Abstract

The invention provides a fireproof building coating. A main body of the fireproof coating adopts combination of thermoplastic acrylic resin, hydroxy acrylic resin and organic silicon resin, and due to the combination of the resin, the coating not only has the good light and color preserving property and the water and chemical resistance property, but also is convenient to construct, high in drying speed and economical in energy. According to the fireproof building coating, mullite fibers and silica fibers which can resist high temperature are added, and therefore not only can the mechanical strength of a coating layer be significantly improved, but also the weather resistance and corrosion resistance of the coating layer can be improved. When a fire disaster occurs, through the synergistic effect of all the components in the formula, the fire retardant effect is good, and smoke formation is little.

Description

technical field [0001] The invention relates to a fireproof architectural coating, which belongs to the technical field of decorative materials. Background technique [0002] Fire retardant coatings are also known as flame retardant coatings. Applying such coatings on the surface of some flammable materials in buildings can improve the fire resistance of flammable materials, or slow down the speed of flame spread, and prevent burning within a certain period of time. Control the growth of the fire and give people time to fight the fire. According to the function and function of fire retardant coatings and the requirements of current national standards for fire retardant coatings, the most suitable classifications are: structural fire retardant coatings and decorative fire retardant coatings; according to their solubility, they can be divided into water-based fire retardant coatings and oil-based fire retardant coatings ; According to its flame retardant mechanism, it can be ...
