Polypropylene composite material as well as preparation method and application thereof

The invention discloses a polypropylene composite material for a car seamless dashboard. The polypropylene composite material consists of the following raw materials in percentage by weight: 50-70% of propylene-ethylene block co-polypropylene, 3-10% of polyethylene, 5-30% of a thermoplastic elastomer, 5-30% of talcum powder, 0.5-3% of a composite photo-thermal stabilizing agent, 0.1-1% of a lubricating agent, 0.5-4% of anti-scratch additives and 0-5% of a coloring agent. The polypropylene composite material for the car seamless dashboard can show excellent low-temperature impact resistance, particularly, can be used for meeting the multi-axial low temperature impact performance of fracture toughness at -35 DEG C, also has the characteristics such as scratch resistance, weather resistance and low total carbon, and can be used for meeting the requirements of a high-grade car seamless blasting dashboard. The invention also discloses a preparation method of the polypropylene composite material. The preparation method is simple to operate, does not need special equipment, is low in cost, and is suitable for industrial production.
