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.
