摘要
以六氯环三磷腈(HCCP)、降解壳聚糖(JCH)及乙醇为原料,制备出一种降解壳聚糖含磷阻燃剂JCHP-2。将其应用于亚麻织物的阻燃整理,考察了JCHP-2的含磷量及用量对织物阻燃性能的影响并研究其耐洗性能;结果表明,当JCHP-2的含磷量为14.41at%、用量为12%时,亚麻织物垂直燃烧性能达到GB/T5455—1997 B1级标准,皂洗10次后仍能达到B2级标准,具有一定的耐洗性。对优化条件下整理的亚麻织物进行热重分析,结果表明,织物的初始裂解温度降低,800℃残炭量由6.57%增加至25.89%。说明JCHP-2对亚麻织物具有较好的阻燃作用。
A flame retardant containing phosphorus JCHP-2 was synthesized using hexachlorotriphosphazene（HCCP）,oligochitosan（JCH） and ethanol.Linen fabric was finished by the flame retardant.The effect of phosphorus content and reagent dosage on the flame retardancy of the finished fabric was discussed,and the durability was also tested.The results show that the finished linen fabric exhibited good flame retardancy,which could reach B1 level of GB/T5455—1997 when the dosage of JCHP-2 was 12% and the phosphorus content was 14.41at%.B2 standard was still met after 10 cycles of soaping.Thermal gravimetric analysis shows that the finished fabric＇ s initial decomposition temperature was lowered,and the residue at 800 ℃ increased from 6.57% to 25.89%.All the above results indicate that the linen fabric finished with JCHP-2 had good flame retardancy.
