摘　　要：采用液相沉积法制备云母钛珠光颜料,在制备单覆层TiO2/Mica的基础上再包裹一层Cr2O3得到双覆层云母钛,针对形成双覆层中探讨沉积过程的主要条件-煅烧温度和包覆剂滴加速度对反应形成覆层效果的影响,结果表明:当反应滴定速度为0.5mL/min,煅烧温度为800℃时达到最佳珠光效果。最后通过热重分析仪分析双覆层云母钛的稳定性良好。The titanium - mica single cladding TiO2/Mica coating pearlescent pigment was prepared by a Cr2o3 layer forming double cladding liquid phase deposition method, based on titanium -mica pearlescent pigment. The main condition in deposition process - - calcination temperature and dropping speed of coating agent was researched for those effects to cladding. The results shown that best pear｜escent effect was achieved at dropping speed was 0. 5mL/min and calcination temperature 800℃. Finally,the stability of double cladding titanium -mica was good as analyzed by thermo gravimetrie analyzer.
