| 摘 要： | 通过毒性实验分析了废轮胎橡胶(GTR)主要组分对酿酒酵母（S.cerevisiae）R1生长的影响，并用乙醇解毒，减少其对S.cerevisiae R1的抑制作用。经132h再生后，30份再生GTR填充到丁苯橡胶(SBR)基体中的力学性能均好于未经S.cerevisiae R1再生的硫化橡胶，其溶胀值增加4.6%，交联密度下降，撕裂强度提高了26%。再生GTR与SBR界面接触良好，XPS测试显示C元素基本不变，S元素质量分数降低了23.86%，具有显著的脱硫效果。

| Abstract: | The yeast species S.cerevisiae R1 has the capability to recycle waste rubber.However the many toxic additives in rubber have a significant inhibiting effect on the growth of S.cerevisiae R1,as shown by our toxicity tests.Ethanol leaching of the rubber material can remove some of these toxic additives,reducing the adverse impact on the growth of the microorganism.After 132 hours of regeneration,a remarkable decrease in crosslink density,increase in swelling ratio(4.6%),and better physical properties were obs... |
