description The invention discloses a preparation method of chlorinated polypropylene and belongs to the technical field of polypropylene chlorination preparation. A water-phase suspension method chlorination process belongs to heterogeneous chlorination, polypropylene is non-uniform in chlorination, and chlorinated polypropylene is poor in solubility. The preparation method of the polypropylene powder comprises the following steps: uniformly mixing a polypropylene resin raw material with a degradation initiator and a homogenizing agent, extruding and granulating, and grinding into powder by a liquid nitrogen grinding machine, so as to obtain the polypropylene powder, wherein the degradation initiator is a mixture of one or more of aromatic peroxide, aliphatic peroxide and cyclic ketone peroxide in any proportion; the homogenizing agent is a mixture of one or more of mineral oil, cyclohexanone, chlorinated hydrocarbon and the like in any proportion. The degradation initiator is matched with the homogenizing agent, so tha
