国内烟用水基胶改性研制进展

Advances in modification of water-based adhesives for cigarette manufacturing in China

  • 摘要: 为使科研人员了解烟用水基胶的研究现状及便于后续产品的研制,从国内烟用水基胶的分类、改性、上机适用性等3个方面进行了系统的梳理和总结,并对烟用水基胶的未来发展进行了展望。结果表明:①烟用水基胶主要有聚乙酸乙烯酯乳液水基胶、乙酸乙烯酯-乙烯共聚乳液水基胶和淀粉类水基胶3类。②合成高分子类水基胶的改性主要有共聚反应和物理混合两种方式,淀粉类水基胶的改性主要通过化学反应来实现,涉及氧化、酯化、交联或接枝等反应过程。③淀粉类水基胶及改性制品和具有增香、阻燃等辅助功能水基胶的研制是创新发展的重要方向。④国内需要加强水基胶上机适用性方面的研究。

     

    Abstract: In order to understand the current status of water-based adhesives for cigarette manufacturing and to facilitate further research for product improvements, the classification, modification and machine adaptability of water-based adhesives in China were systematically reviewed. The future prospect of the water-based adhesives was discussed. The results showed that: 1) The water-based adhesives used in cigarette industries mainly included polyvinyl acetate emulsion, vinyl acetate-ethylene copolymer emulsion, and starch-based water-based adhesives. 2) Modification methods of synthetic polymer-based water-based adhesives mainly included copolymerization and physical mixing. Modification of starch-based water-based adhesives could be achieved through targeted chemical reactions, involving oxidation, esterification, cross-linking or grafting reactions, etc. 3) The modified starch-based water-based adhesives, and water-based adhesives with auxiliary functions such as flavoring or flame-retardant might be an important innovative direction in the future. 4) Research on machine adaptability of water-based adhesives for cigarette manufacturing should be strengthened.
