Abstract

The invention relates to a kieselguhr-based porous ceramics, a preparation method thereof and a method for loading Ag doped with nano TiO2 on the same, belonging to the technical field of a kieselguhr inorganic material. The kieselguhr-based porous ceramics is made from kieselguhr, a sintering auxiliary agent, a dispersing agent, a binder and water in the weight ratio of 60-92:8-40:0.01-2:0:001-1:100-450. The kieselguhr-based porous ceramics has functions of absorption and filtration, and can absorb granules in fluid when the fluid passes through the lieselguhr-based porous ceramics. Ag doped with nano TiO2 is loaded on the kieselguhr-based porous ceramics to generate kieselguhr-based porous ceramics loading the Ag doped with TiO2. The laden anatase-type nano TiO2 has large specific surface area. The effects of filtration, photochemical catalysis and sterilization of the kieselguhr-based porous ceramics loading the Ag doped with nano TiO2 are greatly increased.

Description

technical field

[0001] The invention belongs to the technical field of diatomite inorganic materials, and relates to a diatomite-based porous ceramic and a preparation method thereof, as well as a method for loading silver-doped nano-titanium dioxide on a diatomite-based porous ceramic. Background technique

[0002] With the development of industrialization and urbanization, environmental pollution around the world is becoming more and more serious, especially the pollution of indoor air is worrying. Various organic decoration and decoration materials, furniture, modern office appliances and household appliances, etc., continuously release pathogenic and carcinogenic substances such as formaldehyde, benzene, benzopyrene and ammonia. According to tests, the degree of indoor air pollution is 5 times that of outdoor air. ~20 times, while urban residents spend more than 90% of their time indoors. Therefore, people's health and even life have been endangered unprecedentedly, lea...
