Problems solved by technology

The disadvantage of silver-based antibacterial ceramics is that when silver ions are applied to ceramics, after high-temperature firing, the silver ion content may be insufficient, and the bactericidal effect is not ideal. The reason is that silver ions will volatilize during high-temperature firing, resulting in poor antibacterial effect.
[0003] The disadvantages of titanium-based antibacterial ceramics are: the antibacterial effect is poor after high temperature firing, and photocatalysis is required to sterilize. At the same time, the antibacterial film and ceramics are easy to fall off

Abstract

The invention discloses a far infrared antibacterial ceramic glaze, wherein the far infrared antibacterial ceramic glaze is prepared by mixing and firing zirconium phosphate silver-loaded antibacterial powder, germanite, iron-free feldspar, quartz sand, calcium phosphate, magnesium carbonate and zinc oxide powder at the mass ratio of (2-10):(5-15):(15-25):(15-20):(5-10):(2-6):(5-10). The invention further discloses a preparation method of the far infrared antibacterial ceramic glaze. The far infrared antibacterial ceramic glaze has a better bactericidal effect and is good in antibacterial endurance, the silver ion is not volatilized when being roasted at the high temperature of 1200 DEG C, the loss of the antibacterial silver component is reduced, and the stability of the antibacterial property is guaranteed.

Description

technical field [0001] The invention relates to the technical field of sanitary ceramics, in particular to a far-infrared antibacterial ceramic glaze and a preparation method thereof. Background technique [0002] In the prior art, silver-based antibacterial ceramics and titanium-based antibacterial ceramics are the most common antibacterial ceramics. The disadvantage of silver-based antibacterial ceramics is that when silver ions are applied to ceramics, after high-temperature firing, the amount of silver ions may be insufficient, and the bactericidal effect is not ideal. The reason is that silver ions will volatilize during high-temperature firing, resulting in poor antibacterial effect. [0003] The disadvantages of titanium-based antibacterial ceramics are: the antibacterial effect is poor after high-temperature firing, and photocatalysis is required to sterilize. At the same time, the antibacterial film and ceramics are easy to fall off. [0004] In view of this, the p...
