摘要:

本文研究了以碳化法结合有机包覆制备纳米碳酸钙的工艺与性能。以氧化钙和二氧化碳为原料,柠檬酸为表面控制剂,并添加适量的分散剂对其进行表面改性,制备出有机改性的纳米碳酸钙。通过多种仪器手段对所制备的样品进行了形貌、粒径、元素、化学成分等定量与定性分析。结果表明,所制备的球形碳酸钙颗粒的粒径从十几纳米到几十纳米不等,存在软团聚现象,粒径分布窄,表面存在有离子键合的有机物。

Abstract: This research studied the preparation technology and properties of nanometer calcium carbonate by carbonization and organic coated method. Calcium oxide and carbon dioxide were used as raw materials, citric acid was used as the surface control agent, and appropriate amount of dispersing agent was used as surface modification to prepare organically modified nano-calcium carbonate. The product was quantitatively and qualitatively analyzed by a variety of instruments, such as the morphology of the sample, size, elements and chemical composition. The results showed that the prepared calcium carbonate’s average particle size was 60 nm; there was a slight soft reunion phenomenon; particle size distribution was narrow; surface has ionic bonded organic matter.
