Influence of carbon black from pyrolysis of waste tires in a polymer matrix Einfluss von Ruß aus der Pyrolyse von Altreifen in einer Polymermatrix

Tires are one of the most important products in world transportation industry. The number of cars increases on the road and thus the amount of waste tires. Pyrolysis is one of the possibilities of recycling used waste tires. This work is focus on the characterization and application product (carbon black) from pyrolysis of waste tires in the polymer matrix. Carbon black from pyrolysis of waste tires is used as a filler in the polymer matrix in order to replace by conventional carbon black (N339 and N660). Thermal analysis, infrared spectrometry and Energy-dispersive x-ray spectroscopy analysis are used to determine the changes in the properties of waste tires pyrolysis carbon black compared to conventional carbon blacks. A scanning electron microscope is used to characterize the shape of the carbon black. After the application of fillers in the polymer matrix, the cure characteristics, reinforcing of the mixture and the mechanical properties are determined. Fraction adjustment of the carbon black from pyrolysis of waste tire shows a positive influence on the properties.
