| Popis: | 99 Ammonium salt was used to modify the nano mica and expandable graphite powder (EG) with the different particle sizes in this study. Furthermore, EG and mica were added into Methyl Methacrylate (MMA) to synthesize PMMA/EG/mica composites. The compression molding was used to fabricate the PMMA/EG/mica composites and carry on the various test of physical and chemical properties. Through the flame retardant testing results showed that PMMA/EG/mica composites with the same particle size and loadings have the better flame retardant performance. However, the composites with larger particle size EG have significant performance. Otherwise, the chemical properties variation was tested by FT-IR. Finally, the surface morphology of PMMA/EG/mica composites was observed by SEM and thermal properties analysis was used by DSC instrument. |
