The composite material is prepared from the following raw materials in parts by weight: 10 to 14 parts of graphite phase carbon nitride, 3 to 4 parts of hypophosphorous monohydrate, 1 to 2 parts of paraformaldehyde, 0.8 to 1 part of triethylamine, 3 to 5 parts of phenyl dichlorophosphate, 1 to 2 parts of aluminum sulfate octadecahydrate, 2 to 3 parts of 0.1 to 0.2 mol / l hydrochloric acid, 100 to 110 parts of polystyrene, a proper amount of acetonitrile, a proper amount of deionized water, a proper amount of absolute ethyl alcohol, 3 to 4 parts of allyl polyethylene glycol, 4.6 to 5 parts of sodium myrastate, 1 to 2 parts of nickel aminosulfonate, 3 to 5 parts of triethyl acetyl citrate, 0.4 to 1 part of calcium lactobionate, 2 to 3 parts of magnesium stearate, 0.3 to 1 part of hexamethyl phosphoric triamide, 0.3 to 1 part of trimethylol propane, 2 to 3 parts of hydrolytic polymaleic anhydride, and a proper amount of absolute ethyl alcohol and acetonitrile. The composite material does not contain toxic and harmful volatile substance, and is high in surface strength, good in safety and environmental protection property and excellent in comprehensive performances.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an environment-friendly 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-di...

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
