Problems solved by technology

Thin-coated steel structure fireproof paint can be divided into two types: solvent-based and water-based. Solvent-based fireproof paint uses a large amount of organic solvents in the production and construction process, which is harmful to the environment and construction personnel. Water-based fireproof paint is environmentally friendly and meets low pollution , the development direction of environmentally friendly coatings, but the research in our country started relatively late, and there is still a certain gap with solvent-based fireproof paints in terms of physical and chemical properties and weather resistance

Abstract

The invention discloses a fireproof paint prepared by the following raw materials by the weight: 25-45% of acrylic emulsion, 10-20% of dipentaerythritol, 5-15% of expanded graphite, 5-15% of melamine, 2-10% of ammonium polyphosphate, 3-10% of aluminium hydroxide, 2-5% of zinc oxide, 1-5% of silica, 4-10% of carbon fiber, 5-10% of silicon nitride fiber and the balance of water. The fireproof paint is the water paint; organic solvent is not needed in the preparation process; and the formula does not include halogen, so the fireproof paint does not release toxic or harmful gases containing the halogen, therefore, the fireproof pain has the advantages of security, low pollution and environmental protection, and is widely applied to various steel structure buildings.

Description

technical field [0001] The invention belongs to the field of building fire prevention, and in particular relates to a fireproof paint (coating). Background technique [0002] As a form of high-rise building structure, steel structure shows strong vitality in super high-rise and long-span buildings due to its high strength, light weight, good extensibility, earthquake resistance and short construction period. It is more and more widely used in the construction industry. However, the fire resistance of steel structure buildings is worse than that of traditional masonry structures and reinforced concrete structures. The mechanical strength of steel decreases rapidly with the increase of temperature, and quickly loses its supporting capacity, resulting in the collapse of buildings. Therefore, the protection of steel structures It must be done. Brushing or spraying fireproof paint (or fireproof paint) on the surface of steel structures is one of the commonly used protective met...
