【目的】探究搭口胶的热解产物对烟气品质及其感官质量的影响。【方法】采用红外光谱（FTIR）、热重（TGA）、热重-红外联用（TG-FTIR）、热解光电离质谱（Py-SPI-MS）、元素分析和气相色谱-质谱联用（GC-MS）等技术，对10种卷烟搭口胶样品的成分及热解产物进行分析，并对这10种搭口胶制成的卷烟样品的烟气指标和感官质量进行评价。【结果】（1）10款搭口胶主要成分均为醋酸乙烯酯与乙烯的共聚物，在空气中热分解温度集中在330℃～400℃，其中9#、10#搭口胶样品中含有酰胺类添加剂，在220℃时会热裂解释放氨气等物质；（2）使用9#、10#搭口胶制作的卷烟样品在模拟燃烧条件下产生的氨气含量分别为7.8μg/支和7.5μg/支，较其他搭口胶制成的卷烟样品略高，主流烟气的感官刺激性增强，口腔舒适性下降，浓度和劲头有所提升。
Abstract：[Objective] This study aims to investigate the impact of pyrolysis products of tipping paper adhesive on smoke quality and sensory quality of cigarettes. [Methods] Fourier transform infrared spectroscopy(FTIR), thermogravimetric analysis(TGA), thermogravimetric analysis-Fourier transform infrared spectroscopy(TG-FTIR), pyrolysis-soft photoionization mass spectrometry(Py-SPI-MS), elemental analysis, and gas chromatography-mass spectrometry(GC-MS) were used to analyze the composition and pyrolysis products of 10 cigarette tipping paper adhesive samples. The smoke indicators and sensory quality of cigarette samples made with these 10 tipping paper adhesives were evaluated. [Results](1) The main components of the 10 tipping paper adhesives were all copolymers of vinyl acetate and ethylene, and their thermal decomposition temperatures in the air were concentrated in the range of 330℃～400℃. Among them, samples 9# and 10# contained amide additives, which would thermally crack and release ammonia and other substances at 220℃;(2) The ammonia content produced under simulated combustion conditions in cigarette samples made with 9# and 10# tipping paper adhesives were 7.8 μ g/cigarette and 7.5 μ g/cigarette, respectively, which were slightly higher than those made with other tipping paper adhesives. The sensory irritation of the mainstream smoke was enhanced, the oral comfort was reduced, and the concentration and strength were improved to some extent.
