MOFs nanoparticle composite gel lubricant and preparation method thereof

The invention discloses an MOFs (Metal-Organic Frameworks) nano-particle composite gel lubricant and a preparation method thereof. The MOFs nano-particle composite gel lubricant comprises modified MOFs nano-particles, a gelator and base oil, the modified MOFs nano particles are selected from one or more of UiO-66-NH2-O nano particles modified by oleic acid diethanolamide, ZIF-8-O nano particles modified by oleic acid diethanolamide and HKUST-1-O nano particles modified by oleic acid diethanolamide; the gelator is 12-hydroxy stearic acid; the base oil is poly-alpha-olefin. According to the invention, gel factors are introduced to form supramolecular oil gel, and the supramolecular oil gel and the MOFs material form a nano-particle composite gel lubrication system, so that the problems of stable dispersion and creeping of the MOFs nano material are solved, a new way is provided for application of MOFs nano-particles in lubricants, and the application prospect is good. 本发明公开了一种MOFs纳米颗粒复合凝胶润滑剂及其制备方法，MOFs纳米颗粒复合凝胶润
