Ceramic tape casting slurry, preparation method thereof and ceramic tape casting green tape
The invention provides ceramic tape-casting slurry and a preparation method thereof and a ceramic tape-casting green tape, and belongs to the field of semiconductor test materials, the ceramic tape-casting slurry comprises 30-55 wt% of CBS ceramic powder, 25-50 wt% of a solvent, 0.5-3 wt% of a dispersant, 5-12 wt% of a binder and 3-10 wt% of a plasticizer, the solvent is a ternary mixed solvent of isopropanol, xylene and ethanol according to a mass ratio of 3-6: 3-1: 4-3, and the plasticizer is an organic solvent. The binder is PVB resin with low hydroxyl content, the hydroxyl content of the binder ranges from 11 wt% to 13.5 wt%, and the molecular weight of the binder ranges from 50000 to 80000. Through the treatment scheme disclosed by the invention, the flocculation phenomenon in the slurry ball milling and standing processes is effectively inhibited.
本发明提供了一种陶瓷流延浆料及其制备方法和陶瓷流延生带，属于半导体测试材料领域，所述陶瓷流延浆料包括30～55wt％的CBS陶瓷粉体、25～50wt％溶剂、0.5～3wt％分散剂、5～12wt％粘结剂、3～10wt％增塑剂，所述溶剂为异丙醇、二甲苯、乙醇三元混合溶剂，质量比为3～6：3～1：4～3，所述粘结剂为低羟基含量PVB树脂，其羟基的含量范围为11～13.5wt％，分子量为50000～80000。通过本公开的处理方案，有效抑制浆料球磨和静置过程中的絮凝现象。
