The structures and properties of reclaimed rubber (RR) modified with multi-block trans-1
4-poly(butadiene-co-isoprene) copolymer rubber (TBIR) were researched. The results showed that
the reclaimed rubber used in this experiment was consisted of 100 phr rubber and 58 phr filler. 100 phr TBIR and 58 phr carbon black (CB) were mixed for the TBIR master-batch preparation. 90~60 phr RR and 10~40 phr TBIR master-batch were mixed to prepare the RR/TBIR compounds. Compared with RR vulcanizates
such as improved tensile strength (33% to 83% higher)
modulus at 100% (31% to 75% higher)
tear strength (39% to 76%higher)
shore A hardness (3% to 11% higher)
rebound (30% to 65% higher)
abrasion resistance (11% to 25%higher)
tensile fatigue resistance (0.5 to 2.1 times)
flex fatigue crack initiation resistance (1.0 to 7. 3 times)
hot-air ageing resistance (11% to 59% higher) and ozone ageing resistance (5% to 27% higher)
and decreased rolling resistance(20% to 42% lower). The improved polymer networks
filler-polymer interaction and filler distribution of RR was obtained through the simple blending of RR and TBIR. A high performance modification strategy for RR with TBIR is proposed.
