Lubricant Additive Component Significantly Improve The Anti-friction And Anti-wear Properties Of Water Jul 13, 2017

Lubricant Additive Component in the development process is worth mentioning is ZDDP. This compound was originally used to solve the problem of corrosion of copper-lead bearings, and later found that ZDDP also has excellent antioxidant and anti-wear properties, which makes ZDDP become the most popular anti-oxidation, anti-corrosion, anti-corrosion effect Lubricant Additive Component, has been applied for more than half a century. In the early 1960s, non-polymerized succinimide ashless dispersant was developed and applied abroad. It has excellent low temperature dispersion performance and has a significant effect in improving the low temperature sludge, thus effectively solving the problem of low temperature sludge. Succinate dispersant and metal detergent compound also has a synergistic effect, can significantly improve the use of lubricating properties, and reduce the additive dosage, which is a major breakthrough in lubricant additive technology. The late 1960s, foreign countries have been basically the main types of internal combustion engine oil Lubricant Additive Component, namely, metal detergent, ash dispersant and ZDDP become the engine engine oil three functional Lubricant Additive Component. In the 1970s, the researchers on the one hand the various types of Lubricant Additive Component for chemical structure adjustment and series of serialization, so that a single performance more features, and further study the compound effect of these Lubricant Additive Component, in order to meet the economic principles, Lubricant Additive Component have better overall performance. After the 1980s, Lubricant Additive Component on international markets were sold more in the form of composite Lubricant Additive Component, the reason for this.

Despite the poor dispersion stability and possible corrosion and other problems, the researchers are also trying to add graphene to water-based lubricants. Song et al. Prepared an oxidized graphene nanosheets that can be dispersed in water without any dispersant or modifier by the improved Hummers method. Tribological properties of the test found that this graphene additive can significantly improve the friction and wear properties of water, and the performance is better than carbon nanotubes. Under the 60 N load, the friction coefficient and the wear diameter of the 0.1% mass fraction of the graphene solution were reduced by 33% and 45%, respectively, compared to 0.5% by mass of the carbon monoxide aqueous solution.

And the like by grafting poly (2-methylaminomethacrylate) onto the surface of graphene to form a polymer by surface-initiated atom transfer radical polymerization. This method of polymerizing graphene by polymer can make the graphene have heat sensitivity, that is, by changing the temperature to achieve the selective dissolution of graphene. Stankovich and so on with graphene and isocyanate reaction, prepared a series of isocyanate functional graphene, and N, N-dimethyl carboxamide and other polar aprotic solvents for a long time stable and uniform dispersion. The above study laid the foundation for the dispersion of graphene in lubricating oil.

Nanotechnology has been with the information technology, biotechnology and known as the future of the most important, the core of the three major technologies. For the possession of nanotechnology and nano-materials, the United States, Europe and Japan, more than 30 developed countries and regions to develop their own development plans, and carried out nanotechnology technology activities. Nano-lubricating materials consist of nano-Lubricant Additive Component, base oils and other functional Lubricant Additive Component, which are considered to be one of the nanomaterials worthy of attention. The use of nano-technology, such as the synthesis of nano-detergents with ultra-high alkalinity, can also be used in the manufacture of lubricant Lubricant Additive Component. The production of stable and effective nano-detergents depends on the development of new generation surfactants.
