The invention discloses a methanol gasoline and a preparation method thereof, relating to the field of new energy. The methanol gasoline comprises 15-30wt% of methanol, 67-83wt% of gasoline and 2-3wt% of additive. The preparation method comprises the following steps: pouring solubilizer, energy increasing and consumption reducing agent, anti-oxidant, metal corrosion inhibitor, rubber swelling inhibitor into a reaction vessel according to a required proportion with stirring, mixing uniformly to obtain an additive; mixing the additive with methanol according to a required proportion to obtain modified methanol; and mixing the modified methanol with gasoline according to a required proportion to obtain the methanol gasoline. The methanol gasoline disclosed in the invention has the advantagesof simple preparation and good performance, can be used mixed with a national standard gasoline in any proportion with similar energy consumption with the national standard gasoline and emission indexes that conforms to requirements of environmental protection, and can be widely used for various petrol-engined motor vehicles, such as car, carriage, fork truck, power-assisted vehicle, farm vehicle, motorcycle, load wagon and forklift.

The invention discloses a preparation method and application of an oleic acid-modified copper sulphide nano-material.Copper acetate, thioacetamide and oleic acid serve as raw materials, and a water bath method or hydrothermal method is adopted to prepare the oleic acid-modified copper sulphide nano-material.The preparation method includes the steps that firstly, a thioacetamide and oleic acid mixed solution and a copper acetate solution are prepared; then, the copper acetate solution is dropwise added into the thioacetamide and oleic acid mixed solution, and a reaction is performed with the water bath method or hydrothermal method to obtain copper sulphide nano-rods.Compared with a CuS nano-material not modified with oleic acid, the oleic acid-modified copper CuS nano-material has the advantages that the wear rate is reduced to 3.05*10<-17>m<3>.N<-1>.m<-1> from 2.37*10<-16>m<3>.N<-1>.m<-1>, the friction coefficient is reduced to 0.0345 from 0.0618, the friction and wear performance of lubricating oil is greatly improved, the friction coefficient and the wear rate are effectively reduced, and the oleic acid-modified copper CuS nano-material can serve as a nano-lubricating oil additive.Besides, the preparation technology is simple, and the cost is low.
