Abstract

The invention provides a fullerene-carbon nanotube lubricating additive and preparation of the fullerene-carbon nanotube lubricating additive and belongs to the field of lubricating additives, aiming at solving the technical problem of an existing water-based lubricating agent that the stability is poor, the cost is high, the lubricating performance is poor and the like. The preparation is realized through the following steps: 1, preparing water-soluble polymer modified fullerene; 2, preparing water-soluble polymer modified carbon nanotubes; 3, preparing the fullerene-carbon nanotube water-based lubricating additive. According to a water-soluble lubricant prepared from the water-based lubricating additive provided by the invention, the production cost can be reduced, the utilization stability is improved and the environment pollution is reduced; meanwhile, the water-soluble lubricant has a good lubricating performance and can be applied to a plurality of fields including micromechanical lubrication, waterborne cold rolling liquid and the like.

Description

technical field [0001] The invention relates to a preparation method of a water-soluble lubricating additive. Background technique [0002] In recent years, the use of carbon nanomaterials as lubricant additives has attracted increasing attention. With the development of the petroleum industry, oil-based lubricant technology is becoming more and more mature, and it is widely used in various industrial sectors. However, the world needs to consume about 40 million tons of oil for it every year, accounting for about 2% of oil production. With the world's energy crisis and the emphasis on environmental protection around the world, people began to prefer water-based low-pollution lubricants. Substituting water for oil can not only save oil resources, but also reduce production costs and reduce environmental pollution. Water-based lubricants can be divided into two types: solvent-based and emulsified. Emulsified-type lubricants have disadvantages such as difficulty in lubricati...
