摘要: 采用KH560改性后的由传统水热法制备Ni Co-LDH和金属盐蚀刻的方式制备金属有机框架(MOF)衍生Ni Co-LDH分别作为协同填料和主填料同时加入环氧树脂(EP)基体中,进行二元填料对EP复合材料的阻燃性能和抑烟性能表现出双尺寸阻燃剂协同作用的探究,并通过锥形量热测试(CCT)和极限氧指数(LOI)测试进行检验。CCT结果表明,当MOF衍生Ni Co-LDH@KH560与Ni Co-LDH@KH560的添加比例为1∶1时,总热释放量最低,且平均有效燃烧热最高,燃烧效率最高,燃烧更加完全,有毒有害气体的产生量减少。且催化成炭效果也最好,与纯EP的热释放速率峰值(PHRR)相比,其PHRR降低了28.11%。EP复合材料的LOI均高于纯EP。综上所述,二元填料表现出的双尺寸阻燃剂的协同作用,为提高EP的火安全性能提供了一种新的方式。

Abstract: In this paper, Ni Co-LDH using the traditional hydrothermal method and Ni Co-LDH derived from metal-organic frameworks (MOFs) prepared by the metal salt etching method were used as synergistic and leading fillers after being modified with KH560. Both fillers were added to an epoxy resin (EP) matrix to investigate the binary fillers' flame retardancy and smoke suppression properties. The dual-size flame retardant mechanism of the stuffing was demonstrated through cone calorimetry testing (CCT) and limiting oxygen index (LOI) testing. The results of CCT show that when the ratio of MOF-derived Ni Co-LDH@KH560 to Ni Co-LDH@KH560 is 1∶1, the total heat release is the lowest, the average adequate combustion heat is the highest, the combustion efficiency is the highest, the combustion is more thorough, and the production of toxic and harmful gases is reduced. The catalytic carbon formation was also the best, and the PHRR of pure EP was 28.11% lower than the peak heat release rate (PHRR). LOI of EP composites was higher than that of pure EP composites. In conclusion, the combined action of two-size flame retardants presented by the binary fillers provides a new way to improve the fire safety performance of EP.
