聚磷酸铵杂化纳米SiO2溶胶的制备及阻燃性能研究
Study on the preparation and flame retardancy of ammoniumpolyphosphate hybrid nano-silica sol
摘要
Abstract
Ammonium polyphosphate hybrid nano-silica sol was prepared by sol-gel method using tetraethyl orthosilicate and ammonium polyphosphate as raw materials and applied to flame retardant finishing of cotton fabric,which combined the good film forming ability of nano-silica sol with the excellent flame retardancy of ammonium polyphosphate.The structure and morphology of the hybrid silica sol were characterized by fourier transform infrared spectroscopy(FT-IR),X-ray diffraction (XRD),transmission electron microscope(TEM) and scanning electronic microscopy(SEM).The hybrid nano-silica sol stability at various dosage of ammonium polyphosphate and flame retardancy of finished cotton fabric were studied.The results of FT-IR and XRD showed that ammonium polyphosphate hybrid nano-silica sol was prepared successfully,and the results of TEM and SEM showed that the diameter of sol particle size was about 50 nm and distributed uniformly.When the dosage of ammonium polyphosphate was 5.00%,the hybrid silica sol had good stability,and the cotton fabric treated by the hybrid silica sol had the best flame retardancy.关键词
