The invention discloses a polypropylene composition as well as a preparation method and application thereof, and belongs to the technical field of high polymer materials, the polypropylene composition comprises the following components in parts by weight: 42-82 parts of polypropylene resin, 4-42 parts of styrene elastomer, 4-21 parts of compatilizer, 4-21 parts of glass fiber and 0.08-1.1 parts of nucleating agent; the nucleating agent comprises at least one of an alpha crystal form nucleating agent and a beta crystal form nucleating agent. The polypropylene resin is used as a matrix, under the combined action of the styrene elastomer, the compatilizer, the glass fiber and the nucleating agent, the tensile strength, the welding tensile strength and the light transmittance of the polypropylene composition are effectively improved, so that the polypropylene composition has a wider welding wave band, and the polypropylene composition is very suitable for preparing automobile parts, such as automobile parts and automobile parts. The method is especially suitable for preparing automobile bumpers.
