摘要
通过对天然橡胶(NR)、顺丁橡胶(BR)、丁苯橡胶(SBR)、溴化丁基橡胶(BIIR)及NR/BR/SBR/BIIR并用胶进行热重-微分热重分析和热重-差示扫描量热分析,探讨废旧橡胶的裂解机理。结果表明:NR和BIIR裂解反应过程相似,均只有1个明显的质量损失过程,1个质量损失速率峰值;BR与SBR裂解反应过程相似,均分为2个阶段,第1阶段质量损失较小,第2阶段质量损失比第1阶段明显增大;NR/BR/SBR/BIIR并用胶的裂解反应过程与BR相似,裂解反应特征温度相近。
The cracking mechanism of waste rubber was studied by thermogravimetric-derivative thermogravimetric analysis and thermogravimetric-differential scanning analysis of NR,BR,SBR,BIIR and NR/BR/SBR/BIIR blends.The results showed that the cracking reaction process of NR and BIIR was similar,which had only one obvious mass loss process and one peak mass loss rate.The cracking reaction process of BR and SBR was similar,which was divided into two stages.The first stage had a small mass loss,and the second stage had a larger mass loss.The cracking reaction process of NR/BR/SBR/BIIR blends was similar to that of BR,and the characteristic temperature of the cracking reaction was close.
