る。TECHNICAL FIELD The present invention provides a reflective layer on an article by vapor deposition of aluminum, chrome plating, aluminum powder coating, etc., and a transparent resin layer on the reflective surface of the layer, and The present invention relates to an improvement in a method for producing a reflector by sprinkling glass beads in a single layer. According to the present invention, for an article having any shape (three-dimensional article), a reflector having a much higher front luminance than the conventional reflector can be manufactured.

できる。In detail, reflective sheets and reflective tapes are used for road accessories such as road signs, vehicles, lower poles and railroad crossings to ensure the safety and smoothness of traffic on roads, tracks, and tunnels. It is used for safety signs and safety hats used in construction, factories, mines, construction work and other work (JIS Z 9105 and JIS M 70).

Also, it can be used in various fields such as molded products, sheet metal products and pressed products such as audio, television and communication fields, bicycles, motorcycles, automobiles and other parts, and sports fields and marine fields. Furthermore, according to the present invention, it is possible to attach to a curved or curved material that cannot be attached with a conventional reflection sheet or reflection tape.

で、再度貼付しようとすればすぐに破れる。Conventional technology According to the conventional technology, when a pressure-sensitive or thermocompression-bonding reflective sheet or reflective tape is mounted on an article, the mounting work is performed using a hand-bonded or vacuum thermocompression-bonding applicator. There were restrictions on the size and shape of the article. Also,
The conventional sheet cannot be re-attached once it has been attached, and it will tear immediately if it is attached again.

Although it is possible to manufacture a reflector, the glass beads are piled up in 2-3 layers to deteriorate the light reflection efficiency, and for those having a three-dimensional shape, when the glass beads are scattered,
There are many inefficient spraying methods such as spraying by hand, spraying, and sieving, and a lot of beads are attached depending on the drying time of the resin, and in the semi-dry state, The beads may or may not adhere, resulting in inhomogeneous reflections. In particular, in the case of a three-dimensionally shaped article or a long article, the glass beads cannot be sprayed in a short time, and the tendency of inhomogeneity is strong. Further, the glass beads cannot be sprayed on the front surface and the back surface at the same time, so that the sufficient effect cannot be obtained from an economical point of view.
そして従来は、反射輝度を上げる検討は行われず、正面
輝度は白色の場合１０ｃｄ／m2以下の値がほとんどで、
角度特性はほとんどない状態であった。Conventionally, no consideration has been given to increasing the reflection brightness, and most of the front brightness is 10 cd / m 2 or less in the case of white,
There was almost no angle characteristic.
発明が解決しようとする問題点 本発明は、反射輝度の高い反射物を得るための改良製造

なかった分野においても充分に使用できるようなすぐれ
た反射物が製造できる。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The present invention provides an improved manufacturing method for obtaining a reflector having high reflection brightness, and is therefore excellent enough to be used even in a field where conventional reflectors cannot be satisfied. Reflective objects can be manufactured.
従来の反射シートおよび反射テープは交通と安全に関す

美観を必要とする分野でも使用できるようになった。The reflector obtained by the method of the present invention can be used from a field requiring very high frontal brightness to a field requiring angular characteristics, and durability is improved by selecting an appropriate surface resin and thick film coating. Also, when a thick coating film is formed, it gives a high-class feeling like tiles and enamel,
It can now be used in fields that require aesthetics.

本発明によれば、適切な表面樹脂の選択を行えば、耐久
性を向上させることが可能である。Furthermore, according to the method of the present invention, it is possible to manufacture a reflector such as an interior / exterior article used for a steel plate or an iron plate. Even if a conventional reflection sheet is pasted on a conventional interior / exterior article, it does not look aesthetically or feel heavy, and it is not possible to past a conventional pressure-sensitive type or pressure-bonded type (possibly hand-attached) reflection sheet. When it is used as an exterior article, it cannot endure a long service life and is likely to cause chalking (whitening).
According to the present invention, durability can be improved by selecting an appropriate surface resin.

るが、乱反射面が多くなり角度特性が上昇する。According to the present invention, when high frontal brightness is required, the particle size range of the glass beads is 75 to 82 μm, and the distance between the glass beads and the metallic reflection layer is 30 to 40 μm. To do. In addition, in order to improve the angle characteristic, the surface roughness of the reflecting surface should be 1
0 to 15 μm. Also, when making a reflecting surface of a long object such as a long steel plate, if the reflecting layer is made of aluminum powder paint, the reflection brightness will be about 1/3 that of aluminum vapor deposition, but there will be many irregular reflecting surfaces and the angle The characteristics increase.

Even if there are all beads can be coated. An example of the air flow type glass bead coating device is shown in FIG. Turn on the power supply (6) to operate the compressor (1) to produce compressed air, store the air in the air storage tank (4), and blow it out through the pressure diffusion plate (2) so as to have a uniform pressure distribution. The glass beads (3) are thereby brought into a uniformly fluidized state within the area surrounded by the iron frame (5), and the article to be processed is put therein, and the article is immersed and coated.

落下散布方式で行う場合とについて、比較検討した。Example 1 Using glass beads having a refractive index (Nd) of 2.18 to 2.19 and a particle size of 53 to 63 μm, it was tested whether the glass beads were aligned in a single layer on the transparent resin layer. That is, a comparison was made between the case where the glass beads are scattered by using the air-flow type glass bead coating device according to the present invention and the case where the conventional glass bead drop scattering method is used.

コーテイングした。The reflector shown in FIG. 1 was manufactured by the following method. Two pieces of 30 cm square ABS resin were used as the base material, that is, the base (7), and after the surface was washed with a cleaning agent, urethane resin was applied and dried at 70 ° C. to form a transparent adhesive resin layer (8). After that, aluminum vapor deposition is performed to form a reflective layer (9), and after the transparent resin is applied, the transparent resin layer (1
The glass beads (3) were coated while 0) still contained the solvent.

ま固着し、第５図に記載のごとくガラスビーズが２−３
層に積み重なり、当然、反射輝度が低下する。As shown in FIG. 4, in the method of the present invention, since the glass beads (3) are constantly in fluid contact during coating, unnecessary glass beads do not adhere to the glass beads, and even if the glass beads temporarily become two layers, It was clarified that all the glass beads of the layer were detached and the glass beads (3) surely adhered to one layer. On the other hand, since the conventional drop-dispersion method has no flow force, once the glass beads (3) are attached, they are fixed as they are, and as shown in FIG.
Stacked in layers, of course the reflected brightness is reduced.

The same operation as in Example 1 was performed except that the width was narrowed to 2 μm. As a comparison, a conventional glass bead drop spraying method was also used. Table 1 shows the reflection brightness of the obtained reflector. The color is white and transparent, and the measurement is J
It was performed according to the method defined in IS Z 9117.

As a result, it was confirmed that the reflection brightness was significantly improved and exceeded the second-class reflection performance specified by JIS Z 9117.

2 μm or 45 to 63 μm or 63 to 75 μm, and in order to improve the angle characteristics, the reflecting surface (12) is polished with an abrasive (corresponding to No. 2000 mesh) as shown in FIG. 10 to 15 μm, the focal length extends beyond the glass beads so that the focal point matches at the reflecting surface.

All of the glass beads were sprayed by the air flow spraying method. The method for measuring the reflection brightness is the same as that in the second embodiment. The color tone was white.
