Description

Rare earth ceramic self-luminous safety signboard

Technical Field

The utility model relates to a safety signboard, more specifically say, especially relate to a tombarthite pottery self-luminous safety signboard.

Background

Safety sign tablet/safety sign tablet is the sign that sets up for the safety consideration to reduce the potential safety hazard. Seen in large doorways outside the plant, inside the plant, and on roads. At present, the main base material of the safety signboard is PVC or aluminum plate, the shape of the main base material is changeable, the safety signboard can be provided with an inner chamber for installing various circuits and controllers, and is mostly used indoors, and a light source is generally arranged in the safety signboard. The latter is often used outdoors and matched with a reflective film, a self-luminous material and the like, but because the bonding property of the aluminum plate and the self-luminous material is poor, the problem that the self-luminous material layer falls off is very easy to occur especially in the environment of outdoor high temperature or frequent contact and friction of road surfaces, and the service life is short and unstable.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the not enough of above-mentioned prior art, provide a simple structure, stable in use and respond well tombarthite ceramic self-luminous safety sign board.

The technical scheme of the utility model is realized like this: a rare earth ceramic self-luminous safety signboard comprises a body, wherein the body comprises a ceramic substrate, a safety sign filling groove is formed in the surface of the outer end of the ceramic substrate, and a rare earth long afterglow material layer is filled in the safety sign filling groove; and a wear-resistant layer is arranged on the outer end surface of the ceramic substrate.

In the above-mentioned rare earth ceramic self-luminous safety signboard, the rare earth long afterglow material layer is located between the wear-resistant layer and the ceramic substrate.

In the above-mentioned rare earth ceramic self-luminous safety signboard, the outer end surface of the ceramic substrate is provided with a luminous or non-luminous decorative pattern layer.

The utility model adopts the above structure after, fill the safety sign filling inslot of predetermineeing on ceramic substrate through with tombarthite long afterglow material layer, form effectual self-luminous sign, and ceramic substrate has intensity height, with low costs, long service life's advantage, and tombarthite long afterglow material has advantages such as luminous luminance, afterglow time are long. Simultaneously, hold fixed tombarthite long afterglow material layer through the cell body structure, the trilateral contact surface that can show promotion ceramic substrate and tombarthite long afterglow material of cell body to the ceramic inslot wall that does not glaze is coarser, makes tombarthite long afterglow material combine very firm with ceramic substrate, does not have the problem that drops completely. Further, through setting up the wearing layer that has waterproof, fire behavior for the life of product further improves, this signboard, can be general in indoor outer, and need not dispose the light source, has very good market prospect.

The present invention will be described in further detail with reference to the following examples, which are not intended to limit the invention.

Fig. 1 is a schematic structural diagram of embodiment 1 of the present invention;

FIG. 2 is a schematic cross-sectional view at AA in FIG. 1;

fig. 3 is a schematic structural diagram of embodiment 2 of the present invention.

In the figure: 1. a body; 2. a ceramic substrate; 3. the security mark fills the slot; 4. a rare earth long afterglow material layer; 5. a wear layer; 6. and decorating the pattern layer.

Detailed Description

Example 1

Referring to fig. 1, the utility model discloses a rare earth ceramic self-luminous safety signboard, including body 1, body 1 includes ceramic substrate 2, and ceramic substrate in this embodiment adopts static pressure technology to press into the body of predetermined shape according to the demand at first, makes various luminous or non-luminous decorative pattern layer 6 on the body, like blue and white porcelain pattern etc. can embody the element of the peculiar culture tradition of china, has better decorative effect. Then fired at 1200-1500 degrees. This step may be a single firing step or may be a two-step firing step. Meanwhile, the ceramic substrate can adopt other preparation methods and decorative pattern layers which are conventional in the field, and can also be formed by adopting other conventional methods in the field according to the actual situation. This is not the technical point to be protected by the present invention, and will not be described herein.

A safety mark filling groove 3 is formed on the surface of the outer end of the ceramic substrate 2, and a rare earth long afterglow material layer 4 is filled in the safety mark filling groove 3; the rare earth long afterglow luminescent material layer is made of alkaline earth rare earth aluminate long afterglow luminescent material such as yellow green light SrAl₂O₄:Eu²⁺，Dy³⁺Sr of blue-green light₄Al₁₄O₂₅:Eu²⁺，Dy³⁺Violet light CaAl₂O₄:Eu²⁺，Nd³⁺Rare earth silicate long afterglow material Sr₂MgSi₂O₇:Eu²⁺,Dy³⁺Red Y₂O₂S：Eu³⁺，Ti⁴⁺，Mg²⁺、CaS：Eu²⁺，Sm³⁺And mixing the epoxy resin, MMA resin or polyacrylic acid resin according to the solid content of 5-80%. The mixture is filled in a safety mark filling groove to form a self-luminous layer, and the 1 minute afterglow brightness of the mixture is tested>4000mcd/m²1 hour afterglow luminance>200mcd/m²Time of visual observation>More than 30.

A wear-resistant layer 5 is provided on the outer end surface of the ceramic substrate 2. Preferably, the rare earth long afterglow material layer 4 is positioned between the wear resistant layer 5 and the ceramic substrate 2. Namely, the wear-resistant layer is sprayed on the whole outer end surface of the ceramic substrate, and the ceramic substrate and the rare earth long residual material layer which participate in contact are protected. Preferably, the wear-resistant layer is a wear-resistant, fireproof and waterproof protective layer formed by high polymer resin. The service life of the product can be effectively prolonged.

Compared with the domestic existing safety identification product, the method has the following advantages:

firstly, the solar building does not depend on an external power supply, and has important significance for safe emergency escape of the building after the solar light and the lamplight are absorbed and can continuously emit light for 12 hours at night.

Secondly, the ceramic fired by isostatic pressing and high temperature is used as a substrate, so that the ceramic has the advantages of high strength, low cost, long service life and the like, and the maintenance cost is extremely low.

Compared with the existing noctilucent marks on the ground of subways or buildings, the noctilucent marks are often replaced again after half a year, and the noctilucent coatings are poor in metal bonding force and easy to fall off.

And thirdly, the combination of the Chinese specific culture elements and the safe fire-fighting product is adopted for the first time internationally, so that the method has important significance for popularizing the Chinese elements, improving the product appreciation and the like.

The safety signboard shown in the embodiment is a signboard for marking the direction of an outlet, can be used in indoor and outdoor environments, and has the advantages of low cost and long service life.

Example 2

Referring to fig. 2, the self-luminous safety signboard made of rare earth ceramic of the present invention has the same structure as that of embodiment 1, and is different in the content of the specific mark, which is an arrow mark indicating an evacuation channel.

The above embodiment is the preferred embodiment of the present invention, which is only used to facilitate the explanation of the present invention, it is not right to the present invention, which makes the restriction on any form, and any person who knows commonly in the technical field can use the present invention to make the equivalent embodiment of local change or modification without departing from the technical features of the present invention.
