| titleOfInvention | Preparation method of visible light cured self-repairing fluorine-containing polyurethane resin |
| abstract | The invention belongs to the field of photocuring bio-based intelligent materials, and particularly relates to a preparation method of visible light-cured self-repairing fluorine-containing polyurethane resin. Firstly, dichloromethane, a double-active functional group photoinitiator, a weak alkaline acid-binding agent and trifluoroacetyl chloride are reacted in a nitrogen protection device to prepare a fluorine-containing photoinitiator; performing double carboxylation treatment on the tung oil acid which is a hydrolysate of the triglyceride of the tung oil acid, and finally preparing the self-repairing fluorine-containing polyurethane resin cured under the visible light condition under the synergistic action of a dihydroxyl fluorine-containing monomer, a fluorine-containing photoinitiator and diisocyanate. The polyurethane resin overcomes the defects of high brittleness, easy breakage and poor high temperature resistance of the traditional light-cured resin, is cured by utilizing visible light which is friendly to human bodies, has a self-repairing function, can prolong the service life of the material, enhances the weather resistance and the high temperature resistance, and has renewable monomer sources and good application prospect. |
