液相沉积法制备单覆层云母钛珠光颜料的研究

PREPARATION OF THE NACREOUS PIGMENT OF MICA TITANIUM WAS PREPARED BY LIQUID PHASE DEPOSITION(LPD)

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.
