Abstract

The invention discloses a high-fluidity high-impact-resistance polypropylene material which is prepared by mixing polypropylene, mixed high-density polyethylene, an elastic composite material, linear low-density polyethylene, a light stabilizer, food-grade white mineral oil, an antioxidant and an activating agent. The mixed high-density polyethylene component is added, so that the elongation at break of the prepared product is increased, high performance can be kept in a low-temperature environment, meanwhile, the low-temperature resistance of the product is improved by adding the linear low-density polyethylene, the low-temperature resistance is close to the low-temperature resistance, the fluidity is improved, and the elastic composite material is matched for mixing and toughening, so that the product can maintain high impact strength and elongation at break in a low-temperature environment, and the addition of the light stabilizer avoids rapid oxygenolysis of tertiary carbon atoms, so that the weather resistance of the product is improved.

Description

technical field [0001] The invention relates to the technical field of polypropylene materials, in particular to a high-fluidity high-impact polypropylene material.
