以多聚磷酸铵（APP）与新型三嗪类成炭剂（CNCA-DA）复配成新型膨胀型阻燃剂（IFR），将其应用在乙丙弹性体中（EP），并采用氧指数测定仪（LOI）、热重分析仪（TGA）和红外光谱（FTIR）研究了碳酸镍（NC）和硼酸锌（ZB）与EP/IFR体系阻燃性能的影响。结果表明，用1%的金属化合物替代1%的IFR后，复合材料的氧指数值都有一定程度的改善，其中NC的效果较好，达到27.6%；TGA分析结果表明，金属化合物都能促使复合材料保留更多的残炭；FTIR分析表明，金属化合物能促使残炭中形成了聚芳烃和P-O-C、P-O-P的交联结构。%Novel intumescent flame retardant (IFR) was composed by ammonium polyphosphate (APP) and novel trizine charring agent (CNCA-DA), and the synergistic effect between nickel carbonate (NC), zinc borate (ZB) and EP/IFR sys-tem was investigated by means of limited oxygen index (LOI), thermogravimetric analysis (TGA) and fourier transform in-frared spectroscopy (FTIR). It was found that the LOI values of composites increased when 1%metal compound was in-troduced to it, and NC had a better synergistic effect. The TGA results showed that the composites decomposed early at high temperature when 1%metal compound was added, and it retained more char residue when metallic compound was incorporated into it. The FTIR results revealed that polyaromatic hydrocarbon, P-O-C and P-O-P connected structures were formed.
