Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based fireproof and anticorrosion coating for steel structures and a preparation method thereof. Background technique [0002] Although steel structures are widely used in buildings due to their many advantages, the greatest weakness, which is extremely easy to conduct heat, will cause the steel structure to lose its bearing capacity in a fire, which will bring serious consequences. Therefore, it is very necessary to protect steel structures from fire. At present, fire-resistant coatings are the best material for fire protection of steel structures in engineering applications. [0003] Most of the current fire retardant coating products are solvent-based, which will produce a large amount of volatile organic compounds (VOC) during construction and use, which not only endangers people's life and health, but also pollutes the environment. The existing fireproo...
