Title: Binder for metal powder briquet
Inventor: SHIBATA HIKARI
IPC: C22B1/244
Filed: 1992-12-28
Abstract: PURPOSE:To attain thickening and binding properties and to improve formability by mixing a binder and a metallic assistant into a metal powder in a specified ratio. CONSTITUTION:The binder consists essentially of at least one kind of polybasic acid selected from a group consisting of dimer acids, trimer acids, acrylated fatty acids and maleated fatty acids. From 0.5 to 5wt.% of the binder and 0.5 to 5wt.% of calcium hydroxide, magnesium oxide or zinc hydroxide are mixed into the powder of Al, Fe, Cu or Zn, and the mixture is compacted at 0.1 to 5t/cm<2>. The binder forms a fatty-acid metallic soap which imparts thickening and binding properties to the mixture, and formability and initial strength are imparted. Besides, the soap functions as a surfactant to reduce the surface tension of the powder, hence the wettability is improved, high binder performance is exhibited, and a collapsing strength is kept in aging stability.
