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.

Abstract

This article presents a procedure of the activation of halloysite and a method of the synthesis of nucleus-sheath type filler. The effects of the nanoadditives obtained on the thermal properties, flammabilities and fire hazards of peroxide and sulfur vulcanizates of NBR and SBR rubbers, are discussed. Based on the test results obtained by derivatography, oxygen index, FAA micro-calorimeter and cone calorimeter, the thermal stability, flammability, and fire hazard of the nanocomposites investigated were determined. The results obtained were interpreted from the point of view of the chemical structure of the diene elastomers investigated, their spatial network structure, and the method of halloysite modification.
