摘要 通过对环境友好的氨基甲酸酯法共混磷氮系阻燃剂1,2-二(2-氧代-5,5-二甲基-1,3,2-二氧磷杂环己-2-亚氨基)乙烷(DDPN)和N,N′-二(5,5-二甲基-2-磷杂-2-硫代-1,3-二烷-2-基)乙二胺(DDPSN)纺制阻燃纤维素纤维,对纤维的力学性能和阻燃性能进行研究。结果表明:共混纤维的干态强度略低于粘胶纤维,而湿态强度、湿模量略高于粘胶纤维,该类阻燃剂在纤维素中的质量分数大于18%时,共混阻燃纤维的极限氧指数(LOI)大于25%,纤维达到了阻燃要求。 The flame retardant cellulose fibers were spun by an eco-friendly process, i.e., adding certain P-N containing flame retardants, 1,2-bis (2-oxo-5,5-dimethyl- 1,3,2-dioxyphosphacyclohexyl-2-imino) ethane (DDPN) and N, N'-bis (5,5-dimethyl-2-phospha-2-thio-1,3-dioxan-2-yl) ethylene diamine (DDPSN) to the carbamate solution, and the mechanical and flame retardant properties of the prepared cellulose fibers were studied. The results show that the dry tenacity is less than that of viscose fiber, but wet tenacity and wet modulus of the polyblend fibers are slightly higher than those of viscose fibers. When the mass fraction of this kind of retardants in the cellulose fibers is larger than 18% and the limiting oxygen index (LOI) of the polyblend flame retardant cellulose fibers is larger than 25 %, the fibers meet the flame retardant requirements.
