研究了炭黑、白炭黑和炭黑-白炭黑双相填料填充硫化胶在宽频、宽温范围内于低应变振幅下的动态性能,如剪切模量、损耗模量和损耗因子,其数据的变化范围宽,得到了羽毛状的假标准曲线,而不是单一的光滑的标准曲线,针对损耗因子,对这种结果做了特别说明,产生这种结果的原因可能是多方面的,其中填料-填料和填料-聚合物相互作用可能是最主要的原因。炭黑-白炭黑双相填料对硫化胶整个动态性能的影响与白炭黑类似:频率较低时,损耗因子较低;频率相对较高时,损耗因子较高。
The dynamic properties of double-phase filler-filled vulcanizates, including carbon black, white carbon and carbon black-silica, at low strain amplitudes, such as shear modulus, loss modulus and dissipation factor, The data has a wide range of variation, and the feather-like false standard curve is obtained instead of a single smooth standard curve. This result is specifically described according to the dissipation factor. The reasons for such a result may be manifold, Among them filler - filler and filler - polymer interaction may be the most important reason. The effect of carbon black-white carbon black bi-phase filler on the overall dynamic properties of the vulcanizates is similar to that of white carbon: at lower frequencies, the loss factor is lower; at higher frequencies, the loss factor is higher.
