The invention discloses dolomite colored coating powder having an air-purifying function. According to the technical scheme, the dolomite colored coating powder is characterized in that ingredients include attapulgite pottery clay powder having the air-purifying function, calcined dolomite powder, acidified zeolite particles, colored portland cement, Paris plaster, white carbon black, calcium chloride, aerosil, expanded perlite, nanometer silver-loaded antibacterial powder, nanometer titanium dioxide, sodium pyrophosphate and powder defoaming agents. The ingredients of the dolomite colored coating powder having the air-purifying function are input three times into a stirring machine to be stirred evenly and packaged into the finished product. By the adoption of the colored coating, in indoor wall decoration, an artistic emboss effect of various embossed three-dimensional colored patterns can be achieved through spraying and manufacturing, after spraying, a coating is hard, the porosity is high, the specific surface area is large, adhesion is high, indoor formaldehyde, ammonia nitrogen, benzene and other harmful substances can be adsorbed and decomposed, and the functions of automatic humidification, flame retarding, mould prevention, sterilization, deodorization and air purification are achieved.
