In this study, core-shell structured piperazine pyrophosphate (PAPP) is designed to enhance the fire safety and mechanical property of styrenic thermoplastic elastomer (TPE) composites. The PAPP is microencapsulated with carbon nanotube modified melamine-formaldehyde resin to prepare core-shell structured flame retardants (MT@PAPP). Due to the excellent compatibility between the MT@PAPP and TPE matrix, the mechanical property of TPE/MT@PAPP is improved. Compared with TPE, the peak heat release rate and peak smoke production rate of TPE/MT@PAPP are decreased by 78.5% and 60.0%, respectively. Thus, the core-shell structured piperazine pyrophosphate microcapsule strategy provides an excellent approach to obtain high-performance TPE composites.
在本研究中，设计了核壳结构的焦磷酸哌嗪（PAPP）以提高苯乙烯类热塑性弹性体（TPE）复合材料的消防安全性能和机械性能。用碳纳米管改性三聚氰胺-甲醛树脂对PAPP进行微胶囊化，制备核壳结构阻燃剂（MT@PAPP）。由于MT@PAPP与TPE基体之间具有优异的相容性，TPE/MT@PAPP的机械性能得到改善。与TPE相比，TPE/MT@PAPP的热释放速率峰值和产烟速率峰值分别降低了78.5%和60.0%。因此，核壳结构的焦磷酸哌嗪微胶囊策略为获得高性能TPE复合材料提供了一种优异的方法。
