Exploration and Mining
Application of rubber at higher temperatures requires sufficient heat resistance. The experimental research was carried out with the rubber intended for use at higher operating temperatures as gaskets for caps in mining. The intakes during the operation of the rubber gasket are accompanied with physical as well as chemical changes that lead to thermal degradation of the material. The mechanical properties (tensile strength, elongation, Shore hardness, and abrasion resistance) of the examined type of rubber were determined for unused, i.e., new rubber. The rubber samples were subjected to accelerated thermal ageing at 180 °C for 3 days. After ageing, the mechanical properties of the thermally degraded rubber were determined in order to establish its heat resistance. Strength and elongation decreased by ageing, but the Shore hardness increased. The percentage of change in the strength was -1.2 %; -8.9 % for elongation; and the absolute change in the Shore hardness was 1.7, representing a 2.3 % increase. Thus, the heat resistance of the tested rubber was sufficient, as confirmed by the measured mechanical properties (strength, elongation, and Shore hardness).
