中文摘要：
用聚乙烯醇缩丁醛作为配制硼硅酸盐玻璃/α-Al2O3流延浆料的粘结剂,流延成型制备玻璃/Al2O3生料带,研究了PVB对玻璃/Al2O3复合料生料带密度、力学性能、微观结构及其烧结性能等的影响。实验结果表明,随着PVB分子量和羟基含量减小,生料带拉伸强度和断裂伸长率降低、体积密度增加、生料带排胶热分解温度降低,对烧结瓷体密度和介电性能的影响较小。
英文摘要：
In this paper,the borosilicate glass /Al2O3tape was prepared with the binder system of polyvinyl butyral（ PVB） by tape casting. The effect of PVB on the bulk density,the microstructure and mechanical property of green tape was detailly studied. The results showed that with the decreasing of molecular weight and hydroxyl content of PVB,the decomposition temperature,the tensile strength and breaking elongation of green tape were reduced; the bulk density was increased; the density and dielectric properties of the sintered ceramic did not change obviously.
