2. Description of the Related Art In general, products made of glass are excellent in processing, strength, and appearance, and therefore, bottles for drinks such as juice and beer, containers for storing chemicals, cups, window glasses, etc. Is widely used in various fields.

Generally, glass products cannot be used if they are cracked or chipped. Therefore, they have been disposed of as industrial waste or dissolved at a high temperature and reused as a raw material for glass products.

Further, glass bottles of beer, sake, etc. have been subjected to high-temperature sterilization or disinfection after use, and have been repeatedly used again. In addition, since a glass container for storing a medicine used in a hospital or the like cannot be reused, a specialist trader has collected it and disposed of it specially.

[0005]

However, a great deal of cost and equipment were required to melt a glass product that could not be used at a high temperature and reuse it as a raw material for the glass product. Disposal as industrial waste is
This not only has a negative impact on the environment, but also results in a waste of limited resources. Therefore, disposal of glass products has been regarded as a major environmental problem in Japan, where the land area is small.

[0006] In addition, even if glass bottles for beverages are repeatedly recycled, the bottles are cracked or the edges are chipped, making it impossible to reuse the bottles and eventually being discarded as industrial waste. Become. Also, glass containers for storing chemicals have been disposed of as industrial waste by various means.

SUMMARY OF THE INVENTION In view of the above, the present invention uses a glass product that cannot be reused as a main raw material for manufacturing a phosphorescent body, thereby reducing manufacturing costs and reusing resources. Another object of the present invention is to provide a method for manufacturing a phosphorescent body using glass powder particles capable of realizing improvement of the global environment.

[0008]

According to the present invention, in order to achieve the above object, a phosphorescent raw material containing toluene and xylene is mixed with glass powder particles, and then a cementing agent is added to the mixture to accumulate phosphorescent light. A body is formed and the phosphor is dried and then baked.

[0009] A bonding agent containing Pbo and SiO ² as main components is added to the mixture.

[0010] A bonding agent containing Si, Na and Ca as main components is added to the mixture.

[0011] With the above configuration, the production cost is reduced by using glassware discarded as industrial waste as the main raw material for producing the phosphorescent material, and at the same time, limited resources are reused and the global environment is reduced. Improvements can be realized.

Further, the phosphorescent body produced by the above method is
It absorbs natural light during daytime and light energy from lighting, stores light, and can emit light naturally even in darkness. For this reason, by using it on the center line of a road, a sidewalk, the periphery of a bridge, or the like, the safety of traffic at night is improved. In addition, when used for a wall surface or a signboard of a building, the surroundings can be illuminated at night without the need for lighting.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a method for producing a phosphorescent body using glass powder particles according to the present invention will be described. In addition,
The method of manufacturing a phosphorescent body using the glass powder particles of the present invention is a manufacturing method that the present inventors have studied diligently for many years, and found as a result of repeated experiments, and has not been developed so far.
A luminous body with many advantages could be completed.

In the method for producing a luminous body using the glass powder particles of the present invention, the glass used as a main raw material is, in particular, beer bottles that are disposed of in large quantities as industrial waste, empty bottles for beverages such as sake, It is preferable to use a glass container or the like for storing a medicine, but all glass products such as a glass and a window glass which cannot be reused can be used as raw materials.

A glass product as a main raw material is crushed by a crusher or the like to about 0.1 to 2.0 mm to form a powdery or particulate glass powder particle. Further, the size of the glass powder particles is not particularly limited as described above, and it is preferable to appropriately change the size in the purpose of use or the manufacturing process.

Next, a phosphorescent material containing toluene and xylene is mixed with the glass powder particles.

The luminous raw material is formed by mixing several kinds of well-known metal oxides and rare earths, and further mixing with a commercially available coloring agent. The phosphorescent material is sunlight, ultraviolet light,
Also, when illuminated by an electric light or the like, light energy can be absorbed and stored, and light can be naturally emitted even in darkness.

Toluene is one of aromatic hydrocarbons and is a colorless and transparent liquid having a chemical structure in which one hydrogen of benzene is substituted with a methyl group. In addition, xylene is obtained by replacing a hydrogen atom of benzene with a methyl group with an aromatic hydrocarbon.

Next, a bonding agent is added to a mixture formed by mixing the glass powder particles and the phosphorescent material to form a phosphorescent body.

As an example of the bonding agent added to the mixture,
It is preferable that Pbo (lead monoxide) and SiO ² (silicon dioxide) are the main components.

Another preferred example of the bonding agent is Si
(Silicon), Na (sodium) and Ca (calcium)
Is preferably a main component.

Also, according to the present experimental example, the compounding ratio of the luminous body produced by the above method is as follows: luminous raw material 20%, bonding agent 15%, glass powder 43%, glue 2%, water 20%
%. However, the composition ratio of the components is not particularly limited, and the luminance of the phosphor can be further improved by increasing the proportion of the phosphorescent material.

Finally, the liquid phosphorescent body produced by the above method is poured into a molding die and completely dried in a hot air chamber for about 12 hours. After drying, store the phosphor for about 800
C. for about 8 hours at a temperature of .degree.

[0024]

As described above, the method for producing a phosphorescent body using the glass powder particles of the present invention has the following effects by adopting the above-described structure.

The luminous body is manufactured by using glassware discarded as industrial waste as a main raw material, so that it is possible to reduce the production cost, to reuse resources and to improve the global environment.

Further, the manufactured phosphorescent body absorbs natural daylight and light energy of illumination to store light, and can emit light naturally even in darkness. Therefore, by using it on the center line of the road, the promenade, and the periphery of the bridge,
The safety of traffic at night is improved. In addition, when used for a wall surface or a signboard of a building, the surroundings can be illuminated at night without the need for lighting.

In the manufactured phosphor, if the phosphorescent power is reduced due to the adhesion of dirt, the phosphorescent power is restored by polishing the surface, so that the phosphorescent power can be maintained semipermanently.
