摘　　要：醋酸乙烯酯-乙烯共聚乳液(即VAE乳液)是目前最主要的卷烟胶原料之一。随着高速卷烟机设备的引进,卷烟车速从原来1000支/min提高至单机车速10000支/min,对VAE乳液的质量和性能要求也越来越高。由于在高速卷烟机运行过程中,卷烟纸的运行速度极高(约600~700m/min),除了严格的环保标准之外,还要求乳液具备流变稳定、初粘速度快等性能。本文针对应用在烟用水机胶的VAE乳液进行流变性能比较,追踪烟用水基胶用VAE乳液储存过程中的流变性能稳定性,通过在VAE乳液中添加聚乙烯醇及羟乙基纤维素,比较流变性能,追踪流变性能的影响因素,确认添加10%~15%固含量20%的PVA BP-17水溶液、固含量5%的羟乙基纤维素,综合性能最佳,可为高速烟用水基胶配方设计提供借鉴。Vinyl acetate-ethylene copolymer emulsion(VAE emulsion)is one of the most important cigarette gum raw materials at present.With the introduction of high-speed cigarette machine equipment,the speed of cigarettes has increased from the original 1000 cigarettes/min to 10000 ciga-rettes/min.The quality and performance of VAE emulsion are required to be higher and higher.As the running speed of cigarette paper is extremely high(about 600~700 m/min)in the running process of high-speed cigarette machine,besides strict environmental protection standards,the emulsion is re-quired to have rheological stability and fast initial viscosity.In this paper,the rheological properties of VAE emulsion used in cigarette water-based ad-hesive were compared,and the stability of rheological properties of VAE emulsion used in cigarette water-based adhesive during storage was tracked.By adding polyvinyl alcohol and hydroxyethyl cellulose into VAE emulsion,the rheological properties were compared,and the influencing factors were tracked.It was confirmed that adding 10%~15%PVA BP-17 aqueous solution with 20%solid content and 5%hydroxyethyl cellulose with 5%solid content had the best comprehensive performance,and it could be a high-speed cigarette.
