阻燃石蜡/聚丙烯定形相变材料的制备与性能研究

In this paper, paraffin wax as phase change material ， Polypropylene(PP) as support material，halloysite nanotube (HNTs) and intumescent flame retardant as flame retardants, the flame retardant form-stable phase change material was prepared through melt mixing method. In the case of certain total flame retardants content, through change the ratio of the two flame retardants, the synergistic effect between them of flame retardant form-stable phase change material was focus on. The results show that when the mass fraction of halloysite was 9%, the peak of heat release rate (PHRR) of flame retardant form-stable phase change material was reduced 48.2% compared to the flame retardant form-stable phase change material with simply intumescent flame retardant. In addition, the total heat release (THR),smoke release rate (SPR) and the release rate of carbon dioxide are significantly reduced.
