Abstract

The invention belongs to the technical field of 3D printing, and discloses a polypropylene composite material and a preparation method and application thereof. The polypropylene composite material comprises, by weight, 25-70 parts of homopolymer polypropylene, 10-40 parts of copolymerized polypropylene, 5-10 parts of polylactic resin, 10-20 parts of inorganic fillers, 2-5 parts of a compatibilizerand 0.1-5 parts of an auxiliary. According to the polypropylene composite material, a prepared product has the advantages of uniform wire diameter, higher cross section roundness, good processing fluidity, excellent mechanical performance and lower shrinkage rate, the polypropylene composite material can be applied to the fields of 3D printing consumable materials, and the technical defects of easy upward tilting and deformation, nonuniform 3D printing consumable material wire diameter, the failure of being round in cross section and the like in 3D printing process in the prior art are overcome to further promote the development of the polypropylene material in the field of 3D printing materials.
