Description
Technical Field
The invention relates to a coating, in particular to a coating capable of releasing negative ions.
Background
The significant influence of negative ions on human health, longevity and ecology is verified by experts in medical field at home and abroad through clinical practice. The modern science reveals the mysteries of bioelectricity, each cell of an organism is a microcell, the potential difference between the inside and the outside of the cell membrane is 50-90mv, and if the 'cell battery' cannot be sufficiently supplemented with electric charge, the electrical process of the organism is difficult to maintain continuously, so the normal activity of the organism is influenced, and aging and premature senility are generated.
The negative ions not only promote the synthesis and storage of vitamins in the human body, but also strengthen and activate the physiological activities of the human body, so the negative ions are also called as 'air vitamins', and the negative ions are considered to have very important influence on the life activities of the human body and other organisms like the vitamins of food, and people feel happy after thunderstorm and the negative ions in the air are increased. In the air-conditioned room, negative ions in the air almost completely disappear after being subjected to a series of air-conditioning purification treatments and a long ventilating duct, and people who stay in the air-conditioned room for a long time feel chest distress, dizziness, weakness, and decline in working efficiency and health condition, which are called as "air-conditioning syndrome". In the medical field, negative ions have been identified as an effective means for killing germs and purifying air. The mechanism is mainly that after the negative ions are combined with bacteria, the bacteria generate structural change or energy transfer, so that the bacteria die and finally sink to the ground. Medical research shows that the negatively charged particles in the air increase the oxygen content in the blood, are beneficial to blood oxygen transportation, absorption and utilization, and have the effects of promoting human metabolism, improving human immunity, enhancing human body muscle energy and regulating the function balance of the human body. According to examination, the negative ions have the effects of inhibiting, relieving and assisting in treating 7 systems of human bodies and nearly 30 diseases, and particularly have more obvious health-care effect on the human bodies.
The paint is commonly used for indoor decoration, and is coated on a wall body to fulfill the aim of beautifying the wall. The time that people stay indoors is far longer than the time outdoors, if the negative ions released by the coating are beneficial to human bodies but harmless, and the problem of air-conditioning diseases can be effectively solved.

The invention has the beneficial effects that:
according to the invention, the negative ions are added into the formula, so that the prepared coating can release the negative ions, purify air, and enable the air to be filled with the negative ions, so that the air is fresh, and the problem of air conditioning diseases can be effectively solved. The anion additive has wide source and low cost, can be added after being prepared into powder, and is simple and convenient to produce. And the addition of the anion additive can also serve as a part of filler, so that the use amount of the filler is reduced. The production cost is not increased too much compared with the traditional coating. And the active carbon in the coating can also be used as a carrier of the anion additive, so that the anion releasing effect of the anion additive is better.
