There is a problem that it is difficult to obtain a hydraulic material having an excellent appearance. Further, it is not considered to add a biological organic substance such as protein or starch, and even if it is added, there is a problem that the curing speed is slow and the strength does not appear, which is not practical.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a hydraulic material that solves the above-mentioned problems of the prior art.

[0004]

[Means and Actions for Solving the Problems] The first hydraulic hardening substance of the present invention is a hydraulic hardening raw material, a gelatin solution in which water is added and hot melted, a glue solution in which water is hot melted, and collagen. Solution-milk or its solution- skim milk or its solution-casein solution-egg white or its solution-soy milk or its solution-starch solution with water added-starch sugar solution-konjac solution-cellulose solution-nitrocellulose solution- One or more of viscose solution, silk fibroin solution, water-added agar solution, hot-melted tocorotene solution, water-added hot-melt Funori solution, pearl essence, pearl foil, and mica fine powder The mixture is cured. In the above hydraulic material, a solution such as gelatin coats the hydraulic hardening raw material, and when the temperature is lowered, gelatin or the like is modified and solidified, or the konjak solution reacts with alkali to form konjak, which makes it difficult to pass water. Perhaps because of this, white sinter does not occur or is difficult to occur. When air-cured, the reaction of the hydraulic hardening raw material is inhibited by organic substances and the hardening speed is slow.However, when the hardening is carried out at a temperature higher than the denaturation temperature of gelatin etc., the gelatin etc. will dissolve and the reaction of the hydraulic hardening raw material will be accelerated. , Faster curing. When a casein solution or the like is added, it reacts with the produced calcium hydroxide to reduce the generation of white sinter. In addition, by polishing, polishing or rubbing, it is possible to obtain a surface gloss that makes you feel translucent.
Those with pearl foil and pearl essence have a pearl-like surface gloss.

A second hydraulic material of the present invention is characterized in that the surface of the hydraulic material of the first invention is formed by polishing, polishing, rubbing or the like. This hydraulic material exhibits a warm luster peculiar to biological systems and a pearl-like surface luster.

A third hydraulic material of the present invention is such that when the hardened hydraulic material is allowed to act on water or a solution that reacts with the eluate of the hydraulic material, no eluate is produced, or Until the reaction is complete, wipe off or use friction, rubbing, polishing, etc. between hydraulic substances to prevent the above-mentioned eluate or reactant from adhering, or react with water or hydraulic substance eluate. It is characterized in that the eluate or the reaction product is soaked in the above solution and the adhered product is removed by friction, rubbing, polishing, polishing or the like between the hydraulic substances. The hydraulic substance is rubbed or the like to prevent the eluate or the reaction product from adhering, or the adhering elution product or the reaction product is removed by polishing, etc. The occurrence of flower is reduced.

Example 1 Hot water at 80 ° C. was added to 50 g of gelatin to prepare a 320 cc solution, and 1000 g of white Portland cement was added thereto.
Was added and kneaded to form a plurality of spheres having a diameter of about 1 cm, while it was poured into a plastic mold to form a plurality of plates having a thickness of 1 cm, and the following was performed. The balls were made by kneading and kneading as they were, or were made by sprinkling with white Portland cement. When the plate was cured by air-drying for 5 days and soaked in water, the strength was low, but secondary white sinter did not occur. What was sealed and cured immediately after molding the plate and soaked in water after 5 days had low strength but did not generate secondary white sinter. Those subjected to steam curing at 60 ° C. for 10 hours in a closed chamber immediately after plate molding had surface gloss and high strength, and no white flower was observed even after soaking in water after 5 days. The one soaked in water one hour after the plate was molded was not soluble in water and did not collapse. What was sealed with a lid immediately after the plate molding and heated at a temperature of 60 ° C. for 10 hours had a high strength to some extent, and no white flower was observed even after soaking in water after 5 days. After 48 hours of plate molding, demolding and autoclave curing 2
The product applied for 4 hours had high strength, and white sinter did not occur even after immersion in water after 5 days. After air-drying curing for 48 hours after plate molding, sealing curing for 48 hours, sealing heating curing for 10 hours at 60 ° C, and steam curing at 60 ° C for 10 hours, hot water at 60 ° C Those that have been soaked in water and cured in hot water for 24 hours are
Even if it was soaked in water the next day, white flower did not occur, and the strength was further increased. The spheres after 48 hours of molding were polished to obtain surface gloss. However, the gloss disappeared when immersed in water. This is rolled on a rotating plate heated above the denaturation temperature to dissolve the gelatin in the surface layer, and the exposed cementum covered with the melted gelatin disappears even if it is soaked in water after cooling to room temperature. There wasn't. The spheres, which had been sealed and air-dried for 48 hours, were cured or steam-cured in hot water at 60 ° C., and the polished ones obtained a surface gloss that was translucent. Those coated with a resin or a hot-melt gelatin solution did not lose their luster even when soaked in water, and those coated with pearl essence exhibited a pearlescent color. (10) A large number of surface-gloss-forming spheres that have been polished to form a surface-gloss in a pan-type mixer in the presence of salt water or water having a concentration of 0.5x so that eluates and reactants do not adhere to the sphere surface. 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. Although salt water was used as an example of a substance that reacts with the eluate such as calcium hydroxide, the gloss does not disappear even when using a dilute aqueous solution of citric acid, an aqueous solution of silica sol, carbonated water, an aqueous solution of potassium stearate, etc. It was That is, the substance that reacts with the eluate is not limited to salt water. Moreover, similar results were obtained by rolling not only balls but also balls made of other ceramics. In the case of a plate that has been polished to form a surface gloss, water,
Alternatively, in the presence of an aqueous solution of a substance that reacts with an eluate such as salt water, the plate surface was rubbed or wiped with a rotating brush or a rotating mop for 48 hours. Even this was soaked in water for 24 hours, the gloss did not disappear. The surface gloss spheres or surface gloss plates that had been polished to form surface gloss were soaked in water or a reaction solution for 48 hours and taken out, but the gloss disappeared. Occurrence of sinter did not occur even when soaked in water, or sinter did not occur much. Polishing was performed by spraying with pressure water.

Example 2 Using a ball-forming machine having a cylindrical side wall and a rotating plate at the bottom and equipped with a heating device, white Portland cement
I made gelatin balls. White Portland cement is supplied onto the rotating plate to rotate the rotating plate, and the heating device below the rotating plate creates an atmosphere of white Portland cement and 60 atmospheres.
The mixture was heated to about 0 ° C., and a gelatin solution hot-melted at 70 ° C. was sprayed onto the mixture to form balls. This is one in which a gelatin solution is used as a nucleus to make a sphere, but a solid sphere may be used for the nucleus. The gelatin solution and white Portland cement adhere around the solid spheres and become larger gradually. When the heat source is cut off, the temperature drops and the spheres do not collapse. Example 3 To 50 g of gelatin, 300 cc of water was added and heated to 70 ° C.
(220 cc) of gelatin solution was added to the mixture, 1000 g of white Portland cement heated to 70 ° C. was added, and the mixture was kneaded and extruded by an extrusion molding machine to form a cylindrical molded product, which was then formed into balls by a ball-forming machine. Example 4 The kneaded product of the gelatin solution used in Examples 1 and 3 and white Portland cement was press-molded or centrifugally-molded to be molded into an arbitrary shape such as a spherical shape, a plate shape, or a cylindrical shape. Example 5 In Examples 1 to 4, the gelatin solution was replaced by a glue heating solution having a solid content of 15%, an agar heating solution having a solid content of 2%, a tocorotene solution having a volume of 80% by heating, and a solid content of 1%. Funori solution, egg white, upper solution obtained by adding 200 cc of water to 100 cc of egg white and stirring, milk, skim milk, casein solution, konjak solution (water is added to crushed konjak powder or konjak balls or grated and heated. Melted), collagen solution, starchy solution gelatinized by heating with water, starch sugar solution, soy milk solution, gum arabic solution, cellulose solution, nitrocellulose solution, viscose solution, silk fibroin solution, pearl essence, Pearl foil,
A mixture of two or more of these including mica fine powder and a gelatin solution was used. The polished ones using pearl essence, pearl foil, and fine mica powder produced a pearl-like luster, and the others produced a beautiful luster that was translucent. Example 6 Examples 1 to 5 are carried out by using a cement type such as Portland cement, a gypsum type, a slag slaked lime (quick lime) type, and a silica sand slaked lime (quick lime) type, or by adding an aggregate or a pigment or dye. Was added. Titanium dioxide and calcium carbonate were used as pigments, and animal dyes and / or vegetable dyes were used as dyes. Example 7 The molded products of Examples 2 to 6 were subjected to steam curing, heating curing, warm water curing, autoclave curing, etc. to accelerate the hydration reaction in a state where the organic matter was dissolved and promote gel formation. The steam-cured milk was slow to cure and turned yellow.

Example 8 A large number of surface-gloss-forming spheres formed by polishing with cement mortar or cement paste to form a surface gloss were treated with spheres of eluate or reactant in the presence of salt water or water having a concentration of 0.5%. What was rubbed while rolling for 48 hours with a pan mixer, a rotary drum, a rotary plate, or the like so as not to adhere to the surface did not lose its luster even when immersed in water for 24 hours. Although salt water was used as an example of a substance that reacts with the eluate such as calcium hydroxide, the gloss was not lost even when using an aqueous solution of citric acid, an aqueous solution of silica sol, carbonated water, an aqueous solution of potassium stearate, or the like. That is, the substance that reacts with the eluate is not limited to salt water. Moreover, similar results were obtained by rolling not only balls but also balls made of other ceramics. In the case of a plate that has been polished mortar or concrete to create a surface gloss,
In the presence of water or an aqueous solution of a substance that reacts with the eluate such as salt water, the plate surface was rubbed or wiped with a rotating brush or a rotating mop for 48 hours. Even this was soaked in water for 24 hours, the gloss did not disappear. In the case of Example 1 as well, when water or salt water is contaminated with the eluate or the reaction product, it is preferable to replace it and work. The surface spheres or plates with the surface gloss formed by polishing hardened mortar or concrete were soaked in water or the reaction solution for 48 hours, and the gloss disappeared, but the adhered substances were removed by polishing. The surface gloss of the product was reproduced, and even if it was soaked in water, there was little or no white bloom. Polishing was performed by spraying pressured water.

Although the eighth embodiment has been described above, in the embodiment, polishing can be carried out by polishing powder pressure spraying, polishing powder slurry pressure spraying or the like. When removing those with reactants attached, pressure water that does not damage the glossy surface,
It can be performed by spraying abrasive powder having a lower strength than the glossy surface. When a dye is added, the addition of an animal dye and / or a vegetable dye can give a luster characteristic of a biological system. For the ball formation, solid particles such as cement paste may be used as the core to form the ball. In this case, the hydraulic material layer of the present invention is formed around the core. Further, it may be a plate-shaped laminated body formed by laminating general concrete or mortar and the hydraulic material of the present invention. The organic solution added to the hydraulic hardening raw material is included in the present invention even if it is not described, as long as it has the same effect on the protein-based solution, the starch-based solution, and the cellulose-based solution. Further, the solution referred to in the present invention includes an aqueous solution, an emulsion, or the liquid itself. Sprinkle uncured hydraulic substances with powder such as cement to make balls,
When the liquid is absorbed into the powder by laminating press, the ratio of water or liquid powder becomes small, and when water or liquid is replenished after it does not collapse with water or solution, the reaction proceeds and the strength is high. Obtain the substance. And, for those that do not produce coarse calcium carbonate in the surface layer due to sealed curing, sealed steam curing, water or hot water curing, autoclave curing, etc. that suppresses evaporation of water, a gloss that makes you feel translucency is generated by outer layer polishing, When coarse calcium carbonate is produced in the outer layer due to air-drying curing or the like, when the outer layer is removed and the inner layer is polished, a gloss that gives a light-transmitting property is produced. In addition, what was neutralized by autoclave curing,
It does not necessarily need to prevent white flower. In the above-mentioned examples, it is preferable to knead a gelatin solution, a starch starch solution, or the like that is thermally denatured with cement or the like in a melted state or a gelatinized state. Good mixing is achieved by heating powder such as cement. When adding a heat-denaturing solution to form a hydraulic substance in which white sinter does not occur, a solution having a concentration that solidifies when the solution is cooled was used. The solid content of the solution is 0.5% or more, preferably 0.5% to 15% of the hydraulic hardening raw material. Droplets were formed on the surface of the plate after molding when using a protein-based solution such as egg white or milk, a red-algal solution such as Funori solution, or a starch-based solution such as konjac solution or potato starch solution. This seems to be one factor that can prevent white sinter and can be used for underwater concrete.

[0012]
