摘要： A super-lubricity water lubricating additive, a super-lubricity water lubricant, a preparation method and application, wherein the additive is of a hollow spherical shell structure which includes at least one layer of spherical shell; the spherical shell sequentially includes a first polydopamine layer, a nanoparticle layer, a second polydopamine layer and an oxidized graphene layer from inside to outside, or a first polydopamine layer, a nanoparticle layer, a second polydopamine layer, a graphene layer and a third polydopamine layer from inside to outside; and nanoparticles of the nanoparticle layer are nano diamond, nano molybdenum disulfide or nano tungsten disulfide. The additive is prepared into a uniform aqueous solution to obtain the super-lubricity water lubricant. The additive can be easily adsorbed on a dual surface, and the nanoparticles released in a friction process cooperate with spherical oxidized graphene or graphene to form rolling friction so as to reduce frictional abrasion.
