The invention discloses a high thermal conductivity silicon carbide ceramic material and a preparation method thereof. The high thermal conductivity silicon carbide ceramic material is characterized by being prepared from the following raw materials in parts by weight: 70-80 parts of silicon carbide, 9-12 parts of silicon nitride, 4-6 parts of stainless steel powder, 6-8 parts of titanium powder, 2-3 parts of polyaluminum chloride, 1-2 parts of a silane coupling agent KH-570, 4-5 parts of cryolite powder, 3-4 parts of quartz, 2-4 parts of sintering additives and 80-100 parts of deionized water. The stainless steel powder added increases the sintering compactness of the ceramic and reduces the sintering temperature, so that the resources are saved; silicon nitride is added to improve the hardness, thermal conductivity and insulating property of the ceramic are improved; the added sintering additives improve the sintering performance of the ceramic and increase the sintering density, so that the service life of the ceramic is prolonged.
