Abstract
The invention relates to an SG gasoline-engine oil composition, and a preparation method and application thereof, belonging to the technical field of materials. The SG gasoline-engine oil composition is prepared from the following components in parts by mass: 70-80 parts of SG gasoline-engine oil, 10-15 parts of meerschaum, 1-3 parts of nickel oxide and 1-2 parts of lithium 12-hydroxystearate. The SG gasoline-engine oil composition solves the problem that black oil sludge can be easily generated in the engine cylinder under the repeatedly alternate traveling conditions of high-temperature high speed and low-temperature low speed, and can quickly form a superhard anti-wear layer in the engine cylinder and on the piston ring, thereby keeping the effective power of the engine and reducing the emission of PM2.5 particulate matters in tail gas. The invention can also save the consumption of the lubricant, thereby achieving the effect of environmental protection. The invention has the advantages of accessible product raw materials, scientific formula, simple production technique, low cost and favorable properties, and is especially suitable for lubricating advanced gasoline engine automobiles at present.
Description

Summary of the invention
The purpose of this invention is to provide a kind of New type of S G gasoline engine oil extreme pressure antiwear composite; This compsn can form the superhard wear layer fast in engine cylinder-body with on the piston-ring; Remove black greasy filth simultaneously, in cylinder body, under the hot environment, black greasy filth is fully burnt; The active power that keeps mover reduces the discharging of tail gas PM2.5 PM for particulate matter.
The technical scheme that the present invention deals with problems is: a kind of SG composition oil of gasoline engine, and said composition is made up of following component by mass parts:
The particle diameter of the preferred sepiolite of above-mentioned SG composition oil of gasoline engine≤1 μ m.
The mass parts of the preferred nickel oxide of above-mentioned SG composition oil of gasoline engine is 2.
The mass parts of the preferred lithium 12-hydroxy stearate of above-mentioned SG composition oil of gasoline engine machine is 1.6.
Another object of the present invention provides the method for preparing the SG composition oil of gasoline engine, and this preparation method comprises the steps:
1. sepiolite powder is broken to granularity≤1 μ m, at 380 ℃ of dry 1h;
2. take by weighing the 1. sepiolite 10～15 of gained of step by mass parts, SG gasoline engine oil 70～80, nickel oxide 1～3, lithium 12-hydroxy stearate 1～2 is mixed to join in the closed unit, and vacuum tightness is reached-0.08MPa;
3. be warming up to 85 ℃, 10000rmp stirs 10min down, and rotating speed is adjusted into 18000rmp and stirs 6min down, and rotating speed is adjusted into 28000rmp and stirs 4min down;
4. fine dispersion 10min in the 1KW ultra-sonic generator.
Another purpose of the present invention provides the application of SG composition oil of gasoline engine in petrol motor vehicle petrol engine.
The beneficial effect that the present invention produces: SG composition oil of gasoline engine of the present invention can make in the engine cylinder-body with on the piston-ring and form the superhard wear layer fast, generates complete strengthening surface in the 60s.Remove black greasy filth simultaneously; Having solved high temperature and high speed and low temperature low speed intersects under the travel situations repeatedly; In engine cylinder-body, produce black greasy filth problem easily, in cylinder body, under the hot environment, black greasy filth is fully burnt; The active power that keeps mover reduces the discharging of tail gas PM2.5 PM for particulate matter.
