Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a high-strength and high-toughness flame-retardant polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) resin is a thermoplastic material obtained by polymerizing propylene. It has excellent comprehensive performance and relatively low price. It is widely used in home appliances, automobiles, electrical and electronics and other fields. However, the existing polypropylene materials generally have the defects of poor flame retardancy, strength and toughness to be further improved. It is in this situation that polypropylene composite materials came into being. [0003] Polypropylene composite materials are made by compounding polypropylene resin with other fillers and functional additives by means of blending and filling. This type of material can effectively improve the flame retardancy, strength and toug...
