Fireproof coating capable of effectively prolonging fireproof time

Abstract

The invention discloses a fireproof coating capable of effectively prolonging the fireproof time. The fireproof coating capable of effectively prolonging the fireproof time is prepared from, by weight, 5-9 parts of spruce stem essential oil, 20-22 parts of acrylic resin, 10-15 parts of magnesium carbonate, 10-15 parts of sodium bicarbonate, 6-8 parts of ammonium polyphosphate, 10-15 parts of pentaerythritol, 15-20 parts of an additive, 30-35 parts of an inorganic filler, 8-10 parts of a fire retardant and 20-25 parts of a solvent. The fire retardant comprises 13-14% of antimony dioxide, 0.2-0.3% of ammonium sulfate, 10-20% of magnesium hydroxide, 10-20% of citric acid, and the balance of diatomite. The fireproof coating capable of effectively the prolonging fireproof time increases the flame retardation effect of a coat layer and prolongs the fireproof time of the coat layer, and the effective fireproof time is above 3 times that of present fireproof coatings; and the fire retardant has the advantages of reasonable formula, low cost and good flame retardation effect.

Description

technical field [0001] The invention relates to the field of fireproof products, in particular to a fireproof coating which can effectively prolong the fireproof time. Background technique [0002] With the rapid development of my country's economic construction, a large number of steel structure buildings appear in public buildings, commercial buildings and other high-rise buildings and industrial plants. Steel has good tensile strength, but as the temperature rises, especially when the temperature reaches 400-600°C, its strength drops almost linearly, and when the temperature reaches above 600°C, the steel almost loses its bearing capacity. Therefore, it is very important to take effective protection measures for the steel structure so that it can avoid the direct burning of high-temperature flames in the event of an accident, delay the collapse time, and provide precious time for fire rescue. At present, countries around the world have adopted a variety of methods for fi...
