摘要
采用含磷阻燃剂和含氮阻燃剂复配的膨胀阻燃体系对涤纶织物进行阻燃整理,优化了阻燃整理工艺,并对处理织物性能进行表征。优化工艺为:含磷阻燃剂和含氮阻燃剂质量比为3∶1,阻燃剂总用量为20%,焙烘温度为170℃。采用该阻燃工艺处理的涤纶织物具有较好的抗熔滴性,其LOI值可达29.6%,断裂强力下降幅度小于5%。热失重、差示扫描量热法和扫描电镜(SEM)分析表明,阻燃处理后的涤纶织物在燃烧过程中分解温度提前,形成了膨胀型炭层,残炭量大幅提高。
An intumescent flame retardant （IFR）system containing phosphorus and nitrogen is applied to polyester fabric. The finishing process is optimized and the properties of treated fabric are characterized. The optimum process is as follows： mass ratio of phosphorus and nitrogen constituent 3 ： 1 ,the total dosage of IFR system 20% ,curing at 170 ~C. The treated PET fabric is imparted good resistance to melt drop and its LOI reached to 29.2 with breaking strength loss less than 5%. Characterization of the thermo-gravimetric analysis,differential scanning calorimetry （DSC） and SEM indicates that much more residual char with intumescent structure is formed during combustion of polyester fabric, whose decomposition temperature is lower compared to that of the untreated sample.
