Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a general-purpose makeup joint material and a manufacturing method thereof, and more particularly to a general-purpose makeup joint material capable of freely expressing a shape, color and pattern, and a manufacturing method thereof.

[0002]

2. Description of the Related Art Sealing materials are usually used for the purpose of watertightness or airtightness or holding or fixing of building members at joints formed in the gaps between adjacent building members such as inner wall materials, outer wall materials and floor materials. It is injected or fitted.

Generally, the sealing material is roughly classified into an irregular-shaped sealing material and a fixed-shaped sealing material. The irregular sealing material injected into the joint groove of the joint is mainly oil-based,
A polymeric material such as silicone is used, and there are various types of fixed sealing materials to be fitted into the joint groove, such as sealing the joint groove with a pressure contact piece.

However, in general, it cannot be said that these sealing materials are always considered to have a fine appearance and design. Therefore, a decorative joint material is used to cover the joint groove in which the sealing material is injected or fitted. Molded members made of resin or rubber may be used as the decorative joint material, but above all, there are attachment strips that cover the joint joint from the outside and the reverse for fixing the decorative joint material by pressing it into the joint groove. Many of them have a structure including a leg portion having a stopper.

FIG. 17 shows a state in which a conventional general makeup joint material is inserted into a joint groove. When the makeup joint material 100 is inserted into the joint groove 2 of the joint joint, the attachment strip 101 covers the joint groove 2. Further, the non-return piece 103 provided on the leg portion 102 is pressed against the building member 3 such as a wall material to fix the decorative joint material 100.

However, in such a decorative joint material, for example, when there is a step in the joint joint (that is, when there is a difference in height of the building member 3) as shown in FIG. 18, the attachment strip 10 is provided.
No. 1 cannot contact the building member 3b on one side (the right end portion 101a of the attachment strip in FIG. 18) and appears to be lifted from the surface.

[0007] Such a decorative joint material is usually manufactured by extrusion molding (for example, JP-A-11-336208).
(See Japanese Patent Publication), and the shape is uniform. Therefore, when the joint groove has a step or the width is not constant, it is not always possible to make up the joint properly.

Further, in such a makeup joint material, for example,
As shown in FIG. 19, it is virtually impossible to make the color pattern of the decorative joint material 100 the same as that of the wallpaper 104 around the joint. That is, the conventional makeup joint material manufactured by such extrusion molding has a drawback that it cannot meet the taste of consumers.

Further, such a decorative joint material cannot be applied because its legs cannot be inserted into a joint groove (so-called sleeping joint) formed by two building members closely approaching each other without a gap. Therefore, it is necessary to develop a general-purpose makeup joint material and a manufacturing method thereof that can appropriately meet the joint groove having various shapes as described above and the taste of the consumer.

To this end, a decorative joint material of the type that is applied from above the joints can be applied to joints having various different shapes, such as normal joints, sleeping joints, entering corner joints, and exiting joint joints. Become. Further, such a general-purpose decorative joint material of the type to be attached must be capable of freely expressing the shape, color and pattern as described above. Further, it is required to develop a manufacturing method capable of easily manufacturing such a general-purpose decorative joint material.

[0027]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the general-purpose makeup joint material of the present invention will be described below with reference to the drawings. still,
In this specification, positional relationships such as up, down, left, and right are all based on the positional relationships in the drawings used for the description.

The general-purpose decorative joint material of the present invention has a surface of a sheet-like base material made of paper or cloth formed in a certain shape.
It is a three-dimensionally formed transparent resin material. Then, as shown in FIG. 1, the general-purpose makeup joint material 1 is attached from above the joint groove 2 such as a joint joint to make the joint makeup. Therefore, the two building members 3 can be accurately attached even to so-called sleep joints where the two building members 3 are close to each other with almost no gap (see FIG. 2), and the makeup of the portion which has been difficult in the past can be easily applied. .

Another feature of the general-purpose decorative joint material of the present invention is that the transparent resin 4 is three-dimensionally formed on the sheet-shaped substrate 5 (see FIG. 1). By forming in this way, not only the surface of the sheet-shaped substrate 5 can be visually recognized through the transparent resin material 4, but also the light is refracted by the transparent resin material 4,
The color and the ground pattern on the surface of the sheet-shaped base material 5 appear to be colored on the surface of the resin material 4 which is transparent (refractive effect).

As described above, generally, it is not always easy to color a resin material with a fine color or pattern. However, in the present invention, due to the refraction effect, even if the transparent resin material is not directly colored, for example, by applying a wallpaper of the same material as the wallpaper around the joint to the sheet-shaped base material, a general-purpose makeup joint material Will have the same color pattern as the wallpaper.
Therefore, if you attach this general-purpose makeup joint material to the joint groove,
It is possible for the wallpaper to appear as if they were continuously connected (see Fig. 3).

On the other hand, by freely expressing the color pattern on the surface of the sheet-shaped substrate in advance, it is naturally possible to express the desired color, pattern, texture, etc. on the general-purpose makeup joint material. . For example, by depositing gold, silver, or the like on the surface of the sheet-shaped base material, the general-purpose decorative joint material of the present invention has a metallic tone, and a profound feeling can be obtained.

Further features of the general-purpose makeup joint material of the present invention are:
That is, the sheet-like base material is curved upward or bent into a V shape. In addition, the transparent resin material is formed such that it is thin in the central portion and thick in the peripheral portion.

Therefore, it can be accurately attached to joints having various shapes. Further, it can be accurately attached even to a joint groove having a step which cannot be properly applied with the above-mentioned conventional makeup joint material. FIG. 4 shows an example in which a general-purpose makeup joint material obtained by bending a sheet-shaped base material is attached to joints having steps.

Thus, for example, when the sheet-shaped base material is curved upward, when the building member 3a and the building member 3b have a step, the sheet-shaped base material can fill the step without difficulty. . Further, since the transparent resin material is formed in a thin state in the central portion as described above, the general-purpose makeup joint material as a whole is easily bent at the thin portion in the central portion, and the sticking work can be performed easily. Similarly, it is possible to easily attach and apply to a sleep joint having a step as shown in FIG.

As will be described later, the sheet-shaped substrate is V
When it is bent in a letter shape, it is possible to provide a decorative joint material that can be attached to a corner joint or the like by freely raising a transparent resin material. 6 and 7 show an application example of a general-purpose decorative joint material in which the sheet-shaped base material is bent in a V shape. Here, the general-purpose decorative joint material shown in FIG. 6 is a transparent resin material having a depressed central portion, and the general-purpose decorative joint material shown in FIG. 7 is a transparent resin material having a raised central portion. .

Further, to provide a decorative joint material which can be attached to the projected corner joint by bending the sheet-like base material in a V shape contrary to FIG. 6 and potting a transparent resin. Is possible. This will be described later, including the manufacturing method.

[Manufacturing Method of General-purpose Decorative Joint Material] Next, a manufacturing method of the general-purpose decorative joint material of the present invention will be described with reference to the drawings. At this time, it goes without saying that the present invention is not limited to the following embodiments.

[First Embodiment] A method for manufacturing a general-purpose makeup joint material to be attached to a linear joint groove will be described. First, although not shown, the sheet-shaped base material is cut into a tape shape having a predetermined length and width (cutting step). Here, as the sheet-like base material, any material having adhesiveness to the resin can be adopted, and specifically, papers, cloths, synthetic resin sheets, gypsum board, wallpaper, etc. are appropriately adopted.

Next, a transparent resin material is piled up on the surface of the tape-shaped sheet-shaped substrate. At that time, as shown in FIG. 8, if the transparent resin material 4 is simply raised to form a general-purpose makeup joint material (A), the peripheral edge portion of the general-purpose makeup joint material may be treated with resin after a certain amount of time. The material may be turned up due to hardening or deterioration of the material (B).

The reason why such a phenomenon occurs is that when the resin material is cured, the resin material generally shrinks, and an internal force for pulling the peripheral portion comes to work. Therefore, as shown in FIG. 1, if the transparent resin material 4 is piled up so that the central portion of the sheet-like base material 5 is thin and the peripheral portion thereof is thick, even if the resin material 4 is hardened, the above internal force is increased. It becomes weaker and preferable.

The material of the transparent resin material is not particularly limited as long as it has curability, and specifically, an ultraviolet curable resin, a thermosetting resin, a two-component resin, etc. are appropriately adopted. . Among them, the ultraviolet curable resin is more preferably used because it can be cured rapidly at an intended timing and the curing of the resin can be adjusted to some extent by adjusting the irradiation time of ultraviolet rays.

As the ultraviolet curable resin, a photosensitive resin,
Usual ones containing a photosensitive monomer, a photopolymerization initiator, a photosensitizer and the like may be used. Among them, urethane acrylic ultraviolet curable resin is preferably used because it is excellent in transparency, viscosity before curing, hardness after curing and the like, and further exhibits moderate surface tension in the potting step as described later. .

As described above, when the central portion of the sheet-like base material is curved upward, the general-purpose makeup joint material of the present invention can be accurately adhered to a joint joint having a step. did it. Further, it was more preferable to raise the transparent resin material such that the central portion of the sheet-shaped substrate was thin and the peripheral portion was thick. Therefore, a method of forming a general-purpose makeup joint material in such a shape will be described.

First, the tape-shaped sheet-shaped base material 5 is gently adhered to a mold 6 having a convex surface upward and temporarily fixed [forming step, see FIGS. 9 (A) and 9 (B)]. . This temporary fixing may be carried out as long as the adhered sheet-shaped substrate 5 does not separate from the mold 6 in the following steps, and if both are adhered with an adhesive or double-sided tape having such an adhesive strength. It is enough. When a so-called pressure-sensitive adhesive sheet having a release paper attached to the back surface of the sheet-shaped substrate 5 is used, it is more preferable that the release paper is attached without being peeled off and the die 6 is attached so that the subsequent attachment work can be easily performed. .

Next, the transparent resin material 4 is hung down, that is, potted, on the surface of the sheet-like base material 5 which is attached to the mold 6 and is in a curved state (potting step).
In this case, so-called potting machines may be used for potting, or manual potting may be performed.

Since the potted transparent resin material 4 is curved on the mold as shown in FIG. 10, the potted transparent resin material 4 naturally spreads on the surface of the sheet-like base material 5, and the sheet-like substrate is formed. The thickness of the central portion of the material 5 is thinner than that of the peripheral portion. At this time, when the ultraviolet curable resin, particularly the urethane acryl-based ultraviolet curable resin is used as the transparent resin material 4 as described above, the resin material 4 exhibits appropriate surface tension, and the resin material 4 has the edge of the sheet-shaped substrate 5. It is more preferable because it hardly leaks out.

According to the experiment, when the transparent resin material has a viscosity of 2000 to 2500 cps (20 ° C.), it was easy to spread naturally on the surface of the sheet-shaped substrate, and it was possible to work without leaking from the edge. Further, if the transparent resin material 4 does not spread out completely, it may be spread with a rod-shaped tool 7 having a sharp tip (shaping step, see FIG. 11).

Next, the potted or shaped transparent resin material 4 is cured (curing step). In this step, an ordinary curing method suitable for the material of the transparent resin material 4 may be used.

Specifically, for example, when an ultraviolet curable resin is used as the transparent resin material 4, although not shown, after potting or shaping is completed, the mold is placed on a conveyor and placed in the ultraviolet irradiation area. Pass through. that time,
According to the composition of the ultraviolet curable resin, the irradiation time can be adjusted within a range of several seconds to several tens of seconds, and ultraviolet rays can be irradiated to adjust the hardness.

[Second Embodiment] Next, a method for manufacturing a general-purpose makeup joint material to be attached to the entering corner joint will be described. In this embodiment, as in the first embodiment, after the sheet-shaped base material is cut into a tape shape having a predetermined length and width (cutting step), the tape-shaped sheet-shaped base material is V-shaped.
Bend into a letter shape (formation process). When it is difficult to bend the sheet-shaped substrate, it is more preferable to make a cut 8 in the longitudinal direction on the back surface of the sheet-shaped substrate 5 [see FIGS. 12 (A) and 12 (B)] because the sheet is easily bent.

Next, the tape-shaped sheet-shaped substrate 5 thus bent is temporarily fixed to a V-shaped mold 9 as shown in FIG. The temporary fixing method is the same as in the first embodiment.

Then, the transparent resin material 4 is potted on the V-shaped valley portion of the sheet-shaped substrate 5 (potting step), and the transparent resin material 4 is shaped as necessary (shaping step). At this time, as shown in FIG.
It is also possible to make the center part of the dent into a normal decorative joint material, or conversely, as shown in FIG. 15, it is possible to raise the center part of the transparent resin material 4 and shape it like a molding material. .

The general-purpose makeup joint material manufactured by the method shown in FIG. 14 corresponds to the general-purpose makeup joint material 1 in which the transparent resin material shown in FIG. 6 has a recessed center, and is also manufactured by the method shown in FIG. The general-purpose makeup joint material thus prepared corresponds to the general-purpose makeup joint material 1 shown in FIG. 7 in which the transparent resin material has a raised central portion.

[Third Embodiment] Next, a method for manufacturing a general-purpose makeup joint material to be attached to the projected corner joint will be described. In this embodiment, first, in the same step as in the first embodiment, a general-purpose makeup joint material having a shape as shown in FIG. 1 is once formed.

FIG. 16 is a perspective view showing a step of processing a general-purpose makeup joint material for a projected corner joint. The central part of the transparent resin material 4 of the general-purpose decorative joint material 1 is cut in the longitudinal direction [Fig.
(See (A)], and the sheet-shaped substrate 5 is bent at that portion (see FIG. 16B, the above cutting and bending step). Then, the transparent resin material 4a is potted to the bent portion [see FIG. 16 (C)], and the resin material is cured in the same manner as in the first embodiment (potting curing step).

If the transparent resin material 4a newly potted in this way is made of the same material as the transparent resin material 4 which has already been cured, it is integrated with the transparent resin material 4 by the potting curing step. Turn into. By the way, it is needless to say that in the cutting and bending step, the sheet-shaped substrate 5 is not cut, and in the potting curing step, the potted transparent resin material 4a is shaped appropriately.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various modifications can be made without departing from the essence thereof. . For example, as the transparent resin material, if the color or pattern of the surface of the sheet-shaped substrate is visible, a translucent material or a colored resin material may be used according to the taste of the consumer.

In addition, in order to improve the abrasion resistance, a transparent clear resin material as a general-purpose decorative joint material may be sprayed with a matte clear agent, and an anti-wear agent may be added to prevent deterioration of the resin material due to ultraviolet rays. Of course, it is possible to perform a treatment such as adding an ultraviolet absorber. On the other hand, the embodiment shows only the case where the sheet-shaped substrate is cut into a tape shape,
For example, it is naturally possible to form it into a circular shape, a square shape, or a patch shape and attach it to a hole in a wall or the like, or use it for one-point interior decoration or the like.

According to the present invention, it is possible to manufacture a general-purpose makeup joint material which can freely express the shape, color and pattern. Further, it becomes possible to manufacture a general-purpose makeup joint material that can also be applied to sleep joints, entrance corner joints, exit corner joints, and the like. Further, such a general-purpose decorative joint material can be easily manufactured by the present invention.
