Abstract： |
The invention relates to a preparation method for calcium phosphate aggregate cement that can degradate in human body, which comprises: preparing said cement powder by alpha-type tricalcium phosphate, calcium biphosphate and calcium carbonate powder; adding chitose microsphere in prepared analog body fluid, clearing and drying to mix with said solid powder to prepare composite powder; using buffle solution to add baking soda and sodium alginate to prepare solidification liquid; finally, mixing the powder and liquid to prepare composite slurry. |
