The invention discloses a chemical-resistant polypropylene composite material and a preparation method thereof. The composite material is prepared from the following components in parts by weight: 74-90.8 parts of polypropylene, 3-10 parts of MoO3 microspheres, 5-10 parts of a flexibilizer, 0.5-2 parts of an antioxidant, 0.5-2 parts of a light stabilizer and 0.2-2 parts of a lubricant. The prepared MoO3 microspheres are of a microsphere structure constructed by hollow nanorods, are of a porous structure with a large specific surface area, and are preferentially dispersed in an amorphous area of polypropylene in a polypropylene composite material. When an external chemical is immersed into polypropylene under the action of a capillary tube, the chemical is firstly immersed into an amorphous area of the polypropylene, and due to the existence of the MoO3 microspheres, the chemical is absorbed by the hollow structures of the MoO3 microspheres and is embedded in the microspheres, so that the MoO3 microspheres hav
