壳聚糖基阻燃剂的研究进展

壳聚糖基阻燃剂具有绿色可持续发展的特点,符合阻燃剂未来的发展方向。在国内外学者对壳聚糖基阻燃研究基础上,系统介绍了壳聚糖基阻燃剂近年来的研究进展,即单组分壳聚糖阻燃剂、复合型壳聚糖阻燃剂、化学改性壳聚糖阻燃剂。单组分壳聚糖阻燃剂能在一定程度上提高聚合物的热稳定性,但不能提高材料的阻燃等级。壳聚糖复合型阻燃剂的主要研究方向是绿色复配含磷物质的应用,新型复配技术的探索,纤维制品层层自组装技术的深入开发。在纤维、塑料等制品领域,根据阻燃要求和材料的适应性进行分子设计,获得具有高效阻燃、共混适应性、整理耐洗性等特点高分子材料是化学改性壳聚糖阻燃剂的未来发展方向。

Research progress of chitosan-based flame retardants

The chitosan-based flame retardants have the features of green sustainable development and meet the future development direction of flame retardants. On the basis of chitosan-based flame retardant studies carried out by domestic and foreign scholars, research progresses in recent years about chitosan-based flame retardants described as monocomponent, blended, or chemically modified were systematically introduced. Monocomponent chitosan flame retardants can improve the thermal stability of the polymer materials and yet not the flame retardant grade of them. The main research directions for the future of the blended chitosan flame retardants are the applications of phosphorus-containing substances, the investigation of new blending technology and deep development of layer-by-layer self-assembly techniques of fibres products. Polymer materials with characteristics of high flame retardancy, blending adaptability and finishing washability can be obtained by means of molecular designing according to the needs of flame retardancy and blending adaptability in the fields of fibers or plastic products, which is the development trend of studies on chemically modified chitosan retardants.
