Particularly, in recent years, environmental pollution problems such as viruses, avian influenza viruses, and haze have been caused, and people are more aware that the purification of a home environment, the cleaning of outdoor air, the protection of water resources, atmospheric resources, and the like are related to human health, and a healthy living environment and sanitary quality are favored and valued by people, and how to effectively control the propagation of bacteria is still the focus of make internal disorder or usurp. Therefore, safe, nontoxic and pollution-free antibacterial products become the demands of consumers. The antibacterial material is a functional material which can kill or inhibit the proliferation of non-beneficial bacteria, and can be added into rubber, plastics, ceramics, cotton fabrics, medical equipment, ceramics, buildings and the like to prepare antibacterial products, thereby effectively preventing the invasion of bacteria and viruses and providing a healthy living environment for people.
In addition, in recent years, the indoor decoration is increasing day by day, and because many people do not know the indoor air pollution deeply and pay attention to the indoor air pollution insufficiently, the indoor air formaldehyde pollution generally exists and the phenomenon that the indoor air formaldehyde pollution seriously exceeds the standard exists. According to reports, all artificial fiber boards for indoor air decoration contain formaldehyde binders, formaldehyde in decoration materials can be released for 3 to 15 years, the formaldehyde is extremely harmful to human health, and especially has great potential hazards to pregnant women, children and the like.
Under such a background, the use of the antibacterial and environment-friendly material has become an important means for people to kill harmful bacteria, inhibit the growth and reproduction of harmful bacteria, and remove formaldehyde in the air to improve the health level of human beings. Over the last millennium, the emergence of SARS and avian influenza, especially H7N9 avian influenza in the eastern area of China, 3 months and 3 months in 2013, has greatly increased the desire and increase of people for a healthy environment.
Patent application CN105036804A discloses a health-preserving antibacterial ceramic glaze which is composed of the following materials in parts by weight: 10-30 parts of shell, 5-15 parts of bone meal, 5-10 parts of aluminum oxide, 0.1-0.5 part of ferric oxide, 5-15 parts of spodumene, 3-10 parts of tin oxide, 10-30 parts of germanite, 5-10 parts of crystal, 1-5 parts of talc and 2-10 parts of diatom ooze; and the basic formula of the common transparent glaze is as follows: 10-15 parts of limestone, 20-30 parts of feldspar, 1-5 parts of zinc, 20-30 parts of quartz and 1-4 parts of magnesium carbonate.

The photocatalyst generates higher photocatalytic activity than common zinc oxide under illumination, and improves antibacterial ability; in the absence of illumination, the antibacterial agent still has strong antibacterial effect due to the antibacterial ions of silver, zinc, rare earth metals and the like. The preparation method adopts an organic matter complexing method and a spray pyrolysis method. The doped nano zinc oxide can be directly mixed with other materials for use, or can be used as an additive to be added into materials such as plastics, ceramics, fibers, wood, rubber, glass, cement, metal and the like to prepare various photocatalytic and antibacterial materials and products.

wherein, the temperature in the step (2) is reduced to 25-30 ℃, 1/3 accelerant and 1/2 dispersant are added for mixing and grinding; then 1/3 accelerator and 1/2 dispersant are added and mixed, and the mixture is ground; and finally adding the rest 1/3 accelerator to obtain the final product.
6. The method for preparing the high-efficiency antibacterial material for ceramics as claimed in claim 2, characterized by comprising the steps of:
(1) dissolving an activating agent in water, adding nano zinc oxide, nano silver and active calcium, mixing and uniformly stirring, and heating to obtain a mixture 1;
(2) after the mixture 1 is cooled, gradually adding an accelerant and a dispersing agent, mixing and grinding to obtain the composite material;
wherein, the temperature in the step (2) is reduced to 25-30 ℃, 1/3 accelerant and 1/2 dispersant are added for mixing and grinding; then 1/3 accelerator and 1/2 dispersant are added and mixed, and the mixture is ground; and finally adding the rest 1/3 accelerator to obtain the final product.
7. Use of the highly efficient antibacterial material for ceramics according to any one of claims 1 to 4 in the preparation of ceramics.
