| titleOfInvention | Vegetable oil polyurethane flexible foam polyol and preparation method and application thereof |
| abstract | The invention discloses a vegetable oil polyurethane soft foam polyol, a preparation method and application thereof, wherein the method comprises the following steps: (1) carrying out ring-opening reaction on the epoxy vegetable oil, pyruvic acid, an alkaline catalyst and an inert solvent in a first microchannel reactor in a microchannel reaction device to obtain vegetable oil polyol; (2) and (2) carrying out addition polymerization reaction on the vegetable oil polyol obtained in the step (1), propylene oxide and an inert solvent in a second microchannel reactor in a microchannel reaction device to obtain the vegetable oil polyurethane flexible foam polyol. The vegetable oil polyurethane flexible foam polyol obtained by the invention has a novel structure, and can completely replace the traditional petrochemical polyol to be applied to the preparation of polyurethane foam materials. |
