The invention discloses a low VOC polypropylene composite material and a preparation method and an application thereof. The material is prepared by polypropylene, a filling agent, a smell removing agent, a scraping-proof agent, an antioxygen, a weather-proof agent and a lubricating agent according to part by weight, wherein the smell removing agent is a water-based solution of a polymer surfactant which is adsorbed on a polypropylene carrier; the used smell removing agent is a novel smell removing agent, the melting point of the smell removing agent is 160 DEG C, the boiling point is higher than 100 DEG C; the smell removing agent has the characteristic that the dispersion is uniform, lots of foam of the fused smell removing agent is generated in an extrusion mixing process, the vacuum devolatilization is clean, residue is not generated and the like. The prepared low VOC polypropylene composite material has the characteristics of being UV resistant, scraping resistant, light in smell, less in the VOC residual volume and the like, and is mainly used on automotive trim materials such as an instrument desk, a door plate and a stand column of an automobile.
