Postupci recikliranja otpadnih gumenih proizvoda za dobijanje elastomernih hibridnih materijala

Preparation of elastomeric materials based on recycled elastomer powder is huge ecological tasc.The goal of this applicative work was to synthesize hybrid materials based on sulfur cured ternary blends of polyisoprene rubber, polybutadiene rubber, and styrene-butadiene rubber filled with carbon black nano-particles and waste rubber powder (REP). Properties and ageing of prepared materials were assessed as a function of REP content. The stress-strain experiments were measured before and after the aging. It was assessed that the tensile strength of obtained materials decreased as the content of recycled rubber increased.Dobijanje sirovina na osnovu otpadnih gumenih proizvoda predstavlja voma značajan ekološki zadatak. Cilj ovog aplikativnog rada je bio da se sintetišu hibridni elastomerni materijali na osnovu sumporom umrežene ter-blende prirodnog kaučuka, polibutadienskog kaučuka i stiren-butadienskog kaučuka, aktivnog nano-punila i mlevene otpadne gume (REP). Određena su mehanička svojstva dobijenih materijala pre i posle starenja u funkciji sadržaja recikliranog gumenog praha. Ustanovljeno je da se prekidna čvrstoća sintetisanih hibridnih materijala smanjuje sa porastom sadržaja recikliranog elastomernog praha
