Problems solved by technology

Among them, silver-based antibacterial ceramics have a good bactericidal effect, but require a large amount of silver ions and high production costs; and silver ions will volatilize when fired at high temperature, resulting in poor antibacterial effect; in addition, modern scientific research has found that silver ions and gold Ions can kill bacteria as well as human cells, and the finding raises concerns about whether long-term use of silver-based antibacterial products is harmful to the body
Titanium-based antibacterial ceramics have poor antibacterial effect when fired at high temperature, and require photocatalysis to sterilize; antibacterial film and ceramics are easy to fall off

Embodiment 1

[0022] An antibacterial ceramic product comprises the following raw material components in parts by weight: 25 parts of coal gangue, 15 parts of sea mud, 10 parts of shell powder, 3 parts of boron mud, 10 parts of ceramic clay, and 10 parts of potassium feldspar.

[0023] The preparation method of this antibacterial ceramic product comprises the following steps:

[0024] S1. Take each raw material component according to the above parts by weight, mix and pulverize it and pass through a 100-mesh sieve to obtain a powder;

[0025] S2. Add distilled water twice the total weight of the powder to the powder, ultrasonically disperse at room temperature, and then pour it into a ball mill for ball milling. The ball milling speed is 200r / min, and the time is 4h; then pass through a 300-mesh sieve to obtain a slurry ;

[0026] S3, the slurry is sprayed and granulated, and dry-pressed to form a green body;

[0027] S4. Dry the green body, and then fire the dried green body; the firing ...

Embodiment 2

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to an antibacterial ceramic product and a preparation method thereof. Background technique [0002] Because of its hard texture, fineness, high temperature resistance and other characteristics, ceramics are widely used in food utensils, decoration and other fields. At present, the use of ceramics is full of all aspects of our lives. With the progress of social civilization and the change of environment, people are no longer satisfied with the general functions of traditional ceramics such as beauty and durability, and hope to have functions such as sterilization, disinfection and deodorization, especially for daily-use ceramic products. [0003] Existing antibacterial ceramic products are the most common with silver series antibacterial ceramics and titanium series antibacterial ceramics. Among them, silver-based antibacterial ceramics have a good bactericidal effect, but require ...
