Instead of conventional carbon black, an alternative carbon filler (ACB) obtained in the pyrolysis process from tire waste was used for rubber compounds. The fillers were characterized using FTIR and TGA methods. The mechanical properties of the obtained rubber compounds and the influence of the fillers used on the vulcanization process, as well as the Payne effect, were examined. The results confirm the possibility of replacing conventional carbon black with an alternative carbon filler in rubber compounds.

Do mieszanek gumowych zamiast konwencjonalnej sadzy zastosowano alternatywny napełniacz węglowy (ACB) otrzymany w procesie pirolizy z odpadów opon. Napełniacze scharakteryzowano za pomocą FTIR i TGA. Zbadano właściwości mechaniczne otrzymanych mieszanek gumowych oraz wpływ stosowanych napełniaczy na przebieg procesu wulkanizacji, a także na efekt Payne’a. Wyniki potwierdzają możliwość zastąpienia konwencjonalnej sadzy alternatywnym napełniaczem węglowym w mieszankach gumowych.

The targeted modification of the material composition is a common procedure used to improve the parameters of the final products. This paper deals with the targeted modification of polymer systems composition using two various types of alternative fillers. The first type of alternative filler (SVD) has been obtained from energetics where it arises as a by-product of flue gas desulfurization. The second alternative filler used (KAL) is based on waste from glass production. The elastomeric systems designed for the production of car tires and solid wheels for transport systems were used in the role of modified polymer systems. Alternative fillers (SVD, KAL) have been applied as a substitution of commonly used fillers (carbon black, silica). The filler – elastomeric matrix interaction, rheology, cure characteristics, as well as hardness and rebound resilience of vulcanizates, which are important parameters for their industrial application, have been studied in the new prepared polymeric systems. The main output of the work is a new formulation of an elastomeric system for industrial applications with high rebound resilience and low rolling resistance, which is the subject of the international patent. The modification of composition using raw material substitution can also bring significant environmental and economic effects.
