DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin architectural decorative material, and more particularly to a synthetic resin architectural decorative material formed on the surface of a building member such as a handrail cover. is there.

[0002]

2. Description of the Related Art In general, in a handrail installed on a staircase or a wall, a cosmetic material such as a synthetic resin cover is covered on a surface of a metal base to enhance the visual appearance.

Heretofore, as this kind of cosmetic material, generally, a soft (semi-hard) vinyl chloride resin to which a coloring pigment is added is formed by extrusion molding. Also, at that time, the surface is embossed, or a transparent layer is integrally formed on the surface of the base material at the time of molding to finish the surface uniformly, or a metallic pigment is used to eliminate monotonous color tone Additions are also used.

[0004]

However, in the case where the conventional coloring pigment is added, the sense of the synthetic resin itself, that is, the so-called plastic sense, is emphasized, and other constituent members and surrounding members, that is, the metallic material are not included. A sense of incongruity between the metallic sensation and the natural sensation of the woody nature of the wood occurred, making it difficult to harmonize. In the case where the surface is embossed or the surface layer is uniformly finished, the effect of removing dice marks can be obtained, but the color tone cannot be changed. In addition, in the case of adding a metallic pigment, it is possible to give a metallic feeling to the surface and to alleviate the sense of incongruity with other metal members to some extent, but in a conventional metallic-like decorative material, the particle size is generally not visible. Fine size (specifically 50 μm
Since the addition amount of the metallic pigment of the following (1) is 1.5 to 2.0 parts by weight, there is a problem that the color of the metallic pigment appears excessively and the color tone of the base material is erased.

[0005] As means for solving these problems, a transparent layer is coated on the surface of a colored layer having an uneven pattern on the surface to produce a grain pattern by shading, or a pattern is formed by laminating a thin film sheet having a pattern on the surface. Although it is conceivable to use such a method, these methods require complicated and expensive molding and do not sufficiently solve monotonicity.

The present invention has been made in view of the above circumstances, and provides a synthetic resin architectural decorative material which can be easily molded and has a three-dimensional and soft metallic feeling based on the color tone of an inner layer. The purpose is to do so.

[0007]

In order to achieve the above object, a synthetic resin architectural decorative material according to the present invention comprises a colored opaque synthetic resin inner layer and an inner layer integrally formed on the surface of the inner layer. It is composed of a surface layer made of a transparent synthetic resin to be coated, and a metallic pigment and a pearl pigment are added to the surface layer with their respective orientations.

In the present invention, the metallic pigment may be the metal foil itself as long as it is added to the surface layer with an orientation, but preferably the metal layer has a corrosion resistance and a surface layer. A flat chip coated with a transparent synthetic resin layer having the following affinity is better. In this case, the metal layer may be a metal foil such as an aluminum foil, a copper foil, a nickel foil, a gold foil or a silver foil, or may be a pet film obtained by evaporating aluminum on a pet film. In this case, the shape of the flat tip may be any of a rectangle, a square, a triangle, a circle, and the like, but it is necessary that at least all of the flat tip have the same shape.

The above-mentioned pearl pigments are different from ordinary color pigments in optical properties, and are pigments that give pearl luster by regular multiple reflection, and can be formed, for example, by coating mica surface with titanium oxide. The metallic pigment may be of any size as long as it is visible, and may be added in any amount. Preferably, the size of the metallic pigment alone is 100 to 500 μm, and It is preferable to add 0.1 to 0.5 parts by weight in the layer. Further, the pearl pigment alone may be different in shape and size, but preferably in the form of a fixed scale, the size of which is about 1/10 of the metallic pigment, that is, 10 to 50 μm.
m is preferably 10 to 20 μm, and the addition amount in the surface layer is preferably 0.01 to 0.03 parts by weight.

[0010]

According to the synthetic resin architectural decorative material of the present invention configured as described above, a transparent synthetic resin surface layer integrally coated on the surface of a colored opaque synthetic resin inner layer. By adding the metallic pigment and pearl pigment with their respective orientations inside, based on the color tone of the inner layer, the metallic feeling of the metallic pigment with a large particle diameter and the pearl luster of the pearl pigment with a small particle diameter are synergized. As a result, a cosmetic material that allows the user to visually observe a three-dimensional and soft metallic color tone can be obtained, and can be used not only for handrails such as handrail covers and caps but also for a wide range of architectural decorative materials.

Further, a metallic pigment alone is formed by a flat chip in which the surface of a metal layer is coated with a transparent synthetic resin having corrosion resistance and affinity for the surface layer, and a pearl pigment is coated with titanium oxide on the surface of mica. By forming with a coated micro-flat chip and making each flat surface a see-through surface,
Since the reflection efficiency is enhanced by a small amount of addition while keeping the light reflection angle constant, the color of the inner layer can be seen through without being hindered by these pigments. Further, the deterioration of the chip due to the corrosion and deterioration of the surface layer made of the transparent synthetic resin material can be prevented.

The size of the metallic pigment alone is set to 1
The amount of the pearl pigment is about 1/10 of that of the metallic pigment, and the amount of the pearl pigment is about 1/10 of the metallic pigment. By 0.01 to 0.03 parts by weight, to efficiently add a metallic pigment and a pearl pigment,
In addition, the particle size of the metallic pigment is set to be large enough to allow the chip to be visually recognized, and the particle size of the pearl pigment is reduced, so that the color tone of each pigment and the color tone of the inner layer are mixed three-dimensionally, and are soft to the viewer. A metallic feeling can be expressed.

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

FIG. 1 is an exploded perspective view when the decorative material of the present invention is used for a coping cover.

The skirting cover 1, which is a decorative material of the present invention, comprises:
It is composed of an inner layer 3 having an arc-shaped cross section covered on the upper surface of the metal base 2, and a surface layer 4 integrally coated on the surface of the inner layer 3.

The inner layer 3 is formed of a colored opaque synthetic resin, for example, 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 exhibit, for example, a green pastel color as the inner layer 3.

As shown in FIGS. 2 to 4, the surface layer 4 is made of a transparent synthetic resin in which a metallic pigment 5 is added with an orientation and a pearl pigment 5a is added in a gap between the metallic pigments 5 with an orientation. For example, it is formed of vinyl chloride or the like.

In this case, as shown in FIG. 5, the metallic pigment 5 has a rectangular flat shape in which the surface of a metal foil 6 is coated with a transparent synthetic resin layer 7 having corrosion resistance and affinity for the surface layer 4. It is formed of a chip. The metal foil 6 has, for example, a thickness of about 12 μm and a vertical and horizontal dimension of 100 μm × 14.
An aluminum foil of 0 μm is used to give a white color.

The metal foil 6 does not necessarily need to be an aluminum foil, but may be a copper foil (copper color), a nickel foil (aluminum color), a gold foil (gold color) or a silver foil (silver color) depending on the desired color. ) Can be used.

Further, the synthetic resin layer 7 having corrosion resistance and affinity has corrosion resistance for preventing reflection deterioration due to oxidation of the surface of the metal foil 6, and the metal foil 6 has a surface formed by plating out. It is necessary to prevent the metal foil 6 from being deposited on the surface side of the layer 4 and confine the metal foil 6, and to have an affinity (compatibility) with the vinyl chloride of the surface layer 4. As this synthetic resin, an acrylic resin is generally used, but a plasticizer may be used. However, it is a condition that it is transparent. The synthetic resin layer 7 may be colorless or colored as long as it is transparent.
In the case of a color, it is necessary to avoid a color that hinders the reflection of the metallic pigment, for example, a dark color, and to select a pigment that easily reflects the metallic pigment.

The length and width of the metallic pigment 5 alone is not limited to the above-mentioned 100 μm × 140 μm, but may be in the range of 100 μm to 500 μm. If the metallic pigment 5 is flat, the shape is not necessarily required to be rectangular, and may be any shape such as a square, a triangle, or a circle. However, all the shapes need to be the same. By making the metallic pigment 5 flat and having orientation, the flat surface becomes a transparent surface, so that the reflection angle of light can be kept constant and the reflection efficiency can be increased with a small amount of addition.

In the above description, the case where the metallic pigment 5 is coated on the surface of the metal foil 6 with the transparent synthetic resin layer having corrosion resistance and affinity has been described. However, such a structure is not necessarily required. For example, as shown in FIG. 6, a pet film 8 may be formed by coating a surface of an aluminum vapor-deposited layer 9 obtained by vapor-depositing aluminum with a transparent synthetic resin layer 10 having corrosion resistance and affinity.

On the other hand, as shown in FIG. 7, the pearl pigment 5a is formed by coating the surface of a scale-like mica 5b with titanium oxide 5c. Although the shape and size of the pearl pigment 5a may be slightly different from each other, it is preferable that the pearl pigment 5a has a fixed shape, and the size is about 1/10 of that of the metallic pigment 5.
That is, the thickness is preferably 10 to 50 μm, more preferably 10 to 20 μm.

When light is incident on the pearl pigment 5a thus formed, the first light is reflected by the flat surface of the pearl pigment 5a, and the second light passes through the titanium oxide 5c and becomes mica. The third light is reflected on the bottom surface of the pearl pigment 5a. Therefore, this 3
Pearlescence can be imparted by regular multiple reflections by the seed light.

The metallic pigment 5 formed as described above
The mixing ratio of the pearl pigment 5a and the pearl pigment 5a is as follows.

That is, the addition amount of the metallic pigment 5 in the surface layer 4 is set to 0.1 to 0.5 parts by weight, and the pearl pigment 5a
In the surface layer 4 is 0.01 to 0.03 parts by weight.

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

First, a metallic pigment 5 and a pearl pigment 5a are added to a vinyl chloride resin resin together with a plasticizer, a stabilizer and a lubricant.
Is added and mixed by a mixer to produce a powder compound. The powder compound is plasticized and melted by a kneading extruder to produce a pellet compound having a diameter of about 2 to 3 mm and the surface layer 4 is formed. A pellet compound for the inner layer is manufactured in substantially the same process as the compound.

Next, when the pellet compound of the surface layer 4 and the inner layer 3 is simultaneously molded by an extruder, the surface layer 4 is integrally laminated on the surface of the inner layer 3 to form the coping 1. Molded. At this time, when the metallic pigment 5 in the surface layer 4 is molded, the flat surface thereof is used as a transparent surface and mixed so as to have an orientation in the length direction. Is mixed in the gaps between the metallic pigments 5 arranged in the same manner. In addition,
The metallic pigment 5 and the pearl pigment 5a are arranged on the inner side of the surface layer 4 (see FIG. 4). Here, since the metallic pigment 5 and the pearl pigment 5a are arranged on the inner side of the surface layer 4, even if the surface is scratched, scars can be hardly recognized.

Then, if the cap cover 1 is covered with the metal base 2, a cap portion of the handrail can be formed (FIGS. 8 and 9).
reference).

It is to be noted that the handrail support 10 can be covered with a cosmetic material in the same manner as the coping cover 1, and that the end cap 11 provided at the end of the handrail can also be used with a cosmetic material. . In this case, the end cap 11
Is formed by injection molding.

In the handrail cover 1 and the surface layer 4 of the end cap 11 formed as described above, the light passing through the transparent portion of the surface layer 4 and entering the surface of the internal layer 3 is shown in FIG. As shown by a solid line, light reflected at a specular reflection angle θ symmetrical to the incident angle θ, and incident on the metallic pigment 5 through the surface layer 4 is incident on the metallic pigment 5 as shown by a dashed line in FIG. The light is reflected at a regular reflection angle θ symmetrical with respect to the angle θ. Also,
Light transmitted through the surface layer 4 and incident on the pearl pigment 5a is subjected to regular multiple reflection (shown by a broken line in FIG. 4) as described above. Therefore, the color (green) of the inner layer 3 is recognized by the light reflected from the inner layer 3, and based on this color,
Due to the metallic color due to the light reflected from the metallic pigment and the pearl luster from the pearl pigment, these three colors are mixed three-dimensionally, giving the handrail viewer a silky soft tone.

In the above embodiment, the case where the decorative material of the present invention is used for a handrail cover is described. However, of course, other than the cover, a parting material for a ceiling, around a staircase, a skirting board, a sizing material, a clothesline. It can be used for various purposes such as rods and pipes for various uses.
