Abstract: In this paper, the effects of different plasticizing systems on the physical and mechanical
properties of NBR before and after aging were studied. The stress-strain curve of NBR after hot oil aging was
taken as the material parameter to investigate the effects of different plasticizing systems on the properties
of NBR during the buckling process; The experimental results of curing characteristics showed that when
DOP or DOA was used as plasticizer, the torque difference of vulcanizate was higher, while when liquid
nitrile or polysulfide rubber was used as plasticizer, the torque difference was relatively lower, and when
polysulfide rubber was used as plasticizer, the scorch time was shorter; The experimental results of physical
and mechanical properties showed that when liquid NBR or polysulfide rubber was used as plasticizer, the
retention rate of heat-resistant air aging property of NBR vulcanizate was relatively high, and the change rate
of mass and volume after heat-resistant oil aging was relatively low; The simulation results showed that when
DOP or DOA was used as plasticizer, the static stiffness, strain energy density and Mises stress at the joint were
higher, while when liquid nitrile or polysulfide rubber was used as plasticizer, the static stiffness, strain energy
density and Mises stress at the joint were lower.
Key words: plasticizing system; simulation calculation; material parameter; buckling
