Abstract: The present invention provides a binder for manufacturing an inorganic sintered body that has excellent adhesiveness upon heat pressing and thermal decomposability and, especially when used as a binder for a ceramic green sheet, provides a ceramic green sheet having sufficient mechanical strength and flexibility. The present invention also provides a paste for manufacturing an inorganic sintered body, a ceramic green sheet, and a ceramic laminate individually manufactured using the binder for manufacturing an inorganic sintered body. The present invention provides a binder for manufacturing an inorganic sintered body containing a graft copolymer having a unit including polyvinyl butyral and a unit including a poly(meth)acrylic compound, the polyvinyl butyral having a polymerization degree of 800 to 5000, a hydroxy group content of 20 to 40 mol %, and a butyralization degree of 60 to 80 mol %, the unit including a poly(meth)acrylic compound having a glass transition temperature of 0 to 110° C.

Abstract translation: 本发明提供了一种用于制造具有优异的热压粘合性和热分解性的无机烧结体的粘合剂，特别是当用作陶瓷生片的粘合剂时，提供了具有足够机械强度和柔性的陶瓷生坯片。 本发明还提供了一种用于制造无机烧结体，陶瓷生片和陶瓷层压体的浆料，该粘合剂使用用于制造无机烧结体的粘结剂单独制造。 本发明提供一种用于制造无机烧结体的粘结剂，其包含具有包含聚乙烯醇缩丁醛的单元的接枝共聚物和包含聚（甲基）丙烯酸化合物的单元，聚合度为800至5000的聚乙烯醇缩丁醛，羟基含量 为20〜40摩尔％，丁缩醛化度为60〜80摩尔％，该单元包含玻璃化转变温度为0〜110℃的聚（甲基）丙烯酸类化合物。
