Abstract

The invention discloses a high-strength and low-VOC automotive interior polypropylene composite material. The composite material comprises the following components by mass: 80-100 parts of polypropylene resin; 10-20 parts of a toughening agent; 0.5-1 part of an antioxidant; 5-15 parts of diatomite; 0.5-1 part of a light stabilizer; 5-10 parts of a flame retardant; 15-25 parts of a reinforcing agent; and 10-20 parts of inorganic filler. The invention also discloses a preparation method of the polypropylene composite material, and the preparation method includes raw material mixing and extrusiongranulation. The polypropylene composite material prepared by the preparation method has low VOC and high strength, and has high commercial value and popularization value.
