The present invention discloses a wide-temperature-range highly insulating rubber composite material for extreme environments and the prepared wide-temperature-range highly insulating rubber composite material, which relates to the technical field of rubber composite materials and aims to solve the technical problem of heat accumulation caused by poor thermal conductivity of fillers in silicone rubber-based composite materials. In the present invention, surface-hydroxylated modified boron nitride nanosheets are used to replace traditional fumed silica. The boron nitride nanosheets themselves are two-dimensional nanomaterials that combine excellent insulation, extremely high thermal conductivity, and good mechanical strength, thus solving the problem of heat accumulation caused by poor thermal conductivity of fillers in silicone rubber-based composite materials.
