摘要
综述了近年来聚乙烯醇阻燃改性的研究概况,其改性方式可分为物理共混法和化学反应法,物理共混法是目前研究较多的方法。对主要无卤阻燃剂做简单归类,介绍阻燃机理及其在聚乙烯醇阻燃改性的应用,总结不同阻燃剂对聚乙烯醇的阻燃性能和力学性能的影响。提出充分利用聚乙烯醇富含羟基的结构特点,深入研究化学反应法,探索简单有效的工艺;提出应满足绿色可持续发展理念,采用生物基阻燃剂。
Reviews the research progress on flame retardant modification of polyvinyl alcohol in recent years.The modification methods include physical blending and chemical reaction.More research has been focused on physical blending.Classifies the main halogen-free flame retardants,and introduces the flame retardant mechanism and application in the flame retardant modification of polyvinyl alcohol.The flame retardants determine the flame retardancy and mechanical properties of modified polyvinyl alcohol.It is proposed to study chemical modification by utilizing the hydroxyl rich structural characteristics and explore simple and effective processes.Research about bio-based flame retardant should be developed to meet environmental protection.
