Waterborne intumescent flame-retardant coating and preparation method thereof

Abstract

The invention provides waterborne intumescent flame-retardant coating. The waterborne intumescent flame-retardant coating comprises, by weight percentage, 20-30% of waterborne flame-retardant emulsion, 5-10% of waterborne composite nano flame-retardant dispersion slurry, 20-30% of acid source, 1-3% of carbon source agent, 8-15% of waterborne flame-retardant foaming agent, 0.5-1% of toughening agent, 5-10% of lead-free filler, 1-3% of waterborne wetting dispersing agent, 0.2-1% of penetrating agent, 0.5-1% of solubilizing stabilizer, 0.5-2% of anti-fouling agent, 0.5-2% of amine neutralizer, 0.5-2% of anti-freezing agent, 0.5-2% of coalescing agent and 8-15% of deionized water. The waterborne intumescent flame-retardant coating has the advantages that the complementary advantages of the materials are utilized sufficiently, and flame-retardant ultimate strength of base materials such as steel structures and decoration materials after the base materials such as the building steel structures are coated with the coating.

Description

Technical field [0001] The invention relates to the technical field of water-based fireproof materials, in particular to a water-based swelling fireproof coating and a preparation method thereof. Background technique [0002] With the development of construction, transportation, petrochemical, electric power and other industries, infrastructure materials are constantly being updated. Steel structures are comprehensive due to their high strength, light weight, flexible structure, short construction period, good seismic performance, and recyclability. Advantages, it has become the main structural form of large space buildings and has been widely used in construction. [0003] At the same time, with the rapid development of the application field of steel structure buildings, the problem of steel structure protection technology has become more prominent. Although the steel structure material itself is a non-combustible material, the steel structure has a fatal weakness of poor h...

AI Technical Summary

Problems solved by technology

Due to the long-term outdoor harsh environment of the steel structure, the protective performance of certain varieties of fire-resistant coatings is not ideal, and it is difficult to protect the base material, resulting in a large amount of metals that need to be re-smelted, equipment and components replaced, resulting in a serious waste of resources and energy, and even lead to Disasters and accidents cause direct economic losses, etc. But these shortcomings will be overcome through practice to meet the needs of fire prevention
