JPS6126634A - Luminescent sheet - Google Patents

Abstract

PURPOSE:To provide the titled sheet emitting light without stimulation with external energy, having excellent appearance and high durability, applicable easily, and suitable as a guiding label, etc., by adding a luminescent paint containing radioactive element to a vinyl resin, heating and melting the resin, and forming to a sheet. CONSTITUTION:(A) A definite amount of a vinyl resin material is added with (B) 10-15% luminescent paint containing radioactive element such as radium, thorium, etc., and the mixture is heated and molten in an oven to integrate the component B with the component A. The obtained resin composition is pressed and flattened with a roll to obtain the objective thin sheet.

Description

Detailed Description of the Invention (Field of Application of the Invention) The present invention is a luminescent sheet formed by adding and fusing a self-luminous paint to a vinyl resin material, which can be used in hospital corridors and emergency exits after lights are turned off at night. Luminous sheets can be cut into characters, figures, etc. suitable for the location, such as indoor passages and emergency exits of high-rise buildings where many trading companies are located, or hotels, telephone poles on narrow roads, kitchens and barns in homes, etc. They can be pasted as night-light signs to make it safer to pass after the lights are turned off at night, to speed up evacuation in case of an emergency, to prevent danger on the road, and to allow household chores to be done even when the lights are turned off in the event of a nighttime power outage. This relates to a luminous sheet made of aluminum.

(Prior art) Luminescent paints that have been used in the past are mainly fluorescent paints, which emit light when stimulated by external energy such as ultraviolet rays or radiation after being applied to a predetermined location and dried. There is no luminescence in the dark indoors without stimulation. Therefore, it is used for outdoor purposes, for example, to prevent danger at a construction site, letters such as ``No Trespassing'' or ``Danger'' are written on the gate wall and illuminated to alert passersby.
Alternatively, signs that attract attention are painted on the front and rear of the vehicle so that the presence of the vehicle can be recognized even from a distance.

However, in addition to fluorescent paints, self-luminous paints that emit light even without external stimulation can be used as paints that emit light in the darkness indoors after lights are turned off to improve traffic safety. Direct application of this paint not only makes the interior unsightly, but also has the disadvantage that the paint weathers and peels off over time, reducing its luminous power.

(Problems to be Solved by the Invention) In this way, conventionally used fluorescent paints cannot be used indoors after the lights are turned off at night because they do not have luminous power, and self-luminous paints cannot be applied directly indoors. This can make the room unsightly, so instead of coating and drying each time, whether indoors or outdoors, we form a thin luminescent sheet that acts as a light source, and then use the luminous sheet to create letters or figures. If the sign is cut out in advance and pasted at a predetermined location, the sign can be easily operated, is highly durable, and does not disturb the harmony of the room.

(Technical means) In order to solve the above technical problem, a self-luminous paint containing a radioactive element such as radium or thorium in a vinyl resin material with a constant t of 10 to 15% is added and heated and melted in a kiln to fuse the self-luminous paint to the vinyl resin material, and then the vinyl resin fusion product is rolled in a rolling mill to form a thin luminescent sheet (l).

(Function) This thin luminous sheet) 111 is flexible and strong like conventional vinyl sheets, so it can be attached to floors and walls, and it can be colored freely, giving it a beautiful appearance. If formed and used in a state enriched with light, it will emit light in darkness at night without stimulation of external energy such as ultraviolet rays or radiation, and can be used for surfaces other than traffic or danger signs.

(Effect) Uninvented Luminous Sheet) 111 emits light from the surface of the sheet, so the Luminous Sheet (l itself is replaced by the letter (2)
, or a figure (3) that is cut out and used, and the letter (2) or figure (3) emits light according to its shape, alerting each person to protect their own safety in necessary places. It is.

(Example) The luminous sheet (1) formed by technical means has a wide width,
Since it is a long thin sheet, it is cut into shapes according to the purpose of use, but depending on the character, the shape may be cut continuously as a whole, or it may be necessary to cut it separately. There are things that cannot be done. Characters (2) that can be cut in one piece can be used for temporary pasting, but characters (3) that must be cut separately must be assembled into the desired character after being cut. In this case, use a thin vinyl base (
4) Separated and cut letters (3) are neatly pasted on the upper surface and pasted in a predetermined place together with the base (4). The same applies to figures, integral figures (+1)
The temporarily pasted, separated and cut figure (6) is the base (
7) They are pasted in an orderly manner on the upper surface, and then pasted at a predetermined location together with the base (7).

Since the present invention is formed by fusing a self-luminous paint to a vinyl resin material, even if the top surface of the luminous sheet (1) is touched and rubbed, the self-luminous paint will separate and reduce the luminous power. Because it remains luminescent for a long time without causing any damage, it can be used for indoor guide signs or danger signs after the lights are turned off at night, as well as for floors and walls of buildings, small vehicles, etc. to provide comfort through luminescence. This is something that can be obtained.
