Abstract

The invention discloses a fire retardant coating with photocatalytic performance and a preparation method thereof. The fire retardant coating is obtained by mixing and stirring a base material, a catalyst, a charring agent, a foaming agent, filler, a pigment, a solvent, a disperser, a dryer, a drying aid and a nano-mother solution. By adopting the preparation method provided by the invention, the environment pollution can be furthest reduced, the recycling economical production of the product can be realized and about 20% of the cost can be reduced; the fire retardant coating prepared by the invention has excellent performances of high strength, rapid hardness, washing resistance, water resistance, alkali resistance and freezing resistance, particularly has an outstanding feature of degrading the formaldehyde gas in the room through photocatalysis and has a natural, non-toxic, pollution-free environment-friendly safety performance.

Description

technical field [0001] The invention relates to a fireproof coating, in particular to a fireproof coating with photocatalytic performance prepared from industrial waste residues, and belongs to the field of fireproof coatings. Background technique [0002] Water-quenched slag mainly refers to the granulated slag discharged from the iron-making blast furnace. It generally refers to an industrial waste slag that flows out of the high-temperature molten state in the furnace and is quenched and quenched by water. It is a glass structure material with high potential activity. As a material "resource" with high energy and high energy consumption, water-quenched slag is far from enough for its comprehensive utilization. Statistics show that nearly 67% of slag has been well utilized at present, but there are still a large amount of slag that is simply and extensively used as building aggregates and road fillers, and is wasted in vain. A considerable number of enterprises simply sell...
