Automotive polypropylene interior material and preparation method thereof

The invention relates to the technical field of high polymer materials, in particular to an automotive polypropylene interior material and a preparation method thereof. The automotive polypropylene interior material comprises the following components in percentage by weight: 63%-69% of co-polypropylene, 20% of talcum powder, 10% of a flexibilizer, 0.4% of an antioxidant, 0.4% of a lubricant, 0.2% of a light stabilizer, 0%-3% of a deodorant and 0%-3% of a low surface temperature agent. The automotive polypropylene interior material provided by the invention adopts the deodorant containing a microporous water-containing structure to reduce the odor grade of the material, can meet the requirements of material outlines of various main engine plants, adopts the GATO powder (cesium-tungsten nano oxide powder) to reduce the surface temperature of internal parts of an automobile, and has the characteristics of good weather resistance and good weather resistance after the automobile is exposed to the sun in summer.
