description The invention discloses a low-shrinkage scratch-resistant high-gloss spraying-free polypropylene composite material and a preparation method thereof. The low-shrinkage scratch-resistant high-gloss polypropylene is prepared from the following raw materials in parts by weight: 65 to 85 parts of polypropylene resin, 8 to 15 parts of polystyrene, 4 to 7 parts of styrene-butadiene block copolymer, 5 to 8 parts of compatilizer, 5 to 10 parts of high-density polyethylene, 0.3 to 0.6 part of scratch-resistant agent, 0.4 to 0.8 part of auxiliary agent and 0.6 part of spraying-free effect powder. The shrinkage rate of the low-shrinkage scratch-resistant high-gloss polypropylene is 0.8-1.2, the surface gloss of the low-shrinkage scratch-resistant high-gloss polypropylene is 82-87, and the low-shrinkage scratch-resistant high-gloss polypropylene can meet the size requirements of polypropylene filled minerals and can endow materials with high gloss and scratch resistance. The material has wide application prospects in the
