摘要
为提高金红石型钛白粉的应用性能,提出锆-聚乙二醇600复合包膜金红石型钛白粉。采用正交试验法研究包膜过程中搅拌速度、分散剂六偏磷酸钠的用量、氧氯化锆的用量和聚乙二醇600的用量对金红石型钛白粉性能的影响。利用Nano-zs电位仪检测包膜后金红石型钛白粉的Zeta电位,通过扫描电镜、透射电镜、沉降试验分析金红石型钛白粉包覆前后的效果。试验结果表明:搅拌的转速为300 r/min,六偏磷酸钠和氧氯化锆的质量分数分别为1.0%, 2%,PEG600的用量为0.005 mol/(100 g TiO2)是锆-聚乙二醇600复合包膜金红石型钛白粉的最佳工艺条件。
The rutile titanium dioxide was coated with Zr-PEG600 to improve its application performance. By means of orthogonal test method, the effects of the stirring speed, the dosage of SHMP, ZrOCl and PEG600 on titanium dioxide in the performance were explored. The Zeta potential of rutile titanium dioxide was examined by Nano-zs potential instrument, and the surface effect of rutile titanium dioxide was observed by scanning electron microscopy（SEM）, transmission electron microscopy（TEM） and settlement test. The result showed that stirring speed of 300 r/min, 1.0% dispersant,2% ZrOCl, 0.005 mol/（100 g TiO2） PEG600 achieved the optimal process.
