Abstract

The invention provides a fire-resistant paint which is characterized by comprising 12-20% of polyurethane acrylate, 16-25% of poly(N-isopropylacrylamide) modified magnesium hydroxide, 1.2-3.6% of urea, 0-8.5% of anionic surfactant, 2.8-6% of assistant, 2.2-4.6% of titanium white, 3.5-5% of borax and 30-45% of water. The fire-resistant paint has the advantages of favorable flame-retardant effect, environment friendliness and low toxicity.

Description

technical field [0001] The invention relates to a fireproof coating. Background technique [0002] Fireproof coating is a special coating used on the surface of flammable substrates, which can reduce the flammability of the surface of the coated material, retard the rapid spread of fire, and improve the fire resistance limit of the coated material. The flame retardant mechanism of fire retardant coatings using magnesium hydroxide as a flame retardant is: (1): magnesium hydroxide acts as a flame retardant filler, which has a diluting effect on the polymer matrix; (2): the decomposition reaction of magnesium hydroxide It is an endothermic reaction and releases a large amount of water; (3): The water vapor generated by the reaction dilutes the concentration of combustible gas and oxygen, making the combustion reaction more difficult; (4): When magnesium hydroxide reacts with certain polymerizations, It can be catalyzed to form carbon charcoal; (5): The magnesium oxide produced...
