摘要
为实现高电导率下的纸张增强,利用三聚氰胺甲醛树脂改性醋酸酯淀粉,制备出了改性的淀粉增强剂,并对改性工艺及增强性能进行了研究.结果表明,利用三聚氰胺甲醛树脂对醋酸酯淀粉进行改性,可以有效地提高醋酸酯淀粉对纸张的增强性能;当湿部体系电导率较低时,改性醋酸酯淀粉对纸张的增强性能略低于阳离子淀粉,而高电导率条件下改性醋酸酯淀粉的增强性能则优于阳离子淀粉.
In order to improve the strength of paper under the condition of high electrical con-ductivity,the modified starch acetate with melamine formaldehyde resin was prepared.The effect of modifying methods,temperature,time and dosage of melamine formaldehyde resin were studied.The application property of modified starch acetate was researched too.The re-sult was shown that the application property of starch acetate can be effectively improved by the melamine formaldehyde resin.When the electrical conductivity of wet end system was lower,the strength properties of paper enhanced by modified starch acetate were slightly in-ferior to that of cationic starch.But the strength properties of paper enhanced by modified starch acetate were superior to that of cationic starch when the wet end system was higher.
