Description

DETAILED DESCRIPTION OF THE INVENTION Object of the invention Industrial field of the invention is the floor of any building requiring a fireproof structure,
Regarding panel materials (outer wall components) that are used as roof and wall materials and replace concrete and ALC plates, especially those related to panel materials that have reduced water absorption and do not require painting, tiling, etc. is there.

Conventional Technology Conventionally, concrete is a mixture (cement 10, silica sand 3
No. 0, gravel 60) was kneaded with water and hardened at room temperature, and ALC plates were added to the compound (cement, silica sand, limestone) with a foaming agent, kneaded and molded with water, and then autoclaved (high temperature, high pressure, It was cured in a steam pot) and cured,
Since both the concrete and the ALC plate are hardened by utilizing the hydraulic properties of cement limestone, when heated at 900 ° C. or outside, the lime content of the cement is whitened, and the sand grains (silica stone) in the mixture ) Had a defect that the transformation of the crystal structure started by heating, the transformation expansion peculiar to silica stone occurred, and the collapse of the concrete body started at high temperature due to fire or the like.

In addition, since general cement products use sand grains, there are gaps between the internal and external materials, and since it is a coarse mould, it has the drawback of absorbing water. Therefore, it takes time to tile and paint. It is necessary, it becomes heavy with tiling, and it has to be repainted every 5 years with paint painting,
It had a defect that the tiles tended to come off due to shrinkage due to water absorption.

Further, the weight-reduced ALC plate has a specific gravity of about 0.5 when dried, but has a drawback that it absorbs water at room temperature to about 0.8, and when tiled, it becomes 1.2 or more. It was

[Structure of Invention]

Means for Solving the Problems In view of such a point, the present invention, cement, silica sand, glaze, blended with a foaming agent consisting of Styrofoam, kneading with water, after molding and curing, dried, baked to be formed, cement ,
A mixture of silica sand, glass fine powder, and if necessary, feldspar fine powder and a foaming agent consisting of glaze and Styrofoam, kneaded with water, molded and cured, dried and baked to form a molded body, and a molded body after drying. The above is provided by applying a glaze to the surface of the product, forming it by baking, and styrofoam arranged in a wire mesh form, curing, drying, and baking, and providing a panel material in which reinforcement holes and mortar are filled in the hole. It does not eliminate the drawbacks.

Working The present invention is to form concrete by forming a foaming agent consisting of cement, silica sand, glaze or glass (solvent), and styrofoam as a raw material, firing and coating silica sand with a solvent to magnetize (vitrify) magnetism. The construction of a completely different type of magnetic nitrification (porcelain) improves waterproofness and eliminates the need for painting, tiling, etc., while reducing weight, improving heat resistance due to fire, etc. By applying glaze on the surface, the waterproofness is further improved, the aesthetic appearance is improved, and reinforcing is done by inserting reinforcing bars into the panel material.

EXAMPLE An example of the present invention will be described below with reference to the drawings. In the panel material 1 according to the present invention, a foaming agent made of Styrofoam having a diameter of about 1 mm is added to a mixture, kneaded with water, molded and cured, and then dried. The specific gravity of the panel material 1 is about 1 to 20 by baking at 1150 ° C. to 1200 ° C. and magnetizing to form magnetite. The composition of the panel material 1 is 10 to 20% of cement, 80 to 70% of silica sand, and glaze ( 10% of a glassy solvent).

It should be noted that the foaming agent composed of the styrofoam is burned and vaporized at about 300 ° C. to form voids, thereby reducing the weight, and each void is independent and effective heat insulation, sound insulation,
It exhibits sound insulation.

The glaze is represented by RO and R ₂ O.xR ₂ O ₃ .yRO ₂ (Zegel formula), and RO and R ₂ which are base components.
O is Na ₂ O, K ₂ O, CaOMgO, TiO _2, etc., R ₂ O
₃ is Al ₂ O ₃ and RO ₂ is SiO _{2 which} is often used, and SiO ₂ is the main component as a glaze.

By adding glaze (glass medium solvent) to the mixture and firing it at high temperature, the lime content in the cement and the glaze react and eutectic, forming a melt and covering the sand grains and the role of sand grain mutual bonding. In addition, the alkali content of the melt that coats the silica sand grains reacts and erodes and melts on the surface of the silica sand grains, and during the expansion and expansion movement of the silica stone at each temperature, it is a cooling solidified body, that is, a magnetic nitrification body while flexibly responding. make.

In short, the lime component contained in the cement in the molded body is eutectic with the glaze, and part of it becomes a melt, which erodes the surface of the silica sand grains and confines the expansion of the silica sand, and the crystal form transition peculiar to silica stone due to each temperature. It has the effect of being performed in the coating of the glaze, the crystal transition motion ends with cooling, and together with the glaze that coats the silica sand grains, a magnetic nitrification body (porcelain) completely different from concrete is constructed.

As shown in FIG. 6, the transformation expansion of quartz, which is a type of silica stone, has different expansion rates during heating and cooling and causes a rapid transformation expansion at the αβ transition point at a specific temperature (573 ° C.). , These are done in the glaze and the sand grain interconnections are not compromised.

Incidentally, the general porcelain tile is usually fired at 1200 ° C. to 1250 ° C., and shrinkage of 8 to 11% is customary. However, since the transformation expansion of the silica sand is performed in the melt as described above, it is the same as the present invention. In the case of a large plate, the increase in shrinkage is directly proportional to the yield of the product, so that the target of "zero" is almost achieved during the sintering process.

Silica sand is originally inexhaustible in Japan, and cheap silica sand from Australia is imported, but it could not be used for ceramics due to its lack of stickiness, but according to the panel material 1 of the present invention, silica sand is also a baked product. It can be used for

Next, as the composition of the second invention, white cement 20
%, Silica sand 60%, glass fine powder 20%, and if necessary, glass fine powder 20% instead of glass fine powder 10%, feldspar fine powder 5%, and glaze fine powder 5%.

The feldspar fine powder is collected from potassium feldspar and contains SiO ₂ as a main component and K ₂ O.
The same ingredient as the glaze of the invention of 1) may be used.

In addition, both the glaze of the first and second inventions and the glass fine powder were made of SiO.
_The eutectic point may be lowered by using a base component containing ₂ as a main component, and Zn, Ba, and Mg may be added in a small amount to the glaze to further lower the eutectic point.

In addition, the edges of glass products are cut after molding, and a large amount of waste is generated, and some are reduced to glass raw materials, but most of them are crushed into waste, and some of them are roads. In the present invention, glass fine powder, which has been reused for the above slip prevention and which is difficult to dispose when producing such crushed glass, is used in the present invention to reduce the cost.

In addition, before firing, a glass glaze equivalent to a ceramic tile is applied to the molded body and covered, and fired to form a glassy film on the surface of the panel material for waterproofing, which is comparable to the tiled wall surface. And a free color effect can be obtained.

In addition, at the time of pouring the mold, a rod-shaped expanded polystyrene that is thicker than the reinforcing bar is arranged in a wire mesh shape, and after injection molding, firing
Polystyrene evaporates and disappears, giving an arbitrary cavity,
After firing, the reinforcing bars 2, 2a ... Are inserted and filled with mortar.

Since iron melts at around 1200 ° C., it cannot be added from the beginning before firing, and even if it is inserted after firing as in the present invention, a predetermined strength can be sufficiently obtained.

Styrofoam (foamed polystyrene) for weight reduction or reinforcing rebar is made by foaming a styrene resin made of carbon and hydrogen as a base material, so it will be
It only burns carbon dioxide and water vapor when it burns at about 00 ° C to 400 ° C, and does not generate toxic, harmful, or corrosive gas such as chlorine gas or cyan gas (hydrocyanic acid gas) like vinyl chloride, resin, and sawdust. In addition, since it contains a large amount of air because it is foamed about 50 times, incomplete combustion is unlikely to occur, and the amount of carbon monoxide generated in the case of incomplete combustion is slightly higher than that of wood, paper, etc. And the amount of gas generated is the smallest.

Next, the operation of the panel material according to the present invention will be described. Cement, silica sand, glaze or glass (solvent) is used as a raw material, fired, and silica sand is coated with a solvent to magnetic nitrify (vitrify). , A magnetic nitrification body (porcelain) that is completely different from concrete is constructed to improve waterproofness so that painting and tiling are not required, and it is also lightened and heat resistance due to fire etc. is improved. By coating the surface of the material 1 with glaze, the waterproof property is further improved and the aesthetic appearance is improved, and the reinforcing reinforcing bars 2, 2a ... Are put in the panel material 1 for reinforcement.

〔The invention's effect〕

In short, according to the present invention, a foaming agent composed of cement, silica sand, glaze, and expanded polystyrene is mixed, kneaded with water, molded and hardened, dried, and fired, so that conventional concrete and ALC boards have water absorbability. Therefore, tile application and paint application were required. However, since the panel material 1 of the present invention has no gaps between components and no water absorption, it does not require labor and is not heavy, and concrete is not required. , The ALC plate is whitened and disintegrates when exposed to high temperature, but the panel material 1 of the present invention does not deteriorate and is inexhaustible, and cheap silica sand can be used to reduce the cost, and foaming is also possible. The agent burns and vaporizes at about 300 ° C to form voids covered with glassy material to reduce the weight, and each void is independent and can exhibit effective heat insulation, sound insulation and sound insulation. , Again Agents in order consisting of polystyrene foam, the amount of safe and gas is also the smallest.

In addition, cement, silica sand, glass fine powder and, if necessary, a feldspar fine powder and a foaming agent consisting of glaze and Styrofoam were mixed, kneaded with water, molded and cured, dried and baked to form the first invention. By using the fine glass powder instead of the fine glaze, the glaze is expensive, but the fine glass powder is a waste product, so that the cost can be reduced.

Also, after the molded body was dried, glaze was applied to the surface of the molded body and baked to form a glassy film on the surface of the panel material to further ensure waterproofness and to form a tiled wall surface. You can get the same waterproofing and free color effect.

Further, since the styrofoam was arranged in the form of a wire mesh, and after molding and curing, it was dried and fired, and the reinforcing holes 2, 2a ... And mortar were filled in the hole, so that the panel material of the present invention is a pottery, so the hardness is Although it has sufficient elasticity and poor elasticity, its practical effect is extremely great, for example, the elasticity can be sufficiently ensured by inserting the reinforcing bars 2, 2a ....
