Leather surface coating, leather containing surface coating, preparation method of leather and luggage

The invention provides a leather surface coating, leather containing the leather surface coating, a preparation method of the leather surface coating and a luggage. The leather surface coating comprises a surface-enriched organic silicon modified polyether-polyurethane prepolymer, a liquid cross-linking agent and a coalescing agent, and the surface-enriched organic silicon modified polyether-polyurethane prepolymer contains a hydroxyl terminal or an amino terminal. And the surface enriched organosilicon modified polyether-polyurethane prepolymer, the liquid crosslinking agent and the coalescing agent do not contain an organic solvent. According to the leather surface coating, the surface-enriched organic silicon modified polyether-polyurethane prepolymer, the liquid cross-linking agent and the coalescing agent are compounded for use, and leather which does not contain VOCs, is greener and more environmentally friendly, suitable in hardness, high in compactness, excellent in three-proofing performance, good in
