Title: CALIXARENE-TYPE PHOTOCURABLE POLYURETHANE RESIN AND SELF-REPAIRING COATING PREPARED THEREFROM
Abstract:
Disclosed is a calixarene-type photocurable polyurethane resin, the calixarene-type photocurable polyurethane resin being prepared by means of the following steps: (1) preparing an isocyanate-terminated prepolymer; (2) preparing an isocyanate semi-terminated prepolymer; and (3) grafting the isocyanate semi-terminated prepolymer prepared in step (2) with a calixarene monomer to prepare the calixarene-type photocurable polyurethane resin. The present invention relates to grafting a calixarene with groups, such as photocurable coumarin and a double bond, to prepare a calixarene-type photocurable self-repairing polyurethane resin, thus greatly improving the hardness of self-repairing, while also ensuring a better self-repairing performance.
