摘要（英）：

The invention relates to the technical field of plastic modification, and especially relates to a PP composite material special for high-performance automobile instrument boards and a preparation method thereof. The PP composite material is composed of the following compositions in parts by mass: 15-25 parts of homopolymerized PP, 30-50 parts of copolymerized PP, 15-25 parts of talcum powder, 12-20 parts of a flexibilizer and 0.3-0.6 part of a coupling agent, 0.3-0.5 part of an anti-oxidant, 0.1-0.3 part of a weather resistant agent and 0.3-0.5 part of a lubricant. The preparation method of the PP composite material comprises mixing, extrusion and injection moulding. The PP composite material provided by the invention has relatively high bursting resistant strength, is capable of satisfying the usage requirements of middle/high sedans and is suitable for being used as a material special for the high-performance automobile instrument boards.
