摘要:

为提高涤纶织物的阻燃性能和润湿性能,用2,4-二羟乙基胺-6-氯-1,3,5-三嗪与苯基磷酰二氯制备了含三嗪环的苯基磷酸酯结构的P-N型阻燃整理剂BPAT,并采用二浸二轧整理工艺对涤纶织物进行阻燃整理。通过比较整理前后织物的红外光谱、扫描电子显微镜、热力学数据、续燃和阴燃时间及润湿角,讨论了BPAT整理对涤纶织物阻燃性能的影响。结果表明:BPAT 可提高涤纶织物的残炭率超过3倍,降低织物燃烧的阴燃和续燃时间到0.2s和6.2s,对涤纶织物具有较好的阻燃效果;经10次水洗,整理织物的阻燃性略有降低,但降低程度不大,整理织物具有一定的阻燃耐久性。整理后涤纶织物的润湿性能明显改善。

Abstract:

In order to improve the flame retardancy and wettability of polyester fabric, the P-N type flame retarding agent BPAT with had phenyl phosphate structure containing 1,3,5-triazine was prepared using 2,4-diethanolamine-6-chloro-1,3,5-triazine and phenyl phosphorous oxydichloride. The flame retardant BPAT was used to treat polyester fabric by two-dip-two- pad finishing. The flame retardance of BPAT on the polyester fabric was investigated by infrared spectrum, scanning electron microscopy, thermal gravimetric analysis and burning properties of the treated and untreated polyester fabric. It is found that the char yield of polyester fabric is improved to over 3 times, and the afterflame time and smoldering time are dropped to 0.2 s and 6.2 s by the BPAT treating on fabric. The treated polyester fabric has good flame retardancy. The flame retardancy of the treated fabric slightly decreased after 10 times of water washing, and the treated fabric has flame retardant durability. The wettability of the treated fabric is increased by finishing with BPAT.
