摘要
采用油泥为再生剂对废硫化橡胶进行再生,考察了再生工艺和再生体积配方对再生效果的影响。实验结果表明:在脱硫温度为200℃,反应压力为2 MPa,油泥与废胶粉用量比小于10时,反应6 h,可以使硫化胶再生,得到的再生胶的硫化性能、物理机械性能和生物毒性基本达标。
The regeneration process and the influence of formulation on regeneration of scrap rubber powder were studied in the present paper. The experimental results showed that the Cur characteristics, the mechanical properties and the biological toxicity of the reclaimed rubber were basically qualified when the rubber powder was infiltrated by oily sludge at 200℃ for 6 hours and the volume ratio of oily sludge and rubber powder was lower than 10. It implies that the reclamation scrap rubber can be realized using oily sludge as hazardfree regenerant.
