Percolation and catalysis effect of bamboo-based active carbon on the thermal and flame retardancy properties of ethylene vinyl-acetate rubber

摘要: The effect of percolation and catalysis bamboo-based active carbon (BAC) on the thermal degradation flame retardancy ethylene vinyl-acetate rubber (EVM) composites with intumescent retardants (IFR) consisting ammonium polyphosphate (APP) dipentaerythritol (DPER) has been investigated. vulcanization characteristics were analyzed by a moving die rheometer. Thermogravimetric analysis (TGA) fire behavior tests such as limiting oxygen index (LOI), vertical burning (UL 94), cone calorimetry used to evaluate properties EVM composites. Scanning electron microscopy (SEM) was study morphology residues addition BAC significantly increased maximum torque (MH) matrices. combination IFR can improve stability Moreover, enhance char residue promote formation network for IFR. current EVM/37IFR/3BAC composite achieved an LOI 33.6% UL 94 V-0 rating. PHRR, total heat release (THR), smoke (TSR) EVM/IFR/BAC greatly reduced compared EVM/40IFR. Also, mechanical EVMIFR/BAC increasing contents. physical between before after degradation, chemical during are responsible improved © 2015 Wiley Periodicals, Inc. J. Appl. Polym.
