Problems solved by technology

As ceramic tiles commonly used in people's living rooms, there will always be some dead spots for pollution and bacterial growth, especially in places such as home kitchens and bathrooms, where bacteria are prone to breed. The surface of ceramic tiles has tiny pinholes that are invisible to the naked eye. After a long time, bacteria are easy to accumulate, breed and even infect, seriously affecting the health of the body
Traditionally, ceramic tiles prepared by directly adding organic antibacterial agents and inorganic antibacterial agents to impart antibacterial functions to ceramic glazes are often easily agglomerated and unevenly dispersed in the glaze, resulting in poor antibacterial durability of the prepared ceramic tiles, and antibacterial agents cannot When the desired antibacterial effect is achieved

preparation example Construction

[0041] A preparation method of antibacterial ceramic glaze, the antibacterial agent is added to the ceramic glaze according to the weight percentage and mixed evenly, the suspending agent and the debonding agent are added into the ceramic glaze containing the antibacterial agent according to the weight percentage After mixing the raw materials evenly, add water and ball mill for 5-12 hours to obtain the antibacterial ceramic glaze, wherein the fineness of the ball-milling slurry is that a specific gravity cup passes through a 325-mesh sieve, the sieve residue is 0.5-0.8%, and the flow rate is 30 ~50 seconds.

[0042] After adding the antibacterial agent and the conventional ceramic glaze and mixing evenly, then adding the suspending agent and the debonding agent to improve the mixing uniformity of the slurry, so that the suspending agent and the degumming agent can better play the role of improving the dispersion uniformity of the antibacterial agent Effect, limit the fineness...

Abstract

The invention relates to the technical field of architectural ceramics, and in particular, relates to antibacterial ceramic glaze, and a preparation method and an application thereof. The antibacterial ceramic glaze is composed of the following raw material components: a ceramic glaze material, an antibacterial agent, a suspending agent and a peptizing agent, wherein the antibacterial agent is a mixture of nano zirconium silicate loaded silver and nano zinc oxide, and the addition amount of the nano zirconium silicate loaded silver is 2-6% and the addition amount of the nano zinc oxide is 0.05-2% according to the weight percentage of the dry weight of the ceramic glaze material; the suspending agent is a mixture of low-viscosity sodium carboxymethyl cellulose and medium-viscosity sodium carboxymethyl cellulose; the peptizing agent is one of sodium tripolyphosphate or sodium metasilicate. The invention aims to provide the antibacterial ceramic glaze, and the preparation method and the application thereof; the prepared ceramic glaze can realize uniform dispersion of an antibacterial agent in the ceramic tile surface glaze, and has efficient sterilization and bacteriostasis effects and stable sustainable sterilization effect.

Description

technical field [0001] The invention relates to the technical field of architectural ceramics, in particular to an antibacterial ceramic glaze and its preparation method and application. Background technique [0002] At present, the competition of architectural ceramics is becoming increasingly fierce. In order to continuously expand the market coverage, while reducing production costs and improving product designs, more emphasis is placed on improving the functionality and technical content of products. These properties greatly increase the added value of products, thereby strengthening products. competitiveness. At present, with the improvement of people's living standards, people have put forward higher requirements on the living environment, and how to prevent pathogenic bacteria from invading the human body is particularly urgent. As ceramic tiles commonly used in people's living rooms, there will always be some dead spots for pollution and bacterial growth, especially...
