Described a kind of antiseptical, high abrasion-resistant environmental protection energy-saving engine lubricating oil and preparation method thereof, it is characterised in that by Following steps are made：
A. sulphur powder and tungsten powder are mixed, forms mixture, the mixture is reacted at a temperature of 110-260 DEG C, then Reactant is crystallized at a temperature of 500-700 DEG C in nonoxidizing atmosphere, that is, is obtained tungsten disulphide powder and remaining Sulphur powder mixture；
B. step a gained mixture is mixed with deionized water, adds linoleic acid, the fat of phosphorous acid fourth three, obtain suspension, Feeding after suspension 8-12h is processed using ball grinding stirring in strong ultrasonic field, lyophilization obtains ultra-fine tungsten disulfide and mixes with sulfur Thing powder；
C. by step b gained mix powder be scattered in dimethyl sulfoxide solvent, and be added thereto to zeolite ZIF-8, poly- third Olefin(e) acid sodium, proceeds in ptfe autoclave after stirring, and after placing 5-10 days under the conditions of 80-120 DEG C, filters and is used in combination Absolute ethanol washing 2-4 time, after drying at room temperature, obtains adsorbing ultra-fine tungsten disulfide and sulfur powder, and has dimethyl sulfoxide to fill Zeolite ZIF-8 mixture；
D. by Oleum Brassicae campestriss, polyalphaolefin PAO6, polyol ester PriEco3004 mixing, pour-point depressant LZL803B, mahogany acid are added Barium, ethylene-propylene copolymer T618, step c gained mixture, proceed to stirring 30-90min in blender.
Described a kind of antiseptical, high abrasion-resistant environmental protection energy-saving engine lubricating oil and preparation method thereof, it is characterised in that stir The rotating speed for mixing machine is 200-400r/min.
The invention has the beneficial effects as follows：The present invention hangs tungsten disulfide using strong ultrasound and the compound action of ball grinding stirring The close nano tungsten disulfide grain graininess of floating particles granularity, then moditied processing is carried out to particle surface by linoleic acid, it is effectively anti- Stopped it is intergranular reunite again so that tungsten disulfide granule keeps stable dispersion in base oil, improve its stability； Hydrophobic lipophilic material zeolite ZIF-8 is introduced, and is soaked with dimethyl sulfoxide, not only can be using zeolite ZIF-8 as tungsten disulfide The carrier of granule, further improves its amalgamation with base oil, at the same zeolite ZIF-8 can as excellent lubricating additive, With tungsten disulfide together to strengthen the bearing capacity and antiwear and antifriction ability of lubricating oil, and dimethyl sulfoxide then promotes zeolite The fusion faculty of ZIF-8 carriers and lubricating oil.It is used as subjective basis oil by Oleum Brassicae campestriss, improves the feature of environmental protection of the lubricating oil Can, environmental friendliness；Cooperation with the addition of petroleum sodium sulfonate etc., improve the antiseptic property of lubricating oil.
