Description

[Detailed Description of the Invention] Conventionally, ornamental interior items and brooches have been produced in which inorganic design articles such as animal and plant insects, petals, ores, and corals are encapsulated in transparent glass or hard transparent synthetic resin moldings. Since the decorative articles encapsulated in the synthetic resin moldings have a small coefficient of thermal expansion, they do not expand or contract due to changes in temperature and do not cause crevices in the synthetic resin moldings. The inventor is
Text on the surface instead of a designed article.

Aluminum and copper that are afraid of shapes, patterns, colors, etc.

Display boards for various purposes such as brass are encapsulated in a hard transparent synthetic resin molded body, and we have prototyped a product that protects the metal display board from rainwater and has the effect of increasing the texture as well as the external design effect of the transparent body. When used as nameplates, various display boards for automobiles, etc., the internal metal display board has a relatively low coefficient of thermal expansion at normal temperatures of 40°C to below freezing when subjected to large changes due to outside air temperature. Due to its large size, due to its expansion and contraction, a
It has been found that it is not particularly suitable for outdoor use because it has the disadvantage of causing a large size.

The present invention solves these problems, and allows the transparent synthetic resin molded body to last for a long time without cracking due to the expansion and contraction of the metal material sealed inside, and without easily damaging the outer surface, even when used indoors as well as outdoors. This product provides a stable integrated product for display purposes, in which a metal workpiece is wrapped and bonded with an elastic transparent synthetic resin, and at least a part of the outer surface of the wrapped body is covered with a transparent hard synthetic resin molding. It comes together.

Next, the invention will be explained with reference to examples.

Metal products include three-dimensional metal design products such as cast dolls9
These are display boards for various circumferential speeds, which are either flat or uneven by finning, etc., whose surface has been processed by printing or the like with characters (9 figures), patterns (1 color), etc. as appropriate.

The plate material may be copper, aluminum, brass, etc.

The transparent synthetic resin having elasticity that encases this is acrylic, epoxy, polyurethane, polycarbonate thread, etc. containing a rubber component. The hard synthetic resin that covers the outer surface of the envelope is an acrylic resin that does not contain rubber components.

Such as epoxy resin.

The drawing shows an embodiment of the present invention on an outdoor nameplate.

When applied to plate-shaped products such as automobile display boards,
In FIG. 1 showing one example, (1) shows an aluminum processed plate on which an anodized film is formed on the surface, the film is colored if necessary, and the required characters are added. A transparent synthetic resin (2) having elasticity is coated on the entire circumferential surface of the processed plate (1), that is, its front and back surfaces and the same side surfaces, and is bonded to this as a single body.1 For example, a modified acrylic resin manufactured by Mitsubishi Rayon. A plate-shaped molded envelope (2) made of Acrylite 1R is provided in one body, and at least the surface of the envelope (2) is coated with a hard transparent synthetic resin (3), for example, a hard transparent acrylic resin. (3) shows a plate-shaped combined product for display that is coated and bonded. Since the back surface of this product is made of a modified acrylic resin layer having elasticity, it has the advantage that it can be airtightly bonded to the surface to which it is attached in a compressed and intimate state. Since its surface is a hard synthetic resin coating layer (3), it will not be damaged even if it hits objects.

To manufacture a combined product in which the processed aluminum plate (1) is wrapped and bound with an elastic transparent synthetic resin enveloping body (2),
Half of the resin is injected into a concave mold, and an aluminum processed plate (1) is placed on the filled layer with a gap between the outer periphery and the inner peripheral surface of the mold, and then the resin is poured on the upper surface. The remaining half is injected to form a filling layer, and the remaining half is solidified by a hardening agent, heating, ultraviolet irradiation, etc. while being connected as one body in the gap around the outer periphery of the filling layer metal plate 11.1 below L. can get. To cover the upper surface of the transparent envelope (2) with the hard transparent resin plate-shaped molded body 131, apply a resin liquid to an appropriate thickness on the upper surface of the envelope (2), and apply a hardening agent to the resin liquid. , solidify by heating or irradiation with ultraviolet rays, or injection mold on the surface by injection molding, so that the covering layer (3) thermally bonded to the surface of the envelope (2) is solidified and molded. .

If it is necessary to cover and protect the back side of the elastic transparent synthetic resin enveloping body (2), as shown in the second figure, the back side of the enveloping body (21) is also coated in the same manner as described above. A plate-shaped molded body coated with a hard synthetic resin (3
) can also be used as an integrated display product. In this case, if it is preferable that the aluminum processed plate (1) is embossed to display characters or the like so that the condition of the back surface cannot be seen through, the hard synthetic resin coated molded body (31 is an opaque hard material) on the back surface. It is formed from a resin or a transparent resin made opaque by adding a pigment to it.The covering molding layer (31) is prepared separately in advance, and a transparent or opaque adhesive is applied to the outer surface of the covering body (2). It is also possible to combine them into one body through a wafer to make a combined product for display.

In this case, before applying the adhesive, a transparent primer may be applied to the outer surface of the envelope (21) to further strengthen the bond.

The material of the envelope (2) and the cover (3) is preferably the same resin, and as in the illustrated embodiment, both are made of, for example, acrylic resin.

The embodiment shown in the second figure shows an integrated display product in which the plate-shaped envelope (2) is sandwiched and bonded with plate-shaped covers +31131 from both upper and lower surfaces. 2) If it is preferable to make an enclosed display integrated product that also covers the peripheral side, the upper coating layer (3) is attached to the peripheral edge with a downward surrounding protrusion, as shown in Figure 3, for example. (3a) is formed into a dish-shaped coating layer (3) to provide an integrated product for display. One example of its production is to make a layered structure in which the envelope (2) is bonded in advance to the top surface of the lower coating layer (3), leaving an overlap margin around the outer periphery, and then this is placed in the mold of an injection molding machine. In this state, a dish-shaped upper coating layer (3) is heat-sealed by injection molding to the upper surface of the envelope (2), the external use surface and the upper overlap area of the lower coating layer. Manufactured by forming.

FIG. 4 shows a perspective view of the product shown in FIG.

The combined products shown in each of the above examples can be used by being attached to the outside of a car, for example, and exposed to direct sunlight.

@ is wrapped in a transparent synthetic resin envelope (2) that has elasticity, so the envelope (2) covers the metal workpiece 11.
It absorbs the elongation of 1 and returns to its original state by following the shrinkage without causing cracks in the envelope (21 and the covering molded body (3) on its outer surface), and furthermore, the covering molded body ( 3) is
It is possible to prevent the envelope (2) from being damaged by contact with equipment from the outside world, thus maintaining good see-through display. Of course, the display of the metal work includes a design display with only a decorative surface of a design or pattern without text, and the metal work also includes three-dimensional crafts such as metal casting or sculpture. It is clear that it can be a good product. Further, the wall thickness of the envelope and the covering molded body can be selected as desired. It goes without saying that the product of the present invention can also be produced as an indoor device depending on the intended use.

As described above, according to the present invention, the metal workpiece is encapsulated with a transparent synthetic resin having elasticity, and at least a part of the outer surface of the encapsulating body is covered with a transparent hard synthetic resin molding. Even if the metal workpiece expands and contracts in response to large temperature changes in the outside world, the transparent synthetic resin encapsulation and the transparent hard coating molded product do not crack at all, maintaining surface hardness and wear resistance over a long period of time. As a good and stable see-through display product, it can be used indoors as well as outdoors.
