Abstract

The invention relates to an ultra-thin steel structure fire-resistant coating material with a multi-core structure. The ultra-thin steel structure fire-resistant coating material is characterized by comprising three parts, i.e. an expandable fire-resistant antirust priming coat at high temperature, an expandable fire-resistant intermediate coat when contacted to fire and a fire-resistant finishing coat. In actual construction, at least one layer of fire-resistant antirust priming coat with a high-temperature expanding function, at least one layer of intermediate coat with an expanding function when contacted to fire and at least one layer of decorative finishing coat with flame retarding and smokeless performance are coated; the priming coat, the intermediate coat and the finishing coat are formed by compounding organic and inorganic materials; when a fire occurs, the intermediate coat and the finishing coat exert synergistic reaction, and thus, an effect that the priming coat carries out fire resisting and heat insulation and the finishing coat carries out inflame retarding and smoke purifying, is achieved. With the adoption of the ultra-thin steel structure fire-resistant coating material with the multi-core structure, provided by the invention, a fire-resistant coating with thinner coating thickness, longer fireproofing time limit and better decorative effect can be formed on a steel structure, and proved by experiments, the fireproofing standards of GB14907-2002 are fully met.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to an ultra-thin steel structure fire-resistant coating with a multi-core structure. Background technique [0002] With the gradual increase of steel structure buildings and components in my country and the further implementation of the "Fire Protection Law of the People's Republic of China", fire-resistant coatings for steel structures have been more and more widely used. According to the classification of GB 14907-2002 "General Technical Conditions for Fireproof Coatings for Steel Structures", even the ultra-thin fireproof coatings for steel structures must have a coating thickness of 2mm. According to the calculation of existing high-solid coatings, the construction must also be painted It takes 8-10 times to reach the specified thickness, which brings considerable difficulty to the construction and affects the construction speed of the building. At the same time, today's...
