The invention discloses a polyurethane thermal insulation material of a solar energy water tank. The polyurethane thermal insulation material of the solar energy water tank comprises an aqueous polyurethane coating and polyurethane plates; the aqueous polyurethane coating is composed of a dispersing agent and a reacted prepolymer; the prepolymer is composed of aminopropyltriethoxysilane, hexamethylene diisocyanate, alkyl cyclodextrin and tripropyl borate (2, 3-dibromide), and the mass ratio of aminopropyltriethoxysilane to hexamethylene diisocyanate to alkyl cyclodextrin is 1:3:2; and the twopolyurethane plates are arranged in parallel, a hollow layer is reserved in the middle of the two polyurethane plates, distilled water is injected into the hollow layer, sealing treatment is performedall around, and a layer of aqueous polyurethane coating is applied to the upper layer of the polyurethane plates. The polyurethane thermal insulation material of the solar energy water tank has inflaming retarding and smoke p
