摘　　要：通过实验筛选出能够解决甲醇汽油腐蚀金属腐蚀抑制剂,并探讨了其缓蚀机理。通过单因素实验筛选出单一的缓蚀剂,并对筛选出的缓蚀剂进行复配制得复合缓蚀剂。当试液pH=3,水浴温度T=40℃,复合缓蚀剂用量为200 mg/L时,缓蚀剂对金属试片有较好的缓蚀效果,缓蚀率可达到80%左右。该研究制得的金属腐蚀抑制剂对金属试片有很好的缓蚀效果。Through the experiment, to choose the metal corrosion inhibitor of the methanol gasoline, and the corro- sion mechanism is discussed. Through the single factor experiment, to select single corrosion inhibitor, and the sin- gle corrosion inhibitors were used to prepare the compound corrosion inhibitor. When test solution pH = 3, bath tem- perature T = 40℃, compound corrosion inhibitor content is 200 mg/L, the corrosion inhibitor has a very good effect on the metal specimens, industrial corrosion rate can reach 80%. The prepared metal corrosion inhibitor has a very good effect on the metal specimens.
