| Abstract: | Recent research progress in flame retardancy of rigid polyurethane foam/expandable graphite composites was reviewed.A detailed introduction was given on its preparation method,thermal degradation behavior as well as flammability properties including limited oxygen index,horizontal and vertical burning rates,heat release rate,weight ratio of CO/CO2 production,and carbonization performance.The influences of foam density,addition amount,particle sizes,encapsulation treatment of expandable graphite as well as the combination with other flame retardants on thermal stability and flammability of the foam composites were analyzed.Besides,the relative mechanism was discussed in depth. |
