Abstract
The present paper deals with a preparation of new elastomeric compounds containing two kinds of alternative additives based on wastes from glass production and energetics. Named alternative fillers were mixed into rubber compounds asa replacement of commonly used fillers – carbon black and silica. Rheological properties, vulcanization 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 elastomeric systems. The resulting vulcanizates containing alternative fillers exhibit improved properties, in particular low rolling resistance and high rebound resilience, while maintaining optimal hardness values. Used raw material substitution can also bring significant environmental and economic effects.
Highlights
Most industrial products carry with them the creation of a byproduct or waste from production
In the results and discussion there are summarized the results of curing properties determination of prepared rubber blends and measurements of hardness and rebound resilience of final elastomeric vulcanizates containing the alternative fillers
Alternative filler from glass production caused higher stiffening effect compared to alternative filler ENERGO
Summary
Most industrial products carry with them the creation of a byproduct or waste from production. Waste disposal is economically demanding, and businesses try to reuse it, whether in primary production or in sales as a secondary raw material for other industries. As a secondary raw material, waste can become an alternative filler in the rubber industry. In addition to improving the properties of the resulting elastomer in the case of the application of alternative waste-based fillers, the low cost of the resulting product and the greening of production are of great benefit. The first alternative filler (GWI) used in present experiments comes from the weighing process of raw materials in glass production, where creates the waste in a sludge form. The other type (ENERGO) arises as a byproduct in the flue gas desulphurization process in energetics
