Ground tire rubber (GTR) was reclaimed and modified with 10 phr of ethylene-vinyl acetate copolymer via low-temperature extrusion process. Processing, physico-mechanical properties, volatile organic compounds emission, and recycling possibility were investigated. In order to better understand the impact of used modifiers, their efficiency was compared with trans-polyoctenamer, which is an additive that is commercially dedicated to waste rubber recycling. The results showed that a relatively small amount of ethylene-vinyl acetate copolymer improves the mechanical properties of modified reclaimed GTR and also allows further recycling by multiple processing without the deterioration of performance after three cycles.
通过低温挤出工艺，用10份乙烯-醋酸乙烯酯共聚物对废轮胎橡胶（GTR）进行再生和改性。研究了其加工性能、物理机械性能、挥发性有机化合物排放以及回收可能性。为了更好地理解所用改性剂的影响，将它们的效率与反式聚辛烯进行了比较，反式聚辛烯是一种专门用于废橡胶回收的商业添加剂。结果表明，相对少量的乙烯-醋酸乙烯酯共聚物可改善改性再生GTR的机械性能，并且还能通过多次加工实现进一步回收，经过三个循环后性能不会恶化。
