TABLE 1
As can be seen from the data in table 1:
the antibacterial and anti-mite spray obtained in examples 1 to 5 has an antibacterial rate of 97.54 to 99.91% for escherichia coli, an antibacterial rate of 97.81 to 99.95% for staphylococcus aureus, and a repelling rate of 96.14 to 99.52% for mites.
Specifically, by comparing the data of example 1 with the data of comparative examples 1 to 3, the antibacterial rate and the aversion rate to mites of the antibacterial and acaricidal spray prepared without adding the organic quaternary ammonium salt are greatly reduced; the data of the comparative example 1 and the comparative example 4 also show that the antibacterial rate and the aversion rate to mites of the antibacterial and anti-mite spray obtained without adding the nano silver solution are greatly reduced; comparing the data of the example 1 and the comparative examples 7-9, the antibacterial rate and the mite avoidance rate of the antibacterial and mite-proof spray obtained without adding the aloe extract are greatly reduced; comparing example 1 with comparative examples 10 to 12, it can be seen that the antibacterial rate and the aversion rate to mites of the antibacterial and anti-mite spray obtained without adding the photocatalyst are greatly reduced; in conclusion, the spray with excellent antibacterial performance and mite-proof effect can be obtained only by simultaneously adding the combination of the organic silicon quaternary ammonium salt, the nano-silver solution, the photocatalyst, the chitosan, the plant extract and the chrysanthemum polyester in specific parts and utilizing the mutual matching of various antibacterial and antiviral components. Further comparing the embodiment 1 with the embodiments 4 to 5, it can be found that the antibacterial and anti-mite effect of the antibacterial and anti-mite spray obtained by using silver-doped nano titanium dioxide and silver/cerium co-doped nano zinc oxide as the photocatalyst in the embodiment 1 is more excellent.
The applicant states that the invention is described by the above examples to describe an antibacterial and anti-mite spray and its preparation method and application, but the invention is not limited to the above examples, i.e. it does not mean that the invention must be implemented by the above examples. It should be understood by those skilled in the art that any modification of the present invention, equivalent substitutions of the raw materials of the product of the present invention, addition of auxiliary components, selection of specific modes, etc., are within the scope and disclosure of the present invention.
