摘　　要：目的：研制一种可取代ＶＬＣ－１型粘结剂的新型可见光固化粘结剂。方法：按照有关试验标准和参考资料测定研制的新型粘结剂和ＶＬＣ－１型、ＤｕｒａｆｉｌＢｏｎｄ粘结剂的剪切粘结强度（ＳＢＳ）、压缩强度（ＣＳ）、径向拉伸强度（ＤＴＳ）、表面硬度（Ｈｖ）和聚合程度（ＤＰ）。结果：新型粘结剂的ＣＳ、ＤＴＳ、Ｈｖ、ＳＢＳ和ＤＰ分别为１９６．２ＭＰａ、４１．９ＭＰａ、２８６．８ＭＰａ、２８．４ＭＰａ和６３．１％，明显高于ＶＬＣ－１型粘结剂（Ｐ＜０．０１）。结论：ＶＬＣ－２型光固化粘结剂具有良好的物理机械性能，可取代ＶＬＣ－１型粘结剂。Aim:To develop a new visible light-cured bonding agent to replace VLC-1 type bonding agent.Methods: The shear bond strength(SBS), compress strength(CS), diametral tensile strength (DTS), surface hardness(Hv), and degree of polymerization(DP) of the new bonding agent, VLC-1 type and Durafill Bond were determined in accordance with relevant test standard and reference. Results:The CS, DTS, Hv, SBS and DP of the new bonding agent were 196.2MPa, 41.9MPa, 286.8MPa, 28.4MPa, and 63.1% respectively. The data were morethan the data of VLC-1 type(P<0.01). Conclusions:The VLC-2 type bonding agent can replace the VLC-1 type bonding agent due to its excellent physical and mechanical properties.
