| Abstract: |
| The fire safety of ceramic flame retardant and fire resistant silicone rubber composites with added ceramic powder W5 was investigated by vertical combustion test method，fire resistance simulation test method and cone calorimeter analysis method，and compared with flame retardant silicone rubber composites with added aluminum hydroxide.The results showed that the ceramic powder W5 after special surface treatment（CFR-2） could efficiently and high-quality produce ceramics from silicone rubber composites，significantly improve the flame retardancy and fire resistance of the composites.After combustion，the composites formed high strength ceramic bodies，the ignition time of the composites with added CFR-2 was prolonged，the heat release rate，total heat release，CO and CO2 releases and smoke production decreased，the combustion residue was dense and intact，and the fire hazard level was low. |
