Problems solved by technology

However, in order to reduce the temperature of the traditional low-temperature frit, a large amount of chemical substances containing lead and cadmium are used. Although the effect of reducing the melting temperature can be achieved, the chemical substances of lead and cadmium are highly toxic.
At the same time, there are few reports on the use of low-temperature frit to prepare functional low-temperature ceramic inks, such as antibacterial low-temperature ceramic inks. If antibacterial agents are simply added, the antibacterial stability will be weakened due to the high-temperature melting process and the problem of easy agglomeration of antibacterial agents. May even lose antibacterial effect

Abstract

Antibacterial low-temperature ceramic printing ink used for ceramic inkjet printing and a preparing method thereof are disclosed. The method includes A) a step of mixing 25-38% of pigment, 0.5-4% of an antibacterial composition and 15-20% of dry low-temperature frits and grinding, and B) a step of weighing 3-8% of a dispersant, 2-5% of a surfactant, 0.1-0.3% of a levelling agent, 0.3-0.8% of a defoaming agent, 0.5-1% of a binding agent, 0.08-0.1% of an anti-settling agent and a solvent, adding into a high-speed mixer, dispersing, grinding, vacuumizing, vibrating at a high speed and filtering to obtain a finished product of the printing ink. Compared with low-temperature ceramic printing ink at present, the antibacterial low-temperature ceramic printing ink is scientific in material matching, reasonable in preparation and stable in performance, and adopts the low-temperature frits free of lead, cadmium and other extremely toxic substances, and therefore the ceramic printing ink can maintain color development performance during low-temperature sintering, and bright-colored and sharp color development effects can be achieved. The ceramic printing ink has durable antibacterial characters and antifouling and self-cleaning functions so that the application range of the low-temperature ceramic printing ink is further broadened.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to an antibacterial low-temperature ceramic ink for ceramic inkjet printing and a preparation method thereof. Background technique [0002] Bacteria and mold, as pathogenic bacteria, are very harmful to humans, animals and plants, affecting people's health and even life-threatening, and bringing significant economic losses. Therefore, the research on antibacterial materials and their products has attracted people's attention day by day, and the demand for antibacterial products will constitute a huge market. [0003] Wall tiles, no matter for home interior decoration, industrial production or public places, how to make them have more functions related to people's health protection in addition to satisfying the appearance and practicality is also a benchmark for scientific researchers in the industry to follow the trend of the times and life and made thinking. [0004] In the exis...
