In this paper,the wear-resistant polyurethane resin was prepared by fluorine-containing silane modification.The uhraviolet aging resistance and anti-fouling performance of the resin were greatly improved by introducing fluorine element.The effect of fluorine content on the wear resistance,UV resistance and anti-fouling properties of the coating was investigated.The results showed that when the fluorine content reached a certain amount in the total resin system,the resin coating had both good wear-resistance and UV aging resistance and anti-fouling performance,the overall performance was the best.
