摘　　要：将抗菌剂以浆内添加的方式加入纸基渗水材料中,用以延长纸基渗水材料的使用寿命,研究添加抗菌剂N–(2–苯并咪唑基)氨基甲酸甲酯(MBC)和亚甲基双硫氰酸酯(MBT)的纸基渗水材料在不同土壤环境中力学性能、质量损失率、聚合度以及表面形貌的变化,分析了抗菌剂抑制材料性能劣化的机理。结果表明:MBC和MBT对纸基渗水材料的力学性能、聚合度、质量损失率的下降均有一定抑制作用,且MBC的抑制效果优于MBT。与空白样相比,材料中添加0.05%MBC时,抗张指数在田园土中由6.41 N·m/g提高到16.03 N·m/g,在沙土中由9.31 N·m/g提高到17.15 N·m/g;材料中添加0.07%MBC时,质量损失率在田园土中由25.53%降至4.10%,在沙土中由23.65%降低至2.06%。添加0.05%MBC时,材料的聚合度下降程度由26.09%降至15.64%。In order to prolong the service life of paper-based permeable materials,the mechanical properties,mass loss rate,polymerization degree and surface morphology of paper-based permeable materials with antibacterial agents methyl 2-benzimidazole carbamate(MBC)and methylene bis(thiocyanate)(MBT)were studied in different soil environments,and the mechanism of antibacterial agents inhibiting the deterioration of material properties was analyzed.The results showed that MBC and MBT inhibited the mechanical properties,polymerization degree and mass loss rate of paper-based permeable materials,and the inhibition effect of MBC was better than that of MBT.Compared with the blank sample,when 0.05%MBC was added to the material,the tensile index increased from 6.41 N·m/g to 16.03 N·m/g in the field soil and from 9.31 N·m/g to 17.15 N·m/g in the sandy soil;when 0.07%MBC was added to the material,the mass loss rate decreased from 25.53%to 4.10%in the field soil and from 23.65%to 2.06%in the sandy soil.The degree of polymerization decreased from 26.09%to 15.64%when 0.05%MBC was added.
