摘要
将季戊四醇磷酸酯三聚氰胺盐(PPM)和季戊四醇磷酸酯(PEPA)复配成一种新型膨胀型阻燃剂(IFR),并用于聚丙烯(PP)的阻燃。研究了该膨胀型阻燃剂的组成和用量对PP燃烧性能、力学性能和热性能等的影响,结果表明,由PPM和PEPA组成的IFR对PP具有优异的阻燃效果;PPM与PEPA质量比为3∶2,添加量为23%时,阻燃PP的氧指数为26.5%,阻燃级别达到UL94V0级;与PP相比,阻燃PP的弯曲强度提高,拉伸强度和冲击强度降低,熔点、起始分解温度降低,残炭量提高。
A novel intumescent flame retardant was prepared from pentaerythritol phosphate melamine salt （PPM） and pentaerythritol phosphate （PEPA）, and was used to flame retard polypropylene （PP）. The flammability performance, mechanical properties and thermal stability of flame-retarded PP were characterized by limiting oxygen index （LOI）, UL94 test, differential scanning calorimetry （DSC） and thermogravimetrie analysis （TG）. The results show that with the mass ratio of PPM to PEPA of 3：2 and a 23% loading of PPM and PEPA, PP/PPM/ PEPA blends meet UL94 V0 rating. Compared to PP, flexural strength of flame-retarded PP increases, tensile strength and impact strength decreases, decompition rate decreases, charring resides enhances.
