Step 4：Take polystyrene/SiO of 90-100 parts by weight2Nucleocapsid composite particles, carried out by the way that 0.4MPa vapor is heated Prefoam, operating time 40s, then the particle of prefoam is cured, it is small to place it in natural drying curing 24 in room temperature When, obtain prefoam curing particle；
Step 5：Weigh the phenolic resin of 80-90 parts by weight, the expansion-type N-P flame-retarding agent of 4-5 parts by weight and 1-2 parts by weight Neopelex, be well mixed, 5min, mixing speed 45r/min are stirred in electric blender, be made it is fire-retardant Covering liquid；
Step 6：Fire-retardant covering liquid is mixed with prefoam curing particle, the high-speed stirred 5min in electric blender, stirring speed Spend for 700r/min, fire-retardant covering liquid is uniformly coated on prefoam curing particle surface, and add consolidating for 15-20 parts by weight Agent continues after stirring 3min, obtains fire-retardant coated particle；
Step 7：Fire-retardant coated particle is poured into mould, mould is placed on compression molding in vulcanizing press, compression molding Machine upper and lower plates temperature control is at 102-106 DEG C, briquetting pressure 7.5MPa, time 3min.
A kind of 7. preparation method of polystyrene flame-proof environmental protection foamed material according to claim 6, it is characterised in that：Institute The SiO stated2Aeroge particle diameter is 0.225 μm, hole ratio 90%-99.8%, specific surface area 800m2/g-1000m2/g。
