中文摘要：
以碳酸钙为载体，利用机械力化学法在其表面包覆钛白粉，制备一种新型的复合填料．通过吸油值、遮盖力、粒径等参数和傅里叶变换光谱、扫描电镜等方法对复合填料样品进行表征，并对复合填料的特性及其对纸页性能的影响进行了研究．结果表明：碳酸钙在包覆后颗粒粒径增大，与钛白粉之间有化学键的生成，两者结合强度很好；复合填料的遮盖力和吸油值接近钛白粉；在灰分相同时，复合填料加填纸页的光学性能及物理强度接近钛白粉加填纸页，可以部分代替或者全部代替钛白粉．
英文摘要：
A new kind of composite filler was prepared by coating the carrier of calcium carbonate, with titanium dioxide via the mechanochemical method. Then, the structure of the composite filler was characterized by using such parameters as oil-absorbed values, hiding power and particle size and by means of FF-IR and SEM, and the properties of the composite filler and its effect on paper were then investigated. The results show that（ 1 ） the particle size of the composite filler is larger than the uncoated calcium carbonate; （2） the chemical bonds form between calcium carbonate and titanium dioxide and is of a good strength ; （ 3 ） the hiding power and the oil absorption values of the composite filler are close to those of titanium dioxide; and（4）at the same ash content, the optical properties and the physical strength of the paper filling with the composite filler are close to those of the paper filling with tita-nium dioxide, thus the composite filler being able to partly or wholly replace titanium dioxide.
