摘要:

通过机械共混法制备了聚对苯二甲酸乙二醇酯(PET)/聚丙烯酸钠(PAAS)/活性炭复合材料,并通过差示扫描量热仪(DSC)、X射线衍射仪(XRD)和高效液相色谱仪(HPLC)对复合材料的热性能、晶体结构和挥发性有机化合物(VOC)含量等进行研究与分析。结果表明,活性炭的加入能提高PET/PAAS/活性炭复合材料的结晶度,降低复合材料中的VOC含量;随着活性炭的加入,PET/PAAS/活性炭复合材料的熔点先降低后升高,断裂强度呈先升高后降低,且分别在活性炭添加量为0.75 %与0.2 5%时达到最大值;当活性炭含量为1.25 %时,复合材料的甲醛去除率达到94.4 %,乙醛去除率达到92.1 %,丙酮去除率达到80.2 %。

Abstract:

In this study, the PET/PAAS/activated carbon composites were prepared by a mechanical blending method, and their thermal properties, crystal structure and VOC content were investigated by means of differential scanning calorimetry, X?ray diffraction and high?performance liquid chromatography. The results indicated that the addition of activated carbon improved the crystallinity of the composites but reduced their VOC content. The melting point of the composites was found to increase at first and then tend to decrease with an increase of activated carbon content. The composites achieved the maximum melting point and breaking strength at the activated carbon contents of 0.75 and 0.25 wt%, respectively. When 1.25 wt% of activated carbon was incorporated, the composites exhibited a formaldehyde removal rate of 97.54 %, a acetaldehyde removal rate of 92.1 %, and a acetone removal rate of 80.2 %.
