Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

Disclosed in the present invention are a colorful weather-resistant polypropylene composition and a preparation method therefor, which belong to the field of plastics. In the technical solution of the present invention, starting from an organic pigment per se in the components, a new composite coloring agent is obtained by wrapping the organic pigment with a modified resin of a specific proportion and a specific variety, and is then used for preparing the colorful weather-resistant polypropylene composition, such that not only the light stability of the organic pigment per se is effectively improved, but also a polypropylene matrix resin can be isolated to reduce the action between same and the organic pigment. The whole product can exhibit good weather resistance without specially adding extra ultraviolet light absorbers, light stabilizers, etc., such that the production cost is significantly reduced without weakening the basic mechanical properties of the product. Further disclosed in the present invention are a preparation method for the colorful weather-resistant polypropylene composition and the use thereof in the preparation of automobiles, electric tools or electrical products.
