Active molybdenum-manganese slurry for solvent-free ceramic metallization packaging and preparation method of active molybdenum-manganese slurry
The invention provides active molybdenum manganese slurry for solvent-free ceramic metallization packaging and a preparation method of the active molybdenum manganese slurry. The slurry is prepared from the following raw materials in parts by mass: 45-60 parts of spherical molybdenum powder, 14-25 parts of manganese-containing glass powder, 20-30 parts of solvent-free resin, 3-5 parts of a solvent-free resin diluent, 1-3 parts of an auxiliary agent and 1-6 parts of an inorganic active additive. The preparation method comprises the following steps: mixing the raw materials according to the ratio, fully stirring and uniformly mixing, and grinding by a three-roller grinder until the fineness is less than or equal to 5 microns. Compared with the traditional solvent type ceramic metallization slurry, the added organic parts are all solvent-free type systems, and the ceramic metallization slurry has the remarkable advantages of being environmentally friendly, free of VOC emission after baking, simple in preparation process and the like; a soldering paste silk-screen printing technology and a reducing atmosphere high-temperature sintering technology are adopted, good combination of the ceramic substrate and the molybdenum-manganese slurry is achieved, and the formed metallization layer is tightly combined with ceramic and is low in porosity, good in air tightness and high in tensile strength.
本发明提供一种无溶剂型陶瓷金属化封装用活性钼锰浆料及其制备方法。该浆料由以下质量份配比的原料制成：45‑60份的球形钼粉，14‑25份的含锰玻璃粉，20‑30份的无溶剂型树脂，3‑5份的无溶剂型树脂稀释剂，1‑3份的助剂，1‑6份的无机活性添加剂。该制备方法是将各组分原料按配比混合，充分搅拌混合均匀后经三辊研磨机研磨至细度≤5μm。相比于传统溶剂型陶瓷金属化浆料，本发明添加的有机部分均为无溶剂型体系，具有环保、烘烤后无VOC排放、制备工序简单等显著优点；采用焊膏丝网印刷技术和还原气氛高温烧结技术，实现了陶瓷基板和钼锰浆料的良好结合，所形成的金属化层与陶瓷结合紧密、孔隙率低、气密性好、抗拉强度高。
