| 摘 要： | 自制一种有机改性蒙脱土(OMMT),采用双辊共混法与三元乙丙橡胶复合,得到了具有高强度、低硬度等超常力学性能的乙丙橡胶/有机蒙脱土纳米复合材料。透射电镜观察表明,制备出了半剥离型纳米复合材料,力学性能测试显示,在低填充量(15份以下)时,纳米复合材料的各项力学性能远超过同含量下高耐磨碳黑体系的。在填充量为10份时,有机土填充体系的断裂强度为15.85 MPa,是碳黑填充体系(6.57 MPa)的2.4倍,是纯橡胶体系(2.05 MPa)的7倍多;撕裂强度也高于碳黑体系和纯胶体系的;而此时纳米复合材料的邵A硬度仅为58.5,比相同强度下碳黑补强体系的低近10。

| Abstract: | Ethylene-propylene-diene(EPDM)/OMMT nanocomposites were prepared with a new type OMMT through two-roll blending.The results of transmission electron microscopy(TEM) observation showed that the particles of OMMT were interca-lated or exfoliated in the EPDM matrix.The mechanical properties testing results indicated that as the filler loading below 15 phr the mechanical properties of OMMT system were higher than those of carbon black system.The tensile strength of the EPDM/OMMT nanocomposites at the filler content of 10 phr reached 15.85MPa,that is the 2.4 times of carbon black system and more 7 times of neat EPDM system respectively.The tear strength of OMMT was higher than that of carbon black,simul-taneously the shore A hardness of the OMMT system is 10 lower than that of carbon black system at the same strength. |
