摘要:以二胺型苯并噁嗪为前驱体,通过浸涂和热固化的方法在低碳钢表面制备了聚苯并噁嗪涂层。二胺型聚苯并噁嗪涂层具有良好的成膜性,并对低碳钢基体具有良好的附着力。采用动电位极化测试和交流阻抗测试考察了固化温度对聚苯并噁嗪涂层防腐蚀性能的影响。结果表明:不同固化温度制备出的聚苯并噁嗪均具有良好的防腐蚀效果;其中,固化温度为150℃时所制备的涂层防腐蚀性能最佳,腐蚀电流为1.49×10^(-8) A/cm^2,相比空白低碳钢样品的腐蚀电流(6.91×10^(-6)A/cm^2)下降了2个数量级。
Diamine-based polybenzoxazine (Poly(Ph-mda)) coatings were prepared on mild steel (MS) through a simple dip coating and thermal curing method using diamine-based benzoxazine as precursor.Poly(Ph-mda) showed good film-forming property and adhesive ability on MS surface. The effectemperature on anticorrosion property of polybenzoxazine films was investigated by Tafel curves andelectrochemical impedance spectroscopy (EIS) measurements. The results revealed that Poly (Ph-mda)coated MS samples exhibited high anticorrosion performance. When the curing temperature samples showed the best anticorrosion properties with the corrosion current of 1. 49Xdecreased two orders of magnitude compared with that of bare MS (6. 91X10-6 A/cm^2).
