Abstract

Knowledge about the influence of rubber – filler interactions on the wet skid behavior of tire treads is insufficient, in order to quickly develop new compounds with improved wet skid performance. The rubber compound used for a tire tread is in fact a composite material of which the dynamic properties can be adjusted over a relatively broad range by modification of the polymer – filler interaction. In case of silica reinforced rubber, due to silanol-groups present on its surface, it posesses unique opportunities to control the chemistry of the polymer-filler interface. Control over the polymer-filler interface is realized by chemical modification of the silica surface. In order to achieve this modification, different silane coupling agents must be applied. By changing the type of coupling agent, different molecular structures can be obtained which lead to changes in macroscopic material properties including wet skid resistance. A better understanding of one of the influencing factors, the polymer-filler interaction and it’s influence on wet skid resistance helps to answer the central question: Which type of polymer-filler bonds govern wet skid phenomena? In this paper, the effect of physical and chemical polymer-filler bonds on the macroscopic dynamic properties of a silica reinforced tire tread compound, including wet skid resistance are discussed. In order to obtain different bond types, various silanes are used. The influence of the different silane types on the other properties of the material will also be discussed.
