摘要
Abstract
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.关键词
