Description

Detailed Description of the Invention

  The present invention relates to a phosphorescent sheet for disaster prevention, a manufacturing method thereof, a construction method, and a usage method. In particular, in order to prevent human disaster at the time of a disaster, the surrounding situation can be visually recognized and developed for the purpose of time and brightness that can be evacuated. It relates to a phosphorescent sheet.

  Conventionally, many studies using phosphorescent materials have been conducted. Most of the phosphorescent materials are made of sulfide. However, there is a hindrance to the human body by generating radioactivity in a small amount. Recently, instead of these, phosphorescent materials using oxides (ceramics) as a raw material have increased. However, the present situation is that there are few materials having functional effects for disaster prevention with short afterglow luminance and afterglow time.

Problems to be solved by the invention

  However, the above-described conventional phosphorescent products have inferior phosphorescence luminance and afterglow time, and the functional effect at the time of disaster prevention cannot be sufficiently obtained. For example, phosphorescent materials used for general public facilities such as subway premises, subway cars, underpasses, etc. are only evacuation guidance signs in the dark at the time of a disaster, and the surrounding area can not be seen, so the escape place is lost, just going right and left However, the current situation is that people's lives cannot be protected.

  An object of the present invention is to solve the above-described problems and to provide a phosphorescent sheet having a function of evacuating within a sufficient visual recognition time, a manufacturing method, a construction method, and a usage method thereof.

Means for solving the problem

  The phosphorescent sheet of the present invention is characterized by a phosphorescent sheet made of a mixture of retroreflective glass bead grains that transmit light into a heat-resistant transparent silicone agent and a ceramic phosphorescent material.

  1st invention of the phosphorescent sheet manufacturing method of this invention is 50-120 weight part for the particle diameters of 250-63um of retroreflective glass bead grains with respect to 100 weight part of heat-resistant transparent silicon materials, and ceramic phosphorescent material 10-100um. By mixing 50 to 120 parts by weight, light is transmitted through the entire surface of the phosphorescent sheet, thereby maximizing the amount of accumulated light.

  The second invention of the phosphorescent sheet manufacturing method of the present invention is characterized in that a V-groove is provided on the phosphorescent sheet surface and can be freely cut according to the purpose of use.

  The third invention of the phosphorescent sheet manufacturing method of the present invention is characterized in that a pressure-sensitive adhesive is applied to the back surface of the phosphorescent sheet, a plastic film is applied, and the film can be peeled off in use to strongly adhere to any substrate. is there.

  Moreover, the construction method of the phosphorescent sheet of the present invention is characterized in that the size can be cut from the V-groove according to the purpose of use, the plastic film can be peeled off and attached to any substrate.

  Furthermore, the method of use of the present invention is affixed to a portion with high illuminance of a lighting fixture to increase luminous intensity, and in the dark of a disaster lighting accident, the brightness that can be seen in the vicinity and the time that can be evacuated are lengthened to eliminate human injury. It is characterized by.

  Furthermore, the purpose of use of the present invention is a public object that is particularly used by many people. In general living and living spaces, especially in the event of a power outage due to a disaster, it is characterized by a phosphorescent sheet for disaster prevention that has been developed for the purpose of preventing and evacuating the surrounding situation, and the time and brightness to evacuate It is.

  The composition of the phosphorescent sheet of the present invention is composed of a mixture of 100 parts by weight of ceramic phosphorescent material 60 um and 100 parts by weight of retroreflective glass bead grains 212 to 106 um with respect to 100 parts by weight of heat-resistant transparent silicon.

  In the composition of the phosphorescent sheet of the present invention, it was found that the retroreflective glass bead particles that transmit light have a higher luminous intensity and afterglow luminance because they transmit light when the particle size is larger than that of the phosphorescent material.

When the initial afterglow luminance of the phosphorescent sheet of the present invention was measured, it was found that it was very bright as 29,240 mcd / m ^2, and the time in which the human could visually recognize the afterglow time was as long as 4 hours.

  When the afterglow luminance time-dependent change of the phosphorescent sheet of the present invention was measured with a Minolta LS-100, the following data was obtained.

Table 1

was gotten.

The phosphorescent sheet of the present invention was cut into a 100 m ² room, pasted near 40 fluorescent lamps, and turned off at night to confirm that surrounding objects could be seen and evacuated for more than 2 hours. It turns out that there is brightness that can be.

The invention's effect

  As is clear from the above description, according to the present invention, it has been found that by mixing retroreflective glass bead grains through which light is transmitted, the luminous intensity is increased with a small amount of luminous material, and the luminous time is increased. If there is an illuminator installed in the living space of human beings, the phosphorescent sheet of the present invention is attached to the periphery of the illuminator. I can protect my life.

  In addition, the phosphorescent sheet of the present invention can freely control the size and brightness according to the purpose of use and the equipment to be used, and can achieve a functional effect.

  Furthermore, the phosphorescent sheet of the present invention can be used indoors and outdoors, such as for nighttime outdoor warning signs and energy saving signboards, in addition to the disaster prevention described herein.
