ZrW2O8对磷酸盐无机胶粘剂结构与性能的影响
Effect of ZrW2O8 on Structure and Properties of Phosphate Inorganic Adhesives
摘要
Abstract
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,B4 C,and ZrW2 O8,to prepare a series of phosphate inorganic adhesives with varied coefficients of thermal expansion by adjusting the proportion.These adhesives were utilized for bonding β-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 ZrW2O8 demonstrates outstanding performance in bonding β-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.关键词
