DETAILED DESCRIPTION - A high wear-resistant environmentally-friendly energy-saving graphene-containing engine oil comprises 1-3 pts. wt. graphene, 50-70 pts. wt. rapeseed oil, 2-4 pts. wt. petroleum ether, 15-25 pts. wt. poly-( alpha )-olefin-6, 6-15 pts. wt. PriEco 3000 (RTM: Polyol ester), 1-2 pts. wt. boron nitride, 4-8 pts. wt. sulfur powder, 0.5-1 pt. wt. tungsten powder, 5-10 pts. wt. ZIF-8 zeolite, 2-3 pts. wt. linoleic acid, 15-20 pts. wt. dimethyl sulfoxide, 5-10 pts. wt. pour point depressant LZL803B, 4-7 pts. wt. ethylene-propylene copolymer T618, 15-20 pts. wt. deionized water, and certain amount of anhydrous ethanol. An INDEPENDENT CLAIM is included for preparation of high wear-resistant environmentally-friendly energy-saving graphene-containing engine oil, which involves (i) mixing sulfur powder and tungsten powder to form a mixture, reacting the mixture at 110-260 degrees C, crystallizing in a non-oxidizing atmosphere at 500-700 degrees C to obtain tungsten disulfide powder-and-sulfur powder mixture (a), (ii) mixing mixture (a), graphene, and boron nitride with deionized water, adding linoleic acid to obtain a suspension, ultrasonically treating the suspension in a ball mill for 8-12 hours, and freeze-drying to obtain ultra-fine mixed powder (b), (iii) dispersing the mixed powder (b) in a dimethyl sulfoxide solvent, adding ZIF-8 zeolite, uniformly stirring and adding into a polytetrafluoroethylene reactor, placing at 80-120 degrees C for 5-10 days, filtering and washing with anhydrous ethanol for 2-4 times, drying at room temperature to obtain mixture (c), (iv) adding rapeseed oil, petroleum ether, poly-( alpha )-olefin-6, PriEco 3000 (RTM: Polyol ester), pour point depressant LZL803B, ethylene-propylene copolymer T618, and mixture (c) into a mixer, and stirring for 30-90 minutes.
