Abstract

The invention belongs to the field of industrial lubricant, concretely relates to a dry type lubricant without containing grease and its mother liquor. According to the invention, the mother liquor of the dry type lubricant without containing grease is prepared by 0.01 to 95 parts of nanoparticle and 5 to 99.99 parts of volatile solvent which is in a liquid state under the normal temperature. Theinvention also discloses a nanometer lubricating agent without containing grease, which consists of a nanoparticle deposition layer attached on a frictional pairs surface or a residual volatile hydrocarbon deposition layer existed in liquid state under the normal temperature. Nanoparticles are dispersed for dissolving in volatile hydrocarbon, nanoparticles can be stablely attached to the frictional secondary surface due to large surface energy when using, only nanoparticles with lubrication efficacy are left after volatilizing hydrocarbon, a dry type oil free film can be formed, thereby the lubricant has the effect of pollution resistance and high temperature resistance, and has good lubricity.

Description

technical field [0001] The invention belongs to the field of industrial lubricants, in particular to a grease-free dry lubricant and its mother liquor. Background technique [0002] Friction and wear is an inevitable phenomenon in the friction process. Friction loses about one-third of the world's energy, and wear is one of the main forms of damage and failure of materials and equipment. The role of the lubricant is to prevent the contact of asperities when the contact parts move with each other. At a higher sliding speed, it forms a liquid film by adsorbing the lubricating liquid molecules on the metal surface, and thus blocks the roughness of the friction surface. s contact. [0003] At present, lubricants are mainly divided into oil-based lubricants and water-based lubricants. Oil-based lubricants mainly use grease as a carrier, and various additives are added to meet various lubrication requirements. When used, the grease will adhere to the friction pair to form an "oi...
