摘要
对比研究溶聚丁苯橡胶(SSBR)/稀土顺丁橡胶(NdBR)和SSBR/镍系顺丁橡胶(NiBR)并用胶在动态压缩条件下的形变、生热及粘弹性。结果表明:随着顺丁橡胶(BR)用量的增大,SSBR/BR并用胶的动态压缩形变减小,弹性改善,压缩疲劳温升升高,储能模量增大,损耗因子(tanδ)减小,损耗模量先减小后增大;与SSBR/NiBR并用胶相比,SSBR/NdBR并用胶具有更低的压缩疲劳温升、更小的压缩形变和tanδ,形变回复能力更优,生热更低。
The deformation,heat build up and viscoelasticity of SSBR/NdBR and SSBR/NiBR blends under dynamic compression were comparatively studied. The results showed that with the increasing of the additional level of BR,the dynamic compression deformation and tanδ of SSBR/BR blend decreased, the compression fatigue temperature rising,resilience and storage modulus increased,and the loss modulus first decreased and then increased. Compared with SSBR/NiBR blend,SSBR/NdBR blend had a lower compression fatigue temperature rising,compression deformation and tanδ,better deformation recovery ability and lower heat build up.
