改性GPA降低纸-醋二元复合滤棒卷烟主流烟气中苯酚释放量的研究
Study on the reduction of phenol release in mainstream cigarette smoke containing paper-cellulose acetate binary filter by the modification of GPA

摘要: 将β-D-葡萄糖五乙酸酯(GPA)分别与5种黏性材料共混制备水性涂布材料,根据黏度、固含量和实验室评价结果筛选出最佳黏性材料并对共混质量比进行优化,对最优改性GPA水性涂布材料进行卷烟应用评价。结果表明:最优黏性材料为PEG600,且当GPA与PEG600的质量比为1∶1时,实验室综合评价效果最佳;使用涂布材料后的涂布纸定量、滤棒质量和压降均有所增加,但卷烟烟支质量和吸阻仅略微增加,其他参数则变化较小;涂布卷烟主流烟气中总粒相物和焦油均释放量均略低于未涂布样品,其烟碱释放量、水分、抽吸口数均与未涂布卷烟相同;相比于未涂布卷烟,涂布卷烟主流烟气中苯酚释放量降低率为47.1%,其他6种有害成分均有一定程度的降低,但降低幅度不大;此外,涂布卷烟感官品质与未涂布卷烟也无明显差异。

Abstract: Waterborne coating materials were prepared by blending β-D-Glucose pentaacetate(GPA) and 5 kinds of viscous materials. The viscous material with the best effect was selected according to the viscosity, solid content and laboratory evaluation results, and the blending mass ratio was optimized. After that, the application evaluation of the best modified GPA waterborne coating material for cigarette was carried out. The results showed that PEG600 was the best viscous material and the material with m(GPA)∶m(PEG600)=1∶1 had the best laboratory comprehensive evaluation effect. And the use of coating material resulted in the increase of coating paper weight, filter weight and pressure drop, but the cigarette weight and draw resistance increased only a slight, while the changes of other parameters were very little. Besides, the total particulate matters and tar in the mainstream smoke of the coated cigarette were slightly lower than those of the uncoated cigarette, meanwhile, the nicotine release, moisture and puff number in the mainstream smoke of the coated cigarette were the same as those of the uncoated cigarette. Comparing with the uncoated cigarette, the phenol in the mainstream cigarette smoke of the coated cigarette reduced by 47.1%, and the other six harmful components all have a certain degree of reduction which was not large. Moreover, the sensory quality of the coated cigarette and the uncoated cigarette had no significant difference too. -
