Study on Inorganic Organic Coating and Weather Resistance of Rutile Titanium Dioxide
A study was conducted on the inorganic,organic,and inorganic organic composite coating process of rutile titanium dioxide.The results showed that the optimal process for CeO2 inorganic coating was a titanium dioxide slurry concentration of 400 g/L,a stirring speed of 550 r/min,a CeO2 dosage of 3%,and a dispersant dosage of 0.4%.The optimal process for KH570 organic coating was a KH570 coating dosage of 3%.After inorganic,organic,and inorganic organic composite coating treatment,the Zeta potential values of titanium dioxide were-56.4,-47.9,and-65.5 mV,and the complete precipitation time of the samples was 14,11,and 21 days.Inorganic organic coating treatment can effectively improve the dispersibility of redstone type titanium dioxide.CeO2 can significantly reduce the photocatalytic activity of rutile titanium dioxide powder and improve its weather resistance,while KH570 has little effect on the photocatalytic activity of rutile titanium dioxide powder.
