Problems solved by technology
However, because most of the titanium dioxide powders currently added are micron-sized, the effect is only on the removal of carbon residues, it is difficult to effectively fill the gaps, and the adsorption force to the cylinder wall is poor, so the durability is poor
In addition, the continuous presence of organic solvents in engine oil may damage the characteristics of the base oil or increase the possibility of damaging other additives, thereby changing the dynamic viscosity of the oil and causing damage to the cylinder

experiment example 1
[0026] Titanium dioxide with a particle size of 10nm-100nm is dispersed in an alcohol solution to form an aqueous sol, wherein the content of titanium dioxide is 0.1%-5% (w / w) based on the total weight of the aqueous sol. The engine oil and the water-based sol were mixed at a ratio of 80g:5mg, and after mixing evenly, the alcohol was drained by vacuum pumping to prepare an engine oil composition.

Abstract
The invention provides an engine oil composition and a preparation method thereof. The steps of the preparation method include preparing an aqueous sol containing metal oxides, mixing the engine oil and the aqueous sol, and removing the polar liquid medium of the aqueous sol to obtain an engine oil composition thing. The preparation method can reduce the damage of the engine oil composition containing the metal oxide as the anti-wear additive due to contact with the oil-soluble solvent.
Description
technical field [0001] The present invention relates to a kind of engine oil composition, especially relates to a kind of engine oil composition which is formed by formulating metal oxide into water-based sol to be mixed into engine oil. Background technique [0002] Adding engine oil to the gasoline cylinder keeps the various components of the engine lubricated, prevents corrosion and rust, and keeps the vehicle engine running smoothly. Most of the known engine oils contain base oil and additives. The function of the base oil is to maintain the lubrication between the components, while the additives are used to make up for the lack of existing characteristics of the base oil components, or to further provide auxiliary functions. , such as auxiliary additives such as detergents, dispersants, antioxidants, anti-rust or anti-corrosion additives, viscosity or flow improvers or anti-wear additives. [0003] The above-mentioned additives are mostly prepared by dissolving the mai...
