The present invention provides a kind of outdoor air auto purification catalytic nanometer coating and preparation methods.Photochemical catalyst is immersed in foaming agent, mixing is so that foaming agent Coated photocatalyst, surface is sprayed at after liquid glass is mixed with ionized water, heat drying, obtaining has the composite Nano catalysis material of micropore to surface, it is mixed with building external paint after being uniformly dispersed, you can obtain kind of an outdoor air auto purification catalytic nanometer coating.This method passes through in catalyst surface encapsulated blowing agent, liquid glass; not only it is uniformly dispersed in exterior coating; and the easy light transmission of liquid glass layer, air are easily contacted by micropore with nano-photocatalyst, improve the efficiency of light energy utilization and photocatalytic degradation effect; and can effectively protect photochemical catalyst; effectively prolong the service life, in use can efficient releasing negative oxygen ion, air quality can be significantly improved; and cost is relatively low, can large-scale promotion production. |
