Abstract

The invention relates to an aqueous ultra-thin expansion type steel structure fire-proof anti-corrosive paint and a preparation method thereof. The fire-proof anti-corrosive paint is prepared by adding ammonium polyphosphate, pentaerythritol, melamine, titanium white, expandable graphite, a preservative, a ceramic filler, an antifoaming agent, a dispersing agent, a plasticizer and the like into organic silicon-modified acrylic resin emulsion serving as a film forming base material. The paint has the advantages of high fire-proof performance, anti-corrosion and anti-rust function, and high water resistance, acid-alkali resistance and corrosion resistance, capability of meeting the requirements of various steel structures on the fire-proof and anti-corrosion performance, environmental friendliness, low cost, and readily available raw materials, so the paint can be widely applied to fire-proof protection of various steel structures.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to ultra-thin intumescent fireproof coatings for building steel structures. Background technique [0002] Steel structures have the advantages of light weight, high strength, and convenient construction, and are increasingly widely used in large buildings. However, the fire resistance of steel structures is very poor and it is easy to conduct heat. When its temperature exceeds 540°C, its mechanical strength is almost completely lost. At this time, the building will be unable to support its own mass and collapse, causing huge losses to people's lives and property. Therefore, it is necessary to provide fire protection for steel structure buildings through fire protection. Among the many steel structure fire protection measures, coating the steel surface with fire retardant coating is the simplest and most effective way. [0003] There are many types of fire retardant coatings for s...
