Abstract

The invention provides a nanometer fireproof antibacterial environment-friendly coating and a preparation method thereof. The preparation method comprises a step (1) of evenly dispersing light calcium carbonate, talcum powder, titanium dioxide, ethylene glycol and softened water at a high speed, controlling the dispersion speed to be 1000-1500 turns / min, and controlling the dispersion time to be 30-60 min; a step (2) of grinding the aforementioned slurry through a grinder to fineness of 34-45 microns; a step (3) of adding texanol, acrylic emulsion, dodecyl trimethyl ammonium chloride, ethoxylated octyl phenol, cacumen biotae ethanol extract, christina loosestrife herb ethanol extract and hydroxypropyl methylcellulose, and performing stirring for 40-60 min; a step (4) of adding ammonium polyphosphate, melamine, pentaerythritol, ODOPB and nano graphene oxide, and performing ultrasonic shearing for 60-100 min. According to the coating, an environment-friendly formula is adopted, and the coating has very good fire resistance, bacterium resistance and mold resistance.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a nano fireproof, antibacterial and environmental protection coating and a preparation method thereof. Background technique [0002] The method of coating fireproof paint on its surface for fireproof protection can not only maintain the excellent performance of the original organic synthetic material, but also be economical and applicable. The application of fire retardant coatings on organic synthetic materials also has broad prospects. In addition, ordinary steel loses its structural strength when heated to about 540°C. Concrete structures are also prone to cracking and disintegration under the action of high-temperature flames. Therefore, the fire protection of steel structures and concrete structures, so that they can prolong the time of deformation and damage when a fire occurs, wins time for fire extinguishing and reduces fire losses, has received great attention.
