摘　　要：在35kW/m^2热辐照条件下,利用锥形量热仪研究了膨胀型阻燃剂/Mg(OH)_2阻燃高密度聚乙烯(HDPE)体系的燃烧性。结果表明：膨胀型阻燃剂/Mg(OH)_2能明显降低HDPE的热释放速率、总热释放量、最大生烟速率及总烟释放量。与膨胀型阻燃剂单独使用相比,Mg(OH)_2与膨胀型阻燃剂复合使用的阻燃效果明显,总烟释放量减少了38%,总热释放量减少了10%,达到了低发烟、高效阻燃的目的。The flammability of high density polyethylene (HDPE) treated with the intumescent flame retardant containing Mg(OH)2 was investigated by using a conical calorimeter under thermal radiation of 35 kW/m2 in this paper. The result indicates that the intumescent flame retardant is able to significantly reduce the peak heat release rate, total heat release (THR), peak smoke production rate, total smoke production (TSP) and mass loss rate. Compared with sole intumescent flame retardant, the combined application of intumescent flame retardant and Mg(OH)2 exhibits a superior flame retardance. The target for low smoke formation and high flame retardancy is realized through reducing TSP by 38% and THR by 10%.
