Description

Inorganic Building Materials Using Refused Glass And Method for Manufacturing The Same}

The present invention relates to an inorganic building material using a cullet and a method for manufacturing the same, and more particularly, to a building material used in ondol and other constructions containing ocher and jade in the cullet, and a manufacturing method thereof.

In general, building materials refer to materials used to construct or repair construction. The materials are classified into interior materials and exterior materials, and various materials such as stone, ceramic, cement, artificial stone, and chemical products are used.

Looking at the materials used in ondol so far from the building materials, the cement as a main component is mixed with water, such as gravel and sand and then used to cure for 3 to 4 days. As such, since water is added without a constant specification, it is usually called a wet ondol. However, this cement slab flooring has a long construction period, requires a lot of manpower, is harmful to the human body due to the radon gas generated from cement, has a low heat transfer efficiency, and has a long heating time for the ondol. There are many disadvantages, such as the need to rebuild after breaking.

In order to make up for the shortcomings of the existing wet ondol, a standardized dry ondol such as artificial marble or polymer concrete has recently been developed. However, dry ondol is not widely used because of high raw material cost, weak mechanical strength, and toxic gas generated during manufacture or combustion.

Another material used for building materials is ceramic or porcelain tiles. These tiles form clay, silicon, and feldspar, and then sinter them in a kiln to give mechanical strength. The sintering reaction of the tile mainly causes the feldspar to be melted first at 1100 ° C. in comparison with the other components and combined with the remaining unmelted particles. As such, the tile has a disadvantage of heating for a long time at a high temperature of at least 1100 ℃.

Another material used as a building material is a glass molding material containing cullet as a main component and alumina added. Since the glass molding material uses cullet, the manufacturing cost is low and the physicochemical properties are excellent. However, the alumina added as a reinforcing agent has a high hardness, which makes it difficult to micronize, and due to poor fusion characteristics with glass, it is difficult to manufacture, and has a weak thermal shock due to a large difference in coefficient of thermal expansion with glass.

Therefore, there is a demand for the development of new building materials that are cheap in construction materials used in the construction of buildings, are simple in the manufacturing process, have excellent physicochemical properties, and have beautiful surfaces.

The present invention is to solve the above problems, the object of the present invention is to meet the requirements as described above, the production is simple and inexpensive manufacturing cost, not only excellent physical and chemical properties but also high far-infrared radiation efficiency and surface It is to provide a new building material with beautiful cullet, ocher and jade added and a method of manufacturing the same.

Still another object of the present invention is to provide a dry ondol and a construction method using the building material.

In order to achieve the above object, the present invention provides an inorganic building material consisting of 40-90% by weight cullet powder, 5-50% by weight ocher, 5-40% by weight jade powder. There is also provided an inorganic building material which further comprises 5-40% by weight of ganbanite and / or 5-30% by weight of such aggregates.

If it is possible to add 1 to 7% by weight of a coloring agent to use such a building material as an exterior material, 0.1 to 10% by weight of a foaming agent such as sodium carbonate or strontium carbonate may be added to use as a heat insulating material.

The present invention and the concrete slab using the building material as described above; A heat insulation block constructed on top of the concrete slab, including cullet and ocher as main components, and a bubble generator added to uniformly disperse bubbles therein; A top plate installed on the insulating block and including cullet and ocher as main components; A hot water pipe inserted between the heat insulation blur and the top plate; It provides a method for constructing a dry ondol comprising a.

In the dry ondol, a groove formed in the upper part of the insulating block is formed, a hot water pipe is inserted therein, and a heat conductive plate made of a metal selected from copper alloy, aluminum alloy, and galvanized steel is installed on the hot water pipe to improve the thermal efficiency of the ondol. Can be.

Hereinafter, the present invention will be described in more detail.

In the present invention, the inorganic building material is used for construction of buildings and is classified into ondol, flooring, interior walling, exterior walling and other decorative materials, sanitary materials, kitchen materials, etc., depending on the purpose of use. And the like. The inorganic building materials classified as described above vary their mixed raw materials and additives according to their respective uses. Hereinafter, the mixed raw materials of the inorganic building material according to the present invention will be described.

The inorganic building material according to the present invention optionally contains jade and elvan rock in cullet and loess, and adds chamotte, silica sand or alumina as aggregate, and optionally adds coloring agent, binder or bubble generator according to each use. Are manufactured.

The cullet used in the present invention used cullet powder pulverized cullet generated in the production of glass products such as plate glass, tube glass, bottle glass or waste glass that can be easily obtained in the distribution process as a mixed raw material. The addition amount of the cullet powder is preferably 40 to 90% by weight. If the cullet is added at 40 wt% or less, the structure is not dense and the binding strength between other inorganic particles added together is difficult to be magnetized, and if it is added at 90 wt% or more, the molding becomes difficult due to the low viscosity during molding and shrinkage upon firing. This large size makes it difficult to adjust the dimensions of the final product.

Another mixed raw material, ocher, jade, and elvan were used as natural ores produced in nature, and the composition thereof is shown in Table 1 below.

division SiO ₂ Al ₂ O ₃ Fe ₂ O ₃ CaO MgO Na ₂ O K ₂ O Etc Cullet 70-73 1-1.9 - 7-12 1-4.5 13-15 - - ocher 50-60 8-25 2-4 4-16 2-6 - - 1-5 jade 40.3 0.3 0.54 24.3 21 0.01 0.07 13.48 Elvan 58-73 11-15 2.3-2 1.9-4.2 0.5 3.2 4.9-9 1.6

In case of yellow soil, it is added to increase the dry strength during molding by providing thermal moisturizing effect, far-infrared radiation effect during heating, and plasticity. When it is added below 5% by weight, the far-infrared radiation effect decreases and the bonding force is difficult, and the plastic strength is difficult. When the addition is more than 50% by weight, the firing temperature is increased, the firing time is long, the economical efficiency is low, the magnetization and densification are difficult, and the strength is lowered. Therefore, the addition amount of ocher is preferably 5 to 50% by weight.

Jade has a variety of colors, and the surface aesthetics of building materials are added to express the texture of natural stone and increase the far-infrared radiation efficiency at room temperature. When it is added below 5% by weight, the effect of far-infrared radiation is decreased at room temperature. It is difficult to express the texture and color, and when it is added more than 40% by weight, it is difficult to mold, so the plastic strength is lowered and the manufacturing cost of the material is increased, resulting in low economic efficiency. Therefore, the addition amount of jade is preferably 5 to 40% by weight.

In addition to the far-infrared radiation effect, elvan stone is added to adsorb sterilizing power and indoor air to express texture such as natural stone. When added above, the plasticity during molding is difficult to mold, so the plastic strength is lowered and the manufacturing cost is high, resulting in low economic efficiency. Therefore, the addition amount of the ganguerite is preferably 5 to 50% by weight.

In the case of chamotte, it is added to suppress the shrinkage during firing and to improve the strength of the material by acting as aggregate. When it is added below 5% by weight, it is difficult to adjust the size due to the shrinkage, and when it is added above 30% by weight, the firing temperature is Higher, longer firing time, high manufacturing cost, low economic feasibility. Therefore, the addition amount of chamotte is preferably 5 to 30% by weight.

The heat treatment temperature of the mixed raw material is changed according to the size of the particle size, the smaller the particle size, the lower the heat treatment temperature, the larger the particle size, the higher the heat treatment temperature. Therefore, the range of particle size is determined according to the heat treatment temperature of the building material to be manufactured. In the present invention, it is preferable to use a particle size within the range of 150-350 mesh for cullet powder, 50-500 mesh for ocher or jade, elvan or chamotte.

The colorant added in the present invention controls the color of the building material manufactured with the cullet as a main component. Color of building materials can be expressed in various ways such as white, brown, blue by selectively adding the colorants shown in Table 2. In the case of a colorant, it is preferable to add it in 1 to 7 weight% which can express the required color according to the kind of colorant.

color Type of colorant black Large amount of manganese + nickel oxide Red Serene + cuprous oxide + gold chloride blue Lactic acid copper + Cobalt oxide + Oxidation agent green Chromium Oxide + Copper Oxide yellow Silver nitrate + uranium + cerium (or oxide) amber Manganese Silicate + Iron Silicate + Carbon Sulfide grey A mixture of iron + manganese + copper and lead silicate milk white Crystal Stone + Fluorite (Fluorine Compound) + Titanium Oxide

The binder used in the present invention was added to facilitate the bonding of the particles of each mixed raw material when molding or firing the mixed raw materials. The binder used in the present invention may be selected from polyvinyl alcohol (PVA), polyethylene glycol (PEG), carboxymethyl cellulose (CMC) or methyl cellulose (MC) as the organic binder. The addition amount of the binder is less than 2% by weight, it is difficult to handle when the molding strength is lowered, and when it is added more than 13% by weight, it is difficult to pressurize by absorbing moisture, and the plastic strength is decreased during firing, so 2-13% by weight is added. It is preferable.

Water is added together when shaping the mixed raw materials by adding a binder, and when the amount of water is added below 3% by weight, the binder is not sufficiently dispersed and when it is added by more than 13% by weight, it is difficult to form the mixture. -It is preferable to add about 13% by weight.

The bubble generator used in the present invention was added to form a bubble in the manufactured building material to increase the thermal insulation effect. As the bubble generator, sodium carbonate (NaCO ₃ ) or strontium carbonate (SrCO ₃ ) was used. When the amount is added at 0.1 wt% or less, the bubble generation rate is considerably decreased, and when it is added at 10 wt% or more, the molding and plastic strength are significantly decreased. Since it is difficult, it is preferable to add in the range of 0.1-10 weight%.

The method of manufacturing a building material according to the present invention is to produce a product by molding the mixed raw material first and then firing the detailed manufacturing process for this will be described in detail in the following examples.

In addition, the present invention will be described in detail through the embodiment for the dry ondol also for the method of constructing the manufactured building material.

Embodiments of the present invention will be described for the ondol among the building materials and in particular the embodiment of the manufacturing method of the top plate and the heat insulating material among the materials used in the construction of the ondol first. In addition, a method of constructing a dry ondol using the top plate and the insulation prepared as described above will also be described.
