Embodiment 1
[0095] Taking the quality of coating as 100%, the coating described in this embodiment comprises the following components:
[0096]
[0097]
[0098] The calculation results of the above mass percentages retain one significant figure after the decimal point.
[0099]In the coating preparation process described in this embodiment, the selection of raw materials is as follows, the emulsion is a water-based acrylic emulsion, the deozone catalyst is a NiFe hydrotalcite structure catalyst, the particle size of the sand is 80-120 mesh, the The anti-settling agent is magnesium aluminum silicate, the dispersant is SN-5040, the wetting agent is LCN407, the antifreeze is propylene glycol, the film-forming aid is alcohol ester-12, the preservative is CBJ-4, and the thickener is hydroxyethyl Base cellulose and acrylic acid alkali swelling;
[0100] The molar ratio of nickel element and iron element in the NiFe hydrotalcite structure catalyst adopted in the present embodiment is 3:1...
Embodiment 2
[0117] Taking the mass of the coating as 100%, the coating in this embodiment comprises the following components in terms of mass percentages:
[0118]
[0119] The calculation results of the above mass percentages retain one significant figure after the decimal point.
[0120] The composition of the deozone catalyst and auxiliary agent used in this embodiment is the same as that of Embodiment 1.
[0121] The preparation method of deozone catalyst predispersion slurry, described method comprises the following steps:
[0122] (a) Add 100g of water in the sand mill cylinder, add the dispersant, then add the zirconium beads 100g and deozone catalyst powder with a particle size of 1mm in turn, wherein the dispersant and deozone catalyst powder mass ratio is 1:100, at 2200rpm Sand mill and stir for 30 minutes under the condition of the deozone catalyst to disperse the particle size of the deozone catalyst to below 50 microns; filter with a 200-mesh filter screen, remove the zir...
