The invention discloses shield tunneling machine main bearing sealing grease and a preparation method thereof. The sealing grease is prepared from, by mass, 10%-20% of base oil, 1%-5% of corrosion inhibitor, 2%-6% of fibrous materials, 10%-20% of lubricating grease, 15%-24% of tackifier, 40%-50% of powdery filler, 0.5%-3% of ionic liquid and 1%-4% of graphene. According to the shield tunneling machine main bearing sealing grease and the preparation method thereof, by adding the ionic liquid and the graphene, the wear resisting performance and lubricating performance of the sealing grease are improved, the water washing loss amount of the sealing grease is reduced, the water jet resistance of the sealing grease is remarkably improved, and the sealing grease has better sealing performance.
