Abstract
With the increasing social demand for fire safety, the development of efficient and environmentally friendly new flame-retardant materials has become a research hotspot in the field of materials science. To address the issues of high toxicity and poor stability associated with traditional flame-retardant materials, this study successfully prepared a novel inorganic-organic composite flame-retardant material guided by green environmental protection principles, using sol-gel technology combined with surface modification techniques. This material is based on siloxane and incorporates functionalized nanofillers to enhance its thermal stability and flame-retardant properties. The microstructure and performance of the material were systematically characterized using Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis, and cone calorimetry. Results indicate that the prepared composite material exhibits excellent thermal decomposition performance and low smoke release characteristics, forming a dense and stable char layer during combustion, which effectively suppresses the transfer of heat and gases. Compared with pure organic flame-retardant materials, the peak heat release rate of this composite material decreased by 42%, and the total heat release rate was reduced by 38%, demonstrating significant flame-retardant effects. This study not only proposes a green and efficient design strategy for flame-retardant materials but also provides theoretical support and experimental evidence for their practical applications in construction, transportation, and electronics. This achievement holds important implications for advancing flame-retardant materials toward high performance and environmental friendliness.
