Abstract

The invention is a kind of nano antiwear additive and the manufacturing method and the application. The nano antiwear additive is made up of polyisobutylene and carbon nano pipe, the proportion of each ingredients are: 50-99, 1-50. the producing steps include: mixing the polyisobutylene, carbon nano pipe according to a proportion; stirring them or putting them into the globe mill; putting them into the triple-roller mill, or using supersonic wave machine to carry on decncentration for 25-35 minutes. It uses 3% nano antiwear additive and 97% lubricating oil to produce nano lubricating oil, uses 80% nano antiwear additive and 20% lubricating oil as automatic renovation agent, the producing method is: nano antiwear additive, lubricating oil are mixed together, and gets the product through heating, and cooling.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a nanometer anti-wear agent and its preparation method and application. Background technique [0002] At present, research on the application of nanomaterials in various related fields has been carried out, but at the same time, they are faced with the problems of extremely small particle size, large specific surface area, high surface energy, and easy agglomeration between particles. Therefore, dispersion stability is still the key to the application of nanoparticles in tribology. For example, most of the wear particles of internal combustion engine lubricating oil are nanoparticles, because they cannot be well dispersed in the lubricating oil, and the particles formed after agglomeration not only cannot resist and reduce wear, but will promote wear. In addition, the nanoparticles without surface modification were directly added to the base oil, and after being forcibly dispers...
