[0032] Example 1
[0033] A preparation method of calcium phosphate-based bone repair scaffold, characterized in that, comprising the following steps:
[0034] (1) Mix the calcium phosphate bone cement solid phase powder and the solidification liquid, and the solid-liquid ratio of the calcium phosphate bone cement solid phase powder and the solidification liquid is 1g: 0.45mL, and stir evenly to obtain a calcium phosphate bone cement slurry. The solid phase powder includes polyethylene glycol, α-tricalcium phosphate, strontium-doped octacalcium phosphate and / or strontium-doped amorphous calcium phosphate; in the solid phase powder, the molar ratio of strontium and calcium is: strontium: calcium = 0.1:1; the molar ratio of the sum of calcium and strontium to phosphorus is: calcium+strontium:phosphorus=1.1:1; the mass fraction of polyethylene glycol in the solid phase powder is 0.5%;
