Abstract
The invention discloses lubricating grease for a bearing. The lubricating grease comprises the components in parts by mass: 75-85 parts of base oil, 5-15 parts of a thickening agent, 1-10 parts of zeolitic imidazolate and 1-6 parts of other additives, wherein the base oil is a mixture obtained by mixing poly-alpha-olefin and alkyl naphthalene according to different ratios, and the thickening agent is an inorganic thickening agent or an organic thickening agent. The lubricating grease for the bearing, disclosed by the invention, is prepared by taking zeolitic imidazolate (ZIFs), namely a nonmaterial with a porous skeleton structure, as an additive, so that the prepared lubricating grease has favorable mechanical property, scalability and stability, and the wear resistance and compression resistance of the lubricating grease can also be improved.
Description
Technical field
The invention belongs to technical field of petrochemical industry, relate to a kind of bearing lubricating grease adding zeolite imidazole ester (frame structure material).
Background technology
Rolling bearing, as typical " antifriction " mechanical basic part, lost efficacy because resistance makes bearing constantly wear and tear at the volley, the difference of lubricant and lubricating system, different to reduction bearing friction abrasive effect.Lubrication technology is the important component part of bearing technology research always.Lubricating grease is thought the 5th part of the bearing of running neck and neck with inner ring, outer ring, rolling body, maintenance by domestic and international design bearing and producer.
Advanced lubrication technology is the core technology of energy-saving strategy, modern society, and lubricant applications field is extensive, and the equipment of nearly all motion all needs lubrication.Internal authority mechanism calculates, and the 30%-50% of world energy sources is consumed in frictional wear, and the mechanical material loss of more than 60% is in wearing and tearing, and the mechanized equipment serious accident of more than 50% all results from the overwear vt. that lubrication failure causes.
Zeolite imidazole ester (ZIFs) is with a metal-organic complex formed containing organic ligand imidazoles or derivatives thereof, it is the novel nanoporous function framework material of a class, because it has good mechanical property, scalable performance, hardness performance and hydrophobic lipophilicity, and be widely used; In lubricating grease, effectively can improve again anti-friction and the compressive property of lubricating grease as additive.
Summary of the invention
The object of this invention is to provide a kind of bearing lubricating grease, adopt the nano material-zeolite imidazole ester (ZIFs) with porous skeleton structure as additive, make the lubricating grease of preparation not only have good mechanical property, scalable performance and stability, and the wear-resistant of lubricating grease and compressive property can also be improved.
The invention provides a kind of bearing lubricating grease, comprising:
The base oil of 75 ~ 85 mass parts;
The thickening material of 5 ~ 15 mass parts;
The zeolite imidazole ester of 1 ~ 10 mass parts;
Other additives of 1 ~ 6 mass parts.
Preferably, described base oil is the mixture of polyalphaolefin and alkylnaphthalene different ratios, and wherein, the mass ratio of polyalphaolefin and alkylnaphthalene is 75:25 ~ 25:75.
Preferably, described thickening material is inorganic thickening agent or organic thickening agent, inorganic thickening agent can be a kind of in natural clay, wilkinite, Attapulgite, silica gel, nano silicon, carbon black or their mixture, and organic thickening agent can be a kind of in polyurea based, tetrafluoroethylene, indanthrene or their mixture.
Preferably, the particle diameter of described additive zeolite imidazole ester is 50 ~ 500 nm.
