纤维素纸沟槽滤嘴选择性降低卷烟烟气中有害成分

Selectively reducing harmful components in mainstream cigarette smoke with grooved cellulose paper filter

为选择性降低卷烟烟气中的有害成分,以纤维素纸为载体涂布功能材料OPTI(含氨基聚合物),制备OPTI纤维素纸功能滤嘴,考察其对卷烟烟气焦油和有害成分释放量的影响,并进行了卷烟烟气体外毒理学检测。结果表明:(1)功能滤嘴能够高效选择性降低卷烟烟气中有害成分巴豆醛和氰化氢(HCN)的释放量,材料OPTI上墨量为(13.0±0.5)g/m^2时,焦油增加0.3%,巴豆醛降低35.8%,HCN降低57.2%;随着纤维素纸上材料OPTI上墨量的增加,烟气中巴豆醛和HCN的释放量降低;滤嘴具有良好的减害稳定性,存放10周后仍对烟气有害成分有高效降低作用。(2)与对照卷烟相比,对于纤维素纸上涂布OPTI材料的试验卷烟,细胞存活率略有提高,细菌致突变性和诱发微核率无明显差异。(3)将材料PEG6(聚乙二醇600)与OPTI复配后制备滤嘴,卷烟烟气焦油降低3.1%,苯酚、巴豆醛和HCN分别降低23.7%、24.6%和46.3%,烟气危害性评价指数下降0.91,而卷烟内在抽吸品质未受到明显影响。PEG6与OPTI复配材料是一种比较理想的减害纤维素纸涂料。

In order to selectively reduce harmful components in mainstream cigarette smoke, functional cellulose paper filter was prepared by coating cellulose paper with a functional material, OPTI, which contained amino polymers. The effects of the prepared filter on the release of tar and harmful components in mainstream cigarette smoke were investigated under machine-smoking condition, and in vitro toxicology test of cigarette smoke was also conducted. The results showed that：1） The functional filter selectively reduced the release of crotonaldehyde and hydrocyanic acid （HCN） in cigarette smoke. When the coating rate of OPTI was 13.0±0.5 g/m^2, the release of crotonaldehyde and HCN decreased by 35.8% and 57.2%, respectively; while tar delivery only increased by 0.3%. With the increase of OPTI coating rate on cellulose paper, the release of crotonaldehyde and HCN was further reduced. Furthermore, the harmful component reducing ability of the functional filter was stable after storing for 10 weeks. 2） During in vitro toxicology test, the viability of cells exposed in the smoke of cigarette with a functional filter was promoted slightly comparing with the control, while bacterial mutagenicity and micronucleus frequency did not change significantly. 3） Another functional filter was prepared by coating cellulose paper with recombined functional material of OPTI and PEG6 （polyethylene glycol 600）, the mainstream smoke of cigarette with the OPTI/PEG6 filter showed the reduced release of tar, phenol, crotonaldehyde and HCN by 3.1%, 23.7%, 24.6% and 46.3%, respectively. The overall hazard index of the test cigarette was decreased by 0.91. Moreover, the sensory quality of cigarette was not significantly influenced. Therefore, the recombined material of OPTI and PEG6 may be an ideal coating material for selective reduction of these harmful components in mainstream cigarette smoke.
