Abstract

A kind of Ceramic Tiles with fluorescence falsification preventing mark of the utility model, the ceramics turn from top to bottom sequentially to be sequentially surface glass layer, phosphor powder layer, bottom glassy layer, ground glaze layer, bottom base layer.The phosphor powder layer is ZnO:Zn as fluorescent material.Ceramic Tiles provided by the utility model are radiated at ceramic tile surface with ultraviolet light in relatively darker environment, using ZnO:Zn as the material layer of fluorescence, can excite and green light in a relatively short period of time, can be clearly apparent the shadow of fluorescence coating setting pattern.

Description

One kind having fluorescence falsification preventing mark Ceramic Tiles

Technical field

The utility model relates to a kind of building ceramic tiles, especially with the Ceramic Tiles of fluorescence falsification preventing mark.

Background technique

Currently, well known building ceramic tiles are not no anti-false signs, the mold at the brick back side can only be leaned on to the identification of brand The trade mark of compacting.When tile laying on the ground after, be that can not differentiate ceramic product is which brand belonged to, tested to consumer It makes troubles when receiving finishing material, has also encouraged the bad conduct that material is played tricks.

Utility model content

The technical issues of the utility model is solved is providing a kind of Ceramic Tiles with fluorescence falsification preventing mark, the ceramics Brick can not only be in product export for examining the brand of product, and can be after Ceramic Tiles paving on the ground, can also be square Just the brand of product is identified.

Technological means used by the utility model is as described below.One kind having fluorescence falsification preventing mark Ceramic Tiles, feature It is, which turns from top to bottom to be sequentially surface glass layer, phosphor powder layer, bottom glassy layer, ground glaze layer, bottom base layer.

Technical effect caused by the utility model: Ceramic Tiles provided by the utility model, in relatively darker environment, It is radiated at ceramic tile surface with ultraviolet light, using ZnO:Zn as the material layer of fluorescence, can be excited and green light in a relatively short period of time, The shadow of fluorescence coating setting pattern can be clearly apparent.

Detailed description of the invention

Fig. 1 is the schematic diagram of product structure of the utility model.

Specific embodiment

As shown in Figure 1, first applying one layer of ground coat enamel, then spray layer of transparent glaze slip on green body, then printing one layer has trade mark The fluorescent powder of pattern, then one layer of transparent glaze slip of glaze is sprayed, after 1200 DEG C of firings in high-temperature roller kiln 50 minutes, formed by bottom base layer 1, ground glaze layer 2, the structure of bottom glassy layer 3, phosphor powder layer 4, surface glass layer 5 obtain the Ceramic Tiles with fluorescence falsification preventing mark.? In relatively darker environment, it is radiated at ceramic tile surface with ultraviolet light, contains the Ceramic Tiles using ZnO:Zn as phosphor layer, energy It excites and green light in a relatively short period of time, the shadow of fluorescence coating setting trade mark can be clearly apparent.Wherein, phosphor powder layer be by ZnO and ZnS is calcined under 900 DEG C of reducing atmospheres, restores Zn by chemical change, Zn diffuses into matrix under high temperature action The lattice of ZnO causes ZnO lattice to be distorted and ZnO:Zn fluorescent powder is made, and is raw material made from first pre-burning.It is glimmering with ZnO:Zn Light powder is as fluorescent material, the luminous ceramic glaze of production jaundice green light, and mechanism is depositing in the zno-based matter Zn of excess Local shallow energy level is being formd, is constituting donor level close to conduction band, at room temperature ejected electron to conduction band, interstitial atom has phase To fixed position, they form acceptor level close to top of valence band, and constitute the centre of luminescence.Wherein, ground glaze layer is cosmetic soil, main Play the buffer action with bottom base；Phosphor powder layer is the ZN luminescence mechanism using Zn as the green light of self-excitation, is by excessive Caused by Zn, excessive Zn is occupied, and plays micro- luminous effect；Bottom glassy layer 3 and surface glass layer 5 are free of organic substance, prevent Glaze blacks after glaze firing, and the effect of transparent glaze layer is protection fluorophor, improves the service life of phosphor powder layer.

The utility model fluorescence coating printed patterns texture can be transformed into the pattern and surface fluorescence layer of arbitrary shape The pattern-free effect of all standing, each falls within scope of protection of the utility model.
