ABSTRACT
Rubber rollers play an important role in the production of everyday objects as well as industry articles. They have to withstand a wide range of thermo-mechanical and chemicals loads, depending on their field of application (e.g. printing, pressing, transportation). Despite its great importance, the microscopic thermo-mechanical aging mechanism of filled elastomer compounds typically used for rubber rollers remains poorly understood. Especially the complex interplay of polymerand filler components is difficult to observe experimentally. In this work we use the Dynamic Flocculation Model (DFM) to derive microscopic network parameters from macroscopic mechanical measurements. The DFM was firstly set up by Klüppel (2003) and further developed Lorenz et al. (2011) to describe the stress-strain behavior of filled elastomer compounds over the whole range of amplitudes. All fit parameters are based on physical assumptions and allow a deep insight into the materials microstructure.
