New possibilities for cold plasma modification of furnace and acetylene carbon black

Some new possibilities for modification of furnace and acetylene carbon blacks by using cold plasma of oxygen, combination oxygen/ammonia and acrylic acid vapour are investigated. The surface treatment leads to appreciable change in the modulus at 100 and 300 % of elongation and in heat built-up, but does not reflect on the specific surface of the fillers and on the vulcanization parameters of the rubber compounds. A remarkable variation in the content of different elements on the fillers surface after modification was observed. The influence of the modified fillers on mechanical properties of non-polar and polar rubber vulcani-zates was studied.
