中文摘要:
      采用同向双螺杆挤出机实现废胶粉高度脱硫解聚,制备了液体再生胶。通过凝胶液相色谱、傅里叶红外光谱发现和再交联测试发现其具有独特的特点：溶胶含量高,黏度低,具有可再交联的特性。通过将液体再生胶和环保芳烃油按试验配方分别与生胶制备混炼胶,从混炼胶的门尼粘度、丙酮抽出物、硫化特性和硫化胶的力学性能进行考察,发现液体再生胶具有一定的增塑效果,与生胶相容性较好,混炼胶丙酮抽出物少,难喷霜；和环保芳烃油相比,液体再生胶在硫化过程中参与交联反应,含液体再生胶的硫化胶具有更好的拉伸强度、硬度和定伸应力,表明制备的液体再生胶起到了反应型高分子增塑剂的作用。
英文摘要:
      Liquid reclaimed rubber（LRR） was prepared by co-rotating twin screw extruder，and used as reactive polymer plasticizer in natural rubber（NR） compounds to study its application effect. The results showed that the LRR had relatively high sol content，small viscosity and re-vulcanized ability. The LRR had certain plasticizing effect and good compatibility with NR. The content of acetone extract of the compound was low and there was basically no blooming problem. Compared with the vulcanizate environment-friendly aromatic oil，the vulcanizates with LRR had higher hardness，modulus and tensile strength because LRR participated in the crosslinking reaction in the vulcanization process，indicating that LRR played the role of reactive polymer plasticizer.
