Abstract

The invention discloses a graphene oxide modified polypropylene composite material and a preparation method thereof. The graphene oxide modified polypropylene composite material is prepared from, by weight, 100 parts of polypropylene, 5-6 parts of graphene oxide, 5-6 parts of calcium sulfate whiskers, 10-20 parts of styrene-butadiene segmented copolymer, 10-20 parts of ethylene-vinyl acetate copolymer, 0.1-0.3 part of divinyl benzene, 0.5-2 parts of benzoyl hydrazine, and 0.5-parts of a titanate coupling agent. The invention further discloses a preparation method of the graphene oxide modifiedpolypropylene composite material. The graphene oxide modified polypropylene composite material is high in crystallization rate, high in impact strength and good in toughness, so that the graphene oxide modified polypropylene composite material is particularly suitable for manufacturing various electric appliance shells requiring high strength.

Description

technical field [0001] The invention relates to a polypropylene composite material and a preparation method thereof, in particular to a graphene oxide modified polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is one of the most widely used general-purpose plastics in the world. It has the advantages of low density, good chemical corrosion resistance, insect resistance, low price, and excellent comprehensive physical and mechanical properties. However, the polypropylene currently on the market has high molding shrinkage, high brittleness, and low notched impact strength, especially at low temperatures, which greatly limits the further promotion and application of polypropylene. Therefore, the strengthening and toughening modification of PP has been extensively and deeply studied at home and abroad. But its performance still has room for improvement. Contents of the invention [0003] The technical problem...
