Putman ABSTRACT =========== Rubber mixing has traditionally been optimized by testing, and relating physical properties to mixing conditions. A larger number of studies have focused on carbon black dispersion, and its effects on rubber properties, through the use of various rapid techniques including reflected light with image processing. Recent technology has allowed for the measurement of filler dispersion, providing direct feedback regarding the incorporation and the disagglomeration of carbon black. These methods were insufficient for testing silica dispersion, due to limitations in resolution and overexposure on light-colored surfaces. Measurement of silica dispersion has grown in relevance in recent years, while analytical techniques to quantify dispersion remained a challenge. Methods for analyzing silica dispersion directly have been time-consuming and required a unique expertise in complex microscopy. The required use of the silane coupling agent further complicates the relationship between dispersion and physical properties due to its effects on processability and cure. A new improved method for measuring dispersion with a resolution of 1.5 microns is described. This study investigates the effect of mixing untreated silica filled compounds as well as silane modified compounds. Filler dispersion is measured by this method and the results are compared to physical properties. The new method provides a rapid way to accurately measure dispersion. |
