研究了炭黑的变形历史和表面活性对炭黑填充橡胶粘弹性行为的影响。通过在γ=0.001∼0.4的应变区域内重复进行应变扫描，储能模量（G'）降低。 G' 的变化取决于最大应变 γ max。随着γ max 的增加，小应变区的G'下降。通过保持在给定温度下，样品显示出 G' 恢复。发现 G' 的恢复程度取决于温度和炭黑的表面活性。聚合物与填料之间的相互作用较弱的石墨化炭黑填充化合物的 G' 恢复程度比非石墨化化合物更高。发现石墨化炭黑的 G' 恢复行为是由于基质橡胶的粘度造成的。
Effects of deformation history and surface activity of carbon black on viscoelastic behavior of carbon black filled rubbers were investigated. Storage modulus (G') decreased by the repeated strain sweeps in the strain region of γ=0.001∼0.4. The change in G' depends on maximum strain, γ max. As the γ max increases, the G' in the small strain region drops. The samples showed recovery in G' by being kept at a given temperature. The degree of recovery in G' was found to depend on the temperature and the surface activity of carbon black. The degree of recovery in G' for graphitized carbon black filled compound which has weak interaction between polymer and filler, is higher compared to the nongraphitized one. The recovery behavior in G' for graphiitzed carbon black was found to be due to viscosity of rubber for matrix.
