Abstract

The influence of mechanical activation on porosity, structure (by absorption of dibutyl phthalate (DBP), the size of the agglomerates and the functional surface of the carbon black (CB) N375 was investigated. It was established that in the process of mechanical activation, the number of oxygencontaining groups on the surface CB increases to 0.34 meq/g and the size of the aggregates decreases from 300 to 3-5 microns. At the same time, the amount of absorption of DBP decreases. The rubber obtained on the basis of a mixture of SKMS-30 ARK rubber and mechanically activated CB is characterized by increased values of relative elongation under tension and a lower modulus of elasticity
