The article presents a very simple method of synthesis and application of a halogen and formaldehyde free, P, S and Si-containing flame retardant for the durable finishing of cotton fabric. The compound was obtained as a result of the thiol-ene click reaction. The compound was designed to have two functional groups: an alkoxysilyl group for cross-linking and binding to the cotton fabric, and a phosphate group to provide flame retardant properties. The flame retardant was applied to cotton fabric using the sol-gel method. According to the pyrolysis-combustion flow calorimetry (PCFC) technique, the use of the obtained silane for cotton treatment can reduce heat release rate (HRR) to almost 75% compared to the raw fabric. FT-IR analyses and SEM images indicate that impregnated cotton samples were covered with a layer of silanes. The SEM-EDS analysis confirmed successful modification of cotton fabrics. After 10 cycles of washing it was found that the created coatings are resistant to washing and retain their flame retardant properties.
本文介绍了一种非常简单的合成方法及应用，该方法用于合成一种不含卤素和甲醛、含磷、硫和硅的阻燃剂，用于棉织物的耐久性整理。该化合物是通过硫醇-烯点击反应得到的。该化合物设计有两个官能团：一个用于交联并与棉织物结合的烷氧基硅烷基团，以及一个提供阻燃性能的磷酸基团。采用溶胶-凝胶法将阻燃剂应用于棉织物。根据热解-燃烧流动量热法（PCFC）技术，与未处理的织物相比，使用所得硅烷处理棉织物可将热释放速率（HRR）降低近75%。傅里叶变换红外光谱（FT-IR）分析和扫描电子显微镜（SEM）图像表明，浸渍后的棉样品表面覆盖有一层硅烷。扫描电子显微镜-能谱（SEM-EDS）分析证实了棉织物改性成功。经过10次洗涤循环后发现，形成的涂层耐洗涤并保留其阻燃性能。
