| titleOfInvention | Recovering method highly efficiently from waste polyurethane using recycled polyol |
| abstract | The present invention relates to a method for recovering a waste polyurethane as a polyol by a glycol depolymerization reaction, and more particularly, to a method for recovering a waste polyurethane from a waste polyurethane using a recycled polyol. More specifically, 50 to 200 parts by weight of regenerated polyol and 50 to 500 parts by weight of glycols, and heating and stirring at 120 to 300 ° C .; Adding 50 to 150 parts by weight of an amine-based oligomer and the vegetable oil, 0.1 to 50 parts by weight of an organometallic catalyst or an amine catalyst to the mixture of the first stage and reacting at a temperature of 170 to 400 ° C; And a third step of sufficiently reacting the mixture of the second step to convert the waste polyurethane into a polyol due to glycol depolymerization and then adding 0.001 to 10 parts by weight of an anti-emulsifier at a temperature of 160 to 180 ° C. The present invention relates to a high-efficiency recovery method of polyol from waste polyurethane. |
