摘　　要：为了实现制革污泥蛋白质的资源化利用、提高棉织物的阻燃性,以热碱法提取的制革污泥蛋白质为原料,合成了高效无卤棉织物阻燃剂FR-P(flame retardant-protein)。以二氰二胺为催化剂,将阻燃剂FR-P接枝在棉织物上。研究阻燃棉织物的热稳定性、阻燃性能,及其阻燃耐久性。结果表明,对比未处理的棉织物,经过阻燃整理的棉织物检测出新增的氮、磷元素,且阻燃棉织物离开火焰后迅速自熄。在700℃氮气氛围下,阻燃织物的残炭率达到了36.7%(质量分数),具有优异的热稳定性。热释放速率峰值从195.4 W/g降至53.6 W/g;极限氧指数从17%提升至35%。阻燃棉织物经过30次水洗后极限氧指数为28%,属于难燃织物,达到阻燃织物的B2标准。In order to realize the resource utilization of tanning sludge proteins and improve the flame retardancy of cotton fabrics.The high-efficien halogen-free flame retardant(FR-P:flame retardant-protein)for cotton fabrics was synthesized using tanning sludge protein extracted by a thermo-alkaline method as the raw materials.The flame retardant FR-P was successfully grafted onto cotton fabric using dicyandiamine as the catalyst.The thermal stability,flame-retardant properties and durability of the treated cotton fabrics were studied.The results showed that,compared with the untreated cotton fabrics,the newly added nitrogen and phosphorus elements were detected in the cotton fabrics after the flame retardant finishing,and flame-retardant cotton fabric quickly self-extinguished after leaving the flame.Under the nitrogen atmosphere at 700℃,the carbon residue yield of the treated cotton fabrics reached up to 36.7%,which had an excellent thermal stability.The peak heat release rate decreased from 195.4 W/g to 53.6 W/g and the limiting oxygen index increased from 17%to 35%.The limit oxygen index of flame retardant cotton fabric was 28%after 30 washing times,which was non-flammable fabric and achieved the B2 standard of flame retardant fabric.
