Thermal stability and flammability of butadiene–styrene rubber nanocomposites

Abstract

This paper presents the effect of halloysite intercalated with a base or modified montmorillonite on the thermal properties and flammability of peroxide and sulfur vulcanizates of styrene–butadiene rubber (SBR). Based on the test results obtained by means of thermal analyses (DTA, TG, DTG, and DSC), oxygen index and microcalorimeter (FAA) it has been found that the thermal stability and flammability of the nanocomposites investigated depend on the spatial network structure as well as the content and type of nanoadditive in the vulcanizate obtained. The nanofillers used considerably reduce the flammability and fire hazard of the cross-linked SBR.
