| titleOfInvention | A kind of technique for preparing polyurethane foam using the new liquifying method of lignin |
| abstract | The invention discloses a kind of technique that polyurethane foam is prepared using the new liquifying method of lignin, it comprises the following steps：(1) lignin, liquefied reagent, catalyst and surfactant are well mixed, 130~180 DEG C, 30~120min is reacted under stirring condition, after reaction terminates, natural cooling, obtain liquefying lignin polyalcohol；(2) mixing of liquefying lignin polyalcohol and PPG made from step (1) is taken, lignin-base polyurethane foam is prepared according still further to the foam process of polyurethane foam processed.The inventive method efficiency high, lignin-base polyalcohol after liquefaction degraded contains higher hydroxy radical content and reactivity is higher, substantially increase the compatibility of lignin and organic solvent polyalcohol, with good dispersiveness, safe and non-toxic, green environmental protection degradable polyurethane foamed material can be prepared. |
