Embodiment 1
[0021] The coating composition with air purification function of this example is as follows:
[0022] Modified bentonite formaldehyde adsorbent 40%, modified bentonite 8%, modified sepiolite 15%, kaolin 13%, nano silver-loaded antibacterial agent 0.5%, titanium dioxide 6.5%, calcium carbonate 9.7%, diatomite tailings 4%, methyl cellulose 2.7%, wood fiber 0.6%.
[0023] The modified bentonite formaldehyde adsorbent is obtained by heating bentonite in sulfuric acid or hydrochloric acid, and then irradiating with microwaves. The specific preparation method is operated according to Chinese patent application 201610244147.4.
[0024] Modified bentonite is obtained by mixing bentonite with sodium carbonate or sodium fluoride at a mass ratio of 24:1 for 7 days, then drying at 80-100°C, and crushing to 320 mesh. The specific preparation method is as follows: crush the bentonite raw ore, select bentonite with a montmorillonite content of ≥80% (mass ratio), the mass percentage is 96%,...
Embodiment 2
[0031] The coating composition with air purification function of this example is as follows:
