【摘要】：采用高能电子束辐射方法引发丙烯酸(AA)单体接枝到聚丙烯(PP)纤维上,制备了一种新型烟用滤嘴材料PP-g-AA,研究了AA体积分数及辐照温度对接枝率的影响。采用傅里叶变换红外光谱(FT-IR)和扫描电子显微镜(SEM)对PP纤维接枝AA前后的表面化学组成和形貌进行分析。结果表明,PP-g-AA滤嘴纤维对主流烟气中的总粒相物、烟碱和焦油以及酚类化合物的截留效果显著提高。当AA接枝率为12.14%时,主流烟气中总粒相物的含量降低了23.6%;烟嘴过滤效率达到65.7%;焦油和烟碱的含量分别降低了29.5%和21.4%;有效改善了对苯酚、邻/间/对二苯酚、邻/间/对甲酚7种酚类化合的吸附性能,尤其对强致癌物邻苯二酚的吸附容量提高了102%。
[Abstract]:A novel cigarette filter material PP-g-AAwas prepared by grafting acrylic acid (AA) onto PP / PP fiber by high energy electron beam radiation. The effects of AA volume fraction and irradiation temperature on grafting rate were studied. The surface chemical composition and morphology of PP fiber before and after grafting AA were analyzed by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM). The results showed that PP-g-AA filter fiber could significantly improve the retention of total particulate matter, nicotine, tar and phenolic compounds in mainstream flue gas. When the grafting ratio of AA was 12.14, the content of total particle phase in mainstream flue gas was reduced by 23.6kW, the filter efficiency reached 65.7%, the tar and nicotine contents decreased by 29.5% and 21.4wt%, respectively, and the p-phenol, o-diphenol / 1 / 1 p-diphenol was effectively improved. The adsorption capacity of 7 kinds of phenols, especially for catechol, a strong carcinogen, was increased by 102g / m / p-cresol / p-cresol (p-cresol) / p-cresol (p-cresol).
