云母钛珠光颜料的制备工艺研究

Research on Preparation Technology of Titanium-mica Pearly Pigment

采用分步均相沉淀剂——尿素对加入云母钛珠光颜料光泽性能的影响因素进行了研究。结果表明:尿素与钛盐的质量比为2.5∶1～3.5∶1、pH值≈3、反应温度85℃、钛盐溶液质量分数10%、加料速度0.2mL/min、搅拌速度400r/min时,制备的云母钛珠光颜料珠光光泽等性能很好。

The influence of the preparation process on the titanium-mica pearly pigment by the homogeneous deposit method was studied, in which the urea was added in multi-step. The results showed that pearly pigment had high quality under the process parameters which were as follows： WCO（NH2）2∶vTiOSO4 was 2.5∶1 to 3.5∶1, pH value was 3, reaction temperature was 85℃, concentration of titanium salt solution was 10%, feeding speed was 0.2mL/min, and stirring speed was 400r/min.
