摘要: 为满足伪装涂料对基材表面着色的需求，本文采用溶胶–凝胶法在空心玻璃微球表面包覆钴蓝颜料，实现其表面着色的可控制备。通过调控热处理温度与钴蓝颜料用量，系统研究了不同工艺条件下包覆层的颜色及相组成变化。结果表明，当热处理温度较低(700℃)时，样品中出现了Co3O4杂质，导致其呈绿色；随着热处理温度的升高，杂质逐渐消失，样品呈现出典型的钴蓝色。此外，增加钴蓝颜料的用量也会使样品发绿，这主要是由于包覆层较厚、烧结不完全所致，需要延长热处理时间以实现充分结晶与显色。本研究为钴蓝颜料在复合微球及伪装涂料中的应用提供了工艺参考。
Abstract: To meet the requirements of camouflage coatings for substrate coloration, cobalt blue pigment was coated on the surface of hollow glass microspheres via a sol-gel method to achieve controllable surface coloring. By regulating heat-treatment temperature and pigment dosage, the changes in the coating color and phase composition under different process conditions were systematically investigated. The results show that at a relatively low heat-treatment temperature (700˚C), Co3O4 impurities were formed, causing the samples to appear green. With increasing temperature, the impurities gradually disappeared, and the samples exhibited the typical cobalt blue color. In addition, increasing the amount of cobalt blue pigment also led to a greenish appearance, which was attributed to incomplete sintering of the thicker coating layer, suggesting that a longer heat-treatment time is required for full crystallization and color development. This study provides process guidance for the application of cobalt blue pigments in composite microspheres and camouflage coatings.
