Beschreibung
Zusammenfassung:	Disclosed in the present invention are a modified polyurethane material having excellent rain erosion resistance and weather resistance, a preparation method therefor, and the use thereof. The modified polyurethane composite material is prepared, by means of a prepolymer method, by adding a component A and a component B to a sealed container capable of being vacuumized and mixing and reacting same. The present invention uses hydroxyl-terminated liquid fluororubber and hydroxyl-terminated silane as modifying materials to introduce silicon-containing and fluorine-containing materials into polyurethane; a filler and a corresponding auxiliary agent are added and the filler forms physical crosslinking points so as to further adsorb the hydroxyl-terminated silicon/fluorine materials, thereby forming a homogeneous material. The present invention avoids the problem of poor homogeneity of obtained materials caused by layering phenomena occurring since organosilicon or organofluorine is migrated to the surfaces due to poor compatibility of the organosilicone or organofluorine with polyurethane, thereby preparing the modified polyurethane material having excellent rain erosion resistance and weather resistance.
