| 제목 | Synergistic effect of ATH and EVA/clay nanocomposites on flame retardation |
| 초록 | Layered silicate based nanocomposites are an important class of new materials for which a large set of properties can be greatly improved, when compared with classical fillers at the same filler content. In this work, flame retardant EVA/clay nanocomposites were prepared by direct melt intercalation of EVA, organophilic clay and conventional flame retardants like ATH and MDH. Morphology and flame retardation properties were characterized by X-ray diffraction(XRD), scanning electron microscopy (SEM), limiting oxygen index (LOI), vertical burning test (UL-94) and cone calorimeter experiments. The flame retardant nanocomposites with MDH showed lower peak heat release rate (HRR) and higher LOI than that of ATH. But EVA/clay nanocomposites with ATH showed a delayed ignition time. The delayed ignition time is considered as a critical reason for the improvements of UL-94 (vertical burning) test result. Reference 1.
