Ceramic slurry, preparation method of ceramic casting film and chip type multilayer ceramic capacitor
The invention belongs to the technical field of ceramic capacitors, and particularly relates to a ceramic slurry, a preparation method of a ceramic casting film and a chip type multilayer ceramic capacitor. The provided ceramic slurry comprises barium titanate powder, castor oil, polyvinyl butyral, di-n-butyl phthalate, n-butyl alcohol, ethylene glycol and anhydrous ethanol according to a specificweight part ratio, wherein anhydrous ethanol is used as a solvent; castor oil is used as a dispersing agent, polyvinyl butyral is used as a binding agent, di-n-butyl phthalate is used as a plasticizer, n-butyl alcohol and ethylene glycol are used as a defoaming agent, and the ceramic slurry is endowed with a good rheological property through the synergistic effect of the components, so that a ceramic casting film formed by casting the ceramic slurry is smooth and compact in surface.
本发明属于陶瓷电容器技术领域，尤其涉及一种陶瓷浆料、陶瓷流延薄膜的制备方法和片式多层陶瓷电容器。本发明提供的陶瓷浆料，包括具有特定重量份配比的钛酸钡粉体、蓖麻油、聚乙烯醇缩丁酯、邻苯二甲酸二正丁酯、正丁醇、乙二醇和无水乙醇，其中，以无水乙醇为溶剂，以蓖麻油为分散剂，以聚乙烯醇缩丁酯为粘结剂，以邻苯二甲酸二正丁酯为增塑剂，以正丁醇和乙二醇为消泡剂，上述各组分的协同作用，赋予了陶瓷浆料良好的流变性能，使得由该陶瓷浆料经流延形成的陶瓷流延薄膜表面平整致密。
