摘　　要：基于铝合金自身的特性和高光加工质量的要求,以蓖麻油酸和甲氧基聚乙二醇为原料,合成一种聚醚多元醇酯润滑剂,再以马来酸酐合成物复配硼酸、三元羧酸为防锈剂,研制了一款新型的合成型高光切削液,对比研究了该合成型高光切削液与市面常见的进口和国产切削液的润滑性能、对铝合金的防腐蚀性、防锈性、消泡性和抗硬水性。结果显示:与进口和国产切削液相比,高光切削液的最大无卡咬负荷P_(B)值为735 N,优于进口切削液(686 N)和国产切削液(588 N);高光切削液的攻丝扭矩值最低,进口切削液次之,国产切削液稀释液的攻丝扭矩值最高,表明高光切削液具有更好的润滑性。24 h腐蚀试验表明高光切削液对铝合金的防腐蚀性为A级,达到进口切削液的水平,优于国产切削液。高光切削液的防锈性较好,消泡性优异,抗硬水性能佳。Based on the characteristics of aluminum alloy and the demanding requirements of high-gloss machining quality,a polyether polyol ester lubricant was synthesized using castor oil acid and methoxy polyethylene glycol as raw materials,and a new type of synthetic high-gloss cutting fluid was developed using a maleic anhydride composite of boric acid and ternary carboxylic acid as rust inhibitors.Comparative studies were conducted on the lubrication performance,corrosion resistance to aluminum alloy,rust prevention,defoaming,and hard water resistance of this synthetic high-gloss cutting fluid against commonly available imported and domestic cutting fluids on the market.Results showed that compared with imported and domestic cutting fluids,the maximum non jamming load P_(B) value of high-gloss cutting fluid was 735 N,which was better than imported cutting fluid(686 N)and domestic cutting fluid(588 N).The threading torque value of the high-gloss cutting fluid was the lowest,followed by the imported and then the domestic diluted cutting fluid,suggesting superior lubrication of the high-glosscutting fluid.The 24 h corrosion test showed that the corrosion resistance of high-gloss cutting fluid to aluminum alloy was grade A,which reached the level of imported cutting fluid and is better than domestic cutting fluid.Additionally,the high-gloss cutting fluid exhibited commendable rust prevention,excellent defoaming,and favorable hard water resistance.
