| 摘 要： | 用氧指数(LOI)测定、力学性能测定、热失重分析(TGA)方法研究了TBC对三元乙丙橡胶(EPDM)／聚丙烯(PP)阻燃耐热性和力学性能的影响。结果表明，使用TBC，EPDM／PP的阻燃效果较好，TBC主要发挥气相阻燃作用。5％TBC的加入增加了共混体系的拉仲强度和断裂伸长率；但随着TBC用量的继续增加，拉伸强度和断裂伸长率都有所降低。加入TBC后，共混物的起始失重温度明显降低，但对EPDM／PP的热稳定性没有多大的影响，不影响EPDM／PP的正常使用。

| Abstract: | The effect of TBC on EPDM/PP was studied by the mechanical, flame-retardant properties determination and thermo-gravimetric analysis. The results showed that TBC had some flame retardation on EPDM/PP. TBC could play in gas phase flame-retarding role. The addition of TBC in EPDM/PP increased the tensile strength and elongation at break of the material, but the tensile strength and elongation at break were decreased with increasing amounts of TBC. The add-on of TBC could lower the initial decomposition temperature of EPDM/PP, but which doesn't affect its thermal stability and application. |
