| 摘 要： | 采用熔融共混法制备了一系列高岭土/天然橡胶(NR)复合材料,分析了改性高岭土(MK)、炭黑(CB)和白炭黑(PS)等不同类型填料对复合材料阻燃和热稳定性能的影响,并对高岭石的增强机理进行了探讨。研究结果表明:改性高岭土填充天然橡胶复合材料(MK/NR)的阻燃性能和热稳定性能得到了显著改善;填充量为50份时,MK/NR热稳定性能与CB/NR相当,优于PS/NR;MK/NR的阻燃性能与PS/NR相当,与CB/NR相比略有降低;填充70份高岭土时,高岭石颗粒在橡胶基体中形成了明显的卡房式空间分散结构。

| Abstract: | A series of nature rubber (NR) composites with modified kaolinite was prepared by melt bending. The effect of kaolin content on the flame retardancy and thermal stability of NR composites was investigated. The flame retardancy and thermal stability are obviously improved compared with the pure NR. The thermal stability of MK/NR is equivalent to CB/NR and better than PS/NR, and the flame retardancy of MK/NR equivalent to PS/NR and inferior to CB/NR when NR is filled with 50 fraction MK, PS and CB respectively. In the nature rubber matrix when it is filled by kaolin of 70 phr, the mature house-of-cards structure is edmanifest. |
