摘　　要：为进一步提高无机反射涂料与基体材料间的黏结强度,研究了球磨机研磨涂料固化剂(AlPO_(4))获得M-AlPO_(4)制作涂料,采用激光粒度仪、X-射线衍射仪、扫描电子显微镜对M-AlPO4进行性能表征,以AlPO_(4)为空白对照。测试了M-AlPO_(4)制作的涂料黏结强度,用红外光谱仪、扫描电子显微镜、能谱仪表征其微观组成结构,并以AlPO_(4)制作的涂料作空白对照。结果发现,研磨使M-AlPO_(4)具有更小的颗粒尺寸和晶粒尺寸,使M-AlPO_(4)在涂料中分布更均匀,并提高Si-O聚合程度和分布的均匀程度,最终提高涂料的黏结强度。该研究能进一步拓宽该涂料的使用范围和延长使用寿命。In order to improve the bond strength between inorganic reflective coatings and matrix material.M-AlPO_(4)was obtained by grinding the curing agent(AlPO_(4))with ball milling,and was used to prepare the coating.M-AlPO_(4)was characterized by laser particle size analyzer,X-ray diffractometer and scanning electron microscope,AlPO_(4)was used as the control.The bond strength of the coating prepared by M-AlPO_(4)was tested.The microstructure of the coating was also characterized by infrared spectrometer,scanning electron microscope and energy dispersive spectrometer.The coating prepared by M-AlPO_(4)was used as blank control.The results show that grind reduces the particle size and grain size of M-AlPO_(4),facilitates more even distribution of M-AlPO_(4),improves the distributed evenness and the polymerization degree of Si-O polymer in the coating,enhances the bond strength of the coating.The methods can improve the durability and extend the further application range of coating.
