The influence of thermal ageing of natural rubber/styrene butadiene rubber vulcanizates on steady state and dynamic wear behaviour

The aim of this work is to explore the influence of thermal ageing on wear resistance of cured rubber which has been based on varied composition of Natural rubber/Styrene butadiene rubber compounds. The thermal ageing process has been performed in a heating chamber at the temperature 80 degrees C during 4 and 16 days, respectively. The wear behaviour has been analysed at steady state as well as at dynamic conditions. The qualitative parameter "weight loss" has been observed during the analysis based on both of methods. We demonstrate the relationship between rubber composition, based on varied ratio of rubber types, and varied wear processes in dependence on thermal ageing.government of the Czech Republic [CZ.1.05/2.1.00/03.0111]; Internal Grant Agency of the TBU [IGA/FT/2014/014]; Research and Development for Innovations Operational Programme
