抽象的四乙氧基硅烷(TEOS)和γ-(甲基丙烯氧基)丙基三甲氧基硅烷(KH570)用于制备单二氧化硅(SIO 2)溶胶(SIO 2)SOL和二氧化硅-5'-腺苷单磷酸盐(AMP,Bio,Bio,Bio基物质)通过溶胶植物溶液通过溶胶溶液通过溶胶溶液。Then, the prepared series of sols were successively applied onto the cotton fabric (COT) surface through a dipping-baking method.傅立叶红外光谱(FTIR),X射线光电子光谱学(XPS),X射线衍射(XRD),扫描电子显微镜(SEM),能量分散光谱(EDX),热射仪分析(TGA),限制性氧气(limiming Oxygen Index(Loimi),loimi flams and Tiltrical limimity calorimantial calor calorimity calor calor calor calor clorim cal,Vft,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFT,VFTEFFFT(VFT) (CCT)用于表征功能组,表面元素组成,晶体结构,微观形态和表面元素分布,原始(RAW)和处理过的棉花织物的热稳定性和阻燃水平。Results show that the series of sols are successfully converted to gels and coated onto the cotton fabric surfaces.AMP-SIO 2 -KH570@COT显示出最佳的火焰粘贴率,最高的炭残留率(48.7%)(原棉织物的6.5倍),LOI值为27.7%(不易粘性水平)。It can self- extinguish with a char length of only 8.2 cm in a VFT.它显示总热量释放(THR)和峰值释放速率(PHRR)降低了3.8%和48.5%,并且在CCT中的点火时间最长(43 s)。用KH570修饰的SiO 2溶胶转换凝胶清楚地改善了与棉织物的界面兼容性,并有效地分离了热和氧气。These components show good synergistic flame-retardant effects.Meanwhile, the AMP gel pyrolyzes the phosphate group at high temperatures to accelerate the carbonization degrees of cotton fibers.
