Slurry for low-temperature co-fired ceramic and preparation method thereof
The invention provides slurry for low-temperature co-fired ceramics and a preparation method thereof.The slurry for the low-temperature co-fired ceramics is prepared from, by weight, 62%-75% of inorganic powder, 20%-30% of solvent, 2%-14% of resin, 0.5%-6.5% of plasticizer and 0.2%-1.5% of dispersing agent, the inorganic powder comprises main powder with D50 being 1-3 micrometers and filling powder with D50 being 0.5-1 micrometer, and the solvent is a solvent. And the weight of the filling powder accounts for 5-20% of the weight of the inorganic powder. By increasing the proportion of the inorganic powder in the slurry, the reduction amplitude of the powder density in the X direction in the salivation forming process is reduced; in addition, by setting the proportion of the main body powder and the filling powder, gaps between the main body powder and the resin can be effectively filled, the raw tape density is improved, the density difference in the X direction and the Y direction is reduced, and the shrinkage rate difference in the two directions is further reduced.
本发明提供了一种低温共烧陶瓷用浆料及其制备方法，所述低温共烧陶瓷用浆料包括以下重量百分比的各组分：无机粉体62％～75％、溶剂20％～30％、树脂2％～14％、增塑剂0.5％～6.5％、分散剂0.2％～1.5％，所述无机粉体包括D50为1～3μm的主体粉体及D50为0.5～1μm的填充粉体，所述填充粉体的重量占所述无机粉体重量的5％～20％。本发明通过增加浆料中无机粉体所占比例，减小了流涎成型过程中X方向上粉体密度减小的幅度；另外，通过设置主体粉体及填充粉体的比例，可有效填充主体粉体及树脂间缝隙，提高生带密度，降低XY方向密度差异，进一步减小两个方向的收缩率差异。
