摘　　要：以山梨醇和磷酸为原料合成山梨醇磷酸酯缓蚀剂,研究了葡萄糖酸锌(ZnGL)与山梨醇磷酸酯(SPA)的协同效应,并加入钼酸钠和聚天冬氨酸(PASP)提升缓蚀性能。实验结果表明:以SPA为主剂,ZnGL、钼酸钠、PASP为助剂复配得到四元复合缓蚀剂ZGPSM,在60℃模拟矿化水中的缓蚀率达到89.4%,与单独使用SPA相比,缓蚀性能更好,表明四者之间存在协同作用;ZGPSM在碳钢表面形成多种保护膜,为混合型缓蚀剂。A sorbitol phosphate inhibitor(SPA)was synthesized from sorbitol and phosphoric acid.The synergistic effect of zinc gluconate(ZnGL)and sorbitol phosphate was studied.The addition of sodium molybdate and polyaspartic acid(PASP)was found to improve the corrosion inhibition performance.Using SPA as the main agent,ZnGL,sodium molybdate and PASP as additives,a quaternary composite corrosion inhibitor(ZGPSM)was prepared.The corrosion inhibition rate of ZGPSM in simulated mineralized water at 60℃is 89.4%.Compared with the use of SPA alone,the corrosion inhibition performance of ZGPSM is better,indicating that there is a synergistic effect among the four components.The technical analysis shows that ZGPSM forms a variety of protective films on the surface of carbon steel,and the electrochemical results show that ZGPSM is a mixed corrosion inhibitor.
