Abstract

The invention discloses a corrosion-resistant water-based ultrathin fireproof coating for a steel structure and a preparation method thereof. The corrosion-resistant water-based ultrathin fireproof coating is prepared from, by weight parts, 5-10 parts of styrene-acrylic emulsion, 10-25 parts of acrylic acid emulsion, 10-15 parts of polyborosiloxane flame retardant, 30-55 parts of intumescent flame retardant, 3-5 parts of preservative, 1-3 parts of auxiliaries and 15-30 parts of water. The corrosion-resistant water-based ultrathin fireproof coating for the steel structure is good in weather resistance and aging resistance, excellent in corrosion resistance, high in force of adhesion to steel and good in caking property and has effects of long-acting fire prevention, long-term weather resistance and aging resistance.

Description

technical field [0001] The invention relates to a coating, in particular to a corrosion-resistant water-based ultra-thin steel structure fireproof coating. Background technique [0002] Fireproof coating refers to a type of coating that is applied on the surface of objects to prevent fire, prevent the spread of fire or isolate the source of fire, prolong the ignition time of the substrate or increase the thermal insulation performance to delay the structural damage time, according to the purpose and the object of use. It can be divided into: decorative fireproof coatings, cable fireproof coatings, steel structure fireproof coatings, prestressed concrete floor fireproof coatings, etc. [0003] Among them, water-based ultra-thin steel structure fireproof coating is a new type of water-based fireproof coating, which is painted on the surface of steel components in buildings and structures, and the coating thickness does not exceed 3mm. When encountering fire, the paint expands...
