摘要
利用阴离子聚丙烯酰胺(APAM)、阳离子淀粉(CSt)和阳离子聚丙烯酰胺(CPAM)形成聚合电解质复合物并自发沉积包覆在造纸用研磨碳酸钙(GCC)表面,同时引起填料预絮聚从而完成填料的改性;将改性后的填料用于纸张加填并探究其对纸张物理性能的影响。结果表明:相比于未改性的碳酸钙,经APAM/CSt/CPAM三元体系改性的碳酸钙,平均弦长增大为初始填料的9倍,其加填纸的成纸灰分提高了2.2倍(灰分含量达到16.32%),且纸张的抗张强度维持不变。
The polyelectrolyte complex（PEC）,formed by combining anionic polyacrylamide（APAM）,cationic starch（CSt）and cationic polyacrylamide（CPAM）,coated and modified the ground calcium carbonate（GCC）with a dual mechanism of spontaneous deposition and filler flocculation.Subsequently,the modified filler was employed for paper filling to probe into its effect on the physical properties of paper.The results indicated that compared to the untreated calcium carbonate,the mean chord length of the calcium carbonate modified by APAM/CSt/CPAM was 9 times that of the original filler,and the ash content of filled hand sheet up to16.32%increased 2.2 times,while the tensile strength of the paper remained unchanged.
