The present invention relates to the field of escape signs during fire and emergency situations, and more particularly relates to a kind of self luminous sign.
In the prior art, night-glowing signs are usually made by mixing and blending luminous powder into printing/spraying inks/paints, and then printing/spraying the required night glow logo on an ordinary baseboard. Alternatively, a luminous film or a luminous board is used as the baseboard, and the required logo is printed thereon. These are the relatively more common ways of making a luminous sign in the market. Since the luminous powder can emit a more gentle light by converting the lights being absorbed, a night-glowing sign can continue to illuminate in the dark or in case of emergency without relying on electricity to indicate an escape direction.
However, luminous powder is characterized by emitting highly bright light at the initial stage after absorbing lights, but the brightness reduces in a rapid speed, after a few minutes, brightness will be reduced down to a low level and from where the brightness continues to further reduce gradually. A luminous layer of an ordinary night-glowing sign is only about 100-500 um, wherein an amount of luminous powder is insufficient, and the stored energy is less. The sign is not bright enough in 10 minutes, 30 minutes or 60 minutes after an emergency situation. In order to illuminate with sufficient brightness, an ordinary night-glowing sign has to be coated with a thicker luminous layer, thereby increasing the production costs significantly. When the thickness is increased to 500 um, the brightness of the sign reaches an upper limit and cannot be continued to increase significantly.
In view of the aforesaid disadvantages now present in the prior art, the present invention is provided.
A self luminous sign, comprising an aluminum board, an aluminum frame and at least one luminous module; the luminous module is attached on the aluminum board, and the aluminum board is mounted to the aluminum frame; each luminous module comprises the following components: resins, luminous powder coated with silane coupling agent, antioxidants and UV absorbents in a mass percentage of 100: (30-300): (0.01-10): (0.01-10).
Preferably, the resins comprise at least one of the following: Phenolic resin, epoxy resin, melamine resin, unsaturated polyester resin and acrylic resin.
Preferably, the luminous powder is light-storing pigment powder formed by long-afterglow luminous powder made of aluminosilicates and coated with silane coupling agent.
Preferably, a surface of the aluminum board forming the self luminous sign is pretreated by plastic spray or white coating.
Preferably, the aluminum board has a thickness of 0.1-2 mm.
Preferably, each of the luminous modules is made according to the following steps: mixing and blending evenly all of the components of the luminous module to form a mixture, pouring the mixture into a mold of a heat press, heat pressing the mixture for 60-150 seconds at a temperature of 120-200° C. and a pressure of 100T-500T, thereby resulting in a cured and formed luminous module.
Preferably, a back side of each of the luminous modules is attached with double sided adhesive tapes, for example those manufactured by the 3M company.
The present invention has the advantages of high initial brightness and sufficiently bright afterglow.
The present invention is further described in detail below with reference to the figures and the following embodiments.
