- Abstract
This article examines the feasibility of intumescent flame retardant (based on phosphorus acid, melamine, and pentaerythritol) as a flame retardant and FeO as a smoke suppression agent in silicone rubber (SR) composites. Smoke suppression of FeO on intumescent flame-retardant SR composites was investigated using smoke density test and cone calorimeter test (CCT). And, the flammability of SR composites was characterized using CCT at an incident heat flux of 50 kW m. The test results further revealed that FeO could increase smoke suppression efficiency and thermal degradation temperature. FeO can promote early cross-linking of polymer during decomposition to increase char formation. The silica ash layer integrity governs the efficiency of diffusion barrier that restricts the diffusion of fuels into combustion zone and access of oxygen to the unburned fuels.
