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...
