Description

A kind of normal propyl alcohol gasoline engine engine oil base oil
Technical field
A kind of normal propyl alcohol gasoline engine engine oil base oil of the present invention belongs to petrol engine lubricating oil field.
Background technology
Normal propyl alcohol, also known as 1- propyl alcohol, propyl alcohol, molecular formula (C3H7OH), molecular weight is 60.10, is water white liquid, Water, ethanol, ether is dissolved in, is had as ethanol smell.Ethene obtains propionic aldehyde through carbonylation synthesis, then obtains through reduction.It is mainly used to do and fires The bactericide of material oil, agricultural chemicals and medical material, perfume base.As solvent and for pharmacy, paint and cosmetics.Its fusing point- 127 DEG C, relative density 0.80,97.1 DEG C of boiling point, 15 DEG C of flash-point, the cosolvent of ethanol is also used for, also can be called in as fuel In gasoline, ratio 0～20%.
Increasingly serious with energy crisis and environmental problem, the fuel combination of alcohols and traditional fossil fuel or completely Alcohols replaces fuel to be increasingly subject to pay attention to.Wherein normal propyl alcohol is applied because of the breakthrough of dixie cup method and on the engine.Mixed Close in fuel, alcohols is affected to be showed its distinctive flammability by active group, contributes to improving to fuel combination further Fired state, it helps reduce discharge.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of with low ash content, prevents spark from blocking, good high temperature Lubricity, detergent-dispersant performance, dissolubility, base number retentivity, anti-corrosive properties, antirust, emulsion resistance, anti-shearing, wear resistence and anti-alcohols The normal propyl alcohol gasoline engine engine oil base oil of contaminative.
The present invention employs the following technical solutions solution above-mentioned technical problem：
A kind of normal propyl alcohol gasoline engine engine oil base oil, oil based on being combined using HVIH base oil and poly alpha olefin, Coordinate multiple compound additives, its each mass percent become to be grouped into：
