摘要
以可发性聚苯乙烯(EPS)、酚醛树脂(PF)为主要原料,按一定的配比,添加适量的助剂,采用正交设计法设计制备EPS/PF复合型保温隔热材料的试验方法。用极差分析的方法讨论了压缩比、阻燃剂用量、固化温度以及保压时间对样品导热系数、阻燃性能、抗压强度以及吸水率的影响。筛选出最佳工艺条件为压缩比为1.5,阻燃剂用量为30%,固化温度为95℃,保压时间为1h时,所制得的复合保温材料的导热系数为0.035W/MK;抗压强度为0.21MPa;阻燃性(氧指数)为36%;吸水率为1.5%。
The composite thermal insulation material was prepared based on expandable polystyrene （EPS）, phenolic resin （PF） and additives by using the orthogonal design method. The influence factors such as the compression ratio, the curing temperature on the properties of composites were discussed by range analysis method. The results showed that the optimized conditions for the composite preparation are that when the compression ratio is 1.5, flame retardant agent was 30%, the curing temperature is 95 ℃, holding time of lh. The composite thermal insulation material coefficient of thermal conductivity is 0.035 W/M.K; Compressive strength is 0.21 MPa; Flame retardant （oxygen index） was 36%; water absorption rate is 1.5%.
