| Abstract: | A new silicon-halogen synergistic flame retardant,tetrachloroethyl silicate,was synthesized by using silicon tetrachloride and ethylene oxide as raw materials.The effects of reaction time,reaction temperature and the amount ratio of reacting substances on product yield were discussed.The optimal conditions selected for the preparation of tetrachloroethyl silicate were n(silicon tetrachloride):n(ethylene oxide) 1∶4.2,reaction time 2h and reaction temperature 25-50 ℃.A percentage of product yield of tetrachloroethyl silicate of 98% was achieved under such conditions.The molecular structure of tetrachloroethyl silicate and its related performance measurements were determined by means of FTIR(Fourier Transform infrared spectroscopy),1H NMR(Proton Nuclear Magnetic Resonance) and LOI(limiting oxygen index). |
