| 摘 要： | 烧结法赤泥分别经硬脂酸、铝酸酯偶联剂、硅烷偶联剂和十二烷基苯磺酸钠湿法球磨改性后，与丁苯橡胶（SBR）进行熔融共混，制得改性赤泥/SBR复合材料，然后对改性赤泥和赤泥/SBR复合材料的表面性质、微观结构和力学性能进行表征测试。结果表明：球磨改性后的赤泥粒度减小，表面官能团含量发生变化。经硅烷偶联剂改性的赤泥，Si—O—C和Si—O—Si官能团含量增加，触角明显增大；改性赤泥在丁苯胶复合材料中分散性和相容性增加，硅烷偶联剂改性后的赤泥填充橡胶复合材料的力学性能显著增加，拉伸和撕裂强度分别由纯胶的1.6MPa和8.8 kN/m2增加到9.8MPa和21.6kN/m2，改性赤泥补强效果较为明显。

| Abstract: | SBR composites filled with sintered red mud separately modified by stearic acid, aluminate coupling agent，silane coupling agent and sodium dodecyl benzene sulfonate modifier in a ball mill were prepared by melt blending. Surface nature, microstructure and mechanical properties of the modified red mud and red mud /SBR composites were characterized. Results showed that the particle size of the red mud reduced and surface functional groups changed after ball milling modification. The functional groups of Si—O—C, Si—O—Si and the antennae increased significantly in red mud modified by silane coupling agent. The modified red mud showed good dispersibility and compatibility, and the mechanical properties of the red mud-filled rubber composites modified by the silane coupling agent increased significantly. The tensile and tear strengths were increased from 1.6MPa and 8.8kN/m of pure rubber to 9.8MPa and 21.6kN/m, respectively. |
