Glaze capable of releasing negative ion, preparation and use method thereof

Abstract

The invention discloses a glaze which can generate negative ion and is characterized in that: the prescription of the glaze also contains a stimulating material that can generate tourmaline microcrystalline structures and an energy transferring material. The main composing scope (proportion by weight) of the prescription of the glaze is as follows: SiO2: 40 percent to 70 percent, Al2O3: 5 percent to 15 percent, K2O+Na2O: 5 percent to 10 percent, CaO: 0.1 percent to 12 percent, MgO: 0.1 percent to 10 percent, ZnO: 0.1 percent to 10 percent, B2O3: 0.1 percent to 10 percent; the stimulating material: 0.1 percent to 10 percent and the energy transferring material: 0.1 percent to 10 percent. The preparation method of the invention comprises the following steps: first, fusion cakes is prepared; the materials of the prescription are mixed in mixture ratio and fused and then quenched rapidly to prepare into the fusion cakes; second, sintering is carried out after the fusion cakes are prepared; finally, finished products are obtained by grinding. The application method of the glaze is that: 2 percent to 15 percent of the glaze is added to a glaze of a building sanitary ceramics and goes through glaze application and then is sintered into glaze at 800 DEG C to 1300 DEG C. The glaze of the invention has the advantages of having good release effect of the negative ion, and being environmental-friendly, etc.

Description

technical field [0001] The invention relates to the technical field of glazes, in particular to a special negative ion-generating glaze and its preparation and application method. Background technique [0002] Because negative ions have good effects on the human body, there are currently many ways to introduce negative ions into people's living environment, such as the use of corona discharge and electron beam principles to manufacture negative ions. A method of supplying negative ions through a filter; however, negative ions produced by corona discharge also produce negative effects on the human body such as nitrogen oxides and ozone. The air filter that mixes tourmaline powder into resin fibers must force the air to pass through only a small amount of negative ion concentration, and it must be given the conditions of the hardware structure of the equipment to provide external stimulation of friction and physical stress. The concentration of negative ions produced by elect...

Problems solved by technology

Tourmaline will generate potential when the temperature increases. Among ferroelectric materials, tourmaline has pyroelectricity, but to achieve the purpose of releasing negative ions, it needs to be assisted by physical external stimuli, and the average particle size should be controlled at 1mm~ 5μm to ensure that the negative ion generation efficiency will not be deteriorated due to changes in the crystal structure and polarization phenomenon, so it is difficult for the negative ion performance of this pure mineral type product to play a role in environmental purification.

[0003] As for architectural sanitary ceramic glaze, if the powder obtained by processing natural tourmaline ore is used, its color is the inherent color of the ore, mostly gray or dark gray, except for the color appearance of glazed ceramic products. In addition, it is only possible to protect the tourmaline structure from decomposing during the firing process of the glaze under the conditions of specific glazes, and lose its negative ion release function, thus reducing the application of this aspect.

[0004] There is a Chinese patent with the publication number CN1386550A describing a kind of gray ultrafine tourmaline powder treated by a special process technology so that it is covered with a layer of white titanium dioxide to obtain a white tourmaline powder, but the preparation process of this material is complicated. The promotion and application of industrialization may also involve the problem of high cost; and during the high-temperature firing process, the white titanium dioxide coating is easy to interact with the glaze and lose its bleaching function, which will also affect the appearance of the finished architectural sanitary ceramics and the ability to release negative ions. influences

[0005] Also have publication number CN1769242A Chinese patent to utilize the synthetic method to prepare the ceramic material with negative ion emission function, though its whiteness can reach more than 60 degrees, but basically need on the application of high-temperature firing part for building sanitation ceramic glaze , and no special description
