Kinetics of phase-selective distribution of hybrid filler systems in heterogenous rubber blends and their synergistic effects on the physical properties

该项目的目的是开发一种定量描述增强混杂填充体系在橡胶共混物中的选择性润湿和分布动力学的方法，以及由其通过交联制得的相应的异相弹性体。因此，橡胶配方、混炼工艺、形态发展和由此产生的性能之间的关系应该基于定义良好的模型系统来表征和解释。因此，橡胶特定工艺混炼过程中的在线表征方法将与分析方法相结合。借助于已有的基本知识，橡胶混炼过程中填料组分的特定相位化是弹性体物理机械性能的一个决定性因素，这是可以预先描述的。开发的方法将使用材料系统进行实验验证，这些材料系统的配方从面向应用的角度进行扩展。

The aim of the project is the development of a method for quantitative description of the selective wetting and distribution kinetics of reinforcing hybrid-filler-systems in rubber blends and the corresponding heterophasic elastomers made therefrom by cross-linking. Thus the relationships between rubber compound formulation, mixing technology, morphology development and resulting properties shall be characterized and explained based on well-defined model systems. Therefore, in-line characterization methods during the rubber specific technological mixing process will be combined with analytical methods. By means of the fundamental knowledge achieved, the phase-specific localization of the filler components during rubber compounding, which is a decisive factor for the physico-mechanical properties of the elastomers, shall be describable apriori. The developed method will be experimentally verified using material systems whose formulations are expanded from application-oriented point of view.
