Abstract


With the development of science and technology and social progress, environmental protection has become an important topic of concern to all over the world in various fields, mineral-based lubricant products due to the poor performance of biodegradable, are facing serious challenges of environmental requirements. Since the 90s of last century, the environment-friendly lubricants become a research focus for the rapid development of the field of lubricant. Most modern lubricants constitute the base oil and additives, base oil is a major component of the lubricating oil, lubricating oil decisive impact on the environment or ecological factors, due to the use of mineral-based lubricants superior performance, low price, and is still occupied of market dominance, mineral-based lubricants biodegradation accelerator to guarantee excellent lubrication properties at the same time improve its biodegradability is the original intention of this article. The ethylenediamine derivatives easy biodegradation of long-chain fatty acids as raw materials, synthesized the four Imidazoliny promote the lubricants biodegradable lubrication additives, infrared spectroscopy were used to characterize the structure of the additive. Four-ball friction and wear tester, thermal gravimetric analysis, lubricant copper corrosion test, rust-proof test imidazoline additives tribological properties, thermal stability, anti-corrosive and anti-rust properties were investigated, and the use of Scanning electron microscopy and X-ray photoelectron spectroscopy (XPS) additive antifriction mechanism study investigated the synthesis of imidazoline impact on the performance of biological degradation of mineral oil additives and additives and ZDDP complex performance. The results show that: infrared spectroscopy additive molecule containing the imidazoline ring structure, synthesis product to achieve the desired purpose; four imidazoline type additive having good oil-soluble within the range of 2.5% of the added amount of; thermal stability test results show that the they have good thermal stability, can significantly improve the corrosion resistance and anti-rust performance of the liquid paraffin and the added amount of 1.0% was added to the liquid paraffin; suitable addition amount is added to the liquid paraffin, can better improve antiwear properties of the liquid paraffin, the microscope by scanning electron microscopy and X-ray photoelectron spectrometer analysis, may be additive preferably antiwear effect adsorption film is formed on the friction surface and, simultaneously, the additive liquid paraffin base oils of biological degradation of performance has been greatly improved, also showed good synergy with ZDDP complex, is a potential environmentally friendly lubricating oil additives.
