摘要
为探究氢氧化铝作为防腐填料对地聚合物防腐涂层性能的影响,对不同氢氧化铝掺量下涂层的附着力、韧性以及防腐性能进行测试.试验结果显示:在氢氧化铝掺量为2％时,涂层的综合性能最佳,附着力为1.39 MPa,韧性为6 mm,经过氯盐浸泡15 d、干湿循环15 d、盐雾试验7 d后,腐蚀面积比最小,相较于空白对照组分别下降了 20.05％、27.25％、38.91％.试验可为地聚合物防腐涂层后续的研究及性能提升提供参考.
Abstract
In order to investigate the effect of aluminum hydroxide as anticorrosive filler on the performance of geopolymer anticorrosive coatings,the adhesion,toughness,and anticorrosive properties of the coatings were tested in this paper with different dosages of aluminum hydroxide.The test results show that:in the aluminum hydroxide doping of 2％,the comprehensive performance of the coating is the best,the adhesion is 1.39 MPa,toughness is 6 mm,and the corrosion area ratio is the smallest after 15 d of chlorine salt im-mersion,15 d of dry and wet cycle,and 7 d of salt spray test,which decreased by 20.05％,27.25％,and 38.91％compared with the blank control group,respectively.The test can provide a reference for the sub-sequent research and performance enhancement of the geopolymer anticorrosion coating on biotite base.
