Electrode protective agent and chamfering method of multilayer chip ceramic capacitor sintered body
The invention relates to an electrode protective agent and a chamfering method of a multilayer chip ceramic capacitor sintered body, and belongs to the technical field of multilayer chip ceramic capacitor processing. The electrode protective agent comprises the following components in percentage by weight: 0.2-2% of a humectant, 0.5-5% of an antioxidant, 0.1-1% of a metal complexing agent and the balance of deionized water. The chamfering method of the multilayer chip ceramic capacitor sintered body sequentially comprises the steps of presoaking, canning, chamfering and drying, in the canning step, an organic acid solution is added into chamfering grinding liquid, ceramic on the surface of the multilayer chip ceramic capacitor sintered body is removed through the organic acid solution, chamfering is carried out with the assistance of aluminum oxide and grinding powder, and then the multilayer chip ceramic capacitor sintered body is obtained. In this way, compared with pure powder mechanical collision chamfering, surface ceramic can be removed more efficiently, so that an end face electrode is fully exposed. And in order to avoid the corrosion of the organic acid solution to the electrode of the multilayer chip ceramic capacitor sintered body, the electrode needs to be pre-impregnated in an electrode protective agent before canning.
本发明涉及一种电极保护剂及多层片式陶瓷电容器烧结体的倒角方法，属于多层片式陶瓷电容器加工的技术领域。该电极保护剂，包括以下按重量百分比计的组分：0.2～2％保湿剂、0.5～5％抗氧化剂、0.1～1％金属络合剂，余量为去离子水。多层片式陶瓷电容器烧结体的倒角方法依次包括预浸、装罐、倒角和烘干的步骤，在装罐步骤中在倒角研磨液中加入有机酸溶液，利用有机酸溶液先去除多层片式陶瓷电容器烧结体表面陶瓷，辅以氧化铝和研磨粉进行倒角，这样比单纯粉末机械碰撞倒角能更高效地去除表面陶瓷，以使得端面电极充分的裸露。而为了避免有机酸溶液对多层片式陶瓷电容器烧结体的电极腐蚀，所以在装罐前需要在电极保护剂中进行预浸处理。
