Problems to be solved by the invention

However, the carbon fired body is black, and it is sometimes desirable to color the periphery thereof with a different color.

For coloring, depending on the color, a paint containing a pigment may be applied and then fired at a high temperature. The inventors of the present invention have found that in this case, when a pigment-containing paint is applied only to a carbon fired body and fired at a high temperature, small defects are likely to occur in the colored layer formed in this manner, and the defects change the color of the portion and reduce the durability, and have conducted extensive studies to obtain the present invention.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an ornamental article having beads which hardly cause defects in a colored layer formed around a carbon fired body.

Means for solving the problems

In order to achieve the above object, an ornament according to an embodiment of the present invention is an annular ornament formed by stringing a plurality of beads, wherein at least one bead is formed around a carbon fired body having a crystal structure processed into a shape of the bead: a penetration layer having a portion penetrating into small voids of a peripheral surface of the carbon fired body; a colored layer which is provided on the outer side of the permeation layer and is formed by applying a paint containing a pigment and baking the paint; and a transparent coating layer provided on the outer side of the colored layer.

In the ornament according to the embodiment of the present invention, the pigment of the colored layer may be red, and the black color of the carbon-fired body may be superimposed on the red color of the colored layer, so that the bead may be deep red or bovine.

In the ornament according to the embodiment of the present invention, an adhesive layer may be provided between the permeation layer and the colored layer.

Effects of the invention

According to the present invention, there can be provided an ornamental article having beads in which defects are less likely to occur in a colored layer formed around a carbon fired body.

Detailed Description

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. Fig. 1 is a schematic plan view of an ornament 1 according to an embodiment of the present invention. The ornament 1 is an annular member formed by stringing a plurality of beads 2, …. As shown in fig. 2, the beads 2 are provided with through-holes 2a through which a string (not shown) is passed, and the ends of the string passed through the through-holes 2a, … of all the beads 2, … are tied to form a loop.

As shown in fig. 3, the beads 2 are formed with layers (a permeation layer 4, a colored layer 5, and a coating layer 6) described later around the carbon fired body 3 processed to have a crystal structure in the shape of the beads 2. The carbon fired body 3 has a crystal structure integrated at high density and is integrated as a whole. This carbon fired body 3 can be produced as follows. That is, pitch (coal tar pitch or the like) or the like is added as a binder to carbon powder of carbide such as graphite or bamboo carbon and is solidified, and is pressed and molded into a predetermined block (for example, a rectangular block) by pressing from all directions by water pressure or the like. Next, the block is fired at about 1200 ℃ in an oxygen-deficient state. At this time, since a plurality of small voids are generated inside the block, pitch (coal tar pitch or the like) is impregnated and re-fired. The impregnation and re-firing of the pitch is usually carried out several times. Thereafter, the block is fired at a higher temperature (e.g., about 2000 to 3000 ℃). Then, due to crystallization (graphitization), the block becomes a crystalline structure with integration at high densityAnd a member integrally formed. In addition, when the pressure is applied in all directions by the water pressure during the press molding, a member in which the direction of crystallization is not deviated can be formed. Thereafter, the heating was stopped, and the mixture was cooled, separated into a plurality of beads and processed into the shape of beads 2. Since the binder is volatilized in the carbon fired body 3, approximately 100% (99% or more) is a carbon material. In addition, the bulk density (bulk specific gravity) can be set to 1.77Mg/m³The above.

The carbon fired body 3 is a carbon material, and therefore, is very lightweight, and the carbon material is the same as a constituent material of an organic material forming a human body, and therefore, is highly safe to the human body. The beads 2 may accidentally collide with another object (another bead 2 or the like) by coming into contact with the object, dropping, or the like, and even in such a situation, the carbon fired body 3 is hard and has sufficient physical strength and is not easily broken. In addition, since the carbon fired body 3 is substantially 100% carbon material, it absorbs heat from the human body and the outside and radiates a large amount of far infrared rays, and it acts on the subcutaneous tissue, blood vessels, and the like of the person wearing the ornament 1 to improve blood flow, thereby contributing to health promotion.

A permeable layer 4 is provided on the outer side of the carbon fired body 3. The penetration layer 4 has a portion penetrating into small voids of the peripheral surface of the carbon fired body 3. The carbon fired body 3 generates small voids upon firing. The voids are reduced or diminished by the impregnation and re-firing of the pitch, but are difficult to eliminate completely. The degree of the void can be indicated by the bulk density. The carbon fired body 3 is immersed in a solution in which a resin such as cellulose is dissolved by a solvent. When there are small voids in the vicinity of the peripheral surface of the carbon fired body 3, moisture, air, or the like in the voids are replaced with the solution. Thereafter, the solvent of the solution is volatilized and solidified. The permeation layer 4 is a layer obtained by solidifying the solution, and is very thin (for example, about 0.5 μm or less) compared with the colored layer 5, the coating layer 6, and the like.

A coloured layer 5 is provided on the outside of the permeation layer 4. The colored layer 5 is formed by applying a paint containing a pigment and firing the paint at a high temperature. The pigment is a pigment of red or the like. The coating material is, for example, an acrylic resin coating material, and is applied to a predetermined thickness (for example, about 15 μm) by a spray coating method or the like. The firing is performed, for example, at about 180 ℃ for about 1 hour. According to the colored layer 5, an adhesive layer 7 may be provided between the colored layer 5 and the permeation layer 4 as shown in fig. 4 in order to improve adhesion. The adhesive layer 7 can be formed by applying a paint (for example, an acrylic resin) containing no pigment thinly (for example, about 1 μm) and baking the paint at a high temperature.

An application layer 6 is provided on the outer side of the colored layer 5. The coating layer 6 is transparent. The coating layer 6 can be formed by applying a paint containing no pigment and firing at a high temperature. The coating material is, for example, an acrylic resin coating material, and is applied to a predetermined thickness (for example, about 10 μm) by a spray coating method or the like. The firing is performed, for example, at about 180 ℃ for about 1 hour.

The beads 2 of this structure appear in the color of the pigment of the colored layer 5, but are superimposed with the black color of the carbon fired body 3. For example, when the pigment of the colored layer 5 is red, the black color of the carbon burnt body 3 is superimposed on the red color of the colored layer 5, and the bead 2 is dark red or bovine blood. The coating layer 6 protects the colored layer 5 so that no defect is present in the vicinity of the peripheral surface of the colored layer 5. The penetration layer 4 penetrates into and fills the small voids on the peripheral surface of the carbon fired body 3, so that even if there are small voids (indicated by reference sign G in fig. 5) on the peripheral surface of the carbon fired body 3 when the paint containing the pigment at least in the colored layer 5 is fired at a high temperature, there is no case where moisture, air, or the like expands and seeps out to form small defects in the vicinity of the inner surface of the colored layer 5. As a result, the beads 2 can be prevented from being deteriorated in durability due to a change in color of the portion caused by the defect. It is noted that fig. 6 shows the absence of the permeation layer 4 and the reference D indicates a defect.

The shape of the bead 2 is not limited, and may be, for example, a spherical shape, a circular plate shape, a chess-shape, or a spindle-shape. The size of beads 2 and the number of beads used in article 1 may be determined as desired or desired depending on the mode of use (bracelet, necklace, anklet, bead string, watchband, etc.). For example, the size of the bead 2 is 6mm, 10mm, or the like. Further, the ornament 1 may be formed of the beads 2, … having different sizes. Further, at least one of the plurality of beads forming the ornament 1 may be the bead 2, and the remaining beads may be configured as another configuration.

The ornament according to the embodiment of the present invention has been described above, but the present invention is not limited to the description of the embodiment, and various design changes can be made within the scope of the description of the technical means.
