The invention belongs to the technical field of ceramic membrane filters, and discloses a high thermal shock resistance ceramic membrane supporting body and a preparation method thereof. The high thermal shock resistance ceramic membrane supporting body is prepared from fused quartz, boron nitride, a pore-forming agent and a binding agent, wherein the amount of the fused quartz and the boron nitride meets the following conditions: the mass percentage of the fused quartz is 90%-99%; and the mass percentage of the boron nitride 1%-10%. The method comprises the following steps of: mixing the fused quartz, the boron nitride, the pore-forming agent and the binding agent, molding, and then sintering to obtain the high thermal shock resistance ceramic membrane supporting body, wherein the sintering temperature is 1000 DEG C-1200 DEG C. The ceramic membrane supporting body prepared by the invention has the characteristics of high mechanical strength, large permeation flux, high thermal shock resistance, relatively low cost, good stability and the like.
