| 摘 要： | 以硅烷偶联剂、钛酸酯偶联剂和磷酸酯偶联剂对天然纤维水镁石(FB)阻燃剂进行表面改性.将未改性与改性的FB分别填充聚丙烯(PP),研究了未改性与改性的FB及填充量对PP的力学性能和阻燃性能的影响,结果表明:未改性与改性的FB填充量在37.4%以下时,磷酸酯偶联剂改性FB填充PP的熔体流动速率和钛酸酯偶联剂改性FB填充PP的断裂伸长率下降最小;未改性与改性的FB填充量在28.5%时,硅烷偶联剂改性FB填充PP的抗拉强度增强最多;FB的填充量为41.2%时,有明显的阻燃效果,PP的氧指数O_Ⅰ]为28.5%,当改性FB以此填充量加入PP时,酸酯偶联剂改性FB填充PP的力学性能较好,PP的拉伸强度和缺口冲击强度分别在21.10～22.51MPa和4.25～4.98MPa之间.最后,对纤维水镁石的阻燃机理进行了研究.

| Abstract: | The silane coupling agent, titanate coupling agent and organic phosphate coupling agent as surface modifiers were used to modify the natural fibrous brucite(FB) flame-retardant. The unmodified FB and modified FB were introduced into polypropylene to form composite plastic. The influences of unmodified FB and modified FB and flame-retardant content on the mechanical and flame-retardant properties of PP were studied. The results showed the melt flow rate of PP filled with FB modified by silane coupling agent ... |
