卷烟降焦减害滤棒构件的制备及应用

Preparation and application of filter rod components for reducing tar and harm in cigarette

以添加石墨烯纳米分子的热可塑性弹体材料为基材,利用注塑成型机制备卷烟新型滤棒构件,将滤棒构件与醋纤滤棒进行三元复合后卷制复合滤棒卷烟样品,研究新型滤棒构件对卷烟主要物理指标、主流烟气中常规成分及7种有害成分的影响。结果表明:石墨烯对苯酚和苯并[a]芘具有明显的吸附性作用,对其他成分影响较小;与同规格醋纤滤棒卷烟相比,复合滤棒卷烟样品吸阻升高幅度为12.33%,滤嘴通风率和总通风率升高幅度分别为10.17%和10.22%;复合滤棒卷烟样品主流烟气中常规成分和7种有害成分释放量均有所降低,其中烟碱降低约36%,焦油降低约34%,有害成分一氧化碳、氰化氢、巴豆醛、亚硝胺的降低效果较为明显,分别降低约53%、50%、62%和78%,且复合滤棒卷烟样品危害性指数由10.28降低至平均4.95,说明该石墨烯异型滤棒构件具有明显的降焦减害作用。

A new type of cigarette filter rod component was prepared using injection molding mechanism which used thermoplastic elastomer material with added graphene nanomolecules as the substrate.The filter rod component was ternary composite with vinegar fiber filter rod and rolled into a composite filter rod cigarette sample.The effects of the new filter rod component on the main physical indicators of cigarettes,conventional components in mainstream smoke,and seven harmful components were studied.The results showed that graphene had a significant adsorption effect on phenol and benzo[a]pyrene,with little impact on other components;Compared with the same specifications of vinegar fiber filter rod cigarettes,the increase in suction resistance of the composite filter rod cigarette sample was 12.33%,and the increase in filter nozzle ventilation rate and total ventilation rate were 10.17%and 10.22%,respectively;The release of conventional components and seven harmful components in the mainstream smoke of composite filter rod cigarette samples had been reduced,with nicotine decreased by about 36%and tar decreased by about 34%.The reduction effect of harmful components carbon monoxide,hydrogen cyanide,crotonaldehyde,and nitrosamine was more significant,with reductions of about 53%,50%,62%,and 78%,respectively.The hazard index of composite filter rod cigarette samples had decreased on average from 10.28 to 4.95,the designed graphene shaped filter rod component had a significant effect on reducing tar and harm.
