Abstract

본 발명은 사출성형법에 의하여 금속이나 세라믹 분말의 소결체를 제조시 사용되는 결합제에 관한 것으로, 결합제의 성분 및 2함량을 적절히 제어하므로서 결합제간의 상용성과 분말간의 점착특성이 우수하여 사출성형시 결합제와 분말의 분리를 방지할 수 있으며 결합제 제거시 열분해 특성이 우수한 분말사출성형용 결합제를 제공하고자 하는데, 그 목적이 있다.The present invention relates to a binder used in the manufacture of a sintered body of metal or ceramic powder by injection molding. The present invention relates to a binder and a powder during injection molding because of excellent compatibility between the binder and adhesion between the powders by controlling the components and the content of the binder appropriately. The purpose of the present invention is to provide a powder injection molding binder which can prevent the separation and has excellent thermal decomposition property when removing the binder.

상기한 목적을 달성하기 위한 본 발명은 중량%로 폴리아마이드레진:20~40%, 에틸렌-비스-스테아라마이드:30% 이하, 나머지:올리아마이드, 또는 폴리아마이드레진:20~40% 및 나머지:올리아마이드로 조성되며, 구조중에 아마이드기를 포함하는 분말사출성형용 결합제를 제공함을 그 요지로 한다.The present invention for achieving the above object is a polyamide resin: 20-40% by weight, ethylene-bis- stearamide: 30% or less, the rest: olamide, or polyamide resin: 20-40% and the rest : It is made into the point which provides the powder injection molding binder which consists of an amide and contains the amide group in a structure.
