摘要
采用分子设计方法制备了氮-磷-铝协同阻燃材料,并作为填料,通过阻燃赋性工艺引入皮胶原纤维之间,得到阻燃性能优良的阻燃功能皮革,并通过FTIR、^(1)H NMR、SEM、XPS、TG和DTG进行了表征。FTIR和^(1)H NMR表明已引入了目标结构,SEM、EDS和XPS表明阻燃填料已引入到皮革的胶原纤维束之间;TG和DTG表明,阻燃填料的添加量越大,皮革的热分解温度越高,残留率也越大;阻燃测试结果表明,引入氮-磷-铝阻燃剂后,皮革具有较好的阻燃性,不燃烧,离开火焰后极易熄灭,不续燃;燃烧距离几乎为零,基本无质量损失,阻燃等级可达到UL 94 V-0,极限氧指数可达到354%。
A M-THPS-Al synergistic flame retardant was prepared using molecular design,introduced as a filler between the leather collagen fibers by a designed flame retardant modification process,resulting in flame retardant functional leather with excellent flame retardant performance,and the structure was characterized by FTIR,^(1)H NMR,SEM,XPS,TG,and DTG FTIR and ^(1)H NMR show that the target structure is introduced SEM,EDS and XPS show that the flame retardant filler is introduced between the leather collagen fiber bundles TG and DTG show that the higher the addition of flame retardant filler,the higher the thermal decomposition temperature of leather,and the higher the residual rate Flame retardant testing results show that after introducing the M-THPS-Al flame retardant,leather has good flame retardant performance,does not burn,and easily extinguishes after leaving the flame,without continuous combustion The burning distance is almost zero,with almost no mass loss The flame retardant rating could reach UL 94 V-0,and the limiting oxygen index could reach 354%.
