The present invention relates to a ceramic product for functional jewelry, and relates to a functional jewelry product that promotes blood circulation and metabolism as well as a luxurious appearance by combining an existing jewelry product with a ceramic product emitting far infrared rays and anions.

Ceramics have a much higher corrosion resistance, heat resistance, and abrasion resistance than metal materials and organic materials, and are known to have various functions such as optical functions, biological functions, electromagnetic functions, and mechanical functions. Recently, when heat is applied to ceramics, far infrared rays, which are a kind of electromagnetic waves, are known to be emitted, and various products using ceramics are being developed. In other words, a functional ceramic containing Pars (Korean Patent Application No. 2002-0015538) that emits far infrared rays, a method of manufacturing far-infrared radiation ceramics (Korean Patent Application No. 1997-008752), and a method of fixing ceramics or germanium to jewelry (Korea) Patent Application No. 1998-0035451) has been produced in a variety of fields, such as. However, the above products have the disadvantage of emitting far infrared rays but not negative ions.

Manufacturing method of functional ceramic powder using tourmaline and precious metal catalyst (Korean Patent Application No. 2002-0035799), Manufacturing method of composite functional sintered body using tourmaline and rare earth mineral (Korean Patent Application No. 2004-0049395), Tourmaline crushed in ceramic Accessories coated with powder (Korean Patent Application No. 2001-0073521), etc., introduce products that simultaneously emit far infrared rays and anions.

In the case of an anion generating mat (Korean Patent Application No. 2003-0001647), a product formed by mixing an appropriate amount of a mineral and a low elastic urethane resin to generate an anion is introduced.

As introduced above, most products have a problem in that their functionality is deteriorated when the coating layer is peeled off by adopting a method of coating a functional powder by mixing with various resins. In addition, when making a ceramic product using a functional powder, its use is so wide that it lacks the expertise for a particular product, revealing its limitations. In addition, due to the qualitative differences in the raw materials used in the manufacture of ceramic products, the same company's products are different in terms of their functionalities, resulting in poor reliability and being ignored by consumers when the market for health functional products is formed. It is acting as a great difficulty.

In addition, the existing functional products are mainly designed for the elderly and marketing is also carried out in the form of door-to-door sales for the elderly, there is a disadvantage that the consumption market is not largely formed. Currently, there are jewelry products that have been processed tourmaline ore, which is a type of tourmaline, and attached to rings, bracelets, necklaces, etc., but this product is being released as a jewelry product with tourmaline itself as a rare stone rather than functionality. However, when the product is worn as in the present invention, it is difficult to find a product that satisfies the functional aspects of promoting blood circulation and metabolism and the sophistication of jewelry products that can be worn casually even by young age groups.

The technical problem to be achieved by the present invention is to manufacture a ceramic product that is reliable in terms of functionality through the standardization of the manufacturing method of the ceramic product to which the conventional functional powder is added. According to the input amount of the functional raw material developed by the present invention can be characterized in that the amount of generation of far infrared rays and anions can be adjusted, and the quality improvement of the product is also expected by standardizing the composition ratio of the functional raw material. In the present invention, the sintered ceramic stone has a smooth surface state in the case of sintered ceramic stone by securing a powder having an average particle diameter of 3 to 7 μm in the crushing process of the raw material used for the ceramic stone, and thus has a good fit. In the sintering process, the standardized working conditions are provided to obtain a ceramic stone having a smooth color without glazing. The present invention is characterized in that it provides a ceramic stone having a smooth and soft brown surface even without adding a natural coloring agent. In addition, these ceramic products can be molded into a variety of designs desired by the consumer to enhance the sophistication of the jewelry as well as the effect of promoting health by combining with the jewelry products.

In the case of conventional functional products, even if the company product of the same far-infrared emissivity and anion generation amount, the difference in quality is so large that consumers are receiving functional products. Therefore, in order to solve these problems, the purpose is to make a ceramic stone for high-performance jewelry that emits more than 90% of far-infrared emissivity and more than 1,000 / cc anion through standardizing the mixing ratio of the functional raw material and the sintering process.

The configuration of the present invention can be broadly divided into a manufacturing process for producing a ceramic stone for high-performance jewelery that emits far infrared rays and negative ions at the same time, and a bonding process of the ceramic stone and jewelry products.

Figure 1 shows a manufacturing process of the ceramic stone. Details of each process are as follows.

[Stock]

In the present invention, the raw material refers to a functional powder, elvan, clay, alumina, and the like, and is dressed in the form of a powder. Functional powder is a raw material developed by the inventors, characterized in that obtained from natural ores. Powders of two or more minerals are obtained through appropriate blending criteria. The composition of the functional powder is shown in Table 1.

ingredient Content (wt%) SiO2 27.13 ZrO2 26.73 P2O5 10.93 Al2O3 7.34 FeO 1.60 Ce2O3 10.60 La2O3 5.14 Y2O3 1.07 ThO2 2.42 Gd2O3 1.27 Nd2O3 2.08 Sm2O3 2.04 Pr2O3 1.65 Total 100.00

[Stock input]

The received raw materials are added according to the proper blending ratio. The blending ratio of the raw material is characterized by consisting of functional powder (30 ~ 50wt%), elvan (20 ~ 40wt%), clay (20 ~ 25wt%), alumina (5 ~ 10wt%). There is a feature that can adjust the far-infrared emissivity and anion radiation amount according to the input ratio of raw materials. In addition to the raw materials, natural colorants, organic binders and the like are added in the secondary raw material mixing process.

[Primary raw material mixing and grinding]

The input raw material is subjected to the mixing and grinding process. In general, the mixing and crushing process of the raw material is carried out simultaneously through a ball mill. An appropriate amount of water is added to smoothly mix and grind the raw materials. It is characterized by having a working time of 24 to 48 hours in order to obtain a powder having an average particle diameter of 3 to 7 µm. If the average particle size is more than 7㎛, the surface of the ceramic stone has a rough feeling.

Raw material drying and packaging

After finishing the mixing and grinding of the raw materials is carried out to remove the moisture. The drying method is generally carried out by an instant drying method, characterized in that the dried powder blocks moisture absorption by avoiding contact with the atmosphere through vacuum packaging. In general, the moisture content should be managed below 3wt%, and if it exceeds 3wt%, it may cause deformation of the molding and increase the defective rate. The average particle diameter of the dried raw material is characterized in that 3 to 7㎛.

[Secondary raw material mixture]

The powder secured through the drying and packaging process is characterized by having a secondary raw material mixing process before compression molding. In the secondary raw material mixing process, a natural coloring agent that determines the color of the ceramic stone is added to the dried raw material. In general, a ceramic stone having a smooth brown surface can be obtained without adding a coloring agent. In addition, since the moisture content of the powder is less than 3%, the secondary raw material mixing process is carried out by adding 5 ~ 10wt% of the organic binder in order to obtain the original design during compression molding.

The secondary raw material mixing process is 14 to 20 hours and characterized in that the mixing process has a aging process for 20 to 26 hours.

[Compression molding]

After the prepared powder raw material is put into a mold, a molded product of a desired design is obtained through a compression molding process. The process is carried out by mounting a desired design mold on a conventional molding equipment. It is most important to keep the dosage of the mixed powder constant during the compression molding.

[Sintering]

Molded products made through compression molding are characterized in that the ceramic stone is finished through a high temperature sintering process. Sintering equipment can be sintered using a conventional electric furnace. It is important to use an electric furnace with a small internal temperature deviation because the internal temperature deviation of the electric furnace will lead to product defects. In other words, if the temperature difference between the wall side of the heating wire and the center of the electric furnace is not overcome, the defective rate increases and the productivity of the product decreases.

 Sintering process is characterized in that the progress through the detailed process as shown in Table 2.

order Temperature time One Room temperature ~ 200 ℃ 1 hour temperature rise 2 200 ℃ ~ 200 ℃ 1 hour hold 3 200 ℃ ~ 400 ℃ 1 hour temperature rise 4 400 ℃ ~ 400 ℃ 1 hour hold 5 400 ℃ ~ 600 ℃ 1 hour temperature rise 6 600 ℃ ~ 600 ℃ 1 hour hold 7 600 ℃ ~ 800 ℃ 1 hour temperature rise 8 800 ℃ ~ 800 ℃ 1 hour hold 9 800 ℃ ~ (1100 ~ 1150) ℃ (2-3 hours) temperature rise 10 (1100 ~ 1150) ℃ ~ (1100 ~ 1150) ℃ (4-6) time keeping

Through the above high temperature sintering process, the molding made through compression molding is made of high functional ceramic stone. The sintered ceramic stone is selected through quality inspection and then has the value as a product through bonding with jewelry products.

Bonding process with a jewelry product consists of a bonding process using a conventional epoxy resin. Jewelry products are processed through the usual 14K, 18K, 24K, Silver, Stainless, and other materials, there is a groove to attach a ceramic stone on the back of the product is characterized in that it is easily combined through the bonding process. As shown in FIG. 2, the finished functional jewelry product can be obtained through the combination of a ceramic stone and a pendant for a necklace. Figure 3 shows an example applied to the necklace. Such ceramic stones and pendants can increase the value of various products by applying the design desired by consumers.

Through the embodiment of the product developed by the present invention will be described the performance of the ceramic stone based on the data certified by each authorized institution.

<Example>

Functional powder (40wt%), elvan (30wt%), clay (20wt%), and alumina (10wt%) are added to the ball mill, and then the appropriate amount of water is supplied together to carry out the first mixing and grinding process for 30 hours. . After mixing and grinding, the moisture content is adjusted to 3wt% or less through an instant drying system to remove moisture. 5 wt% of the organic binder was added to the powder thus prepared, and the second mixing process was performed for 16 hours. After completion of the second mixing process, aged at room temperature for 24 hours. After maturation, the raw material is finished into ceramic stone through molding and sintering process in Table 2.

After the completed ceramic stone and pendant were combined and finished as a necklace product, the temperature of the skin surface in contact with the ceramic stone was increased by measuring the image before and after wearing it on the human body. This is an active phenomenon of blood circulation, showing that ceramic stone is affecting metabolism.

In addition, only by wearing the product, negative ions and far-infrared rays are quickly absorbed by the human body to help regulate blood rhythms to help blood circulation and make mind and body relaxed. Electroencephalograms were measured before and after wearing the product, and negative ions were found to be effective in increasing the body's condition by increasing brain alpha wave activity. Table 3 shows the results of measuring far-infrared emissivity and anion radiation measured by the Far Infrared Association.

division Emissivity Radiation energy (W / ㎡ · ㎛, 37 ℃) Negative ion Example 0.925 3.57 × 102 1220ea / cc
