The abrasion resistance and tensile strength of the adhesive are closely related. The nanometer structure of carbon black surface makes the tensile failure of the adhesive increase with the tensile strength, so the abrasion loss is reduced. The distance between the two aggregates or the size and the mesh size of the mesh has a certain correlation with the strength of the mesh, which directly reflects the abrasion resistance of the material. In the study of filler network, it was found that the abrasion resistance of gelatine was not related to the variety of black carbon. Only when the distance between the groups was 20 nm, the abrasion resistance of glue was the best [3, 4]. This can be interpreted as all carbon black have nanostructures, in 5 ~ 8 nm carbon black surface low motility rubber layer, only when the distance between the aggregate of 20 nm, aggregation of actual moving between rubber layer only 4 ~ 10 nm. Because this free rubber layer on the deformation occurs when external force can not only resolve the role of external force, will force the mechanical energy into heat energy, and can make the rubber elastomer for strain without destruction, make rubber elastomers has the best reinforcing effect. We need further research on this. In addition, under harsh conditions, only carbon black with a rich nano-structure can provide sufficient anti-tear energy for the adhesive. In conclusion, the nanostructure of carbon black is very important and complex for the abrasion resistance of rubber materials.
