Abstract

The invention discloses a light high specific strength modified polypropylene material and a preparation method thereof. The light high specific strength modified polypropylene material is prepared from the following components in percentage by mass through mixing: 48-75% of polypropylene, 10-25% of a toughening agent, 4-20% of light powder packing, 6-15% of chopped glass fiber, 2-10% of a compatilizer, 1-3% of a lubricant, 0.5-3% of a coupling agent and 0.4-1% of an antioxidant. As hollow inorganic powder packing is adopted as a packing material and the chopped glass fiber as a reinforcing material, the synergistic effect of the two components is brought into sufficient play, and reasonable modification processes and preparation methods are used, the completeness of a particle structure of hollow inorganic powder is ensured while the binding strength of the hollow inorganic powder with resin is improved, and thus the material has both excellent properties of low density and high strength finally. The light high specific strength modified polypropylene material disclosed by the invention can meet most plastic property requirements of manufacturing fields such as automobiles, domestic electric appliances, rail transit, aerospace, ships and submarines, and the field of modern sponge city construction, and development with energy conservation and emission reduction and low carbon and environment protection of the fields can be promoted.
