Abstract

The invention provides a fireproof corrosion resistant coating. The fireproof corrosion resistant coating has the beneficial effects that thermoplastic acrylic resin, polyurethane resin and organic silicon resin are combined to be used as a main body of the fireproof corrosion resistant coating; through combination of the three kinds of resin, the coating not only has good light and color retention properties and water and chemical resistance but also is convenient to construct, has high drying speed and saves energy; as high temperature resistant mullite and silica fibers are also added to the coating, not only can the mechanical strength of coats be obviously improved but also the weather and corrosion resistance of the coats can be improved; in case of a fire, through synergy of various components in the formula, the coating has good flame retardant effects and is less in fuming.

Description

technical field [0001] The invention relates to a fireproof and corrosion-resistant paint, 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 fireproof and corrosion-resistant coatings and the requirements of current national standards for fire-resistant and corrosion-resistant coatings, the most suitable classifications are: structural fire-resistant and corrosion-resistant coatings and decorative fire-resistant and corrosion-resistant coatings; according to their solubility, they can be divided into They are water-based fireproof ...
