Performance testing
After 9 wall surface samples with the same size and the same specification are respectively subjected to the mildew-proof insect-repelling environment-friendly coating coatings of the embodiments 1-4 and the comparative examples 1-10, 14 coating samples with completely consistent shapes and sizes are prepared. The test results were as follows:
the test method comprises the following steps:
firstly, carrying out mildew resistance test on 14 coating sample plates, introducing a 3-6 mm nutrient medium into the blood of a mildew, solidifying the nutrient medium, and placing a sample on the surface of the nutrient medium. The sample surface was uniformly sprayed with the sterilized arman orchid suspension of a nebulizer so that the entire sample surface was wetted with the mixed spore suspension. The plate covered with the inoculated test sample is placed under the proper temperature and humidity for culture, the culture time is 28d, if too much mould grows on the surface of the asbestos, the mould reaches high grade, namely the test is meaningless, and the mould can be less than 28 d. And (4) observing the growth condition of the mold, and grading, wherein the grading judgment standards of different standards are different. At the end of the test, the appearance of the sample was immediately checked and the sample was photographed if necessary. If the test only checks the visual effect. The sample should be taken out from the incubator, and the growth of mold, thallus and hyphae on the surface of the sample plate can be observed directly from the front or the side. The examined sample should be examined first with the naked eye and, if necessary, with a magnifying glass (magnification of about 50).
Grade 0-no significant mold growth under about 50 times magnification;
grade 1-no or very little mold growth is visible to the naked eye, but significant growth is visible under a magnifying glass;
grade 2, wherein the mold growth is obviously seen by naked eyes, and the coverage area on the surface of the sample is 10 to 30 percent;
grade 3, wherein the mold growth is obviously seen by naked eyes, and the coverage area on the surface of the sample crystal is 30 to 60 percent;
grade 4-the mold growth is clearly visible to the naked eye, and the coverage area on the sample surface is more than 60%.
Secondly, the 14 paint coating sample plates are subjected to insect repellency test, the method needs to put the samples into a box with an outlet and the same number and types of insects for testing for a certain time (usually 2 hours), the nutrition temperature, humidity, pH, time and the like need to be strictly controlled in the process, and finally the insect repellency is judged by observing the type and the number of the insects. The quantity of the insects before and after calculation is compared in percentage, and the lower the percentage of the remaining insects is, the better the insect repelling performance is.
The results of the mold resistance tests of examples 1 to 4 and comparative examples 1 to 10 are shown in Table 1.
TABLE 1
As can be seen from the data in table 1, in examples 1 to 4, the compositions all include zinc oxide, diiodomethyl polymethylsulfone and tributyltin fluoride, and the mildew-proof performance is better, especially in example 3, the best mildew-proof effect is achieved by the mixture ratio of zinc oxide, diiodomethyl polymethylsulfone and tributyltin fluoride;
in comparative examples 1 to 3, one component of zinc oxide, diiodomethyl polymethyl sulfone and tributyltin fluoride is respectively absent, so that the mildew resistance is reduced; in comparative examples 4-6, two components of zinc oxide, diiodomethyl polymethyl sulfone and tributyltin fluoride are respectively deleted, the mildew resistance is obviously reduced, and the reduction range of the performance is larger than the sum of the reduction ranges of the performances of the components which are deleted; comparative example 7, which lacks all components of zinc oxide, diiodomethyl polymethylsulfone and tributyltin fluoride, has the worst antifungal effect; therefore, the zinc oxide, the diiodomethyl polymethyl sulfone and the tributyltin fluoride produce synergistic effect.
The results of the insect repellency test for examples 1 to 4 and comparative examples 1 to 10 are shown in FIG. 1.
As can be seen from the data in fig. 1, in examples 1 to 4, the two components including the lemongrass and the chicory ethanol extract have good insect-repellent performance, and particularly, the best insect-repellent effect is achieved under the condition of the mixture ratio of the lemongrass to the chicory ethanol extract in example 3;
in comparative examples 8 to 9, one component was missing, and the insect-repellent performance was reduced; in comparative example 10, two components were deleted, respectively, the insect-repellent performance was significantly reduced, and the reduction in performance was greater than the sum of the reductions in performance of the component lacking; therefore, a synergistic effect is generated between the two components of the lemongrass and the chicory ethanol extract.
It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
