Formation of the Open-Cell Structured Elastomeric Polyurethane Foams using Metal Salt of 12HSA |
| 초록 |
Foaming processes of an elastomeric polyurethane foam having open-cell structures was investigated using a metal salt of 12-hydroxystearic acid as a reactive cell-opening agent. Lithium salt of 12-hydroxystearic acid (Li-12HSA) was properly prepared by the neutralization reaction of lithium hydrate (LiOH·H2O) with 12-HSA in the presence of silicone base-oil. Heat changes during the foaming process were measured with dynamic DSC. Temperature changes with time was also measured during the foaming in the center position of an open-mold. As the results, An inflection point was observed at about 40 sec after start of foaming process, indicating the formation of effective cell structures which is starting time for the thermal insulation during the foaming process. Rate of temperature changes to reach the peak temperatures increased linearly with Li-12HSA concentrations, showing that Li-12HSA could play a role for a catalyst as well as the cell opening agent. |
