Abstract

The invention provides graphene lubricating grease. The compound is prepared from the following components in parts by weight: 70-80% of lubricating grease, 13-17% of a thickening agent, 1-3% of an additive and the balance of graphene base oil. The invention further provides a preparation method of the compound and application of the compound to preparation of lubricating oil with energy saving and emission reduction effects. The compound provided by the invention has the advantages that the lubricating performance of the lubricating oil can be significantly improved, the friction coefficientis decreased, the abrasion loss is greatly reduced, and the significant friction corrosion resistant performance is achieved; meanwhile, by dispersing a surface-modified graphene nano material into the base oil for the lubricating oil, a layer of abrasion resistant graphene film can be formed on a friction interface; therefore, the graphene lubricating grease has great lubricating performance, abrasion resistance, corrosion resistance, oxidation resistance and rust resistance, and can significantly prolong the life of mechanical parts.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a graphene lubricating grease and a preparation method and application thereof. Background technique [0002] According to the statistics of international authoritative organizations, the three major losses of metal material wear, corrosion and fatigue account for about 30% of the total industrial output value, and friction and wear are ubiquitous natural phenomena. Friction loses about one-third of the world's primary energy. Wear is one of the three main forms of damage and failure of materials and equipment. Lubrication is the most effective technology to reduce friction and reduce or avoid wear. It is one of the important topics of contemporary chemistry, material science and tribology to develop lubrication technology with good anti-wear performance, high load-carrying capacity, certain repair function on worn surface, and no or less pollution to the environment. ...
