摘要: In this article, dihydroxy polydimethylsiloxane (n = 5–10) was introduced into the structure of polyphosphate (PPE) to get siloxane-modified (SiPPE). Five kinds SiPPEs with different Si contents were obtained. FTIR (Fourier Transform Infrared spectroscopy) ICP (Inductively Coupled Plasma Emission Spectroscopy), 31P NMR (Nuclear Magnetic Resonance Spectroscopy) and TGA (Thermogravimetric Analysis) used characterize composition PPE SiPPEs. Six transparent fire-resistive coatings prepared by mixing amino resin five The results fire protection test showed that both time intumescent factor char layers increased increase in content Si. demonstrated carbonaceous residue coating also regularly. hardness, flexibility, digital photos, SEM (Scanning Electronic Microscopy) other testing introduction silicon oxygen segment can effectively improve crack resistance. charcoal layer more solid than before collapse not obvious after long flame shock. © 2015 Wiley Periodicals, Inc.
