Title: Binder Composition for Metal Injection Molding
Inventor: MIN DOO SIK
IPC: C08L59/02
Filed: 2020-09-24
Abstract: The present invention relates to a binder composition for metal powder injection molding. Particularly, the present invention relates to a binder composition for metal powder injection molding which allows rapid defatting, facilitates setting of a flow condition in an injection process, and minimizes defects in defatting, such as swelling, carbonization of a low-molecular weight binder or other internal defects during a defatting process. The binder composition for metal powder injection molding includes 10-50 wt% of a high-viscosity polyoxymethylene polymer and 50-90 wt% of a low-viscosity polyoxymethylene polymer. The binder composition for metal powder injection molding includes polyoxymethylene alone, wherein the polyoxymethylene is produced depending on viscosity without introducing any other monomer during a polymerization process of polyoxymethylene. Therefore, the binder composition is advantageous in that the composition requires lower production costs and is economical, as compared to a conventional polymerization process which includes controlling viscosity to control the rate of decomposition in a vapor-state acid. The binder composition is also advantageous in that the composition shows excellent injection properties and defatting/sintering properties, as compared to the combined use of polyoxymethylene with another polymer resin, such as polyolefin or polyamide.
