Preparation and Application of Talc-Fiber Composite Fillers in Paper-Making
A kind of composite filler was prepared by using talc, 85。SR softwood pulp and CPAM. The effects of talc-fiber composite fillers on paper were investigated. The results showed that the composite fillers mainly adsorbed onto the surface of external fibrillatioed fibrils. Compared with commercial talc, the paper wih composite fillers addition had higher tensile index. It also showed that the composite fillers had some negative influence on drainage effect, when compared with the blank samples. Composite fillers which were prepared at CPAM dosage 0.6% had better effects on preparation of high filler paper.
