The photocatalyst layer is sprayed on the surface of the comparative example 1, the odor grade is 0.5 grade higher than that of the comparative example 2, and the VOC test result is slightly superior to that of the comparative example 2, which shows that the photocatalyst sprayed on the surface is favorable for improving the odor property and VOC emission of the material. Comparative example 3 coconut shell activated carbon is added into the adsorption coating, the odor performance and VOC test result are slightly higher than those of comparative example 2, the odor grade and VOC adsorption quantity of the wall cloth are reduced to a certain extent, but the odor performance and VOC performance of the wall cloth are poor compared with those of other wall cloths (examples 1-2 and comparative example 1) overall, and the activated carbon and the resin film-forming agent are mixed to block pores on the surface of the activated carbon, so that the adsorption performance of the activated carbon is influenced.
The results in table 2 show that the wall cloth (examples 1-2) obtained by the invention has better formaldehyde degradation performance, wherein the example 1 is the optimal formula and process, the formaldehyde degradation rate is as high as 98.5%, and the wall cloth of the examples 1 and 2 has the carbon dioxide generation rate, which indicates that the nano catalytic particles in the wall cloth degrade formaldehyde; the formaldehyde degradation rate of the comparative example 1 is lower than that of the wall cloth obtained by the invention (examples 1-2), but 46.6% of carbon dioxide is generated, which shows that the photocatalyst sprayed on the surface degrades formaldehyde through chemical catalysis instead of simple physical adsorption; the formaldehyde degradation rate of comparative example 3 is 27.6%, no carbon dioxide is generated, which indicates that the wall cloth retains weak adsorption effect; the formaldehyde degradation rate and the carbon dioxide generation rate in the comparative example 2 are both 0, which indicates that the wall cloth has no adsorption degradation effect.
The results in table 3 show that the wall cloth (examples 1-2) obtained by the invention has good antibacterial activity, wherein example 1 is the best formula and process, and the antibacterial rate is as high as 98%; the antibacterial activity of the comparative examples 1 to 3 is poor, wherein the wall cloth of the comparative example 1 is better than that of the comparative examples 2 to 3, because the nano photocatalyst sprayed on the surface has certain antibacterial activity but limited antibacterial effect.
