【摘要】 使用经丙酮处理的莫代尔纤维,在铈离子存在的条件下,与丙烯酸(AA)发生接枝聚合反应,确定了反应最佳条件,之后再经过碱化,铝化,制备出丙烯酸阻燃的莫代尔纤维。利用傅里叶红外光谱(FTIR)、扫描电镜(SEM)、热重分析(TG)、极限氧指数测试(LOI)、微型量热等表征测试手段对阻燃莫代尔纤维进行测试表征。结果表明:经过丙烯酸交联接枝后,莫代尔被赋予了阻燃性,其极限氧指数达到31%。更多还原

【Abstract】 The acetone treated Modal fibers are graft copolymerized with acrylic acid in the presence of cerium ions, the optimal conditions for the reaction are determined. Afterwards, they are alkalized and aluminized to form acrylic flame-retardant Modal fabrics. The flame retardant Modal fabrics are characterized by Fourier transform infrared(FTIR), scanning electron microscopy(SEM), thermogravimetric analysis(TG), limiting oxygen index test(LOI)and microcalorimetric technique(MCT). The results show that after cross-linking with acrylic acid, the modal is endowed with flame retardance, its limiting oxygen index reaches 31%.更多还原
