Description
Technical Field
The invention belongs to the technical field of building material processing, relates to a ceramic tile glaze, and particularly relates to a ceramic tile glaze capable of continuously releasing negative oxygen ions, and a preparation method and application thereof.
Background
From the 80 s in the 20 th century, japanese scholars found that Kakita river water in Fuji mountain was hardly polluted for a long time, and found that local ores have permanent electrodes, and the ores should be developed rapidly in the aspect of environmental protection and health care, and respectively relate to infrared health care, electromagnetic shielding, water purification treatment, anion health care and the like. People have a higher pursuit for the home environment due to the health requirement, but at present, products such as ceramic tiles are widely applied to home decoration and the like, the problem that how to add negative ions to eliminate harmful gases such as formaldehyde and the like in a living room becomes thought of by people is solved, and then materials capable of releasing the negative ions are added to the ceramic tiles.
Classification of air negative ion generation:
1. the collision is divided into high-efficiency: the air is acted by external conditions such as an ionizing agent and the like to obtain enough energy, so that valence electrons at the periphery of atomic nuclei are separated from the constraint of the atomic nuclei and jump out of orbitals to become free electrons, and then the free electrons become negatively charged ions;
2. lenard effect (waterfall effect): the water drops peel off large water drops through external shearing force to form water mist, the water drops are broken and then the large water drops are positively charged, and the water mist taken away by air in the impacting process is negatively charged (temperature, dissolved impurities, impact speed and contact interface);
3. neutral media charge effect (negative ion purifier): the high-voltage electric field activates oxygen or oxide to generate negative ions and ozone, which is harmful to body health;
4. pyroelectric effect and piezoelectric effect: due to the asymmetry of crystal structures of some natural ores, two atoms with high charges are arranged on a crystal lattice to be obviously dislocated, so that the two atoms generate thermoelectric and piezoelectric effects under the conditions of mechanical force action and temperature change of the crystals, namely, tiny changes of pressure and temperature can cause potential difference between the natural ores, adjacent air is ionized, hit electrons are separated from the constraint of atomic nuclei, and the hit electrons are easily attached to adjacent water and oxygen molecules and become air anions.
The method of spraying high-energy ionized water after printing adopted in the market at present generates negative ions, and the concentration of the ionized water is limited due to saturation. The amount and durability of the generated negative ions are difficult to guarantee.
In order to increase negative oxygen ions in ceramic tiles and eliminate the effect of harmful gases such as formaldehyde on human beings, researchers have thought to add components that generate negative oxygen ions to the ceramic. The tourmaline micro powder is added in the components mostly, the problem of poor glaze quality is caused by the excessive addition amount required for keeping the effect, and meanwhile, the generated negative ion effect is general, and the quantity of the negative ions is difficult to increase.
CN 104829133A discloses a negative ion ceramic glaze and a method for preparing a negative ion ceramic tile by using the same, wherein the negative ion ceramic glaze comprises the following components in percentage by weight: 15-55% of kaolin, 15-35% of stalanite, 5-10% of nano titanium dioxide, 5-15% of nano magnesium tourmaline powder, 20-40% of nano lithium tourmaline powder, 5-12% of praseodymium oxide and water: and (4) the balance. According to the patent, the negative ion effect is generated by adding the nano-magnesium tourmaline powder, the nano-titanium dioxide, the praseodymium oxide and the nano-lithium tourmaline powder, the specific gravity of the materials occupying the glaze is too large (both exceeding 30%), so that the performance of the glaze is poor, the generated negative ion effect is common, and the negative ion amount is difficult to further improve.
