Title:
PREPARATION METHOD FOR ANTI-FOULING COATING CAPABLE OF CONTROLLED RELEASE OF ULTRAVIOLET-RESPONSIVE COUMARIN AND SELF-REPAIR
Document Type and Number:
WIPO Patent Application WO/2022/160853
Kind Code:
A1
Abstract:
A preparation method for an anti-fouling coating capable of the controlled release of ultraviolet-responsive coumarin and self-repair. The method comprises: reacting a double-end-group reactive polydimethylsiloxane, a polyisocyanate and an organic diluting solvent to obtain an isocyanate-terminated prepolymer; continuously adding a dihydroxy coumarin compound, a polyalcohol or polyamine cross-linking agent, and an organic tin catalyst, and reacting same to form a polymer solution of polyurethane; and continuously adding a simple coumarin compound, mixing same until uniform, and then irradiating same with 365 nm ultraviolet light to obtain the anti-fouling coating.
