Preparation and characterization of thermoplastic polyurethane microcapsules for rubber manufacture |
| 초록 |
It is essential to encapsulate vulcanizing agent and vulcanizing acceleration agent to block the heat generated by the kneading and molding process of rubber product and prevent rubber from being vulcanized before vulcanization process. And also microcapsules have to melt in vulcanization process and release vulcanizing agent and vulcanizing acceleration agent in the mixing process. Therefore microcapsulation would ultimately promote the formability and ease of the manufacturing process of rubber product. As the wall material, thermoplastic polyurethane(TPU) that can control the content of the hard segment and the soft segment to obtain the desired melting point and mechanical strength. And microcapsulation thermoplastic polyurethane was done by solvent evaporation method. To determine that the microcapsules can be applied in the actual process indirectly, microcapsules were heated in the oven and rotated for 30 min at 3300 rpm. |
