Description
Technical Field
The invention relates to an environment-friendly coating for an inner wall, in particular to a novel inner wall coating which is efficient and environment-friendly and can excite to generate negative oxygen ions.
Background
The atmosphere is a gas mixture composed of a plurality of molecules such as oxygen, nitrogen, carbon dioxide, water vapor and the like, the molecules are composed of atoms, the atoms are composed of atomic nuclei with positive charges and orbital electrons with negative charges, and the positive charges and the negative charges are equal. When air molecules are influenced by external conditions, such as cosmic rays, high-energy light beams, strong electromagnetic waves, free electrons, radioactive rays and other energy field conduction factors, or mechanical energy transmission generated along with changes of environmental conditions such as sea waves, waterfalls, rainstorms and the like, outer-layer electrons of atoms in certain components in the surrounding air can be excited, and the outer-layer electrons can be excited to separate from the original orbit and become free electrons. Atoms and molecules that lose electrons are positively charged, a process known as ionization of air. The free electrons can be combined with other neutral molecules, so that gas molecules with redundant electrons are negatively charged to form air negative ions, namely negative ions for short; and the gas molecules that lose electrons become positive ions. Oxygen and carbon dioxide have strong capacity of capturing free electrons, the content of oxygen in air exceeds 20%, and the content of carbon dioxide in air is only 0.03%, so most of the free electrons in air are captured by oxygen to form negative oxygen ions, and the negative oxygen ions become main components after air ionization. And is thus conventionally referred to as "negative oxygen ion".
Negative oxygen ions are called "vitamins in the air" and "longevity elements". It mainly influences the physiological activities of human body through the nervous system and blood circulation system of human body. The negative oxygen ions can strengthen the inhibition process of the cerebral cortex of a human and have the function of adjusting the cerebral cortex, thereby playing the roles of calming, hypnotizing and lowering blood pressure; after the negative oxygen ions enter the respiratory tract of the human body, the smooth muscle of the bronchus can be relaxed, and the spasm of the bronchus can be relieved; the negative oxygen ions enter the blood of human body, so that the sedimentation rate of erythrocyte is slowed, the coagulation time is prolonged, the content of erythrocyte and blood calcium is increased, the content of leucocyte, blood calcium and blood sugar is reduced, and the content of lactic acid in fatigue muscle is reduced. The negative oxygen ions can enhance the oxidation process of human tissues such as kidney, liver, brain, etc., wherein the brain tissue is most sensitive to the negative oxygen ions. The immunity can be enhanced by carrying out the cultivation under the condition that the content of the negative oxygen ions in the air is more than 1000/cm. The world health organization stipulates that the standard concentration of negative oxygen ions in fresh air is not less than 1000 and 1500 per cubic centimeter of air. The negative oxygen ions can effectively settle suspensible particulate matters in the air, and the professor Linjinming of Qinghua university indicates that the suspensible particulate matters in the air settle at the efficiency of 98% in 24 hours when the concentration of the negative ions reaches 20000/CM (carbon monoxide/carbon dioxide) in the book, and the negative oxygen ions are attached to carriers with smaller particle sizes, so that the higher the concentration is, the better the purification effect is. The negative oxygen ions can decompose hydrocarbon connecting chains in the formaldehyde to quickly decompose the carbon dioxide and water, which is the safest and effective formaldehyde removal method at present. Simultaneously, has the functions of bacteriostasis, peculiar smell removal, disinfection and purification in the air.
The generation mode of negative oxygen ions in the air is natural or artificial. One of the naturally occurring ways is to ionize the air by using the self electrostatic field of the natural materials, so that the electrons excited out of the orbit can float between water and oxygen molecules, and the oxygen molecules are converted into negative oxygen ions. In order to increase the concentration of negative oxygen ions, high-voltage corona is additionally utilized to prepare a negative oxygen ion generator, and one is to utilize composite minerals to prepare a negative oxygen ion excitation material. The negative oxygen ion coating is a functional coating formed by adding a negative ion excitation material. The human beings artificially synthesize or proportion the composite minerals to prepare the negative ion excitation material by utilizing the principle of generating negative oxygen ions in the nature. In the prior art, tourmaline powder and lanthanide or rare earth elements are used for realizing the function. The proportion of the rare earth elements greatly exceeds that of tourmaline powder. At present, the academic circles are controversial about whether the rare earth generates negative ions under the excitation function or the tourmaline generates negative ions under the relevant excitation. The rare earth metal ore is not a single metal ore, and not all rare earth elements can generate the same electron transition effect on air excitation energy. Modern theoretical researches prove that the addition of the components of the actinide metal oxide has the effect of improving the concentration of negative oxygen ions in the air. Actually, the excitation amount of negative oxygen ions in the air is increased, but more radiation is generated at the same time, so that the emission amount exceeds the standard. The method is detected according to the standard of 'limit of radioactive nuclide of the building material GB 6566-2010', and the internal irradiation index exceeds the standard, so that the method has harm to human bodies. The prior art is always a technical key to be solved urgently.
