摘　　要：采用不同的有机羧酸醇胺盐作为防锈剂与丙二醇嵌段聚醚酯消泡剂复配,制备了多功能金属加工助剂,并研究其消泡、防锈、润滑性能。结果表明:防锈剂分子中极性基团越多,防锈剂添加量越大,防锈性能越好;添加防锈剂会削弱金属加工助剂的消泡效果,消泡性能随防锈剂添加量的增加而减弱;水溶液pH值对防锈性影响较大,较高的pH值对防锈及抑制工作液的腐败有一定的积极作用,而pH值对消泡性能影响较小。正交试验结果表明:采用质量比为1∶2的三元羧酸(三己酸-6,6′,6″-三聚氰胺)醇胺盐和蓖麻油酸醇胺盐为复合防锈剂,聚醚酯与复合防锈剂质量比为2∶1时,制备的金属加工助剂不仅具有良好的消泡效果,还具备良好的防锈性。通过考察润滑性能发现,该金属加工助剂还能显著提高水的承载能力,表现出较好的极压、抗磨减摩特性及润滑稳定性。Multi-functional metal processing aids were prepared by using different alkanolamine salts of organic carboxylic acids as anti-rust agents to compound with propylene glycol block polyether ester defoaming agent,and their antifoaming,rust inhibition and lubricating properties were studied.The results show that the more polar groups in the anti-rust agent molecule,the greater the amount of anti-rust agent added,the better the rust inhibition performance.Adding antirust agent will weaken the defoaming effect of the metal processing aid,and the defoaming performance will weaken with the increase of anti-rust agent.The pH value of aqueous solution has a great influence on the rust inhibition property.Higher pH value has a positive effect on the anti-rust and anti-corruption of the working solution,while the pH value has less influence on the defoaming property.The results of orthogonal test show that when the ternary carboxylic acid(6,6′,6″-(1,3,5-triazine-2,4,6-triyltriimino)tris-Hexanoic acid)triethanolamine salt and castor oleic acid triethanolamine salt at the mass ratio of 1∶2 are used as compound anti-rust agent,the mass ratio of polyether ester and compound anti-rust agent is 2∶1,the metal processing aid prepared has good defoaming effect and good rust inhibition property.Through the investigation of lubrication performance,it is found that the metal processing aid prepared can significantly improve the carrying capacity of water,and shows good characteristics of extreme pressure,anti-wear and friction reducing,and good lubrication stability.
