摘　　要：近年来,高精度、高强度的复杂件连接方式受到广泛关注。本文以无定形磷酸盐胶粘剂为基体,掺杂Si、B 4C和ZrW_(2)O_(8)等填料及固化剂,通过调整不同比例,成功制备了一系列具有不同热膨胀系数的磷酸盐无机胶粘剂。这些胶粘剂被应用于β-锂霞石微晶玻璃的粘接,并有效调控了其热膨胀系数。通过X射线衍射、傅里叶变换红外光谱、同步热分析仪、扫描电子显微镜、粘接强度测试及热膨胀系数测试等方法对粘接件进行了全面的测试和表征。测试结果显示,经ZrW_(2)O_(8)改性的磷酸盐胶粘剂在粘接β-锂霞石微晶玻璃时展现出卓越的性能,经过热处理的粘接件在20~100℃的热膨胀系数可达0.12×10^(-6)K^(-1),而粘接强度最高可达6.5 MPa。In recent years,high-precision and high-strength connections of complex parts have received widespread attention.This study employed amorphous phosphate adhesive as the base,incorporating fillers and curing agents including Si,B 4C,and ZrW_(2)O_(8),to prepare a series of phosphate inorganic adhesives with varied coefficients of thermal expansion by adjusting the proportion.These adhesives were utilized for bondingβ-lithium nesosilicate microcrystalline glass,effectively controlling its coefficient of thermal expansion.The bonded joints were thoroughly tested and characterized using techniques such as X-ray diffraction,Fourier transform infrared spectroscopy,simultaneous thermal analyzer,scanning electron microscopy,bonding strength testing,and coefficient of thermal expansion testing.The findings indicat that the phosphate adhesive modified with ZrW_(2)O_(8)demonstrates outstanding performance in bondingβ-lithium nesosilicate microcrystalline glass,with heat-treated bonded joints exhibiting a coefficient of thermal expansion of 0.12×10^(-6)K^(-1)over the temperature range of 20~100℃,and a maximum bonding strength of 6.5 MPa.
