Development of A Novel Volatile Corrosion Inhibitor Paper without Nitroso-group

The inhibition performance of several volatile corrosion inhibitor papers was evaluated by electrochemical impedance method and some traditional methods.It is shown that these papers all have protection effect against carbon steel corrosion.The anticorrosive performance of 1# paper containing composite aromatic carboxylate is better than that of traditional volatile corrosion inhibitor paper containing sodium nitrite.The electrochemical impedance method is effective and convenient for the evaluation of inhibition performance of volatile corrosion inhibitor papers.
