摘要
为提高相变调温防护服的阻燃性能,以保障工作人员的生命安全,系统开展阻燃型相变微胶囊涂层织物的制备与阻燃性能研究。选取2种相变温度的相变微胶囊、2种阻燃基布,利用干法涂层工艺制备相变微胶囊涂层织物;选取2种阻燃剂,以45%和75%的比例涂覆在相变微胶囊涂层的表面,制成16种阻燃型相变微胶囊涂层织物。基于锥形量热仪进行涂层织物阻燃性能测试,分析阻燃剂对涂层织物阻燃性能的影响。结果表明:与未进行阻燃整理的涂层织物相比,有机硅阻燃剂涂层织物的总热释放量平均下降42.22%,磷氮型阻燃剂涂层织物的总热释放量平均下降25.07%,并且随着阻燃剂含量的增加,总热释放量呈下降趋势。另外,有机硅型阻燃剂明显降低了热释放速率与总热释放量,而磷氮型阻燃剂有效地延长了织物开始释放热量的时间和热释放速率达到峰值的时间。因此,2种阻燃剂从不同角度优化了相变微胶囊涂层织物的阻燃性能,提高了相变调温防护服的使用安全性。
In order to improve the flame-retardant performance of protective clothing with phase change thermoregulation and guarantee the life safety of workers,the preparation of fabrics coated by flame-retardant phase change microcapsules(PCMs)and the research on flame-retardant performance were systematically carried out.The PCMs with two kinds of phase change temperatures and two kinds of flame-retardant fabrics were selected,and the PCMs coated fabrics were prepared by using the dry-method coating technique.Two kinds of flame retardants were coated on the surface of PCMs coating with the proportions of 45%and 75%,and 16 kinds of fabrics coated by flame-retardant PCMs were obtained.The tests on the flame-retardant performance of PCMs coated fabrics were carried out by using the cone calorimeter,and the effect of flame retardants on the flame-retardant performance of PCMs coated fabrics was analyzed.The results showed that compared with the coated fabric without flame-retardant finishing,the total heat release amounts of the coated fabrics with organic Silicon type coating and Phosphorus-Nitrogen type coating decreased by 42.22%and 25.07%averagely,and with the increase of flame retardant content,the total heat release amount presented the decreasing trend.Besides,the flame retardant of organic Silicon type significantly reduced the heat release rate and total heat release amount,while the flame retardant of Phosphorus-Nitrogen type effectively delayed the initial time for releasing heat and the time for reaching the peak heat release rate.Thus,two types of flame retardants improved the flame-retardant performance of PCMs coated fabrics from different perspectives,and increased the usage safety of protective clothing with phase change thermoregulation.
