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 multi-functional low-temperature ceramic inks such as antibacterial luminous

Abstract

The invention discloses an anti-bacterial luminous low-temperature ceramic ink for ink jet and a preparation method thereof. The preparation method comprises the following steps: A, mixing and grinding 25-38% of pigment, 0.5-5% of anti-bacterial compound, 1-5% of luminous compound, and 15-20% of drier of low-temperature frit; B, weighing 3-8% of a dispersant, 2-5% of a surface additive, 0.1-0.3% of a flatting agent, 0.3-0.8% of an antifoaming agent, 0.5-1% of a binding agent, and 0.08-0.1% of an anti-settling agent, adding a solvent into a homogenizer to disperse and grind, filtering, and obtaining an ink finished product. Compared with the current low-temperature ceramic ink, the manufactured low-temperature ceramic ink has the characteristics of scientific ingredients, and the low-temperature frit without the extremely toxic substances, such as lead and cadmium, is used so that the ceramic ink can guarantee the color development performance while the ceramic ink is fired in the low temperature. The luminous compound and anti-bacterial compound are rationally matched for the synergistic effect, so the ceramic ink also has the durable spectral anti-bacterial character, the pollution-preventing and self-cleaning functions and the luminous character, 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 an antibacterial luminous 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] Long afterglow luminescent materials are commonly known as luminous powder. There are unsaturated energy levels in their electronic structure. Under light conditions, photon energy is absorbed to make electrons undergo energy level transitions. In a darker environment, the energy absorbed by electrons will be released. Creates a fluorescent effect. At present, long-lasting l...
