition, due to the accumulation of gas in the pores of the nanoparticles, when the nanoparticles and gasoline engine oil are mixed, the gas accumulated in the pores overflows, forming a large number of fine bubbles, which affects the quality of gasoline engine oil

Abstract
The invention relates to semisynthetic gasoline engine oil and a preparation method thereof, and belongs to the technical field of lubricating oil. The semisynthetic gasoline engine oil comprises thefollowing raw materials: mineral base oil HVI150, mineral base oil HVI500, poly alpha-olefin synthetic base oil, a viscosity index improver, a composite function additive, a pour pointreducer and a defoaming agent, wherein the composite function additive comprises molybdenum dialkyldithiocarbamate, nanometer molybdenum disulfide, dibenzyldithiocarbamic acid sodium salt, polyisobutylene succinimide, calciumphytic acid, trimethyl hydroxypentyl isobutyrate and butylated hydroxyethyl benzene; the semisynthetic gasoline engine oil is prepared and obtained according to the method comprising the steps of mixing, stirring, program warming, and program cooling in sequence. According to the semisynthetic gasoline engine oil, the dispersibility of nanometer molybdenum dioxide is improved, bubbles inside the nanometer molybdenum dioxide are reduced, and the semisynthetic gasoline engine oil has good functions of lubrication, abrasion resistance, oxidation resistance, defoaming, energy conservation and emission reduction.
Description
technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a semi-synthetic gasoline engine oil and a preparation method thereof. Background technique [0002] In the current development of the automobile industry, there are many metal surfaces in the engine that rub against each other. Especially for new cars leaving the factory or after engine overhaul of old cars, the fit gaps of various parts are uneven or too tight, and running-in adjustment is required. As a kind of lubricating oil, gasoline engine oil plays an increasingly important role in reducing friction in the engine. Nanoparticles are often added to gasoline engine oil as a friction modifier. Nanoparticles will fill and repair the worn metal surface on the surface of the friction pair, and form a lubricating film, which can effectively reduce the wear loss of the engine. In addition, due to the accumulation of gas in the pores of the nanoparticles, when the nanopar...
