High-performance environment-friendly formaldehyde diesel oil and preparation method thereof

The invention relates to the technical field of automobile fuel, in particular to high-performance environment-friendly formaldehyde diesel oil and a preparation method thereof.The high-performance environment-friendly formaldehyde diesel oil is prepared from, by mass, 55-75 parts of diesel oil, 20-35 parts of methyl alcohol, 7-15 parts of surfactant, 0.5-0.8 part of corrosion inhibitor, 20-30 parts of composite cosolvent, 0.8-1.6 parts of metal deactivator and 20-35 parts of polyoxymethylene dimethyl ether, the composite cosolvent comprises n-butyl alcohol, oleic acid and methyl tert-butyl ether. The high-performance environment-friendly formaldehyde diesel oil disclosed by the invention has a relatively high flash point and a relatively high cetane number, can be fully combusted in use, reduces pollution, and keeps a clear flowing state when being stored for a long time at a low temperature, and the cetane number is more stable in a storage process; in addition, heating and temperature control are not neede
