| Abstract: |
| In order to balance the comprehensive practical performance of natural rubber(NR),NR vulcanizates were prepared by partially replacing the traditional filler carbon black(CB) with some graphene(Gr) using melt blending method. The influence of graphene addition on properties such as curing characteristics, physical mechanical properties and etc. were investigated by using various measurements. Experimental results showed that graphene degraded NR rubber’s processing safety, curing speed, crosslinking density and tear strength, but lifted its tensile strength, stress at fixed elongation, hardness and abrasion resistance. Graphene also entitled NR vulcanizates with better heat-aging resistance, tensile fatigue resistance and lower compression temperature rise as well as static compression permanent deformation rate. DMA results implied 3phr graphene resulted in NR rubber with lighter weight and balanced driving performances such as better wet-skid resistance and lower rolling resistance, which would be beneficial for safe and fuel-efficient tire products. |
