SSBR/NdBR和SSBR/NiBR并用胶的动态压缩性能研究

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
