一种绿泥石基复合钛白粉及其制备方法
摘要：
本发明提供了一种绿泥石基复合钛白粉及其制备方法，本发明的复合钛白粉通过在绿泥石表面包覆纳米二氧化钛颗粒及纳米氧化铝颗粒得到，并由以下重量份数比的组分制成：绿泥石60～70份，二氧化钛15～30份，氧化铝1～5份，分散剂0.5～5份；本发明所述的绿泥石基复合钛白粉通过沉积、洗涤过滤以及煅烧步骤制备而成；通过本发明获得的绿泥石基复合钛白粉具有成本低、白度高、分散性好、吸油值低、水溶盐值低的特点。
摘要（英）：

The invention provides chlorite-based composite titanium dioxide powder and a preparation method thereof. The composite titanium dioxide powder disclosed by the invention is prepared by coating nanometer titanium dioxide particles and nanometer aluminum oxide particles on the surface of the chlorite and is prepared from the following components in parts by weight: 60-70 parts of chlorite, 15-30 parts of titanium dioxide, 1-5 parts of aluminum oxide and 0.5-5 parts of a dispersing agent. The chlorite-based composite titanium dioxide powder disclosed by the invention is prepared by the steps of deposition, washing and filtering, and calcining. The chlorite-based composite titanium dioxide powder obtained by the preparation method disclosed by the invention has the characteristics of low cost, high whiteness, good dispersity, low oil absorption value and low water-soluble salt value.
