英文摘要 | The incorporation of large loading of flame retardants generally causes embrittlement of materials. However, most of the rubbers and thermoplastic elastomers are flammable. Therefore, preparation of a flame retardant with potential toughening characteristics is urgently required for preparing materials with both good flame retardancy and toughness. The objective of the present work was to prepare a macromolecular flame retardant with good flexibility, that is, 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO)-modified epoxidized polybutadiene (EPB-DOPO) via a creative approach of two-step reactions. First, polybutadiene (PB) was partially epoxidized to generate EPB; second, the reactive flame retardant DOPO reacted with epoxy groups to generate EPB-DOPO. EPB-DOPO with three epoxidation degrees was prepared: EPB5%-DOPO, EPB10%-DOPO, and EPB15%-DOPO. The chemical structure of EPB-DOPO was confirmed with proton nuclear magnetic resonance (H-1 NMR) and Fourier transform infrared (FTIR) spectra. Thermogravimetric analysis (TGA) showed that EPB-DOPO had good thermal stability. EPB10%-DOPO and EPB15%-DOPO passed the UL-94 V-2 and V-0 rating, respectively, and the gas-phase flame retardation mechanism was deduced. The glass transition temperature (T-g) of EPB-DOPO prepared in this study was below -20 degrees C. Due to little char formation, EPB10%-DOPO and EPB15%-DOPO showed good resilience even after flame ignition. This study has provided a creative strategy to prepare a macromolecular flame retardant with good flexibility. |
