腈纶纤维用Br-N-Sb高效复合阻燃剂研究

Study on Br-N-Sb high-efficient fire resistant agent and flame-retarded mechanism for acrylic fiber

腈纶是非常易燃的纤维,其阻燃研究具有非常重要的意义.本文中基于NaSCN溶剂路线制造腈纶的工艺,在单一阻燃剂性能研究基础上,优化出满足阻燃要求的B r-N-Sb高效阻燃剂,对其阻燃机理研究发现,阻燃效应主要来自于BTy与Sb2O3的协同作用.

Acrylic fiber is very inflammable, the study of fire-resistant agents for acrylic fiber is very important. In the paper, based on the preparation technique of acrylic fiber using NaSCN as solvent and the study of single-composition fire-resistant agents, a high -efficient composed Br-N-Sb flame-retarded agent is obtained. Its flame -retarded mechanism is discussed and the result shows that the fire-resistant effect results mainly from the cooperativity between BTy and Sb2O3.
