The embodiment of the invention discloses a preparation method of an oxygen-enriched composite membrane, the oxygen-enriched composite membrane and application. A specific embodiment of the method comprises the following steps: 1, 1, 3, 3, 5, 5-hexamethyltrisiloxane and diallyl maleate are subjected to mixing treatment, and the mass ratio of the 1, 1, 3, 3, 5, 5-hexamethyltrisiloxane to the diallyl maleate is 1: (2-4); a first platinum catalyst is added, an intermediate product is obtained, and the side chain of the intermediate product contains vinyl; the second mixture, normal hexane and a second platinum catalyst are mixed, the second mixture is a mixture composed of an intermediate product and 1, 1, 3, 3-tetramethyldisiloxane, and the mass ratio of the intermediate product to the 1, 1, 3, 3-tetramethyldisiloxane is 1: (0.4-0.5); carrying out viscosity detection treatment on the polymer solution; and coating the polymer solution on the surface of the base membrane. According to the embodiment, the oxygen enrichment performance and the service life of the oxygen-enriched composite membrane can be improved.
