摘要: 本文借助于Ni2+氧化金属铝实现铝颜料表面的羟基化,以酚醚型磷酸酯(TXP-10)作为缓蚀剂制备了缓蚀型水性铝颜料.红外光谱(FTIR)和X射线衍射(XRD)测定表明,镍离子氧化金属铝在铝颜料表面形成勃母石结构的氧化铝的水合物,勃母石可吸附TXP-10达到缓蚀目的.探讨了反应介质组成及pH值、NiSO4?7H2O和TXP-10的用量等对缓蚀性能的影响.结果表明:40.00 g铝粉在中性的异丙醇/水的体积比为100/15的反应介质中,0.30 g NiSO4?7H2O羟基化作用下,吸附4.00 g TXP-10,可制得缓蚀性能最佳的水性铝颜料.

Abstract: The corrosion inhibition waterborne aluminum pigments were prepared by using NiSO4?7H2O oxidized aluminum to make the surface hydroxylation, and the phenol ether phosphate TXP-10 as the corrosion inhibitor. FTIR and XRD results indicated that nickel ion oxidized aluminum on the aluminum pigment surface formed the boehmite structure aluminum oxyhydroxide, and the boehmite can adsorbe TXP-10 to achieve the corrosion inhibition. The influence on corrosion inhibition by composition and pH value of the preparation medium, the dosage of NiSO4?7H2O and TXP - 10 were studied. The results showed that at neutral condition, 40.00 g aluminum pigment was oxidized by 0.30 g NiSO4?7H2O in the volume ratio of isopropyl alcohol/water = 100/15, and 4.00 g TXP-10 were adsorped, the waterborne aluminum pigments exhibited best corrosion resistance.

Key words: waterborne aluminum pigments, surface hydroxylated aluminum pigments, phenol ether phosphate, adsorption, corrosion inhibition
