Water-based ceramic slurry, preparation method of ceramic film and chip multilayer ceramic capacitor
The invention belongs to the technical field of ceramic capacitors, and particularly relates to water-based ceramic slurry, a preparation method of a ceramic film and a chip multilayer ceramic capacitor. The water-based ceramic slurry provided by the invention comprises barium titanate powder, polycarboxylate, polyacrylate, phthalate, an antifoaming agent and water according to a specific weight part ratio, wherein water is used as a solvent; polycarboxylate is used as a dispersing agent; polyacrylate is used as a binding agent; phthalate is used as a plasticizer; the components have a synergistic effect, so that the water-based ceramic slurry is endowed with good rheological property, a ceramic film formed by tape casting of the water-based ceramic slurry is smooth and compact in surfaceand good in mechanical property, surface defects such as cracks do not easily occur, and the quality of a ceramic film layer is greatly improved.
本发明属于陶瓷电容器技术领域，尤其涉及一种水基陶瓷浆料、陶瓷薄膜的制备方法和片式多层陶瓷电容器。本发明提供的水基陶瓷浆料，包括具有特定重量份配比的钛酸钡粉体、聚羧酸盐、聚丙烯酸酯、邻苯二甲酸酯、消泡剂和水，其中，以水为溶剂，以聚羧酸盐为分散剂，以聚丙烯酸酯为粘结剂，以邻苯二甲酸酯为增塑剂，上述各组分间协同作用，赋予了水基陶瓷浆料良好的流变性能，使得由该水基陶瓷浆料经流延形成的陶瓷薄膜表面平整致密，机械性能好，不容易出现裂纹等表面缺陷，大大提升了陶瓷膜层的质量。
