【摘要】 本研究使用胶原蛋白与苯基膦酸进行反应，制备了磷氮协效阻燃剂胶原蛋白/苯基膦酸盐（POC）。使用浸渍烘干法将其整理到涤棉混纺织物（PTCO）上，详细研究了阻燃整理PTCO的微观形貌、热稳定性能、阻燃性能、燃烧行为、力学性能、抗菌性能及阻燃机理等。扫描电子显微镜图片表明POC均匀地沉积在PTCO的表面。空气氛围下PTCO/POC的Rmax降低了20.3%,700℃下的残炭由0.6%提升至3.3%。PTCO/POC在垂直燃烧中能够自熄，续燃时间与阴燃时间都为0 s，损毁长度为7.8 cm,LOI值为28.2%。在CCT测试中点燃时间由26 s延长至35 s，最大热释放速率与总热释放分别降低了33.8%和23.6%。此外，PTCO/POC保留了88.1%的断裂强力。PTCO/POC对大肠杆菌和金黄色葡萄球菌的抑菌率均达到了99.99%。综上所述，PTCO/POC兼具阻燃性能与抗菌性能。更多还原

【Abstract】 In this study, a P/N synthesized flame retardant,POC, was prepared by reacting collagen with phosphenylic acid (PPOA), and used to improve the flame retardancy of polyester cotton blended fabrics(PTCO) by the dip-drying method. A detailed study was conducted on the microstructure, thermal stability, flame retardancy, combustion behavior, mechanical properties, antibacterial properties, and flame-retardant mechanism of finished PTCO. The scanning electron microscope images indicated that POC was uniformly deposited on the surface of PTCO. The Rmax of PTCO/POC under air atmosphere decreased by 20.3%, and the char residues at 700 ℃ increased from 0.6% to 3.3%. PTCO/POC can self-extinguish, with an afterflame time and afterglow time of 0 s, a damaged length of 7.8 cm, and an LOI value of 28.2%. In cone calorimeter test, the time to ignition was extended from 26 s to 35 s, and the peak heat release rate and total heat release values were decreased by 33.8% and 23.6%, respectively. In addition, the breaking force of PTCO/POC was increased from 725 N of PTCO/PPOA to 810 N, remaining 88.1% of the breaking force compared with that of PTCO. The antibacterial rates of PTCO/POC against Escherichia coli and Staphylococcus aureus both reached 99.99%. In summary, PTCO/POC owned better flame retardancy and antibacterial properties.更多还原
