摘要
采用亚磷酸二甲酯与顺丁烯二酸酐为原料,合成亚麻阻燃剂PX;以自制的降解壳聚糖和PX为底物,合成了新型亚麻织物阻燃整理剂JPX,用电位滴定法测定其取代度。对PX和JPX整理后织物的续燃时间、阴燃时间、损毁长度、白度和断裂强力等性能进行测试,结果表明:当JPX取代度为0.682,JPX质量分数为20%,浴比为1∶20,焙烘温度为160℃,焙烘时间为3 min时,亚麻织物的阻燃性能较好,其续燃时间为0.6 s、阴燃时间为0.7 s、损毁长度为2.5 cm。
Flame retardant PX for linen cloth is prepared with dimethyl phosphonate and maleic anhy- dride as raw materials. Then a new flame retardant JPX for linen fabric is synthesized by self-made de-- graded chitosan and PX as substrates. The substitution degree of JPX is determined by potentiometric ti- tration. The after-flame time, afterglow time, damaged length, whiteness and breaking strength of flame retardant fabric with PX or JPX respectively are tested. The results show that： when substitution degree of JPX is 0.682, JPX concentration is 20%, bath ratio is 1：20, curing at 160 ℃ for 3 min, the flame retardant linen fabric features good flame retardant property with 0.6 s of after-flame time, 0.7 s of after- alow time. and 2.5 cm of damaged length.
