| titleOfInvention | Ultraviolet light excited color changing/heating composite color polyurethane and synthesis method thereof |
| abstract | The invention discloses ultraviolet light excited color changing/heating composite color polyurethane and a synthesis method thereof, belonging to the technical field of chemical synthesis. The synthesis method comprises the steps of uniformly mixing the fluorescein, the alkyl diamine compound and the solvent, heating and reacting under mechanical stirring, drying the product after the reaction is finished, and purifying the product through chromatography to obtain the fluorescein derivative; dissolving diisocyanate and polydiol in a solvent, heating and reacting for a period of time under mechanical stirring, then adding a chain extender and slowly dropwise adding dibutyltin dilaurate to continue reacting, then adding a fluorescent yellow derivative into the reactant, continuing heating and reacting, soaking and washing with the solvent after the reaction is finished to remove monomers which do not participate in the reaction, and then drying the reactant to obtain the final product. The target product ultraviolet light excited color changing/heating compound color polyurethane has important application value in the fields of military affairs, anti-counterfeiting, encryption, clothing, medicine and the like. |
