Description

Detailed Description of the Invention

  The present invention relates to a display structure that can be used without any trouble even in a high-temperature environment such as a fire, and further to a method for manufacturing the same.

  For example, various displays for evacuation guidance in the event of a fire are displayed on the corridor of a hotel or inn. Such a display is usually made of plastics, and there are various forms such as a display on a panel, a display unit integrated with a lighting fixture, and the like.

Problems to be solved by the invention

  However, in the case of the display body as described above, in the event of a fire, since it is inferior in fire resistance and heat resistance, it may be easily deteriorated and damaged, and the evacuation guidance function may not be sufficiently performed. Therefore, in place of plastics, heat-resistant metal or glass is also used. In this case, however, the display content itself due to surface printing or the like is deteriorated and damaged, and a sufficient evacuation guiding function is not achieved.

  The present invention has been made in view of the above points, and an object thereof is to provide a display structure in which a display function is favorably maintained even in a high temperature environment such as a fire. Furthermore, the manufacturing method is provided.

Means for solving the problem

  In the invention of claim 1, the display structure is configured such that a display body made of an inorganic material is embedded and fixed in a glass body, and the display body is visually recognized from the outside.

  According to the above configuration, since the entire display structure is made of glass, it has excellent fire resistance, heat resistance and chemical resistance, and since the embedded display body is made of an inorganic material, this display body is also fire resistant and heat resistant. Excellent chemical resistance. Therefore, this display structure exhibits a display function well without deterioration or damage even in a high temperature environment such as a fire, and can be used for many years. The display structure has an appropriate shape and is used to perform an appropriate display.

  The display structure of the invention of claim 1 is, for example, the step of forming the display unit by printing on the surface of the glass plate of the invention of claim 2 so as to cover the display unit with glass flakes on the glass plate. It is obtained by a manufacturing method comprising a step of laying and a step of fixing the glass flakes laid on the surface of the glass plate by heating and melting, and then incinerating and removing the organic material of the display portion by the heat. .

  As the glass plate, an inorganic material such as soda glass, quartz glass, or crystallized glass is used. By using quartz glass or crystallized glass, a glass having superior fire resistance and heat resistance can be obtained. As the printing paint for the display section, a mixture of a pigment made of an inorganic material and an organic binder is used. If a phosphorescent pigment is used as the pigment, a display structure in which the display body emits light in a dark place can be obtained. As the glass flakes, those having the same components as the glass plate to be used are used, and those having a particle size of 1 mm or less are used. By using glass flakes having a small particle size, the gap density of each particle of the glass flakes is increased, and discharge of waste gas to the outside during incineration of the organic binder is facilitated. The heat melting is performed at a temperature of 600 ° C. to 1200 ° C. This temperature range is a range in which the glass flakes can be melted and the organic binder in the display portion can be removed by incineration (300 ° C. or more).

  FIG. 1 is an external perspective view of a glass display structure of the present invention, and FIG. 2 is a cross-sectional view. The display structure 1 is configured by embedding a display body 7 made of an inorganic phosphorescent pigment in a flat glass body 5.

  Next, a method for manufacturing the display structure 1 will be described. First, as shown in FIG. 3, the display unit 4 is printed on the surface of a glass plate 3 made of soda glass using, for example, a paint in which an acrylic polyol as an organic binder and a phosphorescent pigment made of alumina oxide are mixed. .

  Next, as shown in FIG. 4, glass flakes 6 made of soda glass are laid on the glass plate 3 so as to cover the entire display unit 4. Next, it is heated in a heating furnace at a temperature of 700 ° C. for 1 minute to melt the glass flake 6 and fix it on the glass plate 3. At that time, the surface of the glass plate 3 is also slightly melted, and the melted glass flake 6 is integrated there.

  On the other hand, at the time of the above-described heating and melting, the acrylic polyol which is the organic binder of the display unit 4 is incinerated by the heat at around 300 ° C. which is the temperature raising process. The waste gas generated at this time is discharged to the outside through the particle gaps of the glass flakes 6 that are not yet melted. In this way, the display unit 4 is changed to a display body 7 made of only a phosphorescent pigment (actually containing some organic binder ash) and remains on the surface of the glass body 3.

  By the above manufacturing, a glass display structure 1 in which a display body 7 made of an inorganic material is embedded and fixed in a glass body 5 as shown in FIGS. 1 and 2 is obtained.

  Since the display structure 1 having the above structure is entirely made of glass, it has excellent fire resistance, heat resistance, and chemical resistance. Since the display body 7 is made of an inorganic material, the display body 7 is also made of fire resistance, heat resistance, and resistance. The excellent chemical properties make it possible to perform a display function for guidance of evacuation without deteriorating or damaging in a fire site, etc., and it has excellent durability and can be used for a long time.

  In particular, since the display body 7 is made of a phosphorescent pigment, the display of the display body 7 can be visually recognized by the radiation of the light energy accumulated in the phosphorescent pigment even when the light is turned off in the event of a fire, and thereby high safety performance is exhibited. The phosphorescent operation to the phosphorescent pigment is performed by receiving illumination light at the normal time. However, when the display structure 1 is used as a cover form of a lighting fixture, the light storage operation is more performed by receiving the light at the normal time. It is done efficiently.

The invention's effect

  According to the present invention, it is possible to obtain a highly safe display structure that is excellent in fire resistance, heat resistance, and chemical resistance, and that maintains a display function well even in a high-temperature environment such as a fire.
