Abstract：The butyl rubber(IIR) reclaim was prepared with waste IIR bladder, unlinking agent and paraffin oil through synchronous rotor laboratory-scale mixer. Effects of filling factor(β), rotor speed, mixing time, amount of unlinking agent and paraffin oil on mechanical properties of IIR reclaim vulcanizates were investigated. The results showed that the mechanical properties of IIR reclaim vulcanizates could reach the best when β was 1, rotor speed was 100 r/min, mixing time was 15 min, unlinking agent was 3.5 phr and paraffin oil was 5 phr.
