摘要/Abstract

摘要： 目的:评价硅烷偶联剂用量对硼酸铝晶须增强树脂挠曲强度的影响。方法:使用0%、1%、2%、3%、4%质量分数的Z-6030对硼酸铝晶须进行表面处理;将处理过的晶须和树脂基质按一定的配方合成5组热固化型复合树脂,每组6个试件,在120℃的烘箱内固化1 h后,按ISO-4049标准进行三点弯曲测试。每组随机选1个试件,进行断面扫描电镜观察。采用SAS 9.2软件包对结果进行均数间两两比较。结果:硅烷偶联剂用量为2%质量分数时,增强树脂的挠曲强度（117.93±11.9）MPa最高,与其余4组差异显著。结论:硅烷偶联剂的用量对晶须的增强效果有显著影响,过多或过少均会降低复合树脂的挠曲强度。

Abstract: PURPOSE: To evaluate the effect of amount of silane coupling agent on flexural strength of dental composite resins reinforced with aluminium borate whisker (ABW). METHODS: ABW was surface-treated with 0%, 1%, 2%, 3% and 4% silan coupling agent(γ-MPS), and mixed with resin matrix to synthesize 5 groups of composite resins. After heat-cured at 120℃ for 1 h, specimens were tested in three-point flexure to measure strength according to ISO-4049. One specimen was selected randomly from each group and observed under scanning electron microscope (SEM). The data was analyzed with SAS 9.2 software package. RESULTS: The flexural strength（117.93±11.9Mpa）of the group treated with 2% silane coupling agent was the highest, and significantly different from that of the other 4 groups (α=0.01). CONCLUSIONS: The amount of silane coupling agent has impact on the flexural strength of dental composite resins reinforced with whiskers; The flexual strength will be reduced whenever the amount is higher or lower than the threshold.
