Low-dimensional carbon material reinforced carbon graphite material and preparation method thereof
The invention relates to a low-dimensional carbon material reinforced carbon graphite material, which comprises the following uniformly dispersed components: aggregate: pitch coke and carbon black; a low-dimensional carbon material; the binder is modified asphalt and/or high-temperature asphalt; and the dispersion modifier is at least one of tetrahydrofuran, methylbenzene or quinoline. The preparation method of the low-dimensional carbon material reinforced carbon graphite material comprises the following steps: (1) mixing and stirring a dispersion modifier and a binder, and mixing and stirring the dispersion modifier and a low-dimensional carbon material to obtain two turbid liquids; and (2) blending the two turbid liquids, adding aggregate, mixing at low temperature, drying, crushing, screening, forming and roasting to obtain the low-dimensional carbon material reinforced carbon graphite material. According to the low-dimensional carbon material reinforced carbon graphite material adopted by the invention, the low-dimensional carbon material can be uniformly dispersed in the reinforced carbon graphite material, defect initiation in the roasting process is inhibited, crack propagation in a micro area where the low-dimensional carbon material is located in the material service process is inhibited, and the macroscopic mechanical property of the special carbon graphite material is improved.
