Problems solved by technology

[0004] (1) The weather resistance and water resistance of the product generally cannot meet the requirements of GB1907 outdoor fireproof coating, and can only be used indoors, not outdoors;
[0005] (2) In the event of a hydrocarbon fire, the film-forming substances of these fire retardant coatings cannot withstand the sharply increased temperature and are quickly burned, and cannot play the role of preventing hydrocarbon fires;
[0006] (3) Poor performance in anti-corrosion, anti-rust, acid and alkali resistance

Abstract

The invention provides a hydrocarbon-resistant outdoor ultrathin fireproofing coating for steel structures. The fireproofing coating consists of a component A and a component B, wherein the component A includes liquid epoxy resin OER-95 and propylene glycol monomethyl ether, and the component B includes an aquatic amine curing agent 751, de-ionized water, propylene glycol monomethyl ether, ammonium polyphosphate, melamine, pentaerythritol, chlorinated paraffin, nano TiO2 slurry, expanded graphite, compound iron-titanium powder, a dispersing agent, a wetting agent and a deforming agent, and the components A and B are mixed at 1: (5.5-6) in percentage by mass. The fireproofing coating, as an aquatic environmentally-friendly fireproofing coating, is quite low in organic compound discharge, can bear rapid temperature increasing of hydrocarbon fire, and is excellent in chemical corrosion resistance, heat resistance, acid-base resistance property, water resistance, electric insulating performance and mechanical strength; the fireproofing coating can be widely used for protecting outdoor steel structures.

Description

technical field [0001] The invention relates to the technical field of metal surface coatings, in particular to a hydrocarbon-resistant outdoor ultra-thin fireproof coating for steel structures. Background technique [0002] With the rapid development of my country's economy, the demand for energy is increasing, and oil exploration and petrochemical enterprises have higher and higher requirements for the fire safety performance of steel structures. Environmental characteristics of offshore oil platforms and petrochemical enterprises: First, the natural environment is harsh, high temperature, humidity, high salinity, wind and sun, and large temperature difference between day and night; second, raw materials and products are flammable and explosive hydrocarbon chemicals, hydrocarbons The quasi-fire has the characteristics of extremely fast flame propagation and temperature rise, and the temperature of the fire scene can quickly rise to above 1000°C. Once a fire breaks out, the...
