Problems solved by technology

The use of titanium dioxide in the prior art is directly added, and there is no corresponding physical change in the mixture, which is equivalent to "pure" titanium dioxide. However, according to research, it is found that "pure" titanium dioxide has no antibacterial properties under visible light.

Embodiment 1

[0017] Embodiment 1: a kind of antibacterial glaze and preparation method thereof, the raw material share of glaze is: 40 parts of titanium dioxide, 0.5 part of zinc nitrate, 0.5 part of cerium nitrate, 3 parts of glacial acetic acid, 8 parts of distilled water, 30 parts of absolute ethanol parts, 0.2 parts of surfactant, 800 parts of granite.

[0018] The specific preparation method is as follows: the antibacterial agent is prepared separately, comprising the steps of:

[0019] a. Preparation of antibacterial agent: Add 3 parts of glacial acetic acid and 8 parts of distilled water to 30 parts of absolute ethanol, then add 0.5 part of zinc nitrate and 0.5 part of cerium nitrate, and then add 0.2 part of sulfonic acid anionic surfactant The main function is to disperse the particles on the ceramic surface after glazing, which is used to improve and enhance the mechanical properties of the material, and can also reduce the sintering temperature of the ceramic; use an electric st...

Abstract

The invention discloses an anti-bacterial glaze and a preparation method thereof. The glaze comprises the following raw materials in parts by mass: 40-50 parts of titanium dioxide, 0.5-0.8 part of zinc nitrate, 0.5-0.8 part of cerous nitrate, 3-5 parts of glacial acetic acid, 8-12 parts of distilled water, 30-40 parts of absolute ethyl alcohol, 0.2-0.3 part of a surfactant and 800-1200 parts of granite. The preparation method comprises the following steps: preparing an antibacterial agent, mixing for preparing glaze slip and sintering at a high temperature, so as to obtain the anti-bacterial glaze. According to the ceramic glaze with an anti-bacterial function, provided by the invention, by modifying titanium dioxide and doping titanium dioxide with related metal elements, a visible region of the titanium dioxide is enabled to have an antibacterial property; moreover, the ratio of all components is scientific and reasonable, a glaze surface is smooth, uniform color, good dispersity, high acid resistance and high alkali resistance are realized and the application range is wider.

Description

technical field [0001] The invention relates to the field of silicate products, in particular to an antibacterial glaze and a manufacturing method thereof. Background technique [0002] my country is a large ceramic production and consumption country. At present, the annual output of architectural ceramics is more than 650 million square meters, and the number of ceramic sanitary ware is about 60 million. With the progress of social civilization and changes in the environment, people are no longer satisfied with the beauty and durability of traditional ceramics. And other general functions, it is more desirable to have functions such as sterilization, disinfection, and deodorization. [0003] Traditional ceramics are mainly white, and the glaze only uses zirconium silicate to play a white role, and has no other functions, and the traditional ceramic glaze is uneven under a magnifying glass, making it easy for dirt and bacteria to hide and multiply; later, in traditional ceram...
