我们研究了填料对橡胶-塑料二元和三元共混物的力学性能、动态力学性能和老化性能的影响，所述橡胶-塑料二元和三元共混物来自丙烯酸酯橡胶、氟橡胶和多官能丙烯酸酯。添加填料，如炭黑和二氧化硅，改变了应力-变形行为的性质，对于给定的应变具有更高的应力水平。拉伸强度和撕裂强度随着填料的加入和载荷的增加而增加，但断裂伸长率下降，拉伸永久变形不受影响。由于炭黑的热抗氧化性，炭黑填充共混物的老化性能更好。随着填料的加入，二元和三元共混物在甲乙酮中的耐溶胀性增加。从动态力学热分析，我们得出结论，填料改变了在玻璃化转变温度的阻尼峰的高度和半宽度。在较高的温度下，损耗角正切值几乎没有变化。填料的较高负载增加了在所有测量温度下的储能模量。(C)2003 Wiley Periodicals，Inc.
We studied the effects of fillers on the mechanical, dynamic mechanical, and aging properties of rubber-plastic binary and ternary blends derived from acrylic rubber, fluorocarbon rubber, and multifunctional acrylates. The addition of fillers, such as carbon black and silica, changed the nature of the stress-deformation behavior with a higher stress level for a given strain. The tensile and tear strengths increased with the addition of the fillers and with loading, but the elongation at break decreased, and the tension set remained unaffected. The aging properties of carbon-black-filled blends were better because of the thermal antioxidant nature of carbon black. The swelling resistance of the binary and the ternary blends in methyl ethyl ketone increased with the incorporation of fillers. From dynamic mechanical thermal analysis, we concluded that the filler altered the height and half-width of the damping peak at the glass-transition temperatures. There was little change in the loss tangent values at higher temperatures. A higher loading of the filler increased the storage modulus at all of the temperatures measured.
