Abstract:
Mechanical activation (MA) of industrial carbon black (CB) by steel milling bodies with a diameter of 2 and 8 mm in air is performed. It was found that in the process of MA, the size of the CB aggregates decreases by an order of magnitude. The oxygen content on the carbon surface increases from 1.8 to 8.0 wt. % . Rubbers were prepared and vulcanized from methyl styrene-butadiene rubber (MSBR) industrial and mechanically activated CB; their dynamic-mechanical analysis was carried out and strength indicators were determined. The temperature dependences of storage modulus E’ and mechanical loss factor tan δ were obtained. It was found that the glass transition temperature Tg of rubbers with the introduction of MA CB decreases to -56 °C, compared with industrial CB: -52°C. This is due to the smaller size of the CB aggregates and the high oxygen content on the carbon surface. Strength tests have shown that for rubbers with mechanically activated CB, the maximum values of strength and elongation increase by more than 20% compared with the rubbers that contain industrial CB.
