为解决传统阻燃剂在添加量大和协效性差的问题上, 新型复合阻燃剂成为目前阻燃剂领域的研究热点。核壳结构新型阻燃剂因具有良好的基体相容性及协同阻燃效应, 是一种对聚合物进行阻燃改性的有效方式。总结了近年来具有核壳结构的氢氧化物、硅系、磷氮系、有机金属骨架及生物基5类阻燃剂的应用现状及阻燃策略, 最后对核壳结构阻燃剂的未来发展趋势进行展望。
In order to solve the problem of the large additive amount and poor synergistic effect of traditional flame retardants, new compound flame retardants have become a research hotspot in the field of flame retardants.New flame retardants with core-shell structure are an effective way for flame-retardant modification of polymers because of their good compatibilities with matrix and synergistic flame-retardant effects.The application status and flame-retardant strategies of five types of flame retardants with core-shell structure in recent years, such as hydroxide, silicon, phosphorus-nitrogen, organometallic framework and biological base, were summarized.Finally, the future development trend of flame retardants with core-shell structure was prospected.
