Abstract: |
The effect of liquid isoprene rubber(LIR) on properties of NR/BR compound,physical properties and thermal air aging property of its vulcanizate was investigated and compared to that of aromatic oil.The results showed that the plasticating effect of LIR on NR/BR blend was lower than that of aromatic oil;the comprehensive physical properties and thermal air aging property of NR/BR vulcanizate with LIR were better than those with aromatic oil;and LIR was co-crosslinked with NR and BR during vulcanization. |
