Problems solved by technology

The reason for the unsatisfactory fireproof performance of the fireproof coating prepared by the above emulsion is that the decomposition temperature of the emulsion resin and ammonium polyphosphate and other flame retardant powders does not match ideally, and the viscosity of the resin after melting is relatively large, which limits the expansion process of the foamed carbon layer. , the expansion ratio of the carbon layer is low, which leads to a t

Embodiment 1

[0021] A preparation method of a water-based ultra-thin steel structure fireproof coating has the following steps:

[0022] (1) According to the mass percent of each component: 22.5% of tertiary vinegar emulsion, 2.4% of chlorinated paraffin, 21.8% of ammonium polyphosphate, 7.8% of monopentaerythritol, 13.7% of melamine, 0.3% of defoamer, 0.3% of dispersant, 0.4% thickening agent, 0.2% chelating agent, 0.2% pH regulator, 0.8% film-forming aid, 0.05% preservative in tank, 0.5% antifungal agent for paint film, 6.6% titanium dioxide, and the balance is water. Prepare materials ; First, crush the monopentaerythritol through a powder crusher to crush the hard crystals into powder, so as to reduce the subsequent sanding time and improve production efficiency;

[0023] (2) Dispersant, thickener, half of defoamer, paint film antifungal agent, preservative in tank, half of pH regulator, chelating agent, ammonium polyphosphate, melamine, powdered monopentaerythritol, Titanium dioxide ...

Abstract

The invention relates to the field of preparation technologies of functional coatings, in particular to an aqueous ultrathin steel structure fire-retardant coating and a preparation method thereof. The coating comprises a vac-veova emulsion, chlorinated paraffin, ammonium polyphosphate, mono-pentaerythritol, melamine, a defoaming agent, a dispersant, a thickening agent, a chelating agent, a pH regulating agent, a film forming aid, a tank preservative, a paint film mold inhibitor, titanium pigment and water. In the aqueous ultrathin steel structure fire-retardant coating disclosed by the invention, the film forming agent with low glass transition temperature and flame retardant series and aid series with high mutual matching properties are adopted, so that the obtained fire-retardant coating has the excellent characteristics of high thixotropic property, good 'tank opening effect', high foaming performance and high flame retardance; and the preparation method of the fire-retardant coating has the advantages of readily-available raw materials, simple steps, low cost, convenience, environmental friendliness and high construction property.

Description

technical field [0001] The invention relates to the technical field of preparation of functional coatings, in particular to a water-based ultra-thin fireproof coating for steel structures and a preparation method thereof. Background technique [0002] With the continuous development of my country's economy and the gradual increase in steel production, steel structure buildings continue to emerge, especially the development of light steel structures is in full swing. The application range of steel structures has expanded from industrial and large-scale public facilities construction to civil buildings, etc. However, although the steel structure has the advantages of high strength and good processing performance, its poor fire resistance is also an unavoidable problem. Brushing fireproof coatings on the surface of steel structures is a common method in the fire protection of steel structures at present. A water-based ultra-thin fireproof coating for steel structures in the prio...
