Research On Green Water-based Lubrication Additives

The issues of environment and energy sources have become international hotspots nowadays. Because mineral oil-based lubricant wastes strategic resource, such as petroleum, and pollutes the environment, human being pays more and more attention to such lubricants. Looking for water-based lubricants that can place mineral oil-based lubricants, developing environmental friendly water-based lubricants, and widening the usage range of water-based lubricants stare us in the face. The paper departs from aspects of economizing the resource and protecting the environment, aims at problems that the lubricating capability of water-based lubricant is bad and it is easy to rust metals, according to the lubricating theory and molecular structure designing theory, and develops environmental friendly greenly water-based lubricating additives named OT series that possess favorable ability of anti-wear and reducing friction, excellent capability of resisting extreme pressure, and anti-rust function. In addition, to consider copper transferring, prepared additives OT1 being as the main body, the lubricant named OTC which has more excellent tribological performance has been worked out. In the paper the main innovation and research harvests are as follows: 1,The primary synthesis project combining with molecular structure identifying (HPLC-MS and infrared spectrometry) and tests of friction and wear, the synthesis channel was selected and perfected. Then we succeed in developing green water-based lubricating additives, OT series and OTC, which are provided with excellent lubricating capability and will not pollute the environment. 1% OTC water-based lubricant compared with the hydraulic pressure oil, N46, its carrying capacity is 77.6% more than N46, and its lubrication effect enhances more than 10%.2, The effect of the factors on the tribological performance of the green water-based lubricants OT and OTC were studied. The factors included different additive weight of lubricant, the load, and so on.3, The recombination effect of OTl, OTC, and the solid lubricants (such as, graphite, MoS2, and PTFE) was researched. The excellent synergetic effect between the water-based lubrication additives modified chemically and PTFE was found. The load-carrying capacity of OT1 lubricant blended with PTFE was up to 1049N, increased 41%, and the anti-wear property...
