Problems solved by technology

The negative ions induced by these methods in the air are not durable. As time goes by, the effect of generating negative ions will gradually decrease, or even be completely lost. What is more complicated is that some materials often use ultraviolet light for photocatalysis to activate the material. charged ions in the air to induce negative ions in the air

Abstract

The invention provides a crystalline glazed tile capable of durably producing negative ions and a preparation method thereof. In the invention, without significant change on a production process of glazed tiles in the prior art, the method mainly pays attention to formulas and compositions of a frit, a basic glaze, a nucleation agent and a surface glaze, fineness of the basic glaze and the nucleation agent, and optimization on a sintering process and the like, so that a large number of silver crystals, in the size of a rice grain, are formed on the surface of the glaze tiles, wherein the crystals emit a bright silver light under irradiation by oblique light or lamp light, while the glaze base surrounding the crystals are matte, so that the whole tile looks like a starry night. In addition,there are a plurality of photo-catalytic semiconductor microcrystalline mineral, which cannot be seen by naked eyes, such as SrTiO3 and CaO.TiO2, in the surface glaze, wherein the minerals can be reacted with oxygen in air to generate oxygen negative ions durably, quantity of the inductively generated negative ions in air reaching 538 / s*cm<2>. The product is a decorative material which integratesdecorative and artistic properties and health-functional effects.

Description

Technical field: [0001] The invention relates to the technical field of preparation of glazed tiles, in particular to a crystalline glazed tile which can continuously generate negative ions and a preparation method thereof. Background technique: [0002] The positive and negative ions in the air are divided into large, medium and small ions according to their mobility. Small air ions have a high speed of movement. They collide with each other in the atmosphere and continue to gather to form large or medium ions. Small ions or small ion clusters can enter the organism. Among them, the small negative oxygen ions or small ion clusters have good biological activities and are easy to penetrate the human blood-brain barrier and enter the human body to exert their biological effects. The negative oxygen ions in the air are referred to as negative ions, and are called "longevity element" or "air vitamin". Human health is also inseparable from negative ions. A large number of clinical pr...
