The invention discloses aqueous fire-proof corrosion-proof paint for a steel structure and a preparation method thereof, and belongs to the technical field of paint. The aqueous fire-proof corrosion-proof paint comprises, by mass, 20-45% of a composite emulsion, 12-25% of a charring catalyst, 6-12% of a foaming agent, 8-17% of a charring agent, 5-10% of a fire retardant, 1-5% of layered double hydroxide, 8-18% of an corrosion-proof filling material, 4-12% of a strengthening filling material, 1-5% of modified nano-powder, 0.5-6% of an assistant and 10-30% of water. Through use of the composite modified emulsion as a base material, coating flame resistance, corrosion resistance and decorativeness are obtained and coating defects caused by a single emulsion as a base material are overcome. Through use of a small amount of the nano-powder, the coating is compact because of filling effects of the nano-powder, the coating corrosion caused by O2, H2O and Cl <-> is avoided, good fire-proof and corrosion-proof effects are obtained under the condition of a small addition amount and a cost is reduced. The aqueous fire-proof corrosion-proof paint has the characteristics of green environmental protection and simple preparation processes.

Composite polystyrene heat insulation material and preparation method of heat insulation board

The invention discloses a fireproof and flame-retardant composite polystyrene heat insulation material and a method for preparing a heat insulation board by using the material, which belongs to the technical field of the heat insulation boards. The composite heat insulation board combining an inorganic heat insulation material and an organic heat insulation material has the characteristics of fireproof property, heat insulation, flame-retardant property and low heat conductivity of the organic material, so the fireproof and flame-retardant performance of the composite heat insulation material can be improved based on unchanging the heat conductivity of the polystyrene. The method for preparing the composite heat insulation board is simple and easy to operate; each polystyrene granule is covered with a layer of a fireproof and flame-retardant material on the surface, so that each granule forms an integrated and independent unit, thereby effectively interrupting the conduction of the heat and the spread of the flame to achieve a non-combustion effect. The prepared composite polystyrene heat insulation board has the advantages of light weight, low heat conductivity, good heat insulation effect, high tensile strength, good toughness, high size stability, low moisture absorption and good flame resistance, and the combustion performance can be A2 grade (GB8624-2006).
