摘要:本研究探讨了纤维原料组成对卷烟烟气成分分析用过滤材料过滤阻力和过滤效率的影响，进一步研究了过滤材料的增强工艺。结果表明，在未添加胶黏剂的情况下，使用纤维直径0.5~1.0 μm和纤维直径10~20 μm的玻璃纤维按照质量比58∶42抄造的过滤材料，过滤效率为99.970%，过滤阻力为330 Pa，满足过滤效率≥99.9%、过滤阻力≤360 Pa的过滤性能要求，但抗张强度较差；当浆内添加4%的自制丙烯酸乳液和0.4%的聚酰胺环氧氯丙烷（PAE）时，过滤材料抗张强度可达到1.01 kN/m，此时过滤效率为99.980%，过滤阻力为345 Pa。过滤材料过滤性能达到了进口产品的水平，满足ISO 3308（或GB/T 16450）标准的要求。

Abstract:The influence of fiber raw material composition on the filtration resistance and filtration efficiency of the filter pad for cigarette smoke composition analysis was discussed. Furthermore， the filter pad reinforcement process was studied. The experimental results showed that when glass fibers with diameters of 0.5~1.0 μm and 10~20 μm were used with the mass ratio of 58∶42，the filtration efficiency of filter pad without adding adhesive could reach 99.970%， and the filtration resistance was 330 Pa，which could meet the requirements of 99.9% filtration efficiency and 360 Pa filtration resistance， but the tensile strength was poor. When 4% homemade latex and 0.4% PAE were added， the tensile strength of filter pad could reach 1.01 kN/m with the filtration efficiency of 99.980% and the filtration resistance of 345 Pa.The filtration performance of the filter pad could reach the level of imported products and conform to the requirements of ISO 3308 （or GB/T 16450） standards.
