Biodegradable polyurethane capsules and manufacturing method thereof |
| abstract |
The present invention relates to biodegradable polyurethane capsules for molded product of polyurethane foam and to methods for manufacturing the same. the inventive biodegradable polyurethane capsule comprises a powder made from a biodegradable material, first coating layer of calcium alginate gel formed on the surface of said power and second coating layer of foamable polyurethane resin formed on the surface of said first coating layer. Products manufactured from the biodegradable polyurethane capsule according to the present invention can be widely used as heat isolating materials and heat isolating structural materials because the basic physical properties such as heat insulation are good. And, since the biodegradable material inside the capsule is decomposed by microbes in the nature after a certain period, the efficiency of destruction is considerably improved, so it is possible to minimize the conventional problems of soil, air, and sea pollution caused by fill-in or incineration of the wastes of polyurethane molded foam product. |
