Aqueous Dispersions of Latex Compounding Ingredients by Wet Ball Milling: Effect of Ball Size and Milling Time on Dispersion Quality

摘要

Abstract Preparation of nanomaterials, their functionalization, evaluation and usage for potential applications are the main objectives in materials science research. Preparation of ultra-fine/nano-sized particle dispersions and their stabilization is a great challenge among researchers where the high surface area and energy impedes the effective usage of nanomaterials. This study presents the effect of ball milling on size and stability of aqueous dispersions of latex compounding ingredients such as china clay, zinc diethyldithiocarbamate, zinc 2-mercapto benzothiazole and butylated reaction product of p-cresol and dicyclopentadiene (wingstay L). The particle size and stability have been assessed through dynamic light scattering technique and sedimentation test. By using lower sized balls for milling, the particle size of latex compounding ingredients can be reduced to a great extent.
