Easy-to-mold high-impact-resistant spraying-free polypropylene material and preparation method thereof

The invention discloses an easy-to-mold high-impact-resistant spraying-free polypropylene material. The formula comprises the following components by weight: 60-70 parts of polypropylene, 15-25 partsof superfine activated talcum powder, 2-4 parts of silicon-based aluminum powder master batch, 1-2 parts of glass-based pearl powder, 1-2 parts of a hyperbranched flowing agent, 2-4 parts of siliconemaster batch, 4-6 parts of a compatilizer, 0.5 part of an antioxidant and 0.5 part of an anti-ultraviolet additive. According to the invention, the defects in the prior art are overcome, the materialof a traditional paint spraying piece is replaced, the injection molding defects of weld lines, crazes and the like in the production process of the spraying-free material can be solved, and good impact performance can be maintained and the rejection rate is reduced on the basis of ensuring good flowability, so that the cost is greatly saved, and the production benefit is improved. 本发明公开了一种易成型高抗冲免喷涂聚丙烯材料，按重量份重量计，其配方如下：聚丙烯:6
