摘要：Zinc phosphate/benzotriazole (ZPB) corrosion pigments were synthesized by one step self-heating method. The ZPB pigments showed visible anticorrosion performance by enhancing the corrosion resistance of the epoxy coating effectively through electrochemical impedance spectroscopy test. The impedance activity of ZPB pigments was increased by 1275.5% and 196.5% compared to pure zinc phosphate (ZP) and benzotriazole (BTA) pigments, respectively. The super effect of anticorrosion mostly contributed to the one step self-heating method, which improved the stability of the pigments and reinforced the combination of pigments and epoxy coating by the plank martensite structure of ZPB pigment. This method could transfer the heat released during the synthesis of ZP to the dissolving of BTA by directly co-precipitation, realizing the heat of self-sufficient in one step. Moreover, ZPB pigments achieved complementary anticorrosion effect, for making up the loopholes of the single anticorrosion and achieving superior property in the initial of anticorrosion process. It is instructive for the synthesis and development of the anticorrosive pigment in the future. (C) 2017 Elsevier Ltd. All rights reserved.
