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 frits to prepare functional low-temperature ceramic inks, such as photochromic and other multifunctional low-temperature ceramic inks.

Abstract

The invention discloses photochromic low-temperature ceramic ink for ink jetting and a preparation method thereof. The preparation method includes the following steps that A, dry materials of 25-38% of pigments, 0.5-5% of antimicrobial composite, 1-10% of photochromic composite and 15-20% of low-temperature frit are mixed and ground; B, 3-8% of dispersant, 2-5% of surfactant, 0.1-0.3% of flatting agent, 0.3-0.8% of defoamer, 0.5-1% of binding agent, 0.08-0.1% of anti-settling agent and a solvent are weighed, the materials are added into a high-speed stirrer for dispersive grinding, filtering is carried out, and the finished ink is obtained. Compared with existing low-temperature ceramic ink, the prepared low-temperature ceramic ink is scientific in burdening, the low-temperature frit not containing lead, cadmium and other extremely toxic substances is adopted, and therefore the color development performance of the ceramic ink can still be guaranteed during low-temperature sintering; by reasonably matching the photochromic composite and the antimicrobial composite, the photochromic composite and the antimicrobial composite coordinately act, the ceramic ink further has the durable spectrum antimicrobial characteristic, anti-fouling self-cleaning function and photochromic characteristic, and the application range of the low-temperature ceramic ink is further widened.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a photochromic low-temperature ceramic ink for inkjet 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] Photochromism refers to photochromism caused by different light sources and color changes caused by physical phenomena such as reflection, refraction and interference. Photochromic materials are divided into organic photochromic materials and inorganic photochromic materials, among which inorganic photochromic materials are less studied, mainly including transition metal oxides, metal h...
