Performance test
The same PVC rubber particles as those obtained in examples 1 to 5 and comparative examples 1 to 2 were prepared to obtain toys, and the PVC rubber particles obtained in examples 1 to 5 and comparative examples 1 to 2 were tested by using the method for testing the antibacterial property of antibacterial plastics of QB/T2591-2003 as a test standard.

It can be seen from the combination of example 1, comparative example 2 and table 3 that the number of bacteria on the surface of the toy is greatly reduced when the nano silver is added to the PVC rubber particles, which indicates that the PVC rubber particles prepared in example 1 have good antibacterial effect, probably because the bacteria on the surface of the toy are killed due to the existence of the nano silver and the nano silver has good antibacterial effect on the bacteria after the nano silver is added to the PVC rubber particles, so that the bacteria are not easy to grow and propagate on the surface of the toy.
It can be seen from the combination of example 1 and example 3 and table 3 that, when nano silver is combined into zinc oxide, the antibacterial ability of the toy prepared from pvc colloidal particles is greatly enhanced, probably because zno prepared in the present application and nano silver have a good synergistic effect, so that the antibacterial ability of nano silver is stronger, and the antibacterial ability of the toy is greatly enhanced.
It can be seen from the combination of example 1 and example 2 and table 3 that, although the antibacterial ability of example 1 is stronger than that of example 2, which may be due to the more added amount of nano silver in example 1, the cost of nano silver is expensive, so if too much nano silver is used, the production cost is greatly increased, thereby reducing the competitiveness of the product.
It can be seen from the combination of example 2 and example 3 and table 3 that when the nano silver is added as the nano silver prepared in the present application during the preparation of the antibacterial agent, the antibacterial ability of the toy is greatly improved, probably because zno prepared in the present application has better compatibility with the nano silver prepared in the present application, so that the antibacterial ability of the nano silver is improved under the action of zno.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
