Desenvolvimento de elastômeros termoplásticos vulcanizados (TPV) a base de polipropileno com resíduo de pneu: I - Planejamento fatorial de experimentos

Abstract: pneu em misturas com termoplásticos tem ampla aplicação tecnológica e científica, porque são capazes de produzirem novos materiais com facilidade de processamento e boas propriedades elásticas. Entretanto, devido às diferenças estruturais e de viscosidade, a simples adição dos dois compostos não produz um novo material com sinergismo de propriedades [4][5][6] . É freqüente o uso de aditivos especiais a fim de compatibilizar e, consequentemente melhorar o desempenho da mistura. O que em muitos casos pode inviab… Show more

“…The ternary blends performance depends not only on the compatibility between the materials, but also on their structure, namely morphology and crystallinity. Several studies have already focused on the compatibility and morphology of these blends . However, the GTR effect on the TPE GTR blends crystallization kinetics still needs to be better understood and studied in more detail.…”

“…BMI can also act as a compatibilizer agent because it can react with free radicals of dissimilar polymer chains to give rise to copolymers; this increases the interfacial adhesion between immiscible polymers 32. This compatibilizing effect of BMI has been observed in several blend systems, including PP binary blends with waste tire dust,33, 34 nitrile rubber,11 natural rubber,35–37 ethylene octane copolymer,38 and EPDM;39 ternary blends containing PP and natural rubber/linear low‐density polyethylene,32 and EPDM/natural rubber;40 ethylene–vinyl acetate copolymer blended with epoxidized natural rubber;29 and poly(vinyl chloride)/epoxydized natural rubber (ENR) blends 41. In addition, the crosslinks formed by BMI are very stable with heating; this is a very interesting characteristic for the development of dynamic vulcanized systems 32, 42…”

“…Dentre os materiais poliméricos mais nocivos destacam-se aqueles que contem cargas de metais pesados, plastificantes e os pneus. Estes por serem reticulados e não reprocessáveis, são os mais indesejados, devido ao elevado tempo de degradação e a problemas de saúde pública (Cossa et al, 2009;Jang et al,1998;Pramanik et al 1995;De et al, 2004). Dessa maneira, a recuperação/aproveitamento de sólidos poliméricos vem se tornando cada vez mais importante, pois além dos interesses ambientais e econômicos, começam a surgir legislações cada vez mais rígidas no sentido de minimizar e/ou disciplinar o descarte desses resíduos sólidos (Spinacé e De Paoli, 2005;Coltro e Duarte, 2013;NBR 13230, 2008).…”
