Abstract: |
Carbon black/natural rubber(NR),graphene/NR and carbon nanotubes/NR composites were prepared,and the effects of the thermal conductivities and interlayer contact resistances of the composites on microwave heating were studied by combining experimental and numerical simulation methods.The results show that the higher the thermal conductivities of carbon black,graphene and carbon nanotubes were,the higher the thermal conductivities of the composites were,and the lower the interlayer contact thermal resistances were.Increasing the filler amounts to increase the thermal conductivities of the composites and reduce the interlayer contact thermal resistances had certain limitations,and the applicability and economy of the composite formulation design needed to be considered.The thermal conductivities of the composites had little effect on the distribution patterns of high and low temperature regions and microwave heating efficiencies during the microwave heating process,however,the temperature distribution uniformities of the composites were significantly affected by the thermal conductivities.In order to ensure the uniformity of microwave heating vulcanization,the interlayer contact thermal resistances of multilayer composites could not be ignored. |
