在这项研究中,研究了几种添加剂对聚合磷酸钙水泥的凝固行为和机械性能的影响。该水泥源自聚羧酸(PCA)和磷酸钙水泥(CPC)粉末,其中含有等摩尔量的磷酸四钙(TTCP)和磷酸二钙(DCPA)。通过添加磷酸三钠和氟化物如氟化亚锡、氟化锆(IV)和氟化钛(IV),观察到PCA-CPC水泥中凝固反应的延迟。研究发现,增加这些添加剂的浓度会降低水泥的机械​​强度。然而,通过联合使用 8% (w/w) 氟化亚锡和 10% (w/w) 酒石酸,PCA-CPC 水泥的凝固和机械性能均得到改善。通过添加醋酸钙、甲基丙烯酸钙、硫酸锆(IV)和膦酰基乙酸,PCA-CPC水泥的机械​​性能也得到改善。
In this study, the effects of several additives on the setting behavior and mechanical properties of polymeric calcium phosphate cements were investigated. The cements were derived from a polycarboxylic acid (PCA) and a calcium phosphate cement (CPC) powder that consisted of equimolar amounts of tetracalcium phosphate (TTCP) and dicalcium phosphate (DCPA). Retardation of the setting reaction in the PCA-CPC cements was observed by adding tribasic sodium phosphate and fluorides such as stannous fluoride, zirconium(IV) fluoride and titanium(IV) fluoride. It was found that increasing the concentration of these additives decreased the mechanical strength of the cements. However, improvements in both setting and mechanical properties for the PCA-CPC cements were observed by the combined use of 8% (w/w) stanous fluoride and 10% (w/w) tartaric acid. The mechanical properties of the PCA-CPC cement also were improved by adding calcium acetate, calcium methacrylate, zirconium(IV) sulfate and phosphonoacetic acid.
