Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a method for manufacturing a ring capable of irradiating far infrared rays.
[0002]
[Prior art]
Conventionally, materials such as silica, alumina, and ceramics are known as materials that irradiate far infrared rays. Among these substances, it is known that 6-14 far infrared rays are emitted from silica, and these are effective in the treatment of severe cancer pain, polyps, hepatitis, ulcer pain, etc. in the medical field. It is also effective for the treatment of low back pain, stiff shoulders, rheumatism, arthritis, neuralgia, atopic dermatitis, etc. In the manufacturing industry, it is used for mats, sleep pillows, shoes, etc. It is known that there are concrete neutralization agents for redevelopment, construction, neutralizing agent for construction, deodorization and freshness maintenance for refrigerators at home, river purification, sewage / drainage treatment, and bactericidal sterilization effects for environmental facilities. In addition, it is known that there is a great growth and breeding effect in agriculture and livestock production by using activated water by irradiation with far infrared rays.
[0003]
[Problems to be solved by the invention]
Therefore, the present invention utilizes the epoch-making far-infrared irradiation effect as described above for the ring, and brings close to the physical effect based on the material in accordance with the mental effect of the precious metal jewelry, thereby promoting health and beauty. It is something to try.
[0004]
[Means for Solving the Problems]
Thus, one of the features of the manufacturing method of the present invention ring is that one or more recesses are formed on the inner diameter surface of the ring main body made of 18 gold, platinum, silver or other noble metal material.
[0005]
Another feature is a weight ratio of a raw silica powder having a particle size of 0.1 to 50 μm and a thermosetting resin selected from an epoxy resin, a phenol resin, a melamine resin, a urea resin, and a urethane resin. In addition, the particle diameter is preferably 3.5 μm, and the thermosetting resin is preferably a one-part epoxy compounded resin.
[0006]
Another characteristic is that the resin was softened by applying heat of about 50 ° C. to the mixture. Then, the mixture is poured into the recess of the ring body while being agitated and agitated to remove bubbles.
[0007]
Another feature is that it was placed in a sintering mold such as an electric furnace at 120 ° C. to 200 ° C. and then baked and hardened for 20 to 30 minutes. In addition, the temperature of the sintering type such as the electric furnace is preferably set to 170 ° C.
[0008]
【Example】
Next, when explaining the silica ring 1 shown in FIG. 1 and FIG. 2 as an example of a method for manufacturing a ring capable of performing far-infrared irradiation according to the present invention, the production of the ring body 1a will be described. Prior to the production of the ring body 1a. The design of the ring body 1a is made as a jewelry.
[0009]
The original design is made on the shape of the surface, the type, size, and arrangement of the decorative jewels, and the recesses formed on the inner diameter surface. Next, an original ring design (not shown) is produced by handmade the original design (not shown) with silver material. A rubber mold is created using silicon rubber based on this silver material handmade prototype.
[0010]
A required number of lost wax molds are created by the rubber mold, and the several wax molds are integrally connected to the lost wax core to form a tree (not shown). Pour plaster around this tree and harden it. Then put it in a kettle and bake it, and melt the wax of the tree inside to make a plaster mold. The base metal, that is, the 18 gold of the example is melted and poured into this plaster mold, and cast.
[0011]
Thereafter, the gypsum is removed, the tree is taken out, the ring body is cut off and temporarily polished, and the surface appearance and the inner diameter surface 1a1 as shown in FIGS. The ring main body 1a formed to have an appropriate width and depth at intervals is manufactured by a manufacturing method called a so-called lost wax method.
[0012]
Next, a raw silica powder having a particle size of about 3.5 μm and a one-part epoxy compound resin as an example of a thermosetting resin are mixed at a weight ratio of 1: 2, and this mixture is heated (about 50 ° C.). Is added to soften the resin, and the mixture is sequentially poured into the recesses 2a, 2b, and 2c of the inner diameter surface 1a1 of the ring body 1a, and at the time of pouring, the mixture is vibrated and stirred to remove bubbles.
[0013]
Then put in an electric furnace, heat at 170 ° C and bake and harden for 20 to 30 minutes. After natural cooling, polish with a reuter, polish with a puff and other finishing, and sinter silica on the inner surface 1a1 of the silica ring 1 The bodies 3a, 3b, 3c are deployed and completed. The particle diameter of the silica raw stone powder can be selected from 0.1 to 50 μm.
[0014]
Moreover, as an example of a thermosetting resin, a phenol-type resin etc. can be used other than the said epoxy resin. In addition, the weight ratio of the powdered silica raw material and the thermosetting resin can be selected from 1: 2 to 1: 5. Further, the portion into which the mixture is poured or injected is not limited to the recesses 2a, 2b and 2c of the ring body 1a, but may be a notch that is not shown but similar to the recess. And it is desirable for a silica sintered compact to be a contact surface of a wearer.
[0015]
In the above-described embodiment, the silica ring 1 is described as an example of the accessory, but the material of the ring main body 1a is not limited to 18 gold, but may be platinum, silver, or the like. Moreover, it can perform also about a shape, a surface pattern, surface jewelry decoration, and noble metal decoration, and is not limited to the external appearance of the said Example.
[0016]
【The invention's effect】
As described above, the ring obtained by the method of manufacturing the jewelry according to the present invention is made of the silica rough particle fine particle powder because the portion in contact with or corresponding to the wearer's skin is the silica rough particle fine particle powder, the resin, and the sintered body. By irradiating far-infrared rays, it is possible to promote the health and beauty by providing the infrared irradiation effect and the physical and mental effects of precious metal decoration.
