| titleOfInvention | A kind of recovery method of polylactic acid waste |
| abstract | The present invention provides a kind of recovery methods of polylactic acid (PLA) waste, include the following steps, first dissolve by heating PLA waste in lactide, add after water reacted, obtain reaction mixture；Then after the product and calcium source hybrid reaction that above-mentioned steps are obtained, calcium lactate is obtained.Preparation process of the present invention dissolves PLA waste using high boiling lactide, makes the PLA of high molecular weight under conditions of not needing too high-temperature, it will be able to contact with water quick hydrolysis generation lactic acid occurs on a molecular scale, finally obtain lactic acid calcium product.Recovery method simple process provided by the invention, mild condition, high conversion rate do not use catalyst, can be reduced the discharge of waste, safety and environmental protection；And preparation method provided by the invention can also be recycled and be fed intake, and continuity is good, is more suitable for scale industrial production, has certain economic benefit and social benefit. |
