Ink for releasing negative ions and fabricating method thereof

Abstract

The invention relates to ink for releasing negative ions, which belongs to novel healthy environmental-friendly cultural goods for releasing negative ions and can permanently release the negative ions. The number of the released negative ions is more than 1000 / cm. The ink has the efficacy of removing harmful gases and peculiar smell, purifying air, resisting bacteria and inhibiting bacteria, radiating far infrared rays and resisting electromagnetic wave radiation and can improve the secretory function of the alveolus and the ventilation and the air exchange of the lung, improve the microcirculation, strengthen the immunity of a human body and resisting the bacteria, thereby being beneficial to the health and having better health care function. The developed and researched health environmental-friendly ink for releasing negative ions has higher scientific and economic values and important realistic meaning.

Description

Technical field: [0001] The invention belongs to the fields of stationery, printing, printing ink, chemical industry, health, environmental protection and the like. Background technique: [0002] Printing inks are generally divided into three types according to their composition, water-based ink, solvent ink, ink, as the name suggests, the system of water-based ink is water, this ink is environmentally friendly, solvent ink is made of xylene, isopropanol As a solvent, the solvent commonly used in ink is kerosene with a high boiling point. Obviously, the remaining two types have certain hazards. Ethanol, toluene, and other organic solvents are often used in printing inks. Although most of these organic solvents will be eliminated after drying, the remaining parts will still cause harm to the human body. In particular, printed matter with a larger inking area and a thicker ink layer has more residual solvents, and the toxic substances released during use pollute the air and e...

AI Technical Summary

Problems solved by technology

Organic solvents such as ethanol, toluene, etc. are often used in printing inks. Although most of these organic solvents will be eliminated after drying, the remaining parts will still cause harm to the human body.

Especially for printed matters with a large inking area and a thick ink layer, there are more residual solvents, and the toxic substances released during use pollute the air and endanger people's health

A major problem of ink pollution also lies in pigments. These pigments have very small particles and strong adsorption capacity. They contain heavy metal elements such as lead, chromium, cadmium, and mercury, all of which have certain toxicity.

In addition, a large amount of thinner containing benzene is used in printing, which is toxic and has a strong pungent smell. It is easy to pollute the air during use. Long-term inhalation will affect the central nervous system of the brain and cause great harm to human health.
