Solvent system, barium titanate tape casting slurry and ceramic diaphragm
The invention provides a solvent system, barium titanate tape casting slurry and a ceramic diaphragm, and relates to the technical field of materials. The solvent system provided by the invention comprises methyl ethyl ketone, absolute ethyl alcohol, xylene and cyclohexanone in a specific ratio, has good solubility for powder and auxiliaries, can be used in tape casting slurry, avoids agglomeration, and relieves the peeling defect generated in the drying process of a tape casting diaphragm. The barium titanate tape casting slurry provided by the invention comprises barium titanate powder, the solvent system, a surfactant, a deflocculating agent, a plasticizer and an adhesive according to a specific ratio. The barium titanate tape casting slurry has the advantages that the viscosity is stable, the barium titanate powder is uniformly dispersed, all the components are matched with one another, the slurry is subjected to tape casting, ceramic diaphragms with the thickness of 2 microns or below can be prepared, and the prepared ceramic diaphragms are smooth, good in uniformity and high in quality.
本发明提供了一种溶剂体系、钛酸钡流延浆料和陶瓷膜片，涉及材料技术领域。本发明提供的溶剂体系包括特定配比的甲基乙基酮、无水乙醇、二甲苯和环己酮，该溶剂体系对于粉体和助剂的溶解性好，能够用于流延浆料中，避免出现团聚，缓解流延膜片干燥过程中所产生的“起皮”缺陷。本发明提供的钛酸钡流延浆料，包括特定配比的钛酸钡粉体、溶剂体系、表面活性剂、解凝剂、增塑剂和黏合剂。该钛酸钡流延浆料黏度稳定，钛酸钡粉体分散均匀，各个组分之间相互配合，以此浆料进行流延能够制备得到厚度为2μm及以下陶瓷膜片，且制备得到的陶瓷膜片光滑、均匀度好、质量高。
