摘　　要：本文利用淀粉、硬脂酸钠和六偏磷酸钠对重质碳酸钙(GCC)进行包覆改性,并对GCC改性前后相关性质的变化与使用效果进行探讨。实验证明,GCC改性前后其白度、不透明度、Zeta电位、粒度及分布等都发生较大的变化;在相同灰分条件下,改性GCC加填纸比未改性GCC加填纸具有更好的强度性质。In this paper, precipitated calcium carbonate（GCC） was modified by starch with the aid of sodium stearate and sodium hexametaphosphate. The property and using performance of modified GCC and GCC were studied. The results showed that the brightness, opacity, Zeta potential, and particle size distribution of GCC were changed after the modification by starch. The strength properties of paper added with modified GCC are mueh better than those added with unmodified GCC.
