A study on green tapes for LOM with water-based tape casting processing

摘要

A commercial styrene-acrylic latex binder has been investigated as eligible binder for aqueous Al_2O_3 suspensions tape casting processing. This paper focuses on the rheological behavior and tape casting processing of aqueous slurries with latex binder system. In this experiment, the green tapes have a smooth surface, good toughness and homogeneous structure. Moreover, the green tapes can coil continuously by a roller as the primal materials for laminated object manufacturing (LOM) technology. Because the T_g of latex binder is under the room temperature, the green tapes can laminate to a part in room temperature. The surface of green tapes and interfacial character of laminated green parts are also studied by SEM. The result shows that the green tape is suitable to LOM (laminated object manufacturing) technology.
