| 摘 要： | 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。

| Abstract: | 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 troduced to it, and （FTIR）. It was found that the LOI values of composites increased when 1% metal compound was in- 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. |
