Abstract

The invention discloses a diethoxymethane diesel engine oil composition. The diethoxymethane diesel engine oil composition is prepared by adopting class II base oil and pentaerythritol ester as base oil and cooperating with various composite additives. The diethoxymethane diesel engine oil composition comprises an anti-wear agent, an antioxidant preservative, an anti-foaming agent, a viscosity index improvement agent, a metal deactivating agent, a cleaning agent, a dispersing agent, an antioxidant and an oiliness agent. The diesel engine oil composition disclosed by the invention has excellent cleaning and dispersing effects, can be used for preventing a piston ring from sticking, has excellent viscosity-temperature characteristics, excellent alkali value retainability and acid neutralization capacity, can be used for inhibiting the generation of black oil sludge, ensures that an engine is cleaner, has good anti-high-temperature oxidation stability, high shear stability, rubber compatibility, good low-temperature startability and excellent fuel oil economical efficiency, can not cause corrosion to moving components, ensures that an oil product can maintain enough oil film strength, and can be used for reducing the wear.

Description

technical field [0001] The invention belongs to the field of internal combustion engine lubricants, in particular to a formaldehyde grease diesel engine oil composition. Background technique [0002] The subname of formaldehyde fat is diethoxymethane, commonly known as formaldehyde fat, molecular formula C 5 h 12 o 2 , molecular weight 104, density 0.8319kg / L, octane number (MON): 65, is a colorless liquid. Formaldehyde resin is usually derived from by-products of industries such as chemical and pharmaceutical industries, and has long been discharged as waste. This is not only a waste of energy, but also causes environmental pollution. At the same time, it is also a strong solvent, which can be miscible with various internal combustion engine fuels such as gasoline, diesel oil, heavy diesel oil, methanol, cottonseed oil, soybean oil, rapeseed oil, waste animals, and vegetable oils. This feature is its advantage for using it as an internal combustion engine substitute fu...
