The Modification of Surface of Dispersed Fillers for Their Application in Polymer-Elastomer Composites

Structural studies of mechanoactivation-modified dispersed fillers (natural zeolite and magnesium spinel) and polymer-elastomer composites on their basis are performed. It is shown that mechanoactivation in an Aktivator-2S planetary mill (80.3 g, 900 rpm) allows halving the treatment duration and providing the greatest changes in the structure of dispersed fillers as compared to Pulverisette-5 (22 g, 400 rpm). The predominant localization of particles of mechanically activated fillers at the phase interface of the polymer mixture (BNKS-18/UHMPE) is found. This results in intensification of their interaction at the interface and, hence, improvement in obtaining polymer-elastomer materials with an improved set of physicomechanical properties.
