| Popis: | The paper deals with the proposal and preparation of the suitable rubber compounds in which materials are based on natural bentonite. It is important to point out that the mentioned materials were used in the function of the fillers. In relation to the prepared rubber compounds, vulcanization and rheological properties were determined (minimum torque - M L , maximum torque - M H , processing safety - t S , optimum vulcanization time - t C(90) , rate coefficient of vulcanization - R v ). Prepared vulcanizates were evaluated from the aspect of physical and mechanical properties (tensile strength, elongation, hardness) and heat aging of vulcanizates was also evaluated. These characteristic features were compared with those which are typical for standard rubber compounds used in the rubber industry while standard filler is carbon black of N339 type. |
