Abstract
Abstract: Black sand (BS) was obtained from Rozita Beach in Egypt. It processed, for the first time, to reach the nanoscale range using Ball Mill technique. Different techniques were used to examine the BS nanoparticles (BS-NPs) including XRD and TEM. XRD analyses showed that BS-NPs composed mainly of Albite (Sodium Aluminium Silicate) up to 64% approximately. Silicon dioxide and zirconium oxide are also included in lower amounts 17.7 and 18.5 %, respectively. TEM examinations indicated that BS-NPs size ranged from 6 to 122 nm and the main diameter value was 31 nm. Novel polymeric nanocomposites were prepared by incorporating different concentrations of BS nanoparticles (BS-NPs) in Styrene butadiene rubber (SBR) matrix. The role of BS-NPs as filler was evaluated in terms of the rheometeric and mechanical properties of the SBR/BS nanocomposites. Compression technique was used to access the crosslink density of the nanocomposites. In parallel, SBR compounds containing carbon black and nanosilica, as fillers, were studied for comparison. Cure and mechanical measurements indicated that cure characteristics somehow approached those of NSPs and tensile poperties were founf to be close in value to those of SBR-NSPs canocomposites.
