The invention discloses a preparation method of an ultra-low VOC (volatile organic compound) polypropylene-based automobile special material, relates to the technical field of preparation of automobile special materials, and mainly solves the problem of air pollution sources of automobile interiors. The preparation method of the ultra-low VOC polypropylene-based automobile special material comprises the following steps: (1) preparing graphite oxide; (2) preparing an MIL-101 (at) GO composite material; and (3) preparing the polypropylene-based automobile special material by taking recycled polypropylene as a basis and combining the MIL-101-coated GO composite material, superfine slag powder, a heat stabilizer and an elastomer. According to the technical scheme, the release amount of VOC is greatly reduced from the source, the purpose of ultralow VOC release of the special material for the automobile is achieved, and a good solution is provided for the air pollution problem of the automotive trim from the sourc
