| Abstract: |
| 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. |
