摘要
为了以一种季铵盐类抗菌剂作为功能性助剂,制备具有一定抗菌性能的纸包装材料,并研究其性能。以硫酸盐针叶木浆为基材,以表面涂覆和湿部添加2种方式,加入不同质量分数的抗菌剂,通过热压工艺制备抗菌性纸包装材料,并对材料功能进行测试,从而确定最佳质量分数及工艺参数。结果表明抗菌剂质量分数、添加方式、工艺参数的选择与材料性能密切相关。以表面涂覆的方式、使用相比较绝干浆质量比为0.8 mg/g的抗菌剂、在热压温度为100℃下热压20 min的方案最优。
In order to use a quaternary ammonium salt as an antibacterial agent for,functional additives, antibacterial paper packaging materials were prepared and its performance properties were studied. Softwood kraft pulp as substrate, added different concentrations of antimierobial agents by using two ways of surface coating and wet end, prepared antibacterial paper packaging materials by means of hot pressing process, and tested the functional materials to determine the optimal concentration and process parameters. The result shows that antibacterial agent concentration, adding method, process parameter selection are closely related to material properties. Surface coating , antibacterial agent quality ratio 0. 8 mg/g compared to the oven dry pulp, hot pressing temperature 100 ℃, hot press time 20 minutes is the optimal solution.
