Next, embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

As shown in FIG. 1, the sheet-like body (hereinafter, abbreviated as sheet-like body) 1 containing the lacquer coating film of the first aspect of the present embodiment includes a lacquer coating film layer 2 made of a cured lacquer paint. The woven cloth 3 is composed of a hardened glue lacquer layer 4 made of glue lacquer that has been infiltrated and hardened in the woven cloth 3, and the woven cloth 3 is integrally adhered to the lacquer coating layer 2 via the hardened glue lacquer layer 4. ing.

Since the woven fabric 3 is integrally adhered to the lacquer coating film layer 2 via the cured glue lacquer layer 4, the sheet-like body 1 has, for example, a tensile stress in the range of ^{15 to 17 N / mm 2.} ..

The sheet-like body 1 has, for example, a lacquer coating film layer having a thickness of 50 μm or less and an overall thickness in the range of 0.4 to 2.0 mm, but depending on the application, it has a thickness of 2.0 mm or more, for example, 4. The thickness may exceed 0 mm, and a smooth surface is provided on the opposite side of the surface to which the woven fabric 3 is adhered. The surface of the lacquer coating layer 2 opposite to the surface to which the woven fabric 3 is adhered is a surface to which the surface state of the substrate 5 (see FIG. 2) used in the manufacturing method described later is transferred. For example, it may be a pear ground.

The sheet-like body 1 shown in FIG. 1 can be manufactured, for example, as follows.

First, as shown in FIG. 2, the lacquer coating film layer 2 is composed of a lacquer coating film 2a obtained by applying a lacquer coating film 2a to the surface of a substrate 5 from which the lacquer coating film layer 2 can be peeled off, drying and curing the lacquer coating film 2a, and then curing the substrate 5. To form.

As the substrate 5, a flat plate made of a synthetic resin excluding polyethylene terephthalate (PET) can be used. Examples of the synthetic resin constituting the substrate 5 include polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and the like, and among these, the releasability is the best. To PVC is preferable.

As the lacquer paint 2a, one containing refined lacquer obtained by refining raw lacquer can be used. The raw lacquer is obtained by filtering sap obtained from lacquer as a tree, and the refined lacquer is obtained by kneading and stirring the raw lacquer to disperse the emulsion, and then heating and dehydrating to remove a total amount of 3 to It is a transparent dark lacquer liquor made up to 5% by mass. In the step of obtaining the refined lacquer, the kneading and stirring may be referred to as "softening" and the heating and dehydration may be referred to as "kurome".

The quality of the raw lacquer and the refined lacquer is regulated by the Japanese Industrial Standards (JIS K-5950), and the lacquer paint 2a containing such refined lacquer is obtained from, for example, Tsutsumi Asakichi lacquer shop (Kyoto Prefecture). be able to.

The lacquer paint 2a is, for example, applied onto the substrate 5 so as to be 50 μm or less, and then held for a predetermined time (for example, 24 hours) in a constant temperature and humidity environment (for example, temperature 20 to 25 ° C., relative humidity 70%). The lacquer coating film layer 2 can be formed by drying and curing the lacquer coating layer 2. The lacquer paint 2a can be applied by a method such as brush coating, spraying, or roller coating.
Further, the lacquer paint 2a may be dried and cured by using a constant temperature and humidity dryer, but an instrument called "lacquer room (urushimuro or simply muro)" or "bath" traditionally used in lacquer crafts is used. You may use it.

By applying the lacquer coating film 2a so as to be 50 μm or less, the lacquer coating film layer 2 that has been reliably cured to the inside can be obtained by drying and curing in the constant temperature and humidity environment. If it can be surely cured to the inside, it may be applied so as to have a thickness of 100 μm or less, for example, in the range of 60 to 70 μm.

Although FIG. 2 shows a state in which a single lacquer coating film layer 2 is formed, a plurality of lacquer coating film layers 2 may be formed if necessary.

When the sheet-like body 1 shown in FIG. 1 is manufactured, the woven fabric 3 is then superposed on the lacquer coating film layer 2 formed on the substrate 5 as shown in FIG. As the woven cloth 3, a plain weave of natural fibers such as cotton and linen, for example, a lawn cloth can be used. When the woven fabric 3 made of the natural fiber is used, the obtained sheet-like body 1 is composed only of natural products, so that when the sheet-like body 1 is discarded, it is easily decomposed in the natural world, and the environment. The load can be reduced. As the woven fabric 3, a fabric made of synthetic fibers such as polyamide can be used, but in this case, when the obtained sheet-like body 1 is discarded, the environmental load becomes large.

When the sheet-like body 1 shown in FIG. 1 is manufactured, next, as shown in FIG. 4, glue lacquer 4a is applied over the woven cloth 3. The glue lacquer 4a can be applied to a thickness of 40 to 80 μm by a method such as brush coating, spraying, or roller coating. The glue lacquer 4a is made by kneading rice flour with the raw lacquer, and can be produced, for example, as follows.

When producing glue lacquer 4a, first, 5 parts by mass of rice flour is mixed with 22.5 parts by mass of water and stirred at room temperature (20 to 25 ° C.). When the water and rice flour are sufficiently mixed, the obtained mixture is heated at a temperature of 80 to 90 ° C. for 1 to 1.5 minutes with stirring to gelatinize the rice flour. If the rice flour is gelatinized, stop heating after 80 to 100 seconds (for example, 90 seconds), continue stirring while cooling, and when it returns to room temperature (20 to 25 ° C), mix 15 parts by mass of raw lacquer and glue. Obtain lacquer 4a.

When the glue lacquer 4a is applied over the woven cloth 3, the glue lacquer 4a infiltrates the woven cloth 3 and reaches the lacquer coating layer 2 on the substrate 5 side of the woven cloth 3, as shown in FIG. Therefore, the glue lacquer 4a is then dried and cured to form the cured glue lacquer layer 4. The dry curing of the glue lacquer 4a can be performed in the same manner as the dry curing of the lacquer paint 2a. As a result, the woven fabric 3 can be adhered to the lacquer coating film layer 2 via the cured glue lacquer layer 4.

In the present embodiment, in the steps shown in FIGS. 3 and 4, the woven cloth 3 is superposed on the lacquer coating film layer 2, and the glue lacquer 4a is applied from the woven cloth 3. However, the glue lacquer 4a may be applied on the lacquer coating layer 2, the woven cloth 3 may be layered on the glue lacquer 4a, and the glue lacquer 4a may be further applied on the woven cloth 3, as shown in FIG. As described above, the glue lacquer 4a can infiltrate the woven fabric 3 and reach the lacquer coating layer 2 on the substrate 5 side of the woven fabric 3.

In FIGS. 4 and 5, one woven cloth 3 is superposed on the lacquer coating layer 2, the glue lacquer 4a is applied on the woven cloth 3, and the lacquer layer 4 is dried and solidified to form the cured glue lacquer layer 4. As shown, a plurality of woven fabrics 3 may be laminated on the lacquer coating layer 2 as needed. In this embodiment, the thickness of the entire sheet-like body 1 obtained can be adjusted in the range of 0.4 to 2.0 mm by changing the number of layers of the lacquer coating film layer 2 and the number of woven fabrics 3. it can. Further, the thickness of the entire sheet-like body 1 obtained may be 2.0 mm or more, for example, 4.0 mm or more depending on the application.

If the woven fabric 3 is adhered to the lacquer coating layer 2 via the cured glue lacquer layer 4, then the woven fabric 3 adhered via the cured glue lacquer layer 4 as shown by an arrow in FIG. Each, the lacquer coating film layer 2 is peeled off from the substrate 5. Since the substrate 5 is made of a synthetic resin other than PET, the lacquer coating film layer 2 can be peeled off at the interface with the substrate 5, and the sheet-like body 1 shown in FIG. 1 can be obtained.

At this time, the surface opposite to the side where the woven fabric 3 of the lacquer coating film layer 2 is adhered via the cured glue lacquer layer 4 (the surface on the side where the lacquer coating layer 2 is adhered to the substrate 5) is the surface state of the substrate 5. Is in the transferred state. As a result, if the surface state of the substrate 5 is smooth, the surface opposite to the side where the woven fabric 3 of the lacquer coating film layer 2 is adhered via the cured glue lacquer layer 4 is a smooth surface. Form 1 can be obtained. Further, for example, if the surface state of the substrate 5 is satin-finished, the surface opposite to the side where the woven fabric 3 of the lacquer coating layer 2 is adhered via the hardened glue lacquer layer 4 becomes a satin-ground surface. The sheet-like body 1 is obtained.

Next, as shown in FIG. 7, the sheet-like body 6 including the lacquer coating film of the second aspect of the present embodiment is the surface opposite to the surface to which the woven fabric 3 of the lacquer coating film layer 2 is adhered. It comprises a material 7 exposed to and has a predetermined pattern or pattern displayed by the material 7. The sheet-like body 6 has exactly the same structure as the sheet-like body 1 of the first aspect shown in FIG. 1, except that the lacquer coating film layer 2 contains the material 7. Therefore, in FIGS. 7 to 9, the same components as those of the sheet-like body 1 are designated by the same reference numerals, and detailed description thereof will be omitted.

In the sheet-like body 6, the material 7 can be at least one material selected from the group consisting of the lacquer coating film layer 2 containing a pigment, metal powder, metal pieces, and shells. Here, when the surface of the coating layer 2 opposite to the surface to which the woven fabric 3 is adhered is a smooth surface and the material 7 is a metal powder or a metal piece, the sheet-like body 6 is exposed from the smooth surface. The surface of the metal powder or piece of metal can be provided with a lacquer-like pattern or pattern, and when the material 7 is a shell, the sheet-like body 6 is formed by the shell exposed from the smooth surface. The surface can be provided with a Raden-like pattern or pattern.

The sheet-like body 6 shown in FIG. 7 can be manufactured, for example, as follows.

First, as shown in FIG. 8, the material 7 exposed on the surface opposite to the surface to which the woven fabric 3 of the lacquer coating film layer 2 is adhered is arranged at a predetermined position on the surface of the substrate 5. When the material 7 is a metal powder such as gold powder or silver powder, a metal piece made of a metal foil such as gold leaf or silver foil, or a nacre layer portion on the inner surface of the shell, the material 7 is simply placed at a predetermined position on the surface of the substrate 5 and arranged. The placement can be completed.

When the material 7 is the lacquer coating film layer 2 containing the pigment, the lacquer coating film layer containing the pigment is drawn by the lacquer coating film 2a containing the pigment at a predetermined position on the surface of the substrate 5 and then dried and solidified. 2 can be formed. The drawing may be performed using a brush or the like, or may be performed using a silk screen. The dry curing of the lacquer coating material 2a containing a pigment can be carried out in the same manner as in the lacquer coating material 2a containing no pigment forming the lacquer coating film layer 2 in the production of the sheet-like body 1.

As the lacquer paint 2a containing a pigment, what is generally called colored lacquer can be used, and examples of the pigment include ferric oxide (valve handle) and titanium dioxide (titanium white). The colored lacquer used as the lacquer paint 2a containing the pigment can be obtained from, for example, Tsutsumi Asakichi lacquer shop (Kyoto Prefecture).

Further, instead of forming a predetermined pattern or pattern using the lacquer coating layer 2 containing a pigment, the lacquer coating 2a containing no pigment or the refined lacquer forming the lacquer coating layer 2 is coated with a vegetable dry oil. The shading pattern or the like may be formed by the lacquer paint 2a containing the oily lacquer to which the above is added.

After the material 7 is arranged on the surface of the substrate 5, then, as shown in FIG. 9, the lacquer paint 2a is applied to the surface of the substrate 5 on which the material 7 is arranged, dried and cured, and then placed on the substrate 5. The lacquer coating layer 2 composed of the cured lacquer coating 2a and containing the material 7 is formed. The application of the lacquer paint 2a and the subsequent drying and curing can be performed in the same manner as in the case of the sheet-like body 1.

After the lacquer coating layer 2 containing the material 7 is formed, the lacquer coating layer 2 is then formed in the same manner as the steps shown in FIGS. 3 to 6 when the sheet-like body 1 of the first aspect is produced. The woven cloth 3 is layered on top of the woven cloth 3, and the glue lacquer 4a is applied from above the woven cloth 3 and dried and solidified to form the hardened glue lacquer layer 4, so that the woven cloth 3 is coated with lacquer through the hardened glue lacquer layer 4. After adhering to the layer 2, the lacquer coating film layer 2 is peeled off from the substrate 5 together with the woven cloth 3 adhered via the cured glue lacquer layer 4. As a result, it is possible to obtain the sheet-like body 6 containing the material 7 exposed on the surface opposite to the surface to which the woven fabric 3 of the lacquer coating film layer 2 is adhered, as shown in FIG.

Conventionally, in the field of lacquer crafts such as lacquer painting and mother-of-pearl, a material 7 such as metal powder, metal foil, and shell is embedded in the lacquer coating film layer 2, and then the surface of the lacquer coating film layer 2 is polished with charcoal or the like. At the same time that the material 7 is exposed on the surface of the lacquer coating film layer 2, the surface of the lacquer coating film layer 2 is smoothly processed, and such processing requires skill.

However, according to the second aspect of the present embodiment, it can be obtained by forming the lacquer coating film layer 2 on the surface of the substrate 5 on which the material 7 is arranged and then peeling the lacquer coating film layer 2 from the substrate 5. The surface of the sheet-like body 6 becomes a smooth surface by transferring the surface state of the substrate 5, and the material 7 is exposed from the smooth surface. Therefore, the surface of the sheet-like body 6 has a lacquer-like or Raden-like pattern or pattern. The body 6 can be easily manufactured without requiring skill.

Next, examples of the present invention will be shown.
