Abstract

The invention discloses an ultra-thin fireproof coating for a steel structure and a preparation method thereof. The coating has the characteristics of high gloss, good water resistance, strong adhesion force and so on of a solvent based ultra-thin fireproof coating, also has the advantages of water-based coatings by taking water as a medium, and satisfies the direction of developing low-pollution and environment-friendly coatings of the coating industry. The technical proposal comprises that the ultra-thin fireproof coating for the steel structure is prepared from the following components by weight portion: 10 to 35 portions of acrylic hybrid emulsion, 10 to 25 portions of dehydration and carbon-forming catalyst, 10 to 25 portions of carbon forming agent, 5 to 20 portions of foaming agent, 5 to 20 portions of flame retardant, 5 to 25 portions of pigment and filler, 3 to 10 portions of reinforcing agent, 5 to 10 portions of latent solvent, 1 to 5 portions of dispersant, 0.1 to 1 portion of foam killer, 0.2 to 2 portions of flatting agent, 0.2 to 2 portions of thickening agent, 1 to 5 portions of film forming additive, and the balance being water.

Description

technical field [0001] The invention relates to a building fireproof coating, in particular to an ultra-thin steel structure fireproof coating and a preparation method thereof. Background technique [0002] With the development of the economy, new buildings are constantly emerging. Compared with the traditional wood structure, masonry structure and reinforced concrete structure, the steel structure has high strength, strong load capacity, light weight, small space occupation, and component manufacturing. With many advantages such as convenient installation and saving wood, it is more and more widely used in construction. However, the fire resistance of steel structure buildings is poor compared with masonry structures and reinforced concrete structures. Therefore, it is necessary to protect the steel structure from fire, and the use of fire-resistant coatings is an ideal protection method. The steel structure fire retardant coating is sprayed on the surface of steel compon...
