The anion formaldehyde-removing compound in the embodiment firstly utilizes the characteristic that the natural polar mineral compound generates anions to adsorb organic volatile matters such as formaldehyde and the like in the vehicle, and can also perform bacteriostasis, degerming and odor removal on the space in the vehicle. The natural polar mineral compound can be compound powder composed of tourmaline and one or more of six-ring stone, medical stone and gull rock. The photocatalyst compound in the anion aldehyde-removing compound can be composite powder consisting of any two or more of nano titanium oxide, nano zinc oxide, nano tin oxide, nano silver and silver phosphate. The photocatalyst can generate a photocatalytic reaction similar to photosynthesis under the irradiation of light to generate free hydroxyl and active oxygen with extremely strong oxidizing power, has a very strong photo-oxidation-reduction function, can oxidize and decompose various organic compounds and partial inorganic matters, and decomposes organic pollutants into pollution-free water and carbon dioxide. However, the photocatalyst composite has limited effect when sunlight is insufficient or the concentration of chemical pollutants is high, so the natural polar mineral composite and the photocatalyst composite are comprehensively utilized to ensure the effect of removing harmful gases such as formaldehyde to the maximum, and the natural polar mineral composite and the photocatalyst composite can play a role durably and continuously under the condition that the environment is relatively stable, so the service life of the embodiment is fundamentally ensured.

Therefore, the present example also employs a sterilization stabilizer consisting of bamboo leaf extract, mulberry leaf extract, arborvitae extract and deionized water.
The bamboo leaf extract is used as a plant flavonoid, has typical bamboo leaf fragrance, good thermal stability, broad-spectrum antibacterial property and strong inhibition effect on bacteria, mould and yeast. Wherein the extract has stronger inhibiting effect on bacteria, such as salmonella typhi, escherichia coli, staphylococcus aureus, bacillus subtilis, proteus and bacillus thuringiensis, and is enhanced along with the prolonging of the action time and the increase of the concentration of the used extract.
The extract of the mulberry leaves in the embodiment preferably can provide a mulberry leaf extract and a broussonetia papyrifera leaf extract of high-purity mulberry leaf polysaccharide, and the broussonetia papyrifera leaf extract contains various antibacterial components and has an inhibiting effect on pathogenic bacteria such as staphylococcus aureus, pasteurella multocida, escherichia coli, salmonella, riemerella anatipestifer and the like. The arborvitae extract contains active substances such as tropolone and the like, and also has excellent bacteriostatic ability.

In the embodiment, the nano titanium oxide, the nano zinc oxide and the nano silver are compounded according to the weight ratio of 1:1: 1.
The tourmaline has better anion release capacity, and the medical stone has adsorbability, dissolubility, adjustability, biological activity, mineralization and the like, can adsorb free metal ions in water and is beneficial to prolonging the service life of the multi-effect disinfection spray for vehicles. Thereby delaying the inactivation of the photocatalyst compound and further enhancing the anti-scaling effect of the natural polar mineral compound. The nanometer tourmaline and the nanometer medical stone can also play the superfine effect of polar ores.

Test example 1
The components of examples 1-3 and comparative examples 1-4 were each prepared using the method of example 4.

TABLE 1 results of product stability test of examples 1-3 and comparative examples 1-4
Figure BDA0002491647310000101
As can be seen from Table 1, the reduction rates of the effective components of the examples 1-3 and the comparative examples 3-4 are less than 10%, and the test standards are met. Examples 1-3 are much lower than comparative examples 1-2, and examples 1-3 demonstrate that the formulations of the components of examples 1-3 are more stable and longer lasting. Among them, the reduction rate of the effective component of comparative example 1 is the highest, and it is presumed that the stability of the system of comparative example 1 is greatly reduced because no bactericidal stabilizer is added. In the comparative example 2, the stability of the product is difficult to ensure because no odor-removing compound hydrolat is added. Comparative example 3 the absence of nanoscale tourmaline and nanoscale medical stone although meeting the corresponding standards, the stability was slightly inferior to that of the examples. As can be seen from comparative example 4, the extraction criteria of the plant extract in the germicidal stabilizer also affected the stability of the system.
Test example 2
The components of examples 1-3 and comparative examples 1-4 were each prepared using the method of example 5. Testing the obtained sample by negative ions and removing harmful gases, wherein the testing equipment is negative ion testing equipment and an air quality detector of Shenzhen Wan instrument science and technology Limited; the formaldehyde test and TVOC test are carried out for 24h and 14d, and the test results of the test equipment are shown in Table 2.
Table 2 test results of examples 1 to 3 and comparative examples 1 to 4 for anion and harmful gas removal
Figure BDA0002491647310000111
As can be seen from Table 2, the anion release values 24h of examples 1 to 3 and comparative examples 3 to 4 were about 2000/cm3The effect of the disinfectant can be ensured. Meanwhile, the formaldehyde removal rate of examples 1 to 3 was higher than 24 hours at 14d, presumably because the concentration of the extract in the bactericidal stabilizer increased with the increase of the action time. In the examples 1-3, the formaldehyde removal rate can reach 97% in 24 h. The TVOC reduction rates of examples 1-3 and comparative examples 3-4 were also relatively stable at 14 d. Meanwhile, the method of example 5 is also reflected to prepare a stable and long-acting disinfection spray system.
Test example 3
The components of examples 1-3 and comparative examples 1-4 were each prepared using the method of example 6. And carrying out continuous antibacterial test on the obtained sample, wherein the detection standard is 5.2.7 continuous antibacterial test in the WST650-2019 antibacterial and bacteriostatic effect evaluation method, and the test time is 15 d. The test results are shown in Table 3.
TABLE 3 examples 1-3 and comparative examples 1-4 continuous antibacterial tests
Figure BDA0002491647310000121
As can be seen from Table 3, examples 1-3 and comparative examples 3-4 all met the standard that the sterilization rate was greater than 90%, and could achieve the effect of continuous antibacterial. Comparative example 1 has no bactericidal stabilizer, but has better antibacterial effect due to the negative ion formaldehyde-removing compound. Meanwhile, the method of the embodiment 6 can be used for preparing a stable and long-acting disinfection spray system.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
