Abstract
The invention relates to a high efficient fire-retardant colorful polyurethane waterproof paint. The paint is composed of two parts namely a main component A and a curing agent B; wherein the main component A comprises an inorganic nano powder fire retardant, which can help to increase the crosslinking density during the coating curing process, reduces the contact surface during the burning process, absorbs a large amount of heat, reduces the substrate temperature, and forms a carbonization fireproof layer to obstruct the flame spread, and also comprises an organic fire retardant, which has a melting point of 900 to 1050 DEG and has a synergetic effect when the organic fire retardant is cooperatively used with the inorganic fire retardant; and the curing agent B comprises an organic fire retardant, which does not carry out chemical reactions with polyurethane raw materials and has a long lasting fire retardant function. Because two components both have the fire retardant function, the fire retardant effect is more prominent, when the two components are co-used in the construction. The coating gel layer which is formed after the paint is painted on the surface of a building has a reliable waterproof function, will not fall off from the building permanently, is hard to burn by open fire, can satisfy the high waterproof and fireproof requirements of buildings, and has a very strong practicality.
