以硅酸钠溶液为成膜基料，锌粉为颜填料，去离子水为溶剂，加入增稠剂，固化剂等助剂，制备钠水玻璃富锌涂料；应用红外光谱分析、流变学测量和耐液性观察，研究钠水玻璃富锌涂料的固化机理。结果发现，其固化机理主要是硅酸之间的脱水反应和锌离子对硅酸的交联；流变学测试显示，粘度随温度的上升先减后增，随时间增加；用光学显微镜观测固化后的富锌涂膜分别在水、稀酸和碱溶液中浸泡后的状态变化，定性应证了这个机理。

Using sodium silicate solution as the binder of zinc-rich coating, zinc powder as the filler, distilled water as the solvent, and adding thicker, solidifier, sodium silicate inorganic zinc-rich coatings were prepared. After that, the curing mechanism of the coating were studied through Fourier transform infrared spectral analysis, rheologieal measurement and solution-resistance observation. They also indicated that the curing mechanism of sodium silicate inorganic zinc-rich coating was mainly due to the chemical crosslinking between sodium sili...
