RESIN COMPOSITION, METHOD OF DECOMPOSING URETHANE RESIN AND URETHANE RESIN DECOMPOSITION APPARATUS |
| 摘要 |
<p><P>PROBLEM TO BE SOLVED: To provide a method of improving the surface adhesiveness of foreign substances by controlling the concentration of specified components formed on decomposition since the properties of a reclaimed material deteriorate by the foreign substances such as metals and sand mixed into a decomposition fluid when obtained by chemical decomposition of a urethane resin of an actual waste material. <P>SOLUTION: A resin composition comprises 0.1-5 wt.% the sum of compounds represented by chemical formula 1 and chemical formula 2 or structures having an oxazolidinone ring represented by chemical formula 3 and an imidazolidinone ring represented by chemical formula 4 in the reclaimed resin produced from a urethane decomposition product. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
