Ceramic tape casting slurry and preparation method thereof
The invention provides ceramic tape casting slurry and a preparation method thereof. The ceramic tape casting slurry comprises the following components in percentage by weight: 30%-55% of ceramic powder, 0.5%-2% of a dispersing agent, 3%-10% of a binder, 3%-10% of a plasticizer and the balance of an alcohol and ester mixed solvent. In the alcohol and ester mixed solvent, the mass ratio of the alcohol solvent to the ester solvent is 1: 1, the alcohol solvent is a mixed solution of ethanol and glycerol, and the mass ratio of the ethanol to the glycerol is (9-9.5): (1-0.5); the ester solvent is a mixed solution of ethyl acetate and propyl acetate, and the mass ratio of ethyl acetate to propyl acetate is (9.5-9.8): (0.5-0.2). The adopted alcohol and ester mixed solvent is high in safety, the materials are easy to obtain, the system is stable, ethyl alcohol, glycerol, ethyl acetate and propyl acetate are all organic solvents, the organic solvent system is stable, the volatilization speed is high, the solubility for organic materials such as a dispersing agent, a binding agent and a plasticizer is high, and the stability of the system is high. The selection range of the dispersing agent, the binding agent and the plasticizer is widened, and the stability of the system is improved.
本发明提供了一种陶瓷流延浆料及其制备方法，按重量百分比计，包含30％‑55％陶瓷粉体、0.5％‑2％分散剂、3％‑10％粘结剂、3％‑10％塑化剂，余量为醇类和酯类混合溶剂。其中，醇类和酯类混合溶剂中，醇类溶剂和酯类溶剂的质量比为1:1，醇类溶剂为乙醇与丙三醇的混合溶液，乙醇与丙三醇质量比为9～9.5：1～0.5；酯类溶剂为乙酸乙酯与乙酸丙酯的混合溶液，乙酸乙酯与乙酸丙酯质量比为9.5‑9.8:0.5‑0.2。本发明采用的醇类和酯类混合溶剂安全性高、材料易得，且体系稳定，乙醇、丙三醇、乙酸乙酯、乙酸丙酯均为有机溶剂，具备有机溶剂体系稳定、挥发速度快的性能，对于分散剂、粘结剂、塑化剂等有机物料的溶解性强，有助于提升分散剂、粘结剂、塑化剂的选择范围，并提升体系稳定性。
