| 摘 要： | 通过聚苯乙烯(PS)与氧化石墨烯(GO)共混,制备聚苯乙烯/氧化石墨烯(PS/GO)保温建筑材料,并对PS/GO阻燃性能以及保温性能进行研究。结果表明:GO含量为6%时,4号样品的综合性能最好。4号样品的LOI值为33.4%,阻燃等级达到V-1,热释放速率峰值(pHRR)为525.76 kW/m2,总产烟量(TSP)为629.37 m2。此外,4号样品具有较低的导热系数0.034 2 W/(m·K),并且吸水率以及水蒸气透过系数均满足标准值,说明其可以有效应用于建筑保温材料。

| Abstract: | Polystyrene/graphene oxide(PS/GO) thermal insulation building materials were prepared by blending polystyrene(PS)with graphene oxide(GO), and the flame retardancy and thermal insulation properties of PS/GO were studied. The results show that when the GO content is 6%, the comprehensive performance of sample 4 is the best. The LOI value of sample 4 is 33.4%, the flame retardant grade reaches V-1, the peak heat release rate(pHRR)is 525.76 kW/m2,and total smoke production(TSP)is 629.37 m2. In addition, sample 4 has a low thermal conductivity of 0.034 2 W/(m·K),and water absorption and water vapor permeability meet the standard values, indicating that it can be effectively used in building insulation materials. |
