Description

[Detailed description of the invention]

0001

[Field of Industrial Application] This invention relates to a synthetic resin architectural decorative material, and more particularly to a synthetic resin architectural decorative material formed on the surface of architectural members such as handrail cap covers. be.

0002

2. Description of the Related Art Generally, in handrails installed on stairs or walls, the surface of a metal base is covered with a decorative material such as a synthetic resin kasagi cover to enhance visual beauty.

[0003] Conventionally, this type of decorative material is generally known to be made by extrusion molding a soft (semi-hard) vinyl chloride resin to which a coloring pigment is added. In addition, the surface may be embossed, or a transparent layer may be integrally formed on the surface of the base material during molding to achieve a uniform surface finish, or metallic pigment may be added to eliminate a monotonous color tone. Additives are also used.

0004

[Problems to be Solved by the Invention] However, in conventional products to which colored pigments are added, the feel of the synthetic resin itself, the so-called plastic feel, is emphasized, and the properties of other constituent members and surrounding members, that is, metal materials, are emphasized. There was a sense of incongruity between the metallic feel and the natural feel of the wood, making it difficult to achieve harmony. Furthermore, when the surface is embossed or the surface layer is uniformly finished, the effect of removing the dice mark can be obtained, but the color tone cannot be changed. In addition, in the case of products with metallic pigments added, it is possible to give a metallic feel to the surface and eliminate the sense of incongruity with other metal parts to some extent, but in conventional metallic decorative materials, the particle size is generally not visible to the naked eye. Since the amount of fine-sized (specifically 50 μm or less) metallic pigment added is 1.5 to 2.0 parts by weight, the color of the metallic pigment appears excessively and erases the color tone of the base material. There was a problem.

As a means to solve these problems, a transparent layer is coated on the surface of a colored layer with an uneven pattern to create a wood grain pattern by varying shading, or a thin film sheet with a pattern is laminated on the surface to create a pattern. However, these methods require complicated and expensive molding, and do not sufficiently solve the problem of monotony.

[0006] This invention was made in view of the above circumstances, and can be easily molded, and based on the color tone of the inner layer,
The object of the present invention is to provide a synthetic resin architectural decorative material that exhibits a three-dimensional metallic appearance.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the synthetic resin architectural decorative material of the present invention includes an inner layer made of a colored opaque synthetic resin and an integrally formed surface of the inner layer. It consists of a transparent synthetic resin surface layer that is coated, and a metallic pigment is added to the surface layer in an oriented manner.

In this invention, the metallic pigment may be the metal foil itself as long as it is added to the surface layer with orientation, but it is preferable that the metal foil has corrosion resistance and a surface layer on the surface of the metal layer. It is better to use a flat chip coated with a transparent synthetic resin layer having an affinity for . In this case, the metal layer may be, for example, a metal foil such as aluminum foil, copper foil, nickel foil, gold foil, or silver foil, or may be a PET film with aluminum vapor-deposited. In this case, the shape of the flat chip may be rectangular, square, triangular, circular, etc., but it is necessary that all the shapes are at least the same.

[0009] The metallic pigment alone may have any size as long as it is visible to the naked eye, and the amount added may also be arbitrary, but preferably the size of the metallic pigment is 100 to 500 μm. In addition, it is preferable that the amount added in the surface layer is 0.1 to 0.5 parts by weight.

0010

[Function] According to the synthetic resin architectural decorative material of the present invention constructed as described above, the transparent synthetic resin surface layer is integrally coated on the surface of the colored opaque synthetic resin inner layer. By adding the metallic pigment with orientation, the metallic feel of the large particle size metallic pigment is synergized based on the color tone of the inner layer, resulting in a cosmetic material that gives a three-dimensional metallic color tone. obtained,
It can be used not only for handrails such as handrail covers and caps, but also as a decorative material for a wide range of architectural applications.

[0011] Furthermore, by forming the metallic pigment on the surface of the metal layer using a flat chip coated with a transparent synthetic resin that has corrosion resistance and affinity with the surface layer, it is possible to keep the reflection angle of light constant and add a small amount. The amount increases the reflection efficiency so that the color of the inner layer can be seen through without being inhibited by the metallic pigment. Furthermore, deterioration of the chip due to corrosion or deterioration of the surface layer made of transparent synthetic resin material can be prevented.

[0012] Also, the size of the single metallic pigment is 1
00 to 500 μm, and the amount added in the surface layer is 0.
．． By adding 1 to 0.5 parts by weight, the metallic pigment can be added efficiently, and the particle size of the metallic pigment can be made large enough to make its chips visible, so that the color tone of the metallic pigment and the color tone of the inner layer are three-dimensional. It is possible to express a mixed metallic feel.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows an exploded perspective view of the decorative material of the present invention used in a Kasagi cover.

[0015] The Kasagi cover 1, which is a decorative material of the present invention, has the following features:
It is composed of an internal layer 3 having an arcuate cross section that is covered on the upper surface of the metal base 2, and a surface layer 4 that is integrally coated on the surface of this internal layer 3.

The inner layer 3 is made of a colored opaque synthetic resin, such as soft or semi-hard vinyl chloride. In this case, a small amount of a coloring pigment (phthalocyanine green) based on titanium oxide can be used to give the inner layer 3 a green pastel color, for example.

As shown in FIGS. 2 to 4, the surface layer 4 is made of a transparent synthetic resin, such as vinyl chloride, to which a metallic pigment 5 is added with orientation.

In this case, the metallic pigment 5 is made of a rectangular flat metal foil 6 whose surface is coated with a transparent synthetic resin layer 7 having corrosion resistance and affinity with the surface layer 4, as shown in FIG. It is made of shaped chips. For example, the metal foil 6 has a thickness of about 12 μm, and the vertical and horizontal dimensions are 100 μm×14
0 μm aluminum foil is used to give it a white color. Further, the amount of the metallic pigment 5 added to the single surface layer 4 is 0.1 to 0.5 parts by weight.

Note that the metal foil 6 does not necessarily have to be aluminum foil, but may be copper foil (copper color), nickel foil (aluminum color), gold foil (gold color), or silver foil (silver color) depending on the desired color. ) can be used.

In addition, the synthetic resin layer 7 having corrosion resistance and affinity has corrosion resistance to prevent reflection deterioration due to oxidation on the surface of the metal foil 6, and also has corrosion resistance to prevent reflection deterioration due to oxidation of the surface of the metal foil 6. It is necessary to prevent precipitation on the surface side of the layer 4 to confine the metal foil 6 and to be compatible with the vinyl chloride of the surface layer 4. As this synthetic resin, an acrylic resin is generally used, but a plasticizer may also be used. However, the condition is that it be transparent. In addition, the synthetic resin layer 7 may be colorless or colored as long as it is transparent.
If it is colored, it is necessary to avoid colors that inhibit the reflection of metallic pigments, such as dark colors, and to select pigments that tend to cause reflection of metallic pigments.

The vertical and horizontal dimensions of the metallic pigment 5 are as described in 1 above.
It is not limited to 00 μm x 140 μm, but 10
It may be within the range of 0 μm to 500 μm. Further, as long as the metallic pigment 5 has a flat shape, its shape does not necessarily have to be rectangular, and may be any shape such as a square, a triangle, or a circle. However, all shapes must be the same. By making the metallic pigment 5 flat and giving it orientation, the flat surface becomes a transparent surface, making it possible to maintain a constant light reflection angle and improve reflection efficiency with a small amount added.

[0022] In the above explanation, a case has been described in which the metallic pigment 5 is coated with a transparent synthetic resin layer having corrosion resistance and affinity on the surface of the metal foil 6, but it is not necessarily necessary to have such a structure. For example, as shown in FIG. 6, a transparent synthetic resin layer 10 having corrosion resistance and affinity may be coated on the surface of an aluminum vapor-deposited layer 9 in which aluminum is vapor-deposited on a PET film 8.

Next, a process of manufacturing the Kasagi cover 1 by integrally molding the inner layer 3 and the surface layer 4 formed as described above will be explained.

First, the metallic pigment 5 is added to the vinyl chloride resin resin together with a plasticizer, a stabilizer, and a lubricant and mixed in a mixer to produce a powder compound. This powder compound is then plasticized and melted in a kneading extruder. A pellet compound having a diameter of about 2 to 3 mm is produced using the same method, and a pellet compound for the inner layer is produced in substantially the same process as the compound for forming the surface layer 4.

Next, when the pellet compounds of the surface layer 4 and the inner layer 3 are simultaneously molded using an extrusion molding machine, the surface layer 4 is integrally laminated on the surface of the inner layer 3 and the Kasagi cover 1 is formed. molded. At this time, when the metallic pigment 5 in the surface layer 4 is molded, it is mixed so that its flat surface is a transparent surface and has orientation in the length direction, and is arranged on the inner side of the surface layer 4. (See Figure 4). Here, since the metallic pigment 5 is arranged on the inner side of the surface layer 4, even if the surface is scratched, the scar can be made difficult to see.

[0026] Then, by placing the cap cover 1 on the metal base 2, the cap of the handrail can be formed (Figs. 7 and 8).
reference).

[0027] Note that the handrail supports 10 can also be covered with a decorative material in the same manner as the Kasagi cover 1, and the end caps 11 provided at the ends of the handrail can also be covered with decorative materials. . In this case, the end cap 11
is molded by injection molding.

In the surface layer 4 of the handrail Kasagi cover 1 and end cap 11 formed as described above, the light that passes through the transparent part of the surface layer 4 and enters the surface of the inner layer 3 is as shown in FIG. As shown by the solid line in FIG. It is reflected at a specular reflection angle θ that is symmetrical with respect to the angle θ. Therefore, the color of the inner layer 3 (green) is recognized by the light reflected from the inner layer 3, and these colors are mixed three-dimensionally due to the metallic color caused by the light reflected from the metallic pigment based on this color. This gives the viewer a sense of three-dimensional color tones.

[0029] In the above embodiment, the case where the decorative material of the present invention is used as a handrail cap cover is explained, but of course it can also be used in other parts other than the cap cover, such as ceiling parting materials, around stairs, skirting boards, sizing materials, and clothes lines. It can be used for multiple purposes such as rods and pipes for various purposes.

[0030]

[Effects of the Invention] As explained above, since the synthetic resin architectural decorative material of the present invention is constructed as described above,
The following effects can be obtained.

1) According to the synthetic resin architectural decorative material according to claim 1, the transparent synthetic resin surface layer integrally coats the surface of the colored opaque synthetic resin inner layer. Since the pigment is added with orientation, the metallic feel of the large particle size metallic pigment is synergized with the color of the inner layer as the base color, forming a cosmetic material with a three-dimensional metallic color tone. be able to.

2) According to the synthetic resin architectural decorative material according to claim 2, the flat chip has a metallic pigment coated on the surface of the metal layer with a transparent synthetic resin layer having corrosion resistance and affinity with the surface layer. In addition, since the flat chip has its flat surface as a transparent surface, the reflection efficiency can be increased by keeping the reflection of light constant and adding a small amount, so that the color of the internal layer is inhibited by the metallic pigment. It can be seen from the outside without being exposed. Furthermore, it is possible to prevent the decorative material from peeling off due to corrosion or deterioration.

3) According to the synthetic resin architectural decorative material according to claim 3, the size of the metallic pigment alone and the amount added in the surface layer are adjusted efficiently so that the color of the inner layer is not impaired; Furthermore, by making the particle size of the metallic pigment such that its chips are visible, the two colors can be mixed three-dimensionally, giving the viewer a metallic sensation.
