摘要
对云母钛珠光颜料的制备工艺进行了研究,得出制备云母珠光颜料的较佳条件为:pH值控制在2-2.5之间,反应温度90℃,钛盐质量分数10%,搅拌速率200 r/min,水解反应时间3 h,导晶促进剂质量分数为SnCl4(mol)/TiCl4(mol)=10%,煅烧温度为900℃,煅烧时间3 h.采用上述条件制备出的云母珠光颜料白度及珠光效果佳.
This paper studied on preparation process of the mica titanium nacreous pigment.We find the optimum preparing condition is the pH value control between 2~2.5,the reaction temperature 90 ℃,the titanium salinity 10%,stirred at the speed of 200 r/min,hydrolytic reaction time 3 h.Besides,the concentration of the promoter of leading the crystal used is SnCl4(mol)/TiCl4(mol) =10% and calcination temperature is 900 ℃ for 3 h.According the above conditions,the whiteness and bead luminosity effect of the mica pearly luster pigment obtained is best.
