HAP/α-TCP骨水泥制备工艺研究

The Study of Preparation Process on HAP/α-TCP Phosphate Cement

通过对α-TCP体系骨水泥的优化,研究了不同固化液、不同固液比以及不同粉料对骨水泥凝固时间及抗压强度的影响,优选出了以n-HAP/α-TCP为固体粉料,以柠檬酸+柠檬酸钾+丙烯酸-衣康酸为复合固化液,按固液比2.3∶1的α-TCP体系骨水泥,凝固时间为8min,抗压强度达73.59MPa.

The paper studys the effects of different types hardening liquid,different ratio of powder and liquid and different powder on the setting time and compressive strength of it,by optimizing the system of α-TCP phosphate cement,and chooses -HAP/α-TCP as better powder、citric acid+potassium citrate+propenoic acid-itaconae as good hardening liquid and 2.3∶1 as the proper ratio of P/L. It′s setting time is about 8 min,and compression strength is about 73.59 MPa.
