【摘要】 研究了纳米LDH(水滑石 )和纳米Mg(OH) 2 无机阻燃剂对环氧树脂、聚氯乙烯、聚乙烯电缆料及尼龙 6 /聚丙烯体系的阻燃效果。结果表明两者对环氧树脂、聚氯乙烯的抑烟效果极为显著 ,纳米Mg(OH) 2 对聚乙烯有很好的阻燃效果 ,可使氧指数上升 16 %以上 ;纳米LDH与APP(聚磷酸铵 )复配 ,可获得对PA 6 /PP共混物的协同阻燃效果。更多还原

【Abstract】 The flame retardancy effects of Layered Double Hydroxide (LDH) nanomaterials and magnesium hydroxide nanomaterials on epoxy resin (EP),polyvinyl chloride (PVC) and polyethylene (PE) in wire and cables and polyamide-6 (PA-6)/polypropylene (PP) blends were investigated.The results showed that LDH and Mg(OH) 2 exhibited excellent smoke suppression with EP and PVC.The addition of Mg(OH) 2 to PE increased oxygen index by 16%.There was found to be a synergistic effect between LDH and ammonium polyphosphate (APP) fire retardants in PA-6/PP blends.更多还原
