Polyurethanes with double bonds were prepared by hydroxy fluorosilicone oil, Pentaerythritol triacrylate(PETA) as a raw material. The ultraviolet absorbers(UVA400) and nanosilica particles were added to the finishing solution to improve the UV protection and surface roughness of the coating. The ultraviolet(UV) blocking and superhydrophobicity fabric coating was fabricated by UV light initiate double bond radical polymerization. FTIR and SEM analysis show that fluorosilanes and PETA are introduced into the polyurethane molecular chain. The surface of the fabric has micro-nano-shaped projections, and the rough surface coating was constructed. Hydrophobic and UV protective tests of coated fabrics show that the coated fabric with excellent superhydrophobicity and UV protection performance when w(silicon dioxide)=15.0% and w(UVA400)=1.5%, the coated fabric has a water contact angle of 154°, roll angle of 9°, ultraviolet protection factor(UPF) value of 72, and transmittance of ultraviolet A(UV-A)band was 2.96%. And the coated fabric after accelerated aging test 120h, the contact angles was 155°, the UPF values was 117, the transmittance of the UV-A band was 2.68%, respectively, and with excellent durability.
