一种阻燃丙纶面料及其制备方法

本发明涉及一种阻燃丙纶面料及其制备方法，其特征是该面料可由如下方法制得：首先，将三聚氰胺与甲醛反应，制得反应液；然后，将反应液与磷酸二甲酯反应，制得制得含氮磷阻燃剂；将含氮磷阻燃剂与聚丙烯颗粒共混，纺丝，制得丙纶纤维；最后，将丙纶纤维进行纺纱，织造，制得阻燃丙纶面料。本发明制备的阻燃涤纶面料的初始极限氧指数达到了34％以上，属于难燃材料范围；经过10次水洗后，其极限氧指数没有明显下降，仍然达到了31％以上。本发明方法制备的阻燃丙纶面料具有较强的阻燃性，全部生产工艺简单，价格低廉，生产过程对环境污染小。 The invention relates to a flame-retardant polypropylene fiber fabric and a preparation method thereof, and is characterized in that the flame-retardant polypropylene fiber fabric can be prepared by the following method: firstly, reacting melamine with formaldehyde to prepare a reaction solution; then, reacting the reaction liquid with dimethyl phosphate to prepare a flame retardant containing nitrogen and phosphorus; blending the nitrogen and phosphorus-containing flame retardant with polypropylene particles, and spinning to obtain polypropylene fibers; and finally, spinning and weaving the polypropylene fiber to obtain the flame-retardant polypropylene fiber fabric. The initial limit oxygen index of the prepared flame-retardant polyester fabric reaches 34% o
