Abstract

본 발명은 벌집형상의 허니콤 구조체 제조방법에 관한 것으로, 압출물질을 압축성형가능하도록 페이스트 상태로 만드는 단계와, 페이스트를 압출성형하여 성형물을 만드는 단계와, 상기 성형물을 건조시키는 단계와, 건조된 성형물로 허니콤 구조체를 만들기 위해 레이저 가공기로 셀을 형성하는 단계와, 상기 허니콤 구조체를 소결하여 완성하는 단계로 허니콤 구조체를 제조함으로써 압출다이의 구조가 간단해지고, 건조시 깨짐방지용으로 사용되는 결합제의 사용량이 줄거나 불필요하여 소결후의 기계적 강도가 증가되며, 셀의 형상의 원형으로 형성하는 것이 가능하여 소결시 응력 집중현상이 제거됨으로써 기계적, 열적강도를 증가시킬수 있고 소결수축과 변형을 감소시킬 수 있다.The present invention relates to a honeycomb-shaped honeycomb structure manufacturing method, comprising the steps of making the extruding material in a paste state so as to be compression-molded, extrusion molding the paste to form a molded article, drying the molded article, dried The honeycomb structure is manufactured by forming a cell with a laser processing machine to make a honeycomb structure from a molded product, and sintering and completing the honeycomb structure to simplify the structure of the extrusion die, and to prevent cracking during drying. As the amount of binder used is reduced or unnecessary, the mechanical strength after sintering is increased, and it is possible to form a circular shape of the cell, so that the stress concentration phenomenon during sintering can be eliminated, thereby increasing the mechanical and thermal strength, and reducing sintering shrinkage and deformation. Can be.
