Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to a pearl nucleus, jewelry such as rings, earrings, necklaces and bracelets, and beads.
Alternatively, it relates to a cured product that can be used as a building material or the like.

[0002]

BACKGROUND OF THE INVENTION Pearls include aragonite (a type of calcium carbonate), conchiolin (a type of protein) and water.
The pearl nucleus used was a naturally-occurring one obtained by polishing the shell of a blubber, but recently it has become less and more expensive, and the development of a pearl nucleus to replace the shell has been demanded.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cured product which can be used not only as a pearl nucleus but also as an accessory or a beads and as a building material.

[0004]

Means and Actions for Solving the Problems The hardened material of the present invention which meets the above-mentioned object is obtained by adding one or more of water, protein solution and starchy solution to slaked lime, or by further adding a coloring agent and a transparent agent. A mixture of 1 or 2 or more of a photogenic substance, synthetic resin emulsion, and white Portland cement is cured by a chemical reaction such as carbonation, and then polished and polished.
The feature is that the surface gloss is formed by rubbing and polishing. When water is added to slaked lime and kneaded and molded, it reacts with carbon dioxide gas in the air to form a calcium carbonate hardened product, and when slaked lime is mixed with a protein solution and / or a starch solution, kneaded and molded. Even if left to stand naturally, it reacts with carbon dioxide in the air to become a protein and / or starchy calcium carbonate cured product. When an aqueous solution of potassium stearate is added and kneaded and molded, slaked lime reacts with carbon dioxide in the air and also reacts with potassium stearate to form calcium stearate, which becomes a water repellent cured product. These hardened products become colored hardened products when a coloring agent is added to the raw material, and when white Portland cement is added, the strength and the specific gravity become large due to gel formation. If hydrated lime does not elute even when these hardened products are soaked in water due to carbonation, etc., the surface gloss that can be obtained by polishing is hard to disappear, and if hydrated lime elutes due to insufficient reaction, in the presence of the reaction solution. Then, if you react sufficiently while rubbing and polishing so that the eluate and reaction product do not adhere, the gloss will not disappear easily. When a light-transmitting substance or a synthetic resin emulsion is added, the surface gloss produced by polishing or the like feels as if it has light-transmitting properties.

Example 1 To 500 g of slaked lime, 340 g of water was added and kneaded to make a mixture, and a ball and a plate having a diameter of about 1 cm were made. After 2 to 10 days, polishing was carried out and calcium carbonate having a surface gloss was obtained. A cured product was obtained. Example 2 Instead of 340 g of water of Example 1, 60 g of egg white and 300 g of water
Mixed egg white solution 340g / Oyster 400
400g of water was added to g and mixed with it, and 340g of oyster extract solution that was strained with a cloth, 340g of low-fat milk, 340g of a heated aqueous solution containing 5/70 gelatin, soymilk 380
Mixtures are made using different g protein solutions and have a diameter of 1
A ball and a plate of about cm were made, and after 2 to 10 days, polishing was carried out to obtain 5 kinds of protein calcium carbonate-based cured products having surface gloss. Example 3 In place of 340 g of water of Example 1, a funori content of 1/12
340 g of heated aqueous solution of Funori and 400 g of Tokoroten heated to 400 g of Tokoroten, or a mixture of different starchy solutions of 350 g of heated aqueous solution having an agar content of 1/60 to make a mixture, and a ball with a diameter of about 1 cm A plate was made, and after 2 to 10 days, polishing was carried out to obtain three types of starchy calcium carbonate-based cured products having surface gloss. Example 4 To 300 g of egg white, 600 g of water and 30 g of sodium bicarbonate were added and stirred to prepare a solution, and 800 g of the solution was dissolved in 1800 slaked lime.
Add g to make a mixture, make a ball and a plate with a diameter of about 1 cm, soak it in hot water at a temperature of 80 ° C after 3 days, take it out after 1 day, and then carry out polishing shaving after 5 days to make a calcium carbonate system with surface gloss. A cured product was obtained. Example 5 Instead of 340 g of water of Example 1, potassium stearate 3
% Of aqueous solution 340g to make a mixture, diameter 1cm
A ball and a plate of a certain size were made, and after 2 to 10 days, polishing was carried out to obtain a calcium carbonate-based cured product having surface gloss and exhibiting water repellency. Water repellency is due to the formation of calcium stearate. Example 6 Examples 1 to 5 were carried out by further adding one or more of a colorant, a light-transmitting substance, and a synthetic resin emulsion white Portland cement. The spheres of Examples 1 to 6 were formed by rolling the mixture as it was or rolling the spheres while sprinkling slaked lime on them.

Example 7 Balls of Examples 1 to 6 were produced using a ball-forming machine composed of a cylindrical side wall and a rotating plate at the bottom. Powder such as slaked lime was supplied onto the rotating plate to rotate the rotating plate, and balls were formed while spraying water or a solution. This is to make balls by rolling with water or a solution as a core while adhering powder to the outside and pressing against the side wall with centrifugal force to make a multi-layered ball. May be used. Water or solution and powder adhere to the circumference of the solid spheres and become multi-layered and gradually increase in size. When a heat denaturing substance (except egg white) such as a gelatin solution, an agar solution, or a tocorotene solution is used, it is desirable to make a ball at a temperature denaturing temperature or higher. Example 8 The spheres of Examples 1 to 6 were extruded by an extrusion molding machine to form a cylindrical molded product, which was then sphered by a ball-forming machine. Example 9 The admixtures of Examples 1 to 6 were press-molded or centrifugal-forced and molded into an arbitrary shape such as a spherical shape, a plate shape, or a cylindrical shape. Example 10 The surface gloss-forming spheres prepared in Examples 1 to 9 have a concentration of 0.5%.
Salt water (any kind of potassium stearate aqueous solution, silica sol aqueous solution, etc., as long as it reacts with slaked lime) or a pan-type mixer to prevent eluates and reactants from adhering to the sphere surface in the presence of water, The one that was rubbed while rolling with a rotary drum or a rotary plate for 48 hours did not lose its luster even when immersed in water for 24 hours. Moreover, similar results were obtained by rolling not only balls but also balls made of other ceramics. If the cured product is a plate with surface gloss, rub or wipe the plate surface with a rotating brush or rotating mop for 48 hours in the presence of water or an aqueous solution of a substance that reacts with the eluate such as salt water. It was Even this was soaked in water for 24 hours, the gloss did not disappear. When water or salt water is contaminated with the eluate or the reaction product, it is preferable to replace and work. Example 11 The cured products of Examples 1 to 9 are molded in a carbon dioxide gas atmosphere, cured in a carbon dioxide gas atmosphere, or cured in a solution that reacts with slaked lime such as carbonated water to react with slaked lime, and slaked lime. The product that did not elute was polished and the product did not lose its luster even when immersed in water.

For the polishing and polishing in the examples, it is possible to use polishing powder pressure spraying, polishing powder slurry pressure spraying, pressure water spraying and the like. For the ball formation, solid particles such as cement paste may be used as the core to form the ball. A cured product layer of the present invention is formed around the core. A slaked lime-based admixture may be laminated on ordinary concrete or mortar and cured, and then polished and polished. It is preferable that a heat-modified substance such as a gelatin solution or a starch starch solution is kneaded with slaked lime or the like in a melted state or a gelatinized state. Good mixing is achieved by heating powder such as slaked lime. When the cured product is soaked in water or taken out, carbonation is fast. When used for the pearl nucleus, it is recommended to use the shellfish extract used for the protein solution.

EFFECTS OF THE INVENTION Since the cured product of the present invention is reacted with carbon dioxide gas to the extent that slaked lime is not eluted, it does not lose its luster even when soaked in water or seawater, and not only the pearl nucleus but also various accessories and beads. -It can also be used for various shaped objects such as statues and building materials, and those coated with pearl essence become artificial pearls. In addition, it is possible to cultivate nucleated pearls by transplanting small pieces of mantle of the pearl oysters and hardened material together into the gonad of the pearl oysters, and also to cultivate nucleated pearls. It is also possible to insert a hardened material between the mantle and the shell to make a half-pearl or half-pearl jewelry.
