Material for automobile exterior decoration and preparation method thereof

The invention provides a material for automobile exterior decoration and a preparation method thereof, and relates to the technical field of high polymer material processing assistants, the material for automobile exterior decoration comprises the following components by weight: 80-120 parts of polypropylene; 20 to 30 parts of polysulfone; 4 to 6 parts of a polypropylene-polysulfone compatilizer; 0.5 to 2 parts of rosin; 0.5 to 1 part of nano calcium carbonate; 0.5 to 1 part of nano titanium dioxide; 2-10 parts of ethylene propylene diene monomer; 1-3 parts of PP wax; the polypropylene-polysulfone compatilizer takes a polyether sulfone structure as a main chain and an aliphatic chain structure as a side group branch chain. According to the material for the automobile exterior decoration, the compatilizer for polypropylene-polysulfone is introduced, so that the wear resistance, heat resistance and mechanical properties are improved on the basis of reducing the deformation rate of the composite ...
