The invention discloses a polypropylene composite material as well as a preparation method and application thereof, and relates to the technical field of high polymer materials. The invention provides a polypropylene composite material. The polypropylene composite material comprises the following components in parts by weight: 65-85 parts of PP resin, 5-10 parts of PET resin, 3-8 parts of an ethylene-acrylic acid copolymer and 3-8 parts of tackifying resin. The EAA and the tackifying resin are matched, so that the compatibility of the PP resin and the PET resin is remarkably improved, the mechanical properties such as weld mark strength of the polypropylene composite material are improved, and the stability of the polypropylene composite material is further improved.
