| Abstract: | 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 FT-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... |
