摘要: 用电化学方法和红外光谱技术研究了1,4－丁炔二醇缓蚀剂在环氧涂料中缓蚀作用。结果表明：缓蚀剂的加入可以明显改变涂层的阻抗，当缓蚀剂加入量小于0.5mass%时，涂层的阻抗随着缓蚀剂量的增多而增大；对所测得的缓蚀涂层的交流阻抗数据进行似合并结合红外光谱分析认为，在基底和涂层之间生成了一层不完整的聚合物覆盖膜，在此基础上采用电化学技术探讨了此覆盖膜在涂层中的缓蚀机理。

Abstract：In this paper, corrosion inhibition of 1,4-butynediol in epoxy coatings was studied by means of electrochemical method and IR spectrum. Experimental results showed that the inhibitor obviously increases the corrosion- resistance of epoxy coatings. When the amount of 1,4-butynediol corrosion inhibitor is less than 0.5mass% in the coating, the impedance of coating increases with addition of the corrosion inhibitor. Through the impedance data which is fitted by ZSimpwin software and analysis of the IR spectrum, we suggest that the incomplete corrosion inhibitor film with double bonds is formed between coating and substrate. The inhibitor mechanism of the corrosion inhibitor film was also discussed by means of electrochemical method.

Key words： 4-butynediol epoxy coating Electrochemical method inhibition mechanism
