Polymeric coatings based on LDPE and taurit - preparation, structure and mechanical properties

Abstract

The article describes a preparation method and performance behaviour of polymer composite systems with a matrix of LDPE and a reinforcing agent of taurit. Taurit (a species of shungite) is an inexpensive, well-available and environmentally friendly mineral, compatible with many polymers. The composites have been prepared via extrusion blending and their mechanical and protective properties have been studied. Performance of taurit-containing materials has been compared with properties of composites with other commonly used fillers (carbon black, talc, aluminium oxide, asbestos fibres, etc.) and taurit was proven to be the most efficient reinforcement in this series. The results indicate that the obtained composites can be used as coatings for pipelines to protect them from corrosion and mechanical damage.
