Abstract

The invention discloses waterborne fireproof coating for a steel structure and a preparation method of the waterborne fireproof coating. The waterborne fireproof coating is mainly prepared from, by weight, 15-23 parts of ammonium polyphosphate, 11-13 parts of melamine, 6-12 parts of pentaerythritol, 7-13 parts of waterborne epoxy resin, 11-15 parts of hydroxyl acrylic acid emulsion, 6-10 parts of phenolic resin, 2-6 parts of montmorillonite, 19-25 parts of deionized water, 1.0-1.8 parts of thickener, 2-4 parts of dispersion agent and 0.14-0.22 part of defoaming agent. The waterborne fireproof coating is long in flame retardance time, high in adhesive strength, less prone to seasoning crack, excellent in fire resistance, nontoxic, safe, environmental friendly, and the like.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a water-based fireproof coating for steel structures and a preparation method thereof. Background technique [0002] With the continuous development of my country's society and economy, the losses caused by fires are also increasing. In order to reduce the loss caused by fire, it is necessary to strengthen the construction of fire protection products. As an important member of fire protection products, fire retardant coatings play an extremely important role in it. With the enhancement of people's awareness of environmental protection, more and more attention is paid to water-based fire retardant coatings. Water-based fire retardant coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. Its flame retar...
