【摘要】 采用常规的双辊混炼法制备出了剥离型的天然橡胶/蒙脱土纳米复合材料。利用透射电子显微镜观察复合材料的亚微观形态,测试了材料的物理性能,研究了材料的应力-应变变化曲线,表征了材料的加工流动性变化,测试结果表明制备出了剥离型纳米复合材料,低填充量(小于3份)时力学性能大大提高,应力-应变明显变化,加工流动性略有不同。更多还原

【Abstract】 Natural rubber(NR)/organoclay exfoliated nanocomposites was prepared by direct two-roll compounding.The nanocomposites substructure was characterized by transmission electron microscopy(TEM),and its mechanical properties and stress-strain curve was studied,and the processability of nanocomposites was characterized by Mooney viscosity testing.The results showed that the organoclay was exfoliated in the NR matrix,and as the filler loading below 3 phr,the mechanical properties of the product improved greatly,and the stress-strain curve changed markedly,with the processability changed a little.更多还原
