Preparation of A Cationized Pulp and Its Application as a Wet-end Additive in the Papermaking Process
Cationized pulp fibers(CPF)were prepared by the adsorption of a novel biodegradable cationic ester quaternary ammonium salt(31441)on bleached softwood kraft pulp fibers.The optimized conditions for the CPF preparation were: 4％ of 31441(based on oven-dry pulp),80℃ and 30 minutes.The CPF was characterized by FT-IR,SEM and XPS.Experimental results with the CPF as a wet-end additive showed that the CPF could improve the retention of precipitated calcium carbonate(PCC)filler significantly.With 0.9％ CPF(based on oven-dry pulp),the retention of PCC increased from 57.53％ to 72.21％.The physical properties of paper were also slightly improved.The tensile strength and burst strength of the paper with CPF were higher than those with CPAM.CPF addition had no effect on the stock drainage.
