| 目的 制备一种绿色高效复配气相缓蚀剂，用于金属的防锈包装。方法 选用苯甲酸钠(C7H5CO2Na)、葡萄糖酸钠(C6H11O7Na)、植酸(C6H18O24P6)和柠檬酸钠(C6H5Na3O7)为复配药品，以A3钢和45#钢为实验对象。通过密闭挥发减量实验、气相快速甄别实验电化学实验和湿热实验筛选出缓蚀率最高的复配气相缓蚀剂配方。将确定的最高缓蚀率气相缓蚀剂制成气相防锈纸，与防锈原纸、市售气相防锈纸进行防锈效果对照，对照实验采用扫描电子显微镜(SEM)、能谱仪(EDS)和接触角仪测试。结果 筛选出四元复配组11 g/L苯甲酸钠+11 g/L葡萄糖酸钠+15 g/L植酸+5 g/L柠檬酸钠的缓蚀率最高，对A3钢的缓蚀率达到了94.36%，对45#钢的缓蚀率达到了94.47%。经该防锈纸防护的A3钢和45#钢表面光滑，无锈蚀出现，氧元素含量低，且接触角大于90°，呈现明显疏水性。结论 经过4种缓蚀剂药品的复配筛选，最终确定出了缓蚀率最高的气相缓蚀剂配方为11 g/L苯甲酸钠+11 g/L葡萄糖酸钠+15 g/L植酸+5 g/L柠檬酸钠，且制成的复配气相防锈纸防锈效果优于空白组的防锈原纸以及市售气相防锈纸。 |

| In order to prepare a green and efficient compound gas phase corrosion inhibitor for metal anti-rust packaging. Sodium benzoate (C7H5CO2Na), sodium gluconate (C6H11O7Na), phytic acid (C6H18O24P6) and sodium citrate (C6H5Na3O7) were selected as compound drugs, and A3 steel and 45# steel were used as the experimental objects. The compound gas phase corrosion inhibitor formula with the highest corrosion inhibition rate was selected through the volatilization weight-loss test in closed space, the rapid gas phase discrimination experiment, the electrochemical experiment and the damp heat experiment. The vapor phase corrosion inhibitor with the highest corrosion inhibition rate was made into vapor phase rust prevention paper, and the rust prevention effect was compared with anti-rust base paper and commercial vapor phase anti-rust paper. The control experiment used scanning electron microscope (SEM) and energy spectrometer (EDS) and contact angle meter test. The quaternary compound group 11 g/L sodium benzoate+11 g/L sodium gluconate+15 g/L phytic acid+5 g/L sodium citrate had the highest corrosion inhibition rate, and the corrosion inhibition rate for A3 steel reached 94.36%. The corrosion inhibition rate of 45# steel reached 94.47%. The A3 steel and 45#steel protected by the anti-rust paper had a smooth surface, no corrosion, low oxygen content, and a contact angle greater than 90°, showing obvious hydrophobicity. After the screening, the gas phase corrosion inhibitor with the highest corrosion rate was finally determined as 11 g/L sodium benzoate+11 g/L sodium gluconate+15 g/L phytic acid+5 g/L sodium citrate, and the anti-rust effect of the prepared composite VCI paper is better than the anti-rust base paper of the blank control group and the commercial VCI paper. |
