ドクターブレード法により作製したアルミナグリーンシートの機械的性質に及ぼす有機添加剤の影響

抄録

The mechanical properties of the green sheet prepared by a doctor blade method were investigated, such as fracture stress, Young's modulus, elongational viscosity, and strain to fracture. The mechanical properties of green sheet depend largely on the added organics. The results on the green sheets are summarized as follows:
(1) The mechanical properties of the green sheet increase with increasing total amount of added organics.
(2) The green sheet has low strength and brittleness less than 1 of the binder to plasticizer ratio, and has high strength and stiffness greater than 1.5. The green sheet exhibits the optimum flexibility at the binder to plasticizer ratio of 1-1.5.
(3) The mechanical properties of the green sheet depend little on the degree of polymerization of PVB by adding the same weight.
