Comparison of adsorption properties of zinc oxide and shungite related to their influence as an activator of sulfur vulcanization

Abstract

Determination of the adsorption characteristics of zinc oxide and shungite with respect to benzene vapor adsorption was carried out by the BET method. The specific surface area was calculated, the curves of pore volumes distribution according to their size were constructed. The possibility of using shungite as an activator of sulfur vulcanization of butadiene-nitrile rubbers was shown.
