The invention discloses a porous wearproof biological ceramic material and a preparation method thereof, relating to the technical field of biological ceramic materials. The biological ceramic material is prepared from the following raw materials in parts by weight: 40-60 parts of tricalcium phosphate, 15-30 parts of calcium silicate, 10-20 parts of zirconium silicate, 6-12 parts of attapulgite, 10-20 parts of nanometer titanium dioxide, 3-8 parts of boron nitride, 1-5 parts of aluminium trioxide, 3-8 parts of wood fiber, 1-3 parts of sodium carboxymethylcellulose and 0.5-3 parts of a stabilizer. The preparation method of the porous wearproof biological ceramic material comprises the following steps of stirring, mixing, ball milling, and firing to form into shape. The biological ceramic material is high in porosity rate, resistant to wear, fracture and stretching, strong in flexibility, excellent in biological activity, easy in regeneration treatment, and suitable for being used as an ideal bone repairing and replacing material.
