Title:
粉粒体の造粒成形用バインダ及び造粒成形物
Document Type and Number:
Japanese Patent JP3986291
Kind Code:
B2
Abstract:
Conventional binders require water for granulation, are poor in shape retention, generate a large amount of smoke when used in granulated moldings, thus deteriorating the working atmosphere, and causes excessive heating of granulated moldings, and therefore there are many disadvantages to limit their use. The binder of the invention is compounded with a resin having a softening point suitable as a binder resin for toners, preferably 100° C. or less, for example polyol resin, styrene-acrylic copolymer or polyester resin. As the binder, waste toners can be utilized. The binder does not require addition of water and is excellent in water resistance, and is thus effective for production of steel-making flux particularly from aluminum residues such as alumidoloss and aluminum ash.
