Development of a Total Synthetic Cutting Fluid for Nonferrous Metals

报道了一种性能优异的有色金属全合成切削液的研制.以硼酸和三乙醇胺为原料合成三乙醇胺硼酸酯作为极压润滑剂的主要成分,以癸二酸与三乙醇胺为原料合成防锈剂,再将其与杀菌剂、表面活性剂等复配研制成有色金属全合成切削液.采用四球机法对其进行润滑性能测试;采用单片防锈法、叠片防锈法、Tafel极化曲线测试等方法进行防锈性能测试,并通过扫描电镜观察了金属形貌变化.结果表明,研制的有色金属全合成切削液具有优异的极压润滑性、防锈性和生物稳定性.

This paper reports the development of a kind of excellent total synthetic cutting fluid for nonferrous metals.Boric acid and triethanolamine are used as the raw materials to synthesize triethanolamine borate,which serves as the main component of the extreme-pressure lubrication agent,and decanedioic acid and triethanolamine are adopted to produce the rust inhibitor.Then they are combined with the antiseptic agent and the surface active agent to prepare the total synthetic cutting fluid for nonferrous metals.A lubrication performance test is carried out using a four-ball machine,and its anti-rust properties are checked by means of the single chip and the lamination methods,and the Tafel polarization curve test.The morphology of the metal is observed by a scanning electron microscope.The results show that the developed total synthetic cutting fluid has excellent extreme-pressure,antirust properties and biological stability.
