摘要：

采用物理化学法,将实验室自制锌粉分别添加钛酸酯偶联剂、硅烷偶联剂和十二烷基苯磺酸钠进行表面改性，利用沉降法测试高度研究改性前后锌粉的分散稳定性。 结果表明，不同种类、不同浓度的表面改性剂对锌粉的分散稳定性有较大的影响；其中，经1.0%钛酸酯偶联剂改性后锌粉的分散稳定性有了明显的改善，与进口粉的分散稳定性接近。

关键词: 钛酸酯偶联剂, 硅烷偶联剂, 十二烷基苯磺酸钠, 分散稳定性

Abstract:

Zinc powders were firstly modified by mechanic-chemistry method using titanate coupling agent, silane coupling agents and sodium dodecylbenzenesulfonate. Their dispersion stabilities were investigated via measuring the height with the sedimentation method. The results showed that different species and concentrations of surface modifier have dramatic effects on the dispersion stability.The dispersion stability of the zinc powder modified by 1.0% titanate coupling agent was significantly improved and close to that of imported zinc powder.

Key words: titanate coupling agent, silane coupling agent, sodium dodecylbenzenesulfonate, dispersion stability
