Problems solved by technology

However, two important problems arise: (1) poor dispersion of graphite-phase carbon nitride in polystyrene; (2) low flame-retardant efficiency of graphite-phase carbon nitride, making it difficult to make flame-retardant PS composites suitable for practical applications
Moreover, the heat released in it will accelerate the decomposition of hypophosphite, causing more damage

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an impact-resistant phosphorus-rich hybrid polystyrene composite material and a preparation method thereof. Background technique [0002] As a general-purpose thermoplastic material for large-scale applications, polystyrene is widely used in automobiles, construction, electronic appliances and other fields due to its excellent heat resistance, low density, mechanical durability and processing properties. However, PS is a highly flammable material, and its combustion characteristics are closely related to its pyrolysis behavior, the types of released gas products, and their chemical composition during thermal degradation. In addition, its combustion will not only produce severe molten dripping but also release a large amount of toxic fumes, resulting in heavy casualties and property damage. Studies have shown that graphite-like graphitic carbon nitride as a two-dimens...
