Inorganic light-accumulation luminous wall and floor tiles molded by one-time sintering and preparation method thereof

Abstract

The invention provides inorganic light-accumulation luminous wall and floor tiles molded by one-time sintering and a preparation method thereof. Each tile comprises a bottom material, a reflection layer arranged on the bottom material, a luminous layer arranged on the reflection layer, and a protective layer arranged on the luminous layer, wherein the bottom material is formed by burning argil andclay; the reflection layer is made of a non-transparent diffuse reflection material; in parts by weight, the diffuse reflection material is prepared from 3 to 5 parts of an oxide with high reflectivity and 95 to 97 parts of glass powder; the luminous layer is prepared from the following components in parts by weight: 10 to 60 parts of a long-persistence fluorescent material, 40 to 90 parts of high-temperature calcium-based glass powder and 0 to 1 part of a glaze pigment; by the introduction of a light reflection layer, the light output efficiency is improved; by the adoption of an inorganic material, the problems of corrosion and degradation caused by ultraviolet rays are avoided; by the adoption of the high-hardness layer on the surface for protection, the mechanical strength and the light output efficiency are improved; and by the adoption of the reflection layer, the excitation efficiency and the light output efficiency are improved. The method realizes continuous molding on one production line, one-step sintering molding is realized, the efficiency is high, the energy consumption is low, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of luminescent wall and floor tiles, in particular to an inorganic light-storing luminescent wall and floor tile formed by one-time sintering and a preparation method thereof. Background technique [0002] Long afterglow luminous materials are currently mainly used to make night warning signs. At present, long afterglow luminous powder is usually mixed with resin to form plates or other non-planar shapes by machining or coating. The biggest problem with resin-based luminous luminous materials is The problem of weather resistance, the destruction of the chemical bonds in the resin by ultraviolet light in sunlight directly leads to the yellowing, deterioration, and failure of the entire product, which reduces the luminous efficiency and service life of the product. Secondly, the mechanical strength is weak, and it is easy to form a large amount of Surface scratches affect the surface finish and cause dust accu...
