Preparation method of silk-screen printing paste for ceramic sealing
The invention discloses a preparation method of a silk-screen printing paste for ceramic sealing. The preparation method of the paste comprises powder preparation and paste preparation, wherein first powder comprises molybdenum powder, manganese powder and porcelain powder, a ratio of the molybdenum powder (g) to the manganese powder (g) to the porcelain powder (g) is 130:35:35, the first powder and butyl acetate (solvent) are poured into a ball milling bottle according to a ratio of the first powder (g) to the solvent (mL) to an agate ball (g) of 200:160:400, ball milling is performed for 168 hours, natural airing is performed to obtain second powder, and the paste is prepared from ethyl cellulose (g), terpilenol (ml) and the second powder (g) in a ratio of 1:13:23. According to the invention, the paste used in cooperation with the screen printing technology is developed, the uniformity of the thickness of a paste coating layer formed through screen printing of the paste is good, the uniformity of the thickness of a metallization layer formed through surface sintering is excellent, the sealing strength is greatly improved, and the production efficiency is improved.
本发明公开了一种用于陶瓷封接的丝网印刷膏剂的配制方法，膏剂的配制方法包括粉剂配制和膏剂配制，其中：粉剂一成分包含钼粉，锰粉和瓷粉，配比比例为钼粉(g)∶锰粉(g)∶瓷粉(g)＝130∶35∶35；粉剂一和乙酸丁酯(溶剂)按照粉剂一(g)∶溶剂(mL)∶玛瑙球(g)＝200∶160∶400比例倒入球磨瓶中，球磨时间为168小时，自然晾干为粉剂二；膏剂成分配比为：乙基纤维素(g)：松油醇(ml)：粉剂二(g)＝1：13：23；本发明开发了一种配合丝网印刷工艺使用的膏剂，该膏剂采用丝网印刷形成的涂膏层厚度的均匀性好，其表面烧结形成的金属化层厚度的均匀性优异，大大提高封接强度，提高生产效率。
