DISCLOSURE OF INVENTION Problems to be Solved by the Invention In the conventional example, a resin that cures at room temperature and pressure is of a degree that does not hinder the curing of the resin.
Since only 0.5 to 3 parts by weight of the luminescent coating is mixed, the problem is that the luminescent effect is not very good.

Further, since the resin containing the luminescent paint is loaded into the upper and lower molds for molding and then solidified, two molds are required at the upper and lower sides, resulting in a high production cost and complicated work. It was a problem.

Further, at room temperature and atmospheric pressure, the resin containing the luminescent coating is cured, so that a long curing time is required, resulting in poor productivity.

In view of such drawbacks, it is an object of the present invention to provide a method for manufacturing a light emitting patch and a light emitting patch which can obtain a sufficient light emitting effect in an extremely short time.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 1 to 5, a method for manufacturing a light emitting patch according to the present invention comprises the following steps.

First, the silicone resin 12 and the curing agent 14
And the powdery luminescent paint 16 are mixed to form the luminescent solvent 18 (see FIG. 3).

In this example, the mixed powdery luminescent paint 1
In order to improve the visibility of No. 6, the silicone resin 12 used is colorless and transparent.

Further, the powdery luminescent paint 16 may be any one as long as the luminescent color exhibits various colors.

The luminescent coating material 16 is made into a powder state in order to facilitate mixing with the silicone resin 12.

Therefore, the silicone resin 12 and the curing agent 1
4 and the powdery luminescent paint 16 can be easily mixed by a mixer having a rotary blade or manually with a mixer such as a spatula.

The weight fraction of the powdery luminous paint 16 is preferably 5 to 20 parts by weight with respect to the total amount of the luminous solvent 18.

Here, the weight fraction of the powdery luminous paint 16 is
The amount of 5 to 20 parts by weight with respect to the total amount of the luminescent solvent 18 means that if the amount is less than 5 parts by weight, the luminescent effect is not obtained and the product value is lost.
This is because the curing of the

The luminous solvent 18 is used as a mold 20 for a patch.
(Fig. 4).

The patch mold 20 of this embodiment is not a pair of upper and lower molds, but only one of them, as long as it has a recess 22 for a patch.

After placing the cloth 24 on the patch mold 20, the luminescent solvent 18 is welded and solidified on the surface of the cloth 24 via a high temperature pressure bonding device 25 such as a press.
(See Figure 5).

The welding temperature by the high temperature pressure bonding device 25 is preferably 80 to 140 degrees Celsius.

Here, the welding temperature is set to 80 degrees Celsius to 140 degrees Celsius.
When the temperature is less than 80 degrees Celsius, the curing speed of the luminescent solvent 18 is delayed, and when the temperature exceeds 140 degrees Celsius, the light emission of the luminescent paint 16 is hindered and the texture of the surface of the cloth 24 is impaired. Because.

The welding pressure is to improve the welding efficiency of the luminescent solvent 18 to the cloth 24 by applying a pressure higher than the normal pressure. The higher the welding pressure, the higher the welding efficiency, and the pressure is 2 to 8 atmospheres. Is desirable.

The dough 24 is placed in the high-temperature pressure bonding device 25, and the patch mold 20 filled with the luminous solvent 18 is placed on the dough 24, and then the luminous solvent 18 is applied to the surface of the dough 24. It is also possible to weld and solidify.

In this way, the light emitting patch with the three-dimensional pattern shown in FIGS. 1 and 2 is manufactured.

This light emitting patch is used by being attached to clothing, a bag, shoes, etc. via an adhesive or the like.

At this time, when the luminescent paint 16 in the luminescent solvent 18 stores sunlight, light from a fluorescent lamp or the like and moves it to a dark place, the luminescent paint 16 emits light to cause the luminescent patch to emit light.

Therefore, by wearing or carrying clothes, bags, shoes, etc. to which the light emitting patch is attached, for jogging at night, using a bicycle at night, going out at night, etc.,
The paint 16 emits the light of an automobile or the like running at night, and the light emitting patch emits light, which is extremely effective in preventing a traffic accident or the like.

Another method is shown in FIG.

In this example, instead of loading the luminous solvent 18 of the above method into the patch mold 20 and placing the dough 24 on the patch mold 20, then welding and solidifying the luminous solvent 18 is performed. The luminous solvent 18 on the surface of the cloth 24 in advance,
After being welded and solidified as a whole, it is die-cut into a predetermined shape by a patch die 26.

By using the punching die 26 having a large number of punching holes 28 corresponding to the shape of the light emitting patch which is a product, it is possible to form a large number of light emitting patches at one time and to sufficiently cope with mass production. You can

In both the examples, an adhesive layer is formed on the back surface of the cloth 24 in advance, and a release paper is attached to the surface of the adhesive layer to fabricate a light emitting patch.
It can be easily attached to a bag, shoes and the like.

In both examples, the silicone resin 12
Is transparent and colorless, but can be freely colored.

Further, in the present invention, the silicone resin 1
2 is used because it has excellent heat resistance, abrasion resistance, and compatibility with foreign matter.
It is self-evident that various resins similar to silicone can be used instead of.

According to the method for producing a light emitting patch according to the present invention, a light emitting solvent composed of a silicone resin, a curing agent, and a powdery light emitting paint is welded and solidified on the surface of a cloth at high temperature and high pressure. Therefore, the welding and solidification time of the luminescent solvent can be shortened, and the luminescent patch with a three-dimensional pattern can be manufactured in a short time, and the productivity can be improved.

Further, the luminescent solvent is welded and solidified on the surface of the cloth at a high temperature and a high pressure, and then the luminescent solvent is die-cut into a predetermined shape through a die for a patch, whereby the production of the luminescent patch is simplified. Therefore, a large number of light emitting patches can be formed at one time, and mass production can be sufficiently dealt with.

By setting the weight ratio of the powdery luminescent coating material in the luminescent solvent to 5 to 20 parts by weight, a sufficient luminescent effect which is a characteristic of the luminescent patch can be obtained.

By setting the welding and solidifying temperature of the luminescent solvent to the cloth to 80 to 140 degrees Celsius, the welding and solidifying time can be set to several minutes, and the productivity of the luminescent patch is further improved. You can
