Abstract

The invention discloses a waterborne ultrathin steel structure fireproof coating material, prepared from the following components in percentage by weight: 17 to 23.5 percent of vac-veova emulsion, 18 to 25 percent of MF resin modified ammonium polyphosphate, 7 to 12 percent of tripolycyanamide, 7.5 to 12.5 percent of pentaerythritol, 0.8 to 1.5 percent of coalescing agent, 0.20 to 0.50 percent of defoamer, 0.30 to 0.60 percent of dispersant, 0.10 to 0.30 percent of preservative, 0.2 to 0.8 percent of thickener, 4 to 8 percent of titanium dioxide, 2 to 6 percent of inorganic filler, 0.15 to 0.30 percent of pH regulator and the balance of water. The coating material is proper in fire resistance, and has outstanding water resistance and good cracking resistance; a prepared coating layer is stable in physical and mechanical properties, outstanding in cracking resistance and water resistance and excellent in fire resistance, and when the coating layer thickness is 1.8mm, the fire-resistant time is 90min or longer.

Description

technical field

[0001] The invention relates to the technical field of water-based coatings, in particular to a water-based ultra-thin fireproof coating for steel structures and a preparation method thereof. Background technique

[0002] As the main form of modern architecture, steel structure has been widely used because of its light weight, high strength, good seismic performance, short construction period, high degree of industrialization of buildings, large space utilization rate, and investment saving. It is widely used in airports, stations, It is widely used in production plants, bridges, exhibition venues, stadiums, large shopping malls, high-end hotels, offshore platforms, hydraulic engineering, petrochemical and other buildings. In seismically active areas or surrounding areas after earthquakes, steel structures have excellent seismic performance and high strength. It is especially suitable for post-disaster building reconstruction, national defense and civil recon...
