Production of shungite concentrates - multifunctional fillers for elastomers

Abstract

The chemical composition of shungite from “Bolshevik” deposit was studied by energy-element analysis. It was established by X-ray diffraction method that in addition to the carbon component of shungite has a mineral part: hydromica type of illite, gidromuskovit, quartz, dolomite, chlorite, pyrite and siderite. Enrichment by flotation of shungite was carried out to concentrate of carbon and stabilize composition. The possibility of partial or complete replacement of technical carbon by new fillers based on shungite in rubber mixes was studied. The influence of shungite filler on the strength properties of rubber was studied. Strength properties of rubbers filled with shungite are above, compared to the properties of rubber filled with carbon black. Reinforcing effect of elastomers filled shungite is above compared reinforcing effect of the of elastomers filled standard technical carbon black.
