摘　　要：以聚丙烯酸酯乳液为粘合剂,采用水基流延成型制备了镍电极多层陶瓷电容器(Ni-MLCC)。利用扫描电子显微镜对膜片表面形貌进行了分析,研究了该水性粘合剂对Ni-MLCC陶瓷浆料黏度、膜片拉伸强度以及所制电容器的电性能的影响。结果表明:粘合剂的用量以质量分数10%为最佳,流延成型所得膜片表面光滑,无缺陷,瓷粉分散均匀,所制备电容器的各项电性能符合EIA-Y5V规范。Ni electrode-MLCC was prepared by aqueous tape-casting process using acrylic emulsion as binder. SEM was used to analysis surface morphology of green sheets. The effect of the aqueous binder on viscosity the Ni electrode-MLCC ceramic slurry, tensile strength of the green sheets and the electric properties of prepared Ni electrode-MLCC was investigated. The results show that the optimum dosage of the acrylic binder is 10%(mass fraction). The sheets have smooth surface without defect. Ceramic powders are disp...
