Diatomite micropowder-based interior wall paint capable of removing formaldehyde and peculiar smell in indoor air and preparation method thereof
The invention provides a diatomite micropowder-based interior wall paint capable of removing formaldehyde and peculiar smell in indoor air and a preparation method thereof, belonging to the field of diatom nano-materials. The diatomite micropowder-based interior wall paint provided by the invention overcomes the problems of low purifying efficiency and short-term purifying effect of toxic gas like formaldehyde in conventional interior wall paints, no release of negative ions, poor antibacterial and mildew-resistant effects and high cost in the prior art. The diatomite micropowder-based interior wall paint comprises, by weight, 30 to 40 parts of diatomite micropowder, 10 to 20 parts of a nanometer titanium dioxide/diatomite composite photocatalysis material, 11 to 21 parts of calcined kaolin, 5 to 15 parts of heavy calcium carbonate, 2 to 8 parts of light calcium carbonate, 0.5 to 2 parts of cellulose ether, 1 to 3 parts of lignocellulose, 1 to 5 parts of redispersible latex powder and 7 to 17 parts of white cement. The interior wall paint has formaldehyde and toluene purifying efficiency of 86.8 to 88.2% and 52.1 to 54.2%, respectively, formaldehyde and toluene purifying effect persistence of 72.8 to 74.0% and 34.8 to 36.0%, respectively, an average negative ion increasing amount of 126 to 131/s.cm2 and an antibacterial rate of 92 to 94%.
