湿法涂层工艺对阻燃商标布形貌及阻燃性能的影响

Effect of wet coating process on the morphology and flame-retardantproperties of anti-flaming trademark fabric

为提高聚酰胺湿法涂层织物的阻燃性能,将阻燃剂9,10-二氢-9-氧杂-10-磷杂菲-10-氧化物(DOPO)作为填料添加于聚酰胺湿法涂层浆料中。研究以DOPO为填料的聚酰胺湿法涂层工艺(涂层浆料放置时间、烘焙温度、相转变时间)对所制涂层织物服用性能和阻燃性能的影响,进而得出最佳湿法涂层工艺。结果表明:DOPO加入聚酰胺湿法涂层浆料后,商标布的最佳涂层浆料黏度为0.7 Pa·s,最佳相转变时间为15 s,最佳烘焙温度为100℃,所制阻燃商标布具有较佳的阻燃效果和手感。

In order to enhance the flame retardant properties of PA wet coating fabrics,the flame retardant 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide(DOPO)was selected as a filler to add into the wet coated polyamide slurry.This paper is focused on studying the impact of wet coated polyamide with DOPO as the filler(the storage time,baking temperature,phase transformation time of coating slurry)on the wearability and flame retardant properties of the coated fabric,so as to obtain the optimal wet coating process.The results reveal that after DOPO is added to the polyamide wet coating slurry,the optimal coating slurry viscosity of the trademark fabric is 0.7 Pa·s,the optimal phase transformation time is 15 s,and the optimal baking temperature is 100℃.The anti-flaming trademark fabric can achieve better flame-retardant efficiency and hand feeling.
