Abstract
ABSTRACT The use of crumb rubber is one form of recycling scrap tires that can aid in addressing the environmental concerns of tire disposal. In the present investigation, reinforced wood–plastic composites (WPCs) were manufactured incorporating crumb rubber. The bulk density of crumb rubber-reinforced WPC was found to be 19% higher than the baseline materials. This indicated that crumb rubber assisted in the consolidation process. Both baseline and crumb rubber-reinforced WPC materials were mechanically characterized according to ASTM D 1037. Compression modulus of crumb rubber-reinforced WPC showed an increase of 200% as compared to baseline WPC. Cone calorimetry demonstrated that the peak heat release rate, the maximum average rate of heat emission (MARHE), effective heat of combustion, and fuel load of crumb rubber-reinforced WPC were lower than the baseline WPC. Nonetheless, it was observed that the amount of CO and CO2 produced were more in the case of crumb rubber-reinforced WPC.
橡胶屑的使用是回收废旧轮胎的一种形式，可以帮助解决轮胎处置的环境问题。在本研究中，以橡胶屑为原料制备了增强木塑复合材料。颗粒橡胶增强木塑的容重比基准材料高出19%。这表明橡胶屑有助于固结过程。基线和颗粒橡胶增强木塑材料均根据ASTM D 1037进行机械表征。颗粒橡胶增强木塑复合材料的压缩模量比基线木塑复合材料提高了200%。锥形量热法测定结果表明，木质复合材料的峰值放热率、最大平均放热率(MARHE)、有效燃烧热和燃料负荷均低于基准木质复合材料。尽管如此，据观察，CO和CO2的量产生更多的情况下，碎橡胶增强木复合材料。
