Development of Environmentally Friendly Binder in Extrusion Molding

Abstract:

A new kind of binder was developed in extrusion molding. It included four ingredients: ethylene glycol acetate (60%~85% (mass/mass, as follows)), ethyl cellulose (10%~30%), ethylene glycol polyoxyethylene ether (5%~10%), polyethylene glycol stearate (0.8%~3%). The components of binder were compatible with thermodynamic conditions, so the binder was well-distributed in molecule level. The new binder is actual nontoxic, secure and environmentally friendly. The forming property of the binder is so excellent that it can load 54% ~ 56% (vol. /vol.) cemented carbide powders. The rods produced by this new binder provide high strength, stable performance, homogeneous microstructure.
